The invention relates to the technical field of computers, in particular to a video stream transmission method and device for assisting a computer and electronic equipment. The method comprises the steps: obtaining a plurality of video streams in real time, and extracting a plurality of video frames in the plurality of video streams; performing model reasoning on the video frame to obtain a video frame detection result; drawing the video frame detection result to a corresponding video frame through a computer vision library to obtain a to-be-uploaded video frame; key frames are extracted from the video frames, and movement vectors between the key frames are calculated to obtain compensation data; and compressing the video frame to be uploaded and the compensation data, and uploading the compressed video frame to be uploaded and the compensation data to a video streaming server. According to the invention, multi-channel video streams can be processed in real time, and results can be simply displayed at the cli
