The invention discloses a vehicle-mounted video uploading control method based on video content analysis. The method comprises the following steps: a central monitoring platform configures a time range for video uploading for a vehicle-mounted terminal, and a video uploading command is sent to the vehicle-mounted terminal; the vehicle-mounted terminal acquires video monitoring information inside and outside the vehicle in real time and the information is uploaded to the central monitoring platform for realizing video monitoring; during the video uploading process, the vehicle-mounted terminal judges whether the current time is in the configured video uploading time range in real time; if yes, the next step is carried out; if not, the data uploading channel of the vehicle-mounted terminal is closed; and the central monitoring platform analyzes the monitored video, and according to a video analysis result, data transmission control in the uploading time range is realized. Thus, according to the monitoring time configured by the central monitoring platform and the video content analysis result, vehicle-mounted video uploading control is realized, and the traffic resource utilization rate and the data transmission flexibility are improved.
