Therefore, the problems of high cost and resource waste caused by the fact that the same monitoring camera cannot monitor all objects in a monitoring scene and a plurality of monitoring cameras need to be arranged in the monitoring scene in the related technology can be solved, and the effects of improving monitoring accuracy and saving resources can be achieved.
Alternatively, the execution subject of the above steps may be a terminal or the like, but is not limited thereto.
As an alternative embodiment, uploading the long frame data to a first image processor to identify a human object in the frame of image by the first image processor, includes: uploading the long frame data to a first image processor; the first image processor adjusts the frame of image according to the exposure duration of the character object in the frame of image and a first adjustment parameter to obtain a first image; the first image processor identifies the person objects in the first image and the number of the person objects, wherein the person object identification result comprises the person objects in the first image and the number of the person objects. In this embodiment, the first image processor may adjust the image according to an exposure time of the human object in the image. For example, if the exposure time of the human object in the image is too long, the exposure time may be adaptively adjusted so that the exposure time of the human object in the image is within a reasonable range. Specifically, a threshold range may be preset, and if the exposure duration of the person object in the image exceeds the threshold range, the exposure duration of the image is decreased so that the exposure duration of the person object in the image satisfies the threshold range, and the obtained person object in the first image may perform face recognition.
As an alternative embodiment, uploading the short frame data to a second image processor to identify the vehicle object in the frame of image by the second image processor, includes: uploading the short frame data to a second image processor; the second image processor adjusts the frame of image according to a second adjustment parameter and the exposure duration of the vehicle object in the frame of image to obtain a second image; the second image processor identifies the vehicle object in the second image and the number of the vehicle objects, wherein the vehicle object identification result comprises the vehicle object in the first image and the number of the vehicle objects. In this embodiment, the second image processor may adjust the image according to an exposure time period of the vehicle object in the image. For example, if the exposure time of the vehicle object in the image is too short, the exposure time may be adaptively adjusted so that the exposure time of the vehicle object in the image is within a reasonable range. Specifically, a threshold range may be preset, and if the exposure duration of the vehicle object in the image is smaller than the threshold range, the exposure duration of the image is increased so that the exposure duration of the vehicle object in the image satisfies the threshold range, and the vehicle object in the obtained second image may perform license plate recognition.
As an optional embodiment, the method further comprises: and uploading the long frame data and the short frame data to a third image processor, so that the third image processor adjusts the frame image according to a third adjustment parameter according to the exposure duration of the character object in the frame image and the exposure duration of the vehicle object in the frame image to obtain a third image. In this embodiment, as shown in fig. 3, the long frame data raw _ L and the short frame data raw _ S are transmitted to the third image processor ISP0, and image processing is performed. The third image processor may adjust the image according to an exposure time period of the human object in the image and an exposure time period of the vehicle. For example, in one frame of image, if the exposure duration of the person is too high and the exposure duration of the vehicle is too low, a value may be selected between the exposure duration of the person and the exposure of the vehicle as a third adjustment parameter, and the image may be processed using the third adjustment parameter to obtain a third image. Optionally, the first image processor and the second image processor perform automatic exposure, adjustment of exposure time and gain and aperture, and automatic white balance and other image processing, according to the requirements of the capture. The first image processing result comprises a first shutter shut1 and a first gain1 obtained in the process of recognizing the face in the image, and the second image processing result comprises a second shutter shut2 and a second gain2 obtained in the process of recognizing the license plate in the image. In this embodiment, the third image processor synthesizes raw _ L and raw _ S according to the ratio of shut1 and gain1 to shut2 and gain2, which can be referred to a conventional wide dynamic synthesis algorithm. Because the exposure of the long and short frames is controlled by the 1 route and the 2 route, the exposure control is not carried out on the 0 route, but other image processing can be carried out according to the requirement of a preview image, and the image obtained by debugging can be presented on a preview interface.
As an optional embodiment, the uploading the long frame data and the short frame data to a third image processor, so that the third image processor adjusts the frame image according to a third adjustment parameter according to the exposure duration of the person object in the frame image and the exposure duration of the vehicle object in the frame image, to obtain a third image, includes: the third image processor acquires a first adjusting parameter when the first image processor adjusts the frame of image and a second adjusting parameter when the second image processor adjusts the frame of image; the third image processor determines the third adjustment parameter according to the first adjustment parameter and the second adjustment parameter, wherein the third adjustment parameter is between the first adjustment parameter and the second adjustment parameter; and the third image processor adjusts the frame of image according to the third adjustment parameter to obtain the third image. In this embodiment, the third image processor may process the image according to the first adjustment parameter obtained in the process of processing the long frame data by the first image processor and the second adjustment parameter obtained in the process of processing the short frame data by the second image processor, so as to obtain the debugged image. Specifically, the third image processor may determine a third adjustment parameter according to the first adjustment parameter and the second adjustment parameter, where the third adjustment parameter may be a numerical value between the first adjustment parameter and the second adjustment parameter, and the third image processor processes the image using the third adjustment parameter to obtain a third image.
As an optional embodiment, the method further comprises: in a case where it is determined that the number of the human objects in the one frame image is larger than a first threshold value and the number of the vehicle objects is smaller than a second threshold value, displaying a human object recognition result output by the first image processor; in a case where it is determined that the number of the human objects in the one frame image is smaller than a first threshold and the number of the vehicle objects is larger than a second threshold, displaying a vehicle object recognition result output by the second image processor; and displaying a third image output by a third image processor in the case where it is determined that the number of the human objects in the one frame image is greater than a first threshold and the number of the vehicle objects is greater than a second threshold. In this embodiment, based on the original usage of the long frame and the short frame, a new usage scenario based on the long frame, the medium frame, and the short frame is added, wherein the third image output by the third image processor is the medium frame image. In the display of the web preview side, the output of the medium frame may be defaulted as the output of the screen. The corresponding images may also be output and displayed according to the number of human objects and vehicle objects in the image. When there are more person objects and fewer vehicle objects in the image, the person object recognition result output by the first image processor may be displayed. The vehicle recognition result output by the second image processor may be displayed when there are fewer character objects and more vehicle objects in the image. The third image output by the third image processor may be displayed when the number of the human object and the vehicle object in the image is equivalent. Specifically, the first threshold and the second threshold may be preset by setting a threshold, the specific value may be determined according to actual conditions, and the first threshold and the second threshold may be equal or different. For example, the first image processor outputs long frames for intelligent face analysis and counts the number of face frames a. And outputting short frames of the second image processor for intelligently analyzing the moving vehicle, and counting the number B of vehicle frames. If A and B are less than 3 respectively, the picture of the web end is displayed by using the middle frame picture output by the third image processor. If A and B are respectively larger than 3, the picture of the web end is displayed by using a wide dynamic picture with long frames fused with short frames. If A is more than 3 and B is less than 3, the picture of the web end is displayed by using the wide dynamic picture of the frame in the long frame fusion. If B is more than 3 and A is less than 3, the pictures of the web end are displayed by using the wide dynamic pictures of the frames in the short frame fusion. Although three frames are output, the three paths of ISP are corresponding, one path is used for long frames, the other path is used for short frames, and the other path is used for display output.
According to the method, the data of the preview interface and the intelligent snapshot are separated, so that the data of the preview and the intelligent snapshot are respectively debugged, the requirement of intelligent analysis is met, and the requirements of moderate brightness and more details in the process of viewing the preview interface can be met. The camera with a single sensor can realize the output and the function of three sensors, so that the camera has stronger function. One camera can be used as three cameras, so that the effects of reducing expenditure and saving resources can be achieved.
