Embodiment 1

[0072] figure 1 It shows a schematic flowchart of a method for evaluating a handle tracking effect provided by the first embodiment of the present invention.

[0073] The handle tracking effect evaluation method is applied to a VR simulation system. The VR simulation system includes a handle and a camera generated by simulation. Both the handle and the camera are generated by simulation and are not physical devices.

[0074] The handle tracking effect evaluation method includes the following steps:

[0075] In step S110, the initial pose information of the handle in the world coordinate system is generated.

[0076] Specifically, the initial pose information of the handle in the world coordinate system is generated by the VR simulation system through a program according to certain rules.

[0077] For example, within the field of view of the camera generated by the simulation, the camera is set in the corresponding planes of different depth intervals, and the camera selects a...

Abstract

The invention discloses a method for evaluating the tracking effect of a handle. The method includes: generating initial pose information of the handle in a world coordinate system; first pose information; convert the first pose information of each target point into pixel information of the image coordinate system according to the mapping parameters and distortion parameters of the camera; use the visible target points in the field of view of the camera as effective target points, Using the pixel information corresponding to the effective target point as effective pixel information; calculating the second pose information of the handle in the world coordinate system according to the effective pixel information and the position information of the camera; using the initial pose information and the second pose information to determine the evaluation result of the handle tracking effect. The technical scheme of the invention can conduct preliminary verification on the design of the handle without the need of physical evaluation on all designs, and the verification period is short, fast and low in cost.

Description

technical field [0001] The present invention relates to the technical field of virtual reality, in particular to a handle tracking effect evaluation method. Background technique [0002] With the rapid development of science and technology, virtual reality technology has been recognized by more and more people. Users can experience the most realistic feelings in the virtual reality world. The authenticity of the simulated environment is difficult to distinguish from the real world, which makes people There is a feeling of being there. [0003] In the handle tracking technology in the vision-based VR simulation system, it is necessary to use the characteristics of the handle in the camera to detect the handle, so as to realize the multi-degree-of-freedom tracking of the handle. The handle's structural shape, surface luminous feature points, reflective feature points or feature patterns and other appearance characteristics determine the imaging characteristics of the handle i...
