In engineering operation, in order to alert operators at an operation site, the operators are prevented from entering a dangerous area by mistake, so as to ensure operation safety, and warning objects such as warning slogans are usually arranged near the dangerous area of the operation site. Taking electric power maintenance as an example, because of the influence of factors such as incomplete five-prevention function of the switching device or energy dispersion of operators, dangerous phenomena such as the operator mistakenly enters a charged interval, mistakenly opens and closes a switch, and the like can occur. Therefore, in switching operations or service operations, red cloth curtains are commonly used to alert operators to make the operators clearly distinguish between a power outage service screen cabinet and an adjacent live non-service screen cabinet. Therefore, warning objects such as red cloth curtain, warning slogans and the like play an important role in ensuring the operation safety.
At present, whether the warning object is normally used is still determined by adopting a manual checking mode, so that the problem of low efficiency exists.

Detailed Description
The following describes embodiments of the present application in detail with reference to the drawings.
In the following description, for purposes of explanation and not limitation, specific details are set forth such as the particular system architecture, interfaces, techniques, etc., in order to provide a thorough understanding of the present application.
The terms "system" and "network" are often used interchangeably herein. The term "and/or" is herein merely an association relationship describing an associated object, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship. Further, "a plurality" herein means two or more than two.
Referring to fig. 1, fig. 1 is a flow chart illustrating an embodiment of the engineering operation detection method according to the present application. Specifically, the method may include the steps of:
step S11: an original image shot by the camera device on a working site is acquired, wherein the original image comprises a preset detection area.
In the present embodiment, the image pickup device may include a monitoring camera such as a dome camera, a card reader, or the like, and the present embodiment is not particularly limited herein. In practical application, the operation site may have a plurality of areas to be detected, in which case, in order for the image pickup device to automatically photograph the plurality of areas to be detected in the operation site, pose parameters set by a user on the image pickup device may be obtained, so as to set a plurality of preset positions for the image pickup device, so that the image pickup device photographs the operation site at the plurality of preset positions, thereby covering the whole operation site. Taking electric power overhaul as an example, the camera device can be arranged at the northeast corner of the electric power machine room, and when in detection, the southeast region, the northwest region and the southwest region of the electric power machine room need to be shot, so that three preset positions can be arranged for the camera device, and the camera device can respectively shoot towards the southeast region, the southwest region and the northwest region of the electric power machine room in the engineering operation detection process, so that an operation site can be covered.
In this embodiment, the preset detection area is an area that needs to be detected by engineering operation and is preset by a user, specifically, the preset detection area may be set as a rectangular area, and when the preset detection area is set by the user, coordinates of the rectangular area in the image may be set. In a specific implementation scenario, when the image capturing device is provided with a plurality of preset bits, the preset detection area may also be provided with a plurality of preset bits, and corresponds to the preset bits one by one. Still take electric power overhaul as an example, when the image pickup device is respectively provided with the three preset positions, so that the image pickup device can respectively shoot towards the southeast area, the southwest area and the northwest area of the electric power machine room in the engineering operation detection process, the three preset positions can be respectively provided with the electrified areas, and therefore, whether the electric power overhaul field meets the operation specification can be determined based on the position relation between the target object obtained through subsequent detection and the preset electrified areas.
In addition, similar arrangements may be made in other engineering applications such as construction engineering, communication engineering, etc., and this embodiment is not illustrated here.
Step S12: and performing target detection on the original image to obtain a target area corresponding to the target object in the original image.
In this embodiment, the target object is used to realize warning, and taking electric power overhaul as an example, the target object may be a red cloth curtain. In other engineering operations, the target object may also be other warnings, for example, in building engineering, the target object may also be a warning line, etc.; in the communication engineering, the target object may also be a warning sign, etc., which is not exemplified here.
In this embodiment, the specific mode of target detection may be a detection mode based on a neural network. For example, training the preset neural network by using the training image marked with the target object to obtain a trained preset neural network, and detecting the original image by using the trained preset neural network to obtain a target area corresponding to the target object. Or, the specific mode of target detection may also be a detection method based on traditional image analysis, for example, the color features of each pixel point in the original image are analyzed to obtain pixel points similar to the color features of the target object, then the pixel points are subjected to noise reduction and other treatments, and finally the minimum circumscribed rectangle of the pixel points after the noise reduction and other treatments is used as the target area corresponding to the target object. The present embodiment is not particularly limited herein.
Step S13: and determining whether the operation field accords with the operation specification or not based on the position relation between the preset detection area and the target area.
In one implementation scenario, when a coincidence region exists between the preset detection region and the target region, the target object is considered to be arranged in the preset detection region, the operation site is determined to be in accordance with the operation specification, otherwise, the operation site is determined to be out of accordance with the operation specification.
In another implementation scenario, when the preset detection area completely includes the target area, the target object is set in the preset detection area, and the operation site is determined to be in accordance with the operation specification, otherwise, the operation site is determined to be not in accordance with the operation specification.
In yet another implementation scenario, when the intersection ratio (Intersection over Union, ioU) between the preset detection area and the target area is greater than a preset intersection ratio threshold (e.g., 0.5), the target object is set in the preset detection area, the job site is determined to be in accordance with the job specification, otherwise, the job site is determined to be out of accordance with the job specification.
In a specific implementation scenario, when it is determined that the job site does not meet the job specification, preset alert information may also be output. In addition, when it is determined that the job site meets the job specification, preset safety information may be output, or no information may be output. The preset alarm information and the preset security information may include, but are not limited to: text, sound, images, etc., the present embodiment is not exemplified here. In addition, when the original image is subjected to target detection and a target area corresponding to a target object is not detected, preset alarm information can be directly output, so that the warning operation site is not in accordance with the operation specification.
According to the scheme, the original image shot on the operation site by the image pickup device is obtained, the original image contains the preset detection area, so that the original image is subjected to target detection, the target area corresponding to the target object for realizing warning in the original image is obtained, and whether the operation site accords with the operation standard or not is determined based on the position relation between the preset detection area and the target area, so that whether the operation site accords with the operation standard or not can be detected based on the original image shot on the operation site by the image pickup device, the operation site is not required to be checked manually, the detection efficiency can be improved, the probability of occurrence of omission is reduced, and the engineering operation detection quality can be improved.
Referring to fig. 2, fig. 2 is a flowchart illustrating an embodiment of step S12 in fig. 1. The method specifically comprises the following steps:
step S121: and carrying out threshold segmentation on the original image by utilizing a preset threshold related to the color characteristics of the target object to obtain an image to be detected.
In a specific implementation scenario, taking electric power overhaul as an example, if the target object is a red cloth curtain, a preset threshold related to the color characteristics of the red cloth curtain may be adopted to perform threshold segmentation on the original image, so as to obtain an image to be detected. In other application scenarios, and so on, this embodiment is not illustrated here.
In addition, since the RGB (Red Green Blue) color space is greatly different from the human eye perception, in order to make the definition of the color distance conform to the human visual characteristics, the present embodiment can also map the color space of the original image to the HSV (Hue Saturation Value, hue/saturation/brightness) color space before performing the threshold segmentation. In one specific implementation scenario, when the color space of the original image is an RGB color space, the color space of the original image may be mapped to an HSV color space by:
in the above formula, (R, G, B) represents an R-channel pixel value, a G-channel pixel value, and a B-channel pixel value of a certain pixel point in the original image.
In addition, the (H, S, V) may be mapped to the interval of 0-255, which is not described herein. In a specific implementation scenario, the preset threshold may include: in other implementation scenarios, the values may be other values, and the embodiment is not limited in particular herein. By using the preset threshold value, whether each pixel point in the original image mapped to the HSV color space meets the following conditions can be judged in sequence: whether the H-channel pixel value is in a preset H-channel threshold interval, whether the S-channel pixel value is in a preset S-channel threshold interval, and whether the V-channel pixel value is in a preset V-channel threshold interval are determined, if yes, setting the pixel value of the corresponding pixel point in the image to be detected as a first pixel value (for example: 255), otherwise, setting the pixel value of the corresponding pixel point in the image to be detected as a second pixel value (for example: 0). Specifically, the pixel value of the pixel point related to the color feature of the target object in the image to be detected is a first pixel value, and the pixel value of the pixel point unrelated to the color feature of the target object is a second pixel value.
Step S122: and counting the sum of pixel values of all pixel points in the upper left area of each pixel point in the image to be detected, and taking the sum as the pixel value of the corresponding pixel point in the first integral image corresponding to the image to be detected.
Referring to fig. 3 in combination, fig. 3 is a schematic diagram illustrating an embodiment of the process for obtaining the first integral map in fig. 2. As shown in fig. 3, P 1 Is the image to be detected, P 1 (i, j) is the pixel value of the pixel point positioned in the ith row and the jth column of the image to be detected, Q 1 Is a first integral image, Q 1 (i, j) is a pixel value of a pixel located in the i-th row and j-th column of the first integral image. The first integral image can be obtained based on the image to be detected by:
step S123: and carrying out morphological processing on the image to be detected by using the preset structural elements and the first integral image to obtain a target area corresponding to the target object in the original image.
The preset structural element in this embodiment is a two-dimensional matrix, where the value of the matrix element is 1, and the size of the matrix element may be 15×15, or may be 13×13, or 11×11, or 9*9, which is not specifically limited herein.
In one implementation scenario, the morphological processing of the image to be processed may be directly performed using preset structural elements. For example, when the preset structural element is used for performing corrosion morphological processing on the image to be processed, atoms (i.e. center points) of the preset structural element can be used for traversing target pixel points with pixel values of first pixel values in the image to be processed, when the pixel values of other pixel points in the size area of the preset structural element are the same as the pixel values of the target pixel points, i.e. the pixel values of the other pixel points are all the first pixel values, the pixel values of the target pixel points are reserved, and otherwise, the pixel values of the target pixel points are set to be second pixel values. Referring to fig. 4 in combination, fig. 4 is a schematic diagram of an embodiment of the morphological processing in fig. 2, specifically, fig. 4 is a schematic diagram of an embodiment of the etching morphological processing using a preset structural element, as shown in fig. 4, where the size of the preset structural element is k×k, the size of the image to be detected is w×h, the image to be detected after the etching morphological processing is shown in fig. 4, where a hatched pixel point indicates a target pixel point with a pixel value of a first pixel value, as shown in fig. 4, and burrs in the image to be processed can be eliminated through the etching morphological processing. However, the algorithm complexity of performing the corrosive morphological processing on the image to be processed by directly adopting the preset structural elements is O (w×h×k×k), the complexity is higher, and the processing load and the resource cost are higher.
In another implementation scenario, in order to reduce the complexity of the algorithm, reduce the processing load and reduce the resource overhead, the first integral image may be used to perform morphological processing on the image to be processed. Specifically, referring to fig. 5 in combination, fig. 5 is a flowchart of an embodiment of step S123 in fig. 2, which may specifically include:
step S1231: and carrying out corrosion morphological processing on the image to be detected by using the preset structural elements and the first integral image to obtain a first processed image.
Specifically, a first target pixel point with a pixel value being a first pixel value in an image to be detected can be determined, a second target pixel point corresponding to the first target pixel point in a first integral image is determined, a third target pixel point in the first integral image is determined based on the second target pixel point and the size of a preset element structure, then the pixel value of the third target pixel point is utilized to calculate the sum of pixel values of all pixel points in the size range around the first target pixel point, if the sum of calculated pixel values and the size of the pixel points are the first pixel value, the first target pixel point is considered to be not a burr/noise point, the pixel value of the first target pixel point is kept to be the first pixel value, and if the sum of pixel values and the size of the pixel points are not the first pixel value, the pixel value of the first target pixel point can be considered to be the burr/noise point, and the pixel value of the first target pixel point is reset to be the second pixel value.
In a specific implementation scenario, please continue to refer to fig. 3, as shown in fig. 3, the image P to be detected 1 Wherein pixel (i, j) is the first target pixel, and correspondingly, the first integral image Q 1 Wherein the pixel point (i, j) is a second target pixel point corresponding to the first target pixel point, the thick line black frame region is a size (k) region of a preset structural element, and the image P to be detected is calculated 1 The sum of pixel values of pixel points in the size region of the preset structural element in the first integral image Q can be utilized 1 The calculation is performed by first determining the first integral image Q using the size of the preset structural element 1 The first integral image Q can be first of all 1 Pixel point in lower right corner of size region of preset structural element of (a)Determining a first third target pixel point with a pixel value ofRepresenting pixel dot +.>The sum of the pixel values of all the pixel points in the upper left corner area is determined, and the other three third target pixel points are determined> The sum of the pixel values of all pixels within the range of the size (k x k) of the perimeter of the first target pixel (i, j) can be expressed as:
after calculating the sum S of the pixel values of all the pixel points within the range of the size (k) of the surrounding of the first target pixel point (i, j), the quotient of the sum S of the pixel values and the size (k) can be further calculated (i.e. ) If the quotient is the first pixel value, the image P to be detected is described 1 The pixel values of all the pixel points within the size (k x k) range of the first target pixel point (i, j) are all first pixel values, and the first target pixel point (i, j) can be regarded as not being a burr/noise point, and can hold the image P to be detected at the moment 1 The pixel value of the first target pixel point (i, j) is unchanged, otherwise, the first target pixel point (i, j) is described as a burr/noise point, and the image P to be detected is obtained 1 The pixel value of the first target pixel point (i, j) is reset to the second pixel value.
By using the integral graph to perform corrosion morphology processing, the algorithm complexity can be reduced to O (w×h), and the algorithm complexity is remarkably reduced.
Step S1232: and counting the sum of pixel values of all pixel points in the upper left area of each pixel point in the first processing image, and taking the sum as the pixel value of the corresponding pixel point in the second integral image corresponding to the first processing image.
In one implementation scenario, after the image to be processed is subjected to the erosion morphological processing, the dilation morphological processing may be further performed, and similarly to the above steps, a sum of pixel values of all pixel points in an upper left area of each pixel point in the first processed image may be counted as a pixel value of a corresponding pixel point in the second integral image corresponding to the first processed image. Reference may be made to the above related steps in this embodiment, and details are not repeated here.
Step S1233: and performing expansion morphological processing on the first processing image by using the preset structural elements and the second integral image to obtain a second processing image.
Specifically, each pixel point in the first processed image may be sequentially used as a fourth target pixel point, a fifth target pixel point corresponding to the fourth target pixel point in the second integrated image is determined, a sixth target pixel point in the second integrated image is determined based on the size of the fifth target pixel point and a preset structural element, the pixel value of the sixth target pixel point is used to calculate the sum of pixel values of all pixel points in the size range around the fourth target pixel point, if the sum of pixel values and the size of the fourth target pixel point are the second pixel value, the pixel value of the fourth target pixel point is set as the second pixel value, and if the sum of pixel values and the size of the fourth target pixel point are not the second pixel value, the pixel value of the fourth target pixel point is set as the first pixel value. The specific manner of determining the sixth target pixel point in the second integral image based on the fifth target pixel point and the size of the preset structural element, and calculating the sum of the pixel values of all the pixel points within the size range of the periphery of the fourth target pixel point by using the pixel values of the sixth target pixel point may refer to step S1231 in this embodiment, which is not described herein again. Unlike the etching morphological processing, the purpose of the expansion morphological processing is to expand an edge and fill a hole, so as long as there is a pixel whose pixel value is a first pixel value within a size range of a preset structural element, i.e., as long as the quotient of the sum of pixel values and the size is not a second pixel value, the pixel value of the fourth target pixel is set to the first pixel value, otherwise, if there is a pixel whose pixel value is a first pixel value within a size range of a preset structural element, i.e., if the quotient of the sum of pixel values and the size is a second pixel value, the pixel value of the fourth target pixel is set to the second pixel value, by which means the edge can be remarkably expanded and the internal hole is filled.
Step S1234: and determining the pixel value of each pixel point in the second processed image as a target connected domain of the first pixel value.
And after the image to be processed is subjected to corrosion morphological processing and expansion morphological processing, obtaining a second processed image, and at the moment, if the pixel value of a certain pixel point in the second processed image and the pixel value of a neighborhood pixel point are both the first pixel value, dividing the pixel point and the neighborhood pixel point into the same connected domain, traversing all the pixel points in the second processed image, and obtaining at least one target connected domain.
Step S1235: and acquiring the minimum circumscribed rectangle of the target connected domain as a target area.
And taking the minimum circumscribed rectangle of the target connected domain as a target area.
Different from the foregoing embodiment, the method includes performing threshold segmentation on an original image by using a preset threshold related to a color feature of a target object to obtain an image to be detected, and counting a sum of pixel values of all pixel points in an upper left area of each pixel point in the image to be detected as a pixel value of a corresponding pixel point in a first integral image corresponding to the image to be detected, so that morphological processing is performed on the image to be detected by using a preset structural element and the first integral image to obtain a target area corresponding to the target object in the original image, algorithm complexity can be reduced, processing time can be shortened, speed of target detection is accelerated, real-time detection of whether engineering operation is standard or not is facilitated, and timely alarm is performed when the engineering operation is not standard.
