Correction method and device for mechanical arm motion

Abstract

The invention discloses a correction method and device for mechanical arm motion. The method comprises the steps that a target image of a to-be-grabbed object grabbed by a mechanical arm is acquired,the mechanical arm comprises multiple motion arms and a base, the target image comprises multiple target identifiers, and the target identifiers are arranged on the multiple motion arms, the base andthe to-be-grabbed object; the target identifiers are extracted from the target image; according to the target identifiers and the target image, the current pose information of each motion arm is determined; and according to the current pose information of each motion arm, current mechanical arm motion is correspondingly corrected. Due to the fact that in the scheme, the target identifiers are arranged on the multiple motion arms, the base and the to-be-grabbed object in advance, and the pose information of each motion arm is determined according to the target identifiers in the target image, mechanical arm motion can be corrected in a targeted manner according to the pose information of each motion arm, and therefore the technical problems that in existing methods, the cost for correctingmechanical arm motion is high and efficiency is low are solved.

Description

technical field [0001] The invention relates to the technical field of mechanical arm motion control, in particular to a method and device for correcting the motion of a mechanical arm. Background technique [0002] With the development of related technologies such as automation and intelligence, the application of robotic arms in industrial production and daily life is becoming more and more widespread. At the same time, with the improvement of people's production level and living standard, people's requirements for the precision of robotic arms are also getting higher and higher. [0003] At present, in order to improve the accuracy of the manipulator and reduce the error during the movement of the manipulator, most of the existing methods use high-precision equipment to collect the relative position data between the execution terminal of the manipulator and the object to be grasped, and then according to the The motion path is replanned based on the relative position dat...
