Optical mark point serial number false recognition detection method, device and equipment and storage medium

Abstract

The invention relates to the technical field of computer vision recognition, and discloses an optical mark point serial number false recognition detection method, device and equipment and a storage medium. The optical mark point serial number error recognition detection method comprises the following steps of: recognizing and detecting an optical mark point serial number; obtaining a first three-dimensional position coordinate of all optical mark points of the same part of the rigid body in the t1 moment image and a second three-dimensional position coordinate of all optical mark points of thesame part of the rigid body in the t2 moment image, and calculating and correspondingly generating a first vector dot product set at the t1 moment and a second vector dot product set at the t2 momentaccording to the three-dimensional position information; sets obtained after binarization processing is conducted on the first vector dot product and the second vector dot product are recorded as a matrix M1 and a matrix M2 respectively, According to the matrix M2 and the matrix M1, whether the optical mark points have an error standard sequence or not is judged. By detecting whether the serial numbers of the mark points correspond to errors or not, the technical problems that due to the fact that too many mark points exist in a specific part, the mark points are mistakenly recognized, calculation errors are caused, and the motion capture precision is affected are solved, and therefore the motion capture precision is improved.

Description

technical field [0001] The present invention relates to the technical field of computer vision recognition, in particular to a method, device, equipment and storage medium for misrecognition and detection of serial numbers of optical marking points. Background technique [0002] The optical motion capture system is a motion capture technology that uses high-speed cameras to capture optical markers, identify and track the trajectory of objects, and realize human-computer interaction in various environments including VR. The existing optical motion capture technology usually continuously emits high-frequency fixed-wavelength infrared signals around the installed infrared camera as the basis for spatial position tracking. [0003] However, in the actual application process, the above-mentioned motion capture technology has certain defects. Because there are too many marking points on the whole body of the optical motion capture, especially the parts with relatively dense markin...
