Embodiment approach

[0047] The implementation of the above-mentioned step S132 includes: the first implementation, through the actual data recording and measurement, the target object (such as a pedestrian or vehicle) that usually needs to be detected can be obtained in the second video frame (that is, the original resolution image) Horizontal width and vertical width, where the horizontal width and vertical width in the image of the original resolution here can be recorded as (w_orig, h_orig); the above-mentioned target detection model needs to record the minimum size of the target object detected in the input image is (w, h), where w represents the horizontal width of the target object that the target detection model needs to detect in the input image, and h represents the vertical width of the target object that the target detection model needs to detect in the input image; then the scaling factor can be used formula Calculated, where scale represents the zoom factor, w_orig and h_orig repres...

Abstract

The invention provides a target detection method, a device, electronic equipment and a storage medium. The method comprises the steps of obtaining video data collected by a camera; extracting a first video frame and a second video frame from the video data; determining a regional image containing a remote target from the second video frame; performing target detection on the first video frame by using a target detection model to obtain a first target set, and performing target detection on the regional image by using the target detection model to obtain a second target set; and determining a final detection result according to the first target set and the second target set. In the implementation process, the target detection result of the first video frame (namely the complete image) and the target detection result of the regional image are comprehensively considered, and the zooming multiple of the regional image is smaller than the zooming multiple of the complete image of the video frame, so that the condition that a remote target is detected only from the compressed complete image is effectively avoided, and the detection efficiency is improved. Therefore, the accuracy of target detection is improved.

Description

technical field [0001] The present application relates to the technical fields of image processing and image recognition, and specifically relates to a target detection method, device, electronic equipment and storage medium. Background technique [0002] Advanced Driver Assistant System (ADAS) is an active safety technology that can use artificial intelligence (AI) algorithms to perform intelligent image analysis. ADAS is often used in applications such as automatic assisted driving and unmanned vehicles. . [0003] In the research and development of ADAS, the target detection algorithm is usually used for target detection, so as to achieve the purpose of perceiving the target around the vehicle. Due to the limited computing power of the on-board chip, and the resolution of the complete image originally collected by the camera is very large, before using the target detection model to perform target detection on the complete image, the resolution of the complete image is us...
