Single-eye vision semi-matter simulating system and method

Abstract

Said system of the present invention includes virtual imaging unit, picture projection unit and video camera realizing unit. In semi practicality emulation, said method includes: in virtual imaging unit, constructing and configuring virtual scene position stance through OpenGL etc software, through virtual video camera projecting virtual scene to computer screen, then picture projection unit projecting picture to projection plane, through video camera realizing unit to obtain projected picture on projection plane, finally through computer software to calculate virtual video camera inner parameter, virtual scene position stance; through comparing with set value and analysing to obtain emulation result accuracy error. Said invention has advantages of Said invention has advantages of simple equipment, easy realizing, and wide use range, especially suitable for realizing calibrating and vision guided navigation positional emulation.

Description

technical field

[0001] The invention relates to a monocular vision semi-physical simulation system and method. Background technique

[0002] With the development of computer vision theory and computer technology, computer vision has been widely used in target recognition, visual guidance, industrial measurement, industrial control, etc. Hardware-in-the-loop simulation technology is also called hardware-in-the-loop simulation. When conditions permit, physical objects are inserted into the simulation system as much as possible to replace the corresponding part of the mathematical model, which is closer to the actual situation and thus more accurate information can be obtained. In the process of computer vision research, some complex situations are often encountered. For example, a large number of scene images are often required for algorithm research, but usually the scene conditions are complicated, and it is difficult to conduct physical experiments in the early stage of res...
