Embodiment Construction

[0020] The infrared stereo thermal imaging method of the present invention comprises the following steps:

[0021] In the first step, the infrared phase mask 1 performs wave-front coding on the infrared radiation of the observed target, and its modulation transfer function (MTF) and point spread function (PSF) change;

[0022] In the second step, the coded infrared radiation information of the observed target passes through the infrared optical system 2 and the infrared sensor 3 to obtain a coded fuzzy image;

[0023] In the third step, after the output signal of the infrared sensor 3 is converted into a digital signal mode, it is input to the signal processing system 4 in the form of a differential signal;

[0024]In the fourth step, the information processing system 4 performs image restoration and image calculation on the infrared image, and after obtaining the radiation intensity information and distance information of the observed target, outputs two channels of standard ...

Abstract

The present invention discloses an infrared stereoscopic thermal image method and system. The step of the method is that: 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 signal 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 E of the radiation within the integration time 0 . 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 targ...
