The invention relates to a method and device for detecting a posting behavior based on a video, computer equipment and a computer readable storage medium, and the method comprises the steps: detecting image blocks in a posting behavior detection region, and screening out the image blocks with a preset change event from the image blocks as target detection small blocks; wherein the image blocks are a plurality of image areas obtained by dividing the current video picture, and one image area is used as one image block; and determining whether a target posting behavior exists in the posting behavior detection area or not based on data of the target detection small block in the video frame before and after the preset change event of the target detection small block. According to the method, whether the target posting behavior exists or not is judged only by analyzing the data where the target detection small blocks are located, the target posting behavior is effectively analyzed with less data, and consumption of target posting behavior detection algorithm resources is effectively reduced.
Description
technical field [0001] The present application relates to the field of data analysis and processing, and in particular to a method, device, computer equipment and computer-readable storage medium for video-based detection of posting behavior. Background technique [0002] With the continuous evolution of video security technology, traditional video surveillance technology is gradually becoming intelligent, and it can solve social problems more deeply and promote the harmonious development of society. The behavior of posting advertisements, posters, stickers, etc. has always been a thorny social issue in urban development. How to better solve these problems has always been the development direction of security monitoring technology. [0003] In the prior art, the trip wire intrusion or area intrusion event is judged first, and then the posting algorithm is used to detect and analyze the entire video frame data before and after the event to determine whether there is a target...
