The invention provides a bridge live load optimized recognition method based on multi-source redundant information. The bridge live load optimized recognition method based on the multi-source redundant information comprises the following steps: step S1, collecting bridge structure response data generated by each monitoring sensor when a vehicle passes separately, and obtaining corresponding peak data; step S2, obtaining a video frame of a vehicle monitoring video in a traffic monitoring device when the vehicle passes each monitoring sensor and identifying, thereby obtaining relative position information of the vehicle in the video frame and the vehicle position coordinate; step S3, judging a vehicle position state formed between the current vehicle and each one of other vehicles in the video frame according to the relative position information; step S4, calculating the vehicle weight of each monitoring sensor corresponding to the vehicle according to the vehicle position state, the vehicle position coordinate
