Monocular vision measurement cooperative target visual simulation system

Abstract

The invention relates to a monocular vision measurement cooperative target visual simulation system, which comprises a cooperative target model loading module, a background model loading module, a visual rendering module, a motion model loading module, a man-machine interaction module and the like, and is characterized in that the cooperative target model loading module is used for loading a cooperative target model file; the background model loading module is used for loading a background model into a system memory; the visual rendering module is used for setting a view field size, a viewpoint position and a viewpoint direction according to camera parameters and a camera position input by the man-machine interaction module, drawing a cooperative target three-dimensional graph, displayinga background texture picture, setting global environment illumination and simulating active illumination; and the motion model loading module is used for drawing a cooperative target three-dimensionalgraph of a corresponding visual angle. Closed-loop simulation verification can be quickly completed in an algorithm design stage only by importing a cooperative target model file without a real object, and meanwhile, a real value of a target in a camera coordinate system can be provided for verifying the measurement precision of the algorithm.

Description

technical field [0001] The invention relates to the technical field of scene simulation, in particular to a scene simulation system for a monocular vision measurement cooperation target. Background technique [0002] Optical vision measurement technology is an emerging measurement technology based on optoelectronic technology and machine vision technology. It is recognized as the most promising three-dimensional measurement method due to its advantages of high sensitivity, high speed, non-contact, and non-damage. There are many methods of optical vision measurement, among which the monocular vision measurement method based on cooperative targets is widely used in the fields of aviation, aerospace, industry and manufacturing because of its high reliability and high precision. [0003] The monocular vision measurement system based on the cooperative target uses a monocular camera to measure the pose of the target with artificially shaped marking features. In the past, this ki...
