Embodiment Construction
[0039] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
[0040] This application is applicable to the detection of video. For the detector, the more the number of network layers, the more the number of channels output by each layer, that is, the deeper and wider the network, the better the detection effect can be obtained; but the corresponding The greater the amount of parameters and calculations in the network, the slower the calculation...

The invention is suitable for the technical field of computers. Provided are a video detection method, a target detection network training method and device, and a terminal device; the video detectionmethod comprises the steps: acquiring video frame data of a target video, wherein the video frame data comprises multiple frames of first frame data and multiple frames of second frame data, at leastone second frame data is included between two adjacent first frame data; detecting the first frame data based on a trained first target detection network; and detecting the second frame data based ona trained second target detection network. According to the invention, when one video is detected, one large network and one small network are used for detecting the video frame data at the same time; compared with an existing method that only a large network is used for video detection, the method is high in detection speed, and compared with an existing method that only a small network is usedfor video detection, the method is higher in detection accuracy, so that the detection accuracy is guaranteed and the detection speed is increased when the video is detected.
Description
technical field [0001] The present application belongs to the field of computer technology, and in particular relates to a video detection method, a target detection network training method, a device and a terminal device. Background technique [0002] In recent years, with the rapid development of the Internet and the advent of the era of big data, the demand for effective data in various industries is increasing day by day. At the same time, more and more videos are uploaded to the Internet and become a new treasure trove of data. Obtaining effective data from videos for analysis is the direction of development, so video object detection has become a hot research problem. [0003] At present, target detection methods mainly include: target detection methods based on traditional image processing and target detection methods based on deep learning. The target detection method based on traditional image processing is: target feature extraction-target recognition-target posit...
