Dual-binocular infrared and visible light fused stereo imaging system

Abstract

The invention discloses a dual-binocular infrared and visible light fused stereo imaging system and relates to the field of binocular stereo imaging system. The system comprises a left field visible light camera and a right field visible light camera which are arranged symmetrically and align to an object to be measured to guarantee parallel optical axes and co-plane imaging planes. A left field dichroscope and a right field dichroscope are arranged symmetrically and are arranged in front of the left field visible light camera and the right field visible light camera respectively. A left field infrared camera and a right field infrared camera are arranged symmetrically and are arranged on the outsides of the left field visible light camera and the right field visible light camera respectively, and lenses face towards the left field dichroscope and the right field dichroscope respectively. By means of the system, by the design of a dual-binocular infrared and visible light image fusion technology, the defect of the single-wave-band stereo imaging system is compensated, and the problem of accuracy reduction of images obtained due to matching among systems is solved.

Description

technical field [0001] The invention belongs to the field of binocular stereoscopic imaging systems, and in particular relates to a binocular binocular infrared and visible light fusion stereoscopic imaging system. Background technique [0002] With the development of science and technology, image technology occupies an increasingly important position in information acquisition technology, and the requirements for the quality and nature of the acquired images are also getting higher and higher. In order to meet the requirements of image acquisition quality, infrared and visible light fusion technology and three-dimensional reconstruction technology came into being and have been widely used. [0003] The existing binocular stereo vision system is relatively common to be constructed by using a single-band camera. Visible light binocular stereo vision system technology is mature, but it cannot adapt to the work needs in special environments such as smog, high temperature, and ...

AI Technical Summary

Problems solved by technology

Visible light binocular stereo vision system technology is mature, but it cannot adapt to the work needs in special environments such as smog, high temperature, and darkness; although infrared band stereo vision system has imaging advantages in some special environments, the infrared image cannot reflect the measured object Texture details, low imaging contrast, low signal-to-noise ratio

Therefore, when one system is used alone, the acquired image information is single and the use environment is limited; and if two systems are used at the same time, the accuracy of the acquired image will be reduced due to the problem of coordination between the systems, and the overall cost will be increased

Image fusion technology can realize the integration of multi-band information, but the application of this technology in the field of stereo vision has not been reported
