The invention relates to a bionic compound-eye square array image sensor system, which is characterized in that a video camera consists of a first camera, a second camera, a third camera and a fourth camera which are arrayed symmetrically as a square to form a video camera array; the four cameras are separately installed at the positions of the four corners on surface A of the camera array and the four connectors of camera circuits are separately corresponding to the four cameras on surface B; the four cameras are separately connected with four video coders with video joints. The invention has the advantages that by forming a bionic compound-eye image sensor system with four cameras, the invention could produce two groups of matched images, i.e. an image matched with a direct-coupled system and an image matched with a cross-coupled system; the matched images amount to six pairs; in this way, the tri-dimensional structure of objects in the images could be effectively acquired, and with the matched image algorithm, the tri-dimensional information of objects in the images could be acquired dynamically with automatic correction.
