Problems solved by technology

However, when the 3D laser ranging system is used to collect point cloud data to build a 3D model of the scene, in order to make the data more accurate and ensure the accurate description of certain details in the scene, as much point cloud data as possible needs to be collected. As dense as possible, so there is a conflicting relationship between accuracy and scan rate

Embodiment Construction

[0038] In order to verify the effectiveness of the method, the specific embodiment of the present invention comprises three aspects, the one, the data acquisition process of Kinect sensor, the 2nd, the point cloud data rasterization of Kinect sensor is obtained the rough location information of workpiece, the 3rd, according to The position information is converted to the scanning angle of the 3D laser ranging system for fine data collection.

[0039] The sensor used in this method is a Kinect sensor and a three-dimensional laser ranging system. The Kinect sensor is a somatosensory peripheral developed by Microsoft Corporation, which can obtain depth image information and visual image information. However, the best distance for the Kinect sensor to perceive the environment is 1.2 meters to 3.5 meters, and the error is at the centimeter level, but as the sensing distance increases, the error will also increase. The three-dimensional laser ranging system used in the present inve...

Abstract

The invention discloses a workpiece position-pose on-line detection method based on the cooperation of a Kinect sensor and a three-dimensional laser distance measuring system, and is applied in the technical field of sensing workpiece positions and poses through human-machine cooperation and interaction systems and industrial robots. According to the method, cooperative work between the Kinect sensor and the three-dimensional laser distance measuring system is adopted to collect data; through three parts of preprocessing on obtained point clouds, associated calibration between the Kinect sensor and the three-dimensional laser distance measuring system and the on-line detection of the Kinect sensor and the three-dimensional laser distance measuring system, the problems are solved that the point clouds of the Kinect sensor are sparse, the data accuracy is insufficient and the accuracy and scanning speed of the three-dimensional laser distance measuring system have contradictory relations; the industrial robots can more efficiently and accurately acquire the accurate size information and position-pose information of workpieces, and the accuracy and working efficiency are improved. The method can be applied in the artificial intelligence fields of the understanding of the industrial robots on the working environment and the like.

Description

technical field [0001] The invention belongs to the technical field of man-machine cooperative interaction system and industrial robot's perception of the position and posture of working objects, relates to the joint calibration and cooperative detection between Kinect sensor and three-dimensional laser ranging system, and is mainly applied to Kinect sensor and three-dimensional laser ranging system Collaborative online detection of the position and attitude of the work object.
