This invention relates to the field of robot control technology, specifically disclosing a vision-gimbal coordinated laser pointing device and control method for a quadruped robot. The device includes a depth camera mounted on the robot's head, a two-dimensional gimbal on its back, and a control module. The depth camera acquires the target's three-dimensional coordinates. The two-dimensional gimbal consists of a yaw servo and a pitch servo, with a laser mounted at its end. The control module calculates the target's yaw and pitch angles in real time based on a pre-calibrated rigid body transformation relationship between the camera and gimbal coordinate systems, driving the gimbal to move and precisely point the laser beam at the target. This method achieves closed-loop control through "detection-coordinate transformation-angle calculation-servo control." The system incorporates a dynamic compensation mechanism that continuously corrects the gimbal angle during the quadruped robot's movement, stably tracking the target and effectively overcoming pointing deviations caused by robot vibration, significantly improving pointing accuracy and reliability in dynamic scenarios such as inspection and security.

The invention discloses a self-service convenient vision detection device, which is characterized in that an electronic visual chart is provided with a switchable vision detection mark, and the electronic visual chart is also provided with an induction operation handle and an inductor for shielding the position of glasses; an operator information confirmation module and an up-down left-right confirmation key are arranged on the operating handle, the shielding glasses comprise a glasses frame and two adjustable shielding pieces, and the two adjustable shielding pieces are correspondingly arranged in a left glasses frame and a right glasses frame of the glasses frame in an angle-adjustable mode and used for adjusting whether the glasses frames are shielded or not. The method has the advantages that quick connection is realized through pairing without waiting; the distance is measured through the sensor, and the eyes are shielded through the shielding glasses.
