Robot automatic aiming method and system and robot

The invention provides an automatic aiming method and system for a robot and the robot, and is suitable for the technical field of robotics.The method comprises the steps that candidate armor plates are determined according to image information of an enemy robot; according to the spatial position information of each candidate armor plate relative to the candidate armor plate, the candidate armor plate closest to the candidate armor plate is determined; when the distance difference between the candidate armor plate closest to the armor plate and the target armor plate relative to the armor plate is smaller than a preset distance switching threshold value, the target armor plate is switched into the candidate armor plate closest to the armor plate; and performing Kalman filtering fusion processing on the rotation angle information of the target armor plate relative to the target armor plate to obtain target rotation angle information so as to aim at the target armor plate according to the target rotation angle
