Abstract

The invention provides a robot pose calculation method and a pose calculation device. The method comprises the following steps: acquiring a three-dimensional CAD model of an object to be recognized; sequentially sampling images from the bottom layer to the highest layer of an image pyramid corresponding to the three-dimensional CAD model in the pose range, and combining the images with the similarity exceeding a threshold value to establish a layered view; projecting each view of each layer in the layered view to generate a two-dimensional matching template; matching an image pyramid corresponding to an image shot by the virtual camera with a two-dimensional matching template to obtain a two-dimensional matching pose; and calculating the three-dimensional pose of the object according to the parameters of the virtual camera and the two-dimensional matching pose, and obtaining then the three-dimensional pose of the robot. According to the method, the CAD model of the object to be recognized is matched with the image shot by the virtual camera, so that the purpose of reliably recognizing the three-dimensional pose of the object according to a single image is achieved, and the three-dimensional pose of the object can be accurately obtained.

Description

technical field [0001] The present invention relates to the technical field of intelligent robots, in particular to a robot pose calculation method, a robot pose calculation device, a robot and a non-transitory computer-readable storage medium. Background technique [0002] Determining the pose of three-dimensional objects is used in many industrial situations, such as the grasping of industrial manipulators. In the face of the increasing application of machine vision technology in industrial and medical manipulators, a stable three-dimensional object recognition position is required. Attitude calculation method. [0003] In related technologies, generally multiple images are obtained by a camera, and after obtaining the coordinates of the object in the camera coordinate system according to the multiple images, the three-dimensional pose of the object is obtained after performing multiple coordinate transformations. This method requires multiple images, which increases the ...
