The invention belongs to the technical field of brain-computer interfaces, and particularly relates to a multi-brain collaborative brain-computer interface system and a video target detection method based on the system, and the system comprises a stimulation presentation module, a synchronous acquisition module, a data preprocessing module and a classification model module. The stimulation presentation module is used for synchronously presenting video stimulation to a plurality of subjects, the synchronous acquisition module is used for synchronously acquiring electroencephalogram signals of the subjects, and the data preprocessing module is used for preprocessing the acquired electroencephalogram signals; and the classification model module is used for processing and identifying the collected electroencephalogram signals by adopting a cross-domain network based on mutual learning. According to the invention, pseudo labels generated by collaborative decision are fed back to individual networks in the mutual l
