Description
Technical Field
The embodiment of the application relates to the technical field of communication, and in particular, to a parameter configuration method and apparatus, an electronic device, and a storage medium.
Background
At present, engineers often configure fixed image acquisition parameters to a camera based on experience, so that the camera can operate in a fixed configuration after image acquisition services are turned on.
However, when the camera performs image acquisition with a fixed image acquisition parameter configuration, when a subsequent algorithm flow is required to perform subsequent characteristic analysis on a target object in an image, there is a problem that an image with a sufficient resolution cannot be provided for the algorithm. For example, in an application that requires the face recognition of the owner, if the camera outputs an image with a fixed small resolution to the algorithm for detection, the cut-out portrait will not provide a good face recognition accuracy; if the resolution is fixed to be high for detection, power consumption is wasted when no face appears. In addition, the real-time requirement of the instant response application cannot be met in time. If the camera outputs images at a fixed low frame rate, the algorithm is difficult to respond in time when the target attribute changes rapidly; if the camera outputs images at a fixed high frame rate, power consumption is wasted when no target object appears, and flexibility and accuracy of image acquisition parameter configuration are low.

Fig. 1 is a schematic flowchart of a parameter configuration method according to an embodiment of the present application. As shown in fig. 1, in the embodiment of the present application, the parameter configuration method mainly includes the following steps:
and S101, carrying out target detection on the target frame image.

And S102, analyzing the target object detected from the target frame image to obtain a target analysis result.
In the embodiment of the application, after the parameter configuration device performs the target detection on the target frame image, the detected target object can be analyzed, so as to obtain the target analysis result.
It should be noted that, in the embodiment of the present application, the parameter configuration apparatus may perform analysis of various types of attributes with respect to the target object, and the analysis result constitutes a target analysis result. The specific analysis content of the parameter configuration device can be set according to actual requirements and application scenarios, and the embodiment of the present application is not limited.
Specifically, in the embodiment of the present application, the target analysis result includes: the current image proportion of the target object, the parameter configuration device analyzes the target object detected from the target frame image to obtain a target analysis result, and the method comprises the following steps: acquiring a first detection frame containing a target object from a target frame image; and calculating the image area ratio of the first detection frame in the target frame image to obtain the current image ratio.
It is understood that, in the embodiment of the present application, the parameter configuration apparatus performs target detection on the target image frame, and the detected target object may be marked by a detection frame in the target image frame, where the detection frame is denoted as a first detection frame. The parameter configuration device may directly acquire the first detection frame from the target frame image, and calculate an image area ratio of the first detection frame in the target frame image, that is, calculate a ratio of the area of the first detection frame to the area of the target frame image, and obtain the ratio, that is, a current image ratio of the target object.
It is understood that, in the embodiment of the present application, the current image proportion of the target object is determined based on one frame image of the detected target object, that is, the target frame image, which reflects the situation that the target object is actually at one moment, and is actually a static attribute of the target object. The current image ratio is only an exemplary static attribute, and of course, the parameter configuration apparatus may also calculate other types of static attributes of the target object by using the target frame image according to other specific algorithms, as the target analysis result or a part of the target analysis result, which is not limited in the embodiment of the present application.
Specifically, in the embodiment of the present application, the target analysis result includes: the parameter configuration device analyzes the target object detected from the target frame image to obtain a target analysis result, and comprises: acquiring a historical frame image containing a target object; performing target tracking on a target object in the historical frame image and the target frame image to obtain a target tracking result; calculating the change rate of the preset type attribute of the target object by using the target tracking result to obtain the attribute change rate; the preset type attribute comprises one or more of the following items: object state, image area ratio, and plane position.
It is understood that, in the embodiment of the present application, before the target frame image is acquired, a historical frame image that also includes the target object may be acquired, and for this, the parameter configuration apparatus may acquire the historical frame image, so as to compare with the target frame image, and calculate the dynamic attribute information of the target object, that is, the change rate of the preset type attribute.

It should be noted that, in the embodiment of the present application, the parameter configuration device may obtain the target tracking result by using a multi-target tracking algorithm according to the target detection result in the historical frame image and in combination with the target detection result in the target frame image, so as to respectively calculate the change rate of the preset type number of the target objects in the detection frame for the target objects.
It should be noted that, in the embodiment of the present application, the parameter configuration apparatus calculates the change rate of the preset type attribute of the target object by using the target tracking result, where in a case that the preset type attribute includes the object state, the change rate of the state of the target object actually needs to be calculated, for example, a rate of gesture change is calculated in application of gesture recognition, in a case that the preset type attribute includes an image area ratio, the change rate of the area of the target object actually needs to be calculated, which can be used as auxiliary information for determining that the target object approaches the rate of the image acquisition device, and in a case that the preset type information includes a plane position, the motion rate of the target object actually needs to be calculated. The preset type attributes are only some exemplary attributes provided, and of course, other attributes may be set according to actual needs and application scenarios, and the embodiment of the present application is not limited.
It is to be understood that, in the embodiment of the present application, the calculating of the change rate of the preset type attribute of the target object is determined based on the multi-frame image in which the target object is detected, that is, the target frame image and the history frame image, and the change condition of the target object in a period of time is actually a dynamic attribute of the target object.
It should be noted that, in the embodiments of the present application, the above-mentioned are only some exemplary analysis manners of the target object and specific contents of the target analysis result, and the specific analysis manners and the target analysis results are not limited in the embodiments of the present application.
S103, configuring image acquisition parameters based on the target analysis result.
In the embodiment of the application, the parameter configuration device can configure the image acquisition parameters based on the target analysis result for subsequent image acquisition under the condition of obtaining the target analysis result of the target object.
Fig. 2 is a schematic diagram of an exemplary parameter configuration process provided in an embodiment of the present application. As shown in fig. 2, in the embodiment of the present application, first, after a target service is turned on, for example, after a target AON service is turned on, a camera is configured to be in a "low power consumption mode" according to image acquisition parameters of a low resolution and a low frame rate, and a graph is configured accordingly, then a target detection algorithm is performed on an acquired image to obtain a target detection result, if a target object is not detected, the camera is continuously configured to be in the image acquisition parameters of the low resolution and the low frame rate to graph, if the target object is detected, the target object is analyzed to determine a target analysis result according to the analysis result, wherein if image acquisition parameters of a high resolution and a high frame rate are determined based on the target analysis result, the camera is configured to be in a "high performance mode" according to the image acquisition parameters of the high resolution and the high frame rate, if the image acquisition parameters of the low resolution and the low frame rate are determined based on the target analysis result, then the camera is configured into a "low power mode" with image acquisition parameters of low resolution and low frame rate maintained.
Specifically, in this embodiment of the present application, as described in step S102, the target analysis result may include a current image ratio of the target object, correspondingly, the image capturing parameter may include a target image resolution, and the parameter configuring device configures the image capturing parameter based on the target analysis result, including: determining the first resolution as a target image resolution under the condition that the current image ratio is smaller than a preset ratio threshold; determining the second resolution as a target resolution under the condition that the current image proportion is greater than or equal to a preset proportion threshold; wherein the first resolution is higher than the second resolution.
It is understood that, in the embodiment of the present application, in the case that the target analysis result includes the current image proportion of the target object, the parameter configuration device may determine the image resolution that the image capture output image needs to achieve, that is, the target image resolution, based on the size of the current image proportion.
It can be understood that, in the embodiment of the present application, the parameter configuration device may obtain the preset ratio threshold, and if the current image ratio is smaller than the preset ratio threshold, the target object is characterized as a small target, in this case, a high-resolution image frame needs to be generated during image acquisition, so that the target object can be clearly displayed, so as to ensure the accuracy of subsequent image processing, for example, face recognition processing and other processing, and therefore, the first resolution with a higher resolution may be determined as the target image resolution; if the current image ratio is larger than or equal to the preset ratio threshold, the target object is represented as a large target, and in this case, the target object can be clearly displayed only by generating an image frame with low resolution during image acquisition, and meanwhile, the power consumption generated by image acquisition is reduced, so that the second resolution with lower resolution can be determined as the target image resolution.
It should be noted that, in the embodiment of the present application, the first resolution is higher than the second resolution, and the specific values of the first resolution and the second resolution may be preset according to actual needs and application scenarios, or dynamically updated by using a specific algorithm, which is not limited in the embodiment of the present application.
Specifically, in this embodiment of the present application, as described in step S102, the target analysis result may include a change rate of an attribute of the target object, and correspondingly, the image acquisition parameter may include a target image frame rate, and the parameter configuration device configures the image acquisition parameter based on the attribute analysis result, including: determining the first frame rate as a target image frame rate under the condition that the attribute change rate is greater than a preset rate threshold; determining the second frame rate as the target image frame rate under the condition that the attribute change rate is less than or equal to a preset rate threshold; wherein the first frame rate is higher than the second frame rate.
It is understood that, in the embodiment of the present application, in the case that the target analysis result includes a property change rate of the target object, the parameter configuration apparatus may determine, based on a magnitude of the property change rate, an image frame rate that needs to be reached by the output image during image acquisition, that is, the target image frame rate.
It can be understood that, in the embodiment of the present application, the parameter configuration device may obtain the preset rate threshold, and if the attribute change rate is greater than the preset rate threshold, the representation target object has a fast change speed, in this case, image output needs to be performed at a higher frame rate during image acquisition, so that the real-time requirement of the immediate response application can be met, and therefore, a first frame rate with a higher frame rate may be determined as the target image frame rate; if the attribute change rate is less than or equal to the preset rate threshold, the characteristic target object has a slow change speed, in this case, image acquisition only needs to output images at a low frame rate, and power consumption generated by image acquisition is reduced, so that a second frame rate with a low resolution can be determined as the target image frame rate.
It should be noted that, in the embodiment of the present application, the first frame rate is higher than the second frame rate, and specific values of the first frame rate and the second frame rate may be preset according to actual needs and application scenarios, or dynamically updated by using a specific algorithm, which is not limited in the embodiment of the present application.
Fig. 3 is a schematic flowchart of an exemplary process for configuring image acquisition parameters according to an embodiment of the present application. As shown in fig. 3, first, the parameter configuration device needs to obtain a target detection result of a historical image frame, and in combination with the target detection result of the target image frame, a target tracking result is obtained by using a multi-target tracking algorithm, so as to calculate change rates of different attributes for the target object, respectively, and determine whether to configure a higher frame rate according to a comparison between the change rates and a preset rate threshold, where the calculated content specifically includes, but is not limited to, the following: a rate of change in an object state of the target object, a rate of change in an image area ratio of the target object, and a rate of change in a plane position of the target object, that is, a rate of movement of the target object. In addition, the parameter configuration device may calculate an image area ratio of the target object in the target image frame, obtain a current image ratio, and compare the current image ratio with a preset ratio threshold to determine whether a higher resolution needs to be set. And finally, fusing the results to configure image acquisition parameters, thereby outputting image acquisition configuration.
