Infrared stereoscopic vision thermal image method and its system

Abstract

The present invention discloses an infrared stereoscopic thermal image method and system. The method comprises the following steps: wavefront coding of infrared radiation of observed target is made by infrared phase mask; blurred image after coding is gained when the infrared radiation signal is passed the infrared optical system and infrared sensor; output signal pass infrared sensor is input an information processing system as the forms of difference signal; the infrared image is reverted and calculated by information processing system and information of distance and radiant intensity of observed target is obtained and output. The system is setting infrared phase mask on the front end of infrared optic system, and infrared sensor which input image signal to information process system in difference signal type is set on the focus of infrared optic system. The present invention reduces the complexity degree, realizes micromation, has good real time exploration and safety capability and is suitable for apply of different situations.

Description

1. Technical field [0001] The invention belongs to infrared thermal imaging technology, in particular to an infrared stereoscopic thermal imaging method and system thereof which can simultaneously detect the radiation intensity and distance of an observed target. 2. Background technology [0002] The existing infrared imaging system can only record the intensity of the infrared radiation of the observed target within the integration time, that is, the use of the infrared radiation by the existing infrared imaging system is only limited to the average amplitude E0 of the radiation within the integration time. The information recorded and stored by the existing infrared imaging system is only the radiation intensity of the observed object within the integration time. The image information is expressed in a simple two-dimensional intensity matrix. Since the two-dimensional intensity matrix of the observed object does not contain the distance information of the observed target,...

AI Technical Summary

Problems solved by technology

The imaging system based on the above principles mainly has the following deficiencies: (i) the system is complex and difficult to miniaturize; (ii) the introduced reference radiation is easily exposed, and safety issues cannot be avoided

However, its main disadvantages include: 1. The imaging system can only work in the visible light band, and the interference of sunlight or artificial light sources in the visible light band is very obvious. More importantly, its working conditions need to meet certain lighting conditions. conditions, which limit its application and reduce the applicability

2. The imaging system cannot detect the intensity of the observed target while detecting the distance information of the observed target
