Pose measurement device used for measuring dynamic poses

Abstract

The invention discloses a pose measurement device used for measuring dynamic poses. The device comprises a double-screen laser imaging system and a binocular vision detection system. The double-screen laser imaging system comprises a first laser receiving screen, a second laser receiving screen and a transparent-reflection prism. A diffuse reflection coating is painted on each of the first and second laser receiving screens. A 500-600nm band-pass filtering film is painted on a half-transparent face of the transparent-reflection prism. The first laser receiving screen and the second laser receiving screen are mutually perpendicular to each other and parallel to adjacent two faces of the transparent-reflection prism. The distances from the first laser receiving screen and the second laser receiving screen to the adjacent two faces of the transparent-reflection prism are not equal to each other. The binocular vision detection system comprises a first CCD camera and a second CCD camera. According to the invention, the double-screen laser imaging system receives crossed laser and carrying out imaging on the receiving screens; and the binocular vision detection system shoots the crossed laser images on the receiving screens in real time and extracts position information of each crossed laser center under an image coordinate system and the included angle between each crossed transverse line and the image coordinate system. The device is mainly used for measuring object poses in the dynamic environment.

Description

technical field [0001] The invention relates to a pose measurement system for dynamic pose measurement, which can be used for accurate real-time pose measurement of a target to be measured in a dynamic environment. Background technique [0002] Pose measurement is an important part of geometric measurement, including three-dimensional angle measurement and three-dimensional position measurement, which is widely used in precision manufacturing, aerospace, military and communication fields, among which the real-time online measurement technology of dynamic pose is getting more and more attention .
