Abstract

The invention discloses a 6-degree-of-freedom visual tracking system with markers and its implementation method, wherein the 6-degree-of-freedom visual tracking system with markers includes an intelligent visual marker, a visual marker controller, and a visual tracking processor; The visual identification controller is respectively connected with the intelligent visual identification and the visual tracking processor. The invention can greatly reduce the calculation amount of image processing, thereby improving the precision of three-dimensional tracking and the response speed of the three-dimensional tracking system. The devices and technologies used are mature, reliable and easy to obtain. Therefore, the original high-cost and bulky three-dimensional visual tracking system can be improved into a mobile and embedded system.

Description

technical field [0001] The invention relates to the field of three-dimensional visual tracking of marked objects, in particular to a 6-degree-of-freedom visual tracking system for marked objects with an inertial MEMS sensor and a wireless communication network, and an algorithm for identifying and predicting the marked objects. Background technique [0002] With the development of computer and electronic technology, 3D visual tracking system is used in more and more fields. It is widely known for 3D object measurement, object motion capture, robot navigation and somatosensory manipulation. The 3D visual tracking system uses visual image sensors, imitating the visual principles of creatures, or obtains multiple images of an object in space through cameras with different poses, or obtains multiple images of an object in space on different projection planes through the same camera. Geometric optics obtains the specific spatial position and attitude of the object (hereinafter c...
