Technical Field

Background

In modern cities, monitoring equipment is distributed all over each corner of a street, and monitoring pictures obtained by the monitoring equipment can protect the safety of people and can also know some real-time information and the like.

Optionally, each module in the system for determining the location of the monitoring point may also be deployed in a distributed manner on different devices, which is not limited in this embodiment of the present application.

In addition, each module of the system for determining the position of the monitoring point in fig. 1 is a software module, and the naming of each module is based on the function naming of the software module.

Based on the system for determining the location of the monitored point shown in fig. 1, the method provided by the embodiment of the present application is further described below. It should be noted that, in the embodiment of the present application, the steps in fig. 2 may be executed by using a device such as a terminal, a controller, a server, and the like, and the execution subject of the embodiment of the present application is not limited herein. Fig. 2 illustrates a terminal as an execution subject.

Fig. 2 is a flowchart of a method for determining a location of a monitoring point according to an embodiment of the present application, where the method for determining a location of a monitoring point may include the following steps.

Step 201: and the terminal responds to the selection operation of the point location calibration control on the display interface to obtain the monitoring point data and the external data.

In order to enable the terminal to start the point location calibration program of the target monitoring point, the terminal needs to respond to the selection operation of the point location calibration control for the target monitoring point on the display interface, and obtain monitoring point data and external data through the data acquisition module in fig. 1. The position calibration control is used for calibrating the position information of the target monitoring point.

In a possible implementation manner, the above implementation manner for the selection operation of the point location calibration control on the display interface is: a map comprising a plurality of monitoring points is displayed on a display interface of the terminal. And the user performs trigger operation based on one monitoring point of the plurality of monitoring points displayed on the display interface. And the terminal determines a target monitoring point in response to the triggering operation. After the terminal determines the target monitoring point, the terminal displays a point location calibration control aiming at the target monitoring point. And the user performs selection operation based on the point location calibration control of the target monitoring point, and the terminal responds to the selection operation instruction of the point location calibration control of the target monitoring point so as to start a point location calibration program of the target monitoring point.

In another possible implementation manner, the above implementation manner of the selection operation for the point location calibration control on the display interface is: a map with a plurality of point location calibration controls is displayed on a display interface of the terminal, and any point location calibration control corresponds to one monitoring point. And the user selects and operates on the basis of a target point position calibration control in the multiple point position calibration controls displayed on the display interface. And the terminal responds to the selection operation of the target point position calibration control, and takes the monitoring point at the target point position calibration control as a target monitoring point so as to start a point position calibration program of the target monitoring point.

It should be noted that, the implementation manners of the two terminal responses to the point location calibration instruction for the target monitoring point are only optional implementation manners, and the embodiment of the present application is not limited.

Optionally, the monitoring point data is acquired by an image acquisition device at the target monitoring point, and the image acquisition device places the acquired monitoring point data in a local cache, or uploads the data to a background server for storage. Therefore, the implementation manner of the terminal acquiring the monitoring point data may be as follows: the terminal obtains the data of the monitoring point based on the local cache of the image acquisition equipment. Specifically, the terminal sends a request for obtaining the monitoring point data to a local cache memory of the image acquisition device, wherein the request for obtaining the monitoring point data carries an identifier of a target monitoring point. After receiving the request, the image acquisition equipment searches the monitoring point data corresponding to the target monitoring point in the local cache, returns the searched monitoring point data to the terminal, and the terminal receives the monitoring point data. Or the terminal acquires the monitoring point data based on the background server. Specifically, the terminal sends a request for obtaining the monitoring point data to the background server, wherein the request for obtaining the monitoring point data carries the identifier of the target monitoring point. After receiving the request, the background server searches the monitoring point data corresponding to the target monitoring point, returns the searched monitoring point data to the terminal, and the terminal receives the monitoring point data.

Optionally, the implementation manner of the terminal acquiring the external data may be: the external data may be obtained based on the internet. Specifically, an external data control is displayed on a display interface of the terminal, a user triggers the external data control through preset operation, and the terminal responds to the triggering operation aiming at the external control to acquire one or more external data on the internet. When there is one acquired external data, the following step 202 is performed. When the acquired external data is multiple, displaying a plurality of second images included in the multiple external data on a terminal display interface, and selecting one second image from the multiple second images by a user, wherein the external data is the external data corresponding to the one second image selected by the user from the multiple second images. The terminal performs the following steps of step 202 for selecting external data corresponding to one second image. The preset operation may be any one of a click, a slide, a touch, and the like. Optionally, the terminal responds to a trigger operation for the external control, obtains one or more pieces of external data from the internet, and filters the external data according to the data source or the image content, and displays the filtered second images on the terminal display interface. Optionally, external data of a data source with street view images, such as a hundred-degree map, may be selected; the image content may also be selected as external data of the scene class.

The user selects one of the plurality of second images according to the user's own intention. For example, the user wants to select the second image of the same type as the first image, and if the first image is an image of a cat, the second image selected by the user is also an image of a cat. The basis of how to select one second image from the plurality of second images is not limited, and the user can arbitrarily select the second image according to the intention of the user.

The external data can be data such as videos and images uploaded by individuals in the social platform, shop information contained in life software, and the like. And will not be described in detail herein. The implementation manner of the terminal acquiring the external data may specifically refer to the implementation manner of the terminal acquiring the monitoring point data, and is not described herein again.

Step 202: and the terminal determines the position information of the target monitoring point based on the first image and the second image.

The terminal determines a first image included in the monitoring point data and a second image included in the external data. And the terminal determines the position information of the target monitoring point based on the first image and the second image. The external data may further include first position information, where the first position information is position information of an image capturing device that captures the second image. The monitoring point data may further include shooting parameters of the image capturing device at the target monitoring point.

In step 202, the degree of association between the first position information and the position information of the target monitoring point can be determined directly based on the first image and the second image, so that the accuracy of determining the position information of the target monitoring point is improved.

Therefore, in a possible implementation manner, the implementation process of the terminal determining the position information of the target monitoring point based on the first image and the second image is as follows: and under the condition that the matching degree between the first image and the second image meets a first preset condition, determining the position information of the target monitoring point based on the first position information. And under the condition that the matching degree between the first image and the second image meets a second preset condition, determining the position information of the target monitoring point based on the first image and the shooting parameters. Wherein the first preset condition indicates that the first image and the second image are identical or partially identical. The second preset condition indicates that the first image and the second image are both different.

The determination basis of the matching degree between the first image and the second image comprises the judgment of the similarity between the content of the first image and the content of the second image. If the content of the first image and the content of the second image are identical, it indicates that the image capturing device at the monitoring point and the image capturing device capturing the second image may be the first image and the second image captured at the same position in the same scene. If the content of the first image and the content of the second image are partially the same, it indicates that the image capturing device at the monitoring point and the image capturing device capturing the second image may be the first image and the second image captured in the same scene but at different positions. In both cases, the position information of the target monitoring point is associated with the first position information.

Wherein the content of the first image comprises a plurality of objects appearing in the first image and the content of the second image comprises a plurality of objects appearing in the second image.

Therefore, the above implementation manner for determining the content of the first image and the content of the second image is as follows: and the terminal respectively carries out edge detection on the first image and the second image to obtain an object appearing in the first image and an object appearing in the second image.

The implementation manner of the terminal for performing edge detection on the first image and the second image is as follows: the terminal obtains the pixel value of the first image pixel point and the pixel value of the second image pixel point. And determining points with obvious brightness change in the first image according to the pixel values of the pixels of the first image, determining the pixels with obvious brightness change, and determining continuous pixels as the edge of the object appearing in the first image. And determining points with obvious brightness change in the second image according to the pixel values of the pixels of the second image, determining the pixels with obvious brightness change, and determining continuous pixels as the edges of the objects appearing in the second image.

The above-mentioned edge detection of the images is only an implementation manner that the determination of the object appearing in the first image and the object appearing in the second image is optional, and the determination of the object appearing in the first image and the object appearing in the second image may also be performed in other manners, such as an image segmentation network, an image recognition network, and the like, which are not described herein one by one. When the similarity between the first image and the second image satisfies the second preset condition, for example, the content of the first image is different from the content of the second image, which indicates that the first image and the second image captured by the image capturing device at the monitoring point and the image capturing device capturing the second image are not in the same scene. At this time, the position information of the target monitoring point and the first position information do not have any correlation.

Thus, the similarity between the content of the first image and the content of the second image can be classified into three cases, the first being that the content of the first image and the content of the second image are identical. Second, the content of the first image is partially identical to the content of the second image. Third, the content of the first image is different from the content of the second image. The following three cases are used to determine how to determine the location information of the target monitoring point.

(1) The content of the first image and the content of the second image are identical.

In a possible implementation in which the content appearing in the first image and the content appearing in the second image are identical, if the shooting angle of the first image and the shooting angle of the second image are identical, it cannot be said that the image capturing device at the monitoring point and the image capturing device capturing the second image are located at the same position, and it is also possible that the same scene is in the same orientation, but facing different distances of the content in the images.

Therefore, in this case, further comparison is required based on the size of the first image and the size of the second image. If the size of the first image is the same as that of the second image, the first image and the second image which are shot at the same position of the image acquisition equipment at the monitoring point and the image acquisition equipment for acquiring the second image in the same scene are shown. And at the moment, the terminal takes the first position information as the position information of the target monitoring point. That is, if the first preset condition is: and if the content of the first image is the same as the content of the second image, the shooting angle of the first image is the same as the shooting angle of the second image, and the size of the first image is the same as the size of the second image, the first position information is taken as the position information of the target monitoring point.

For example, a user a takes an image of a hangzhou building at a certain location and uploads the image to a social platform, the content matching degree of the image and a first image acquired by image acquisition equipment at a target monitoring point is extremely high, and the extremely high matching degree specifically means: when the content of the shot image of the Hangzhou building is the same as the content of the first image, the shot image shooting angle of the Hangzhou building is the same as the shooting angle of the first image, and the shot size of the image of the Hangzhou building is the same as the size of the first image, the geographic position where the user A sends the social dynamic state is considered to be approximately equal to the geographic coordinates of the target monitoring point. I.e. the location information of the target monitoring point.

The above implementation manner of determining the shooting angle of the first image and the shooting angle of the second image is as follows: the terminal establishes a three-dimensional coordinate system by taking the position of the monitoring point as an original point, establishes the three-dimensional coordinate system based on the first position information, forms a three-dimensional space corresponding to the target monitoring point and a three-dimensional space corresponding to the first position information, and determines the shooting angle of the first image and the shooting angle of the second image according to the three-dimensional space corresponding to the target monitoring point and the three-dimensional space corresponding to the first position information.

In addition, the above determination of whether the shooting angle of the first image and the shooting angle of the second image are the same may also be referred to as performing similarity matching on the shooting angle of the first image and the shooting angle of the second image. Specifically, the terminal may set an angle threshold for dividing whether the photographing angle of the first image and the photographing angle of the second image are the same. And when the difference value between the shooting angle of the first image and the shooting angle of the second image is lower than the angle threshold value, the shooting angle of the first image is the same as that of the second image. The difference between the shooting angle of the first image and the shooting angle of the second image exceeds an angle threshold, and the shooting angle of the first image is different from the shooting angle of the second image.

The implementation manner of the size of the first image and the size of the second image is as follows: the size of the image is also the size of the image frame, the terminal determines the size of the first image according to the length and width of the first image, and determines the size of the second image according to the length and width of the second image.

Further, the above-described determination of whether the size of the first image and the size of the second image are the same may also be referred to as performing similarity matching on the size of the first image and the size of the second image. Specifically, the terminal may set a size threshold for dividing whether the size of the first image and the size of the second image are the same. When the difference between the size of the first image and the size of the second image is greater than the size threshold, the size of the first image and the size of the second image are not the same. When the difference between the size of the first image and the size of the second image is less than the size threshold, the size of the first image is the same as the size of the second image.

If the first preset condition is: when the content of the first image is completely the same as the content of the second image, and one or more of the size of the first image, the size of the second image, the shooting angle of the first image and the shooting angle of the second image are different, determining a conversion relation between a three-dimensional space corresponding to the first position information and a three-dimensional space corresponding to the target monitoring point, and performing three-dimensional space conversion on the first position information based on the conversion relation between the three-dimensional space corresponding to the first position information and the three-dimensional space corresponding to the target monitoring point to obtain the position information of the target monitoring point.

It should be noted that, when the shooting angle of the first image and the shooting angle of the second image are different, in a special case, there may be a case where the size of the first image and the size of the second image are the same. For example, the first image and the second image are both the same regular sphere, and the resulting size is the same regardless of the angle at which the regular sphere is captured. However, in general, since irregularities are present in each scene, when the photographing angle of the first image and the photographing angle of the second image are different, the size of the first image and the size of the second image are substantially different.

For convenience of description later, a three-dimensional space corresponding to image acquisition is explained first.

The three-dimensional space corresponding to the first position information specifically includes: and a three-dimensional coordinate system established based on the first position information. For example, with the image capture device capturing the second image positioned at the origin o1, the depth of field is the z1 axis, where the z1 axis is perpendicular to the plane of the second image. The horizontal axis of the acquired second image plane based on the origin is the x1 axis, and the vertical axis of the acquired second image plane based on the origin is the y1 axis. And establishing a three-dimensional space corresponding to the first position information according to the three-dimensional coordinate system.

The three-dimensional space corresponding to the target monitoring point specifically includes: and establishing a three-dimensional coordinate system for the terminal based on the target monitoring point. The position of the monitoring equipment of the target monitoring point is taken as an origin o2, and the depth of field is taken as a z2 axis, wherein the z2 axis is perpendicular to the plane of the first image. The horizontal axis of the first image plane acquired by the monitoring device of the target monitoring point based on the origin is the x2 axis, and the vertical axis of the first image plane acquired by the monitoring device of the target monitoring point based on the origin is the y1 axis. And establishing a three-dimensional space of the first image according to the three-dimensional coordinate system.

As shown in fig. 3, fig. 3 is a schematic diagram of an image three-dimensional coordinate system according to an embodiment of the present application. In fig. 3, the position of the monitoring device of the target monitoring point is the origin o 2. The depth of the monitored picture is the z2 axis, i.e. the direction perpendicular to the image. The horizontal axis of the image plane acquired by the monitoring device at the target monitoring point based on the origin is the x2 axis, and the vertical axis of the image plane acquired by the monitoring device at the target monitoring point based on the origin is the y2 axis.

Based on the definition of the three-dimensional space, the implementation manner of determining the conversion relationship between the three-dimensional space corresponding to the first position information and the three-dimensional space corresponding to the target monitoring point is as follows: the terminal acquires coordinate points of a plurality of objects appearing in the second image in the three-dimensional coordinate system and coordinate points of a plurality of objects appearing in the first image in the three-dimensional coordinate system. And converting the coordinate points of the plurality of objects appearing in the second image and the coordinate points of the plurality of objects appearing in the first image, and obtaining a conversion relation through a plurality of conversion training.

Based on the conversion relation, the three-dimensional space conversion is carried out on the first position information, and the realization mode of obtaining the position information of the target monitoring point is as follows: and the terminal places the origin o1 of the three-dimensional coordinate system corresponding to the first position information and the position of the monitoring equipment of the target monitoring point on the same three-dimensional coordinate system as the origin o2 according to the space reconstruction and integration module to obtain the three-dimensional space under the same three-dimensional coordinate system. And then according to the conversion relation, the position information of the target monitoring point can be obtained. Wherein the transformation relationship includes a shift and a rotation of the coordinates.

(2) The content appearing in the first image is partially the same as the content appearing in the second image.

When the content appearing in the first image and the content appearing in the second image are partially the same, at this time, neither the photographing angle of the first image nor the photographing angle of the second image, nor the size of the first image nor the size of the second image may be the same. Therefore, a conversion relationship between the three-dimensional space corresponding to the first location information and the three-dimensional space corresponding to the target monitoring point needs to be determined, and three-dimensional space conversion is performed on the first location information based on the conversion relationship to obtain location information of the target monitoring point.

The specific implementation manner may refer to the related contents in (1), and will not be described herein again.

(3) The content appearing in the first image and the content appearing in the second image are both different, i.e. a second preset condition.

And when the content appearing in the first image and the content appearing in the second image are different, the fact that the image acquisition device at the monitoring point and the image acquisition device acquiring the second image do not shoot the first image and the second image in the same scene is indicated. At this time, the content displayed on the second image has no reference meaning for the terminal to determine the position information of the target monitoring point, and therefore it is necessary for the terminal to determine a reference object from objects appearing in the first image, and determine the position information of the target monitoring point based on the position information of the reference object and the photographing parameter.

In a possible implementation manner, the above-mentioned implementation manner for determining the reference object from the objects appearing in the first image is: the terminal determines all objects appearing in the first image as reference objects.

In another possible implementation, one object among all objects appearing in the first image is selected to be determined as the reference object. The selected reference object is an object capable of identifying a name. Such as shops, road signs, etc.

The above-mentioned implementation manner of selecting one object from all objects appearing in the first image to determine as the reference object is as follows: the terminal randomly selects one object among all objects appearing in the first image to be determined as a reference object. Or the terminal displays the object appearing in the first image in the form of an object list or in the form of an object image on the display interface, the user triggers based on one object in the object list or one object in the object image as a reference object through preset operation, and the terminal determines one reference object after detecting the triggering operation.

The above implementation manners of determining the position information of the target monitoring point according to the reference object may be divided into two types, and the first type is that in the case of determining the position information of one or more reference objects, the terminal determines the position information of the target monitoring point based on the position information of one or more reference objects and the shooting parameters. The second is that in case that the location information of one or more reference objects cannot be determined, the terminal determines the location information of the target monitoring point based on the names of one or more reference objects.

In the first implementation manner, the determining the position information of the reference object is implemented by: the terminal determines the identification information of one or more reference objects by using the analysis module, and acquires the position information corresponding to the identification information of the one or more reference objects on the third-party software according to the identification information of the one or more reference objects. The identification information of the reference object is the name of the reference object. For example, the terminal obtains the location information of the starbucks a-way shop from some service software according to the two identifiers, namely the starbucks a-way shop and the starbucks a-way shop.

The above implementation manner of determining the position information of the target monitoring point based on the position information and the shooting parameter of the reference object is as follows: since the reference object is an object appearing in the first image, the plane coordinate of the reference object in the two-dimensional coordinate system corresponding to the first image can be determined according to the relative position relationship between the pixel points in the first image, and the plane coordinate can also be referred to as the two-dimensional camera coordinate of the reference object. Furthermore, the position information of the reference object is also the position coordinates of the reference object in geodetic coordinates, which may be generally latitude and longitude. Therefore, based on the two-dimensional camera coordinates of the reference object, the position information of the reference object, and the photographing parameters, the conversion relationship between the aforementioned two-dimensional coordinate system and the geodetic coordinate system can be determined. Since the coordinates of the target monitoring point in the two-dimensional coordinate system are known (i.e. the origin of the two-dimensional coordinate system), knowing the transformation relationship between the two-dimensional coordinate system and the geodetic coordinate system and the coordinates of the target monitoring point in the two-dimensional coordinate system, the coordinates of the target monitoring point in the geodetic coordinate system, that is, the position information of the target position point, can be determined.

In the second implementation manner, the terminal determines the identification names of the one or more reference objects by using the parsing module, and if the position information of the reference object is not obtained according to the identification information of the one or more reference objects, the tag calibration module of the terminal obtains the tagging information of the reference object, and uses the tagging information of the one or more reference objects as the position information of the monitoring point. The annotation information of the reference object may be input by a user through a preset operation.

Further, the tag calibration module of the terminal may further obtain the position relationship between the labeling information of the reference object and different reference objects, and use the position relationship between the labeling information of the reference object and different reference objects as the position information of the monitoring point. The annotation information of the reference object and the position relation between different reference objects can be input by a user through preset operation.

The range of the position of the target monitoring point can be reduced through the position relation among the plurality of reference objects, so that a user can accurately determine the position information of the target monitoring point.

For example, as shown in fig. 4, fig. 4 is a schematic image diagram provided in the embodiment of the present application. In fig. 4, there are two reference objects, and the labeled information is starbucks and Huarun Wanjia, respectively. The position relation between the starbucks and the Huarun Wanjia is that the starbucks and the Huarun Wanjia separate a pedestrian path.

Step 203: and the terminal displays the position information of the target monitoring point.

The terminal marks the determined position information of the target monitoring point by using the label calibration module and displays the position information on a display interface of the terminal so as to be convenient for a user to check.

In summary, in the embodiment of the present application, the position information of the target monitoring point is determined through the first image included in the monitoring point data and the second image included in the external data. Therefore, the position information of the target monitoring point does not need to be manually collected and recorded on site of the target monitoring point, and can be directly determined according to the first image and the second image, namely, the position information of the monitoring point is determined based on the content identification of the images. Therefore, the manpower is saved, and the speed of determining the position information of the target monitoring point is increased.

The method provided by the embodiments of the present application is further explained below by taking fig. 5 as an example. Fig. 5 is a specific flowchart of a method for determining a location of a monitoring point according to an embodiment of the present disclosure.

The monitoring point data includes the monitoring point image data in fig. 5 and the internal parameters of the monitoring point, which are the shooting parameters. The external data is external data with longitude and latitude information.

2. And respectively carrying out similarity matching on the content of the first image and the content of the second image, the shooting angle of the first image and the shooting angle of the second image, and the size of the first image and the size of the second image by using an image analysis technology. That is, the image analysis technology is applied to primarily match the shot picture of the monitoring point with external data.

3. And calculating geographic information such as geographic coordinates of the monitoring points in different modes based on the initial matching result. That is, the content of the first image and the content of the second image, the shooting angle of the first image and the shooting angle of the second image, the size of the first image and the size of the second image are respectively subjected to similarity matching by using an image analysis technology, and the position information of the monitoring point is respectively determined according to different similarity matching degrees.

4. And marking the monitoring point based on the determined position information of the target monitoring point, and finishing marking.

In summary, in the embodiment of the present application, the position information of the target monitoring point is determined through the first image included in the monitoring point data and the second image included in the external data. Thus, the position information of the target monitoring point is determined according to the first image and the second image, and can be determined directly according to the first image and the second image, namely, the position information of the monitoring point is determined based on the content recognition of the images. The method and the device not only save manpower, but also accelerate the speed of determining the position information of the target monitoring point.
