The invention discloses a multi-vision based both-arm robot hand-eye coordination method, and belongs to the field of robot vision. Two multi-vision cameras are used for target positioning, a mechanical arm close to a target object is selected for grabbing, meanwhile, the target object can be positioned again, and the target object is grabbed to be fed to a fixed zone. According to the multi-vision based both-arm robot hand-eye coordination method, the problem that in the existing scheme, only one camera in binocular cameras shoot the object, and consequently the binocular distance measurement and positioning cannot be achieved is solved, and the accuracy of target object grabbing by the mechanical arm is improved.
