Abstract

The invention discloses a robot grasping pose estimation method based on an object recognition depth learning model, which relates to the technical field of computer vision. The method is based on anRGBD camera and depth learning. The method comprises the following steps: S1, camera parameter calibration and hand-eye calibration being carried out; S2, training an object detection object model; S3, establishing a three-dimensional point cloud template library of the target object; 4, identifying the types and position of each article in the area to be grasped; 5, fusing two-dimensional and three-dimensional vision information and obtaining a point cloud of a specific target object; 6, completing the pose estimation of the target object; S7: adopting an error avoidance algorithm based on sample accumulation to avoid errors; S8: Steps S4 to S7 being continuously repeated by the vision system in the process of moving the robot end toward the target object, so as to realize iterative optimization of the pose estimation of the target object. The algorithm of the invention utilizes a target detection YOLO model to carry out early-stage fast target detection, reduces the calculation amount of three-dimensional point cloud segmentation and matching, and improves the operation efficiency and accuracy.

Description

Technical field [0001] The present invention relates to the technical field of computer vision, in particular to a robot grasping pose estimation method based on an object recognition deep learning model. Background technique [0002] In recent years, with the continuous development of the computer vision field, machine vision technology has been widely used in various fields of manufacturing and service industries.
