Multi-sensor fused three-dimensional temperature measuring device

Abstract

The invention provides a multi-sensor fused three-dimensional temperature measuring device which comprises a data collector and a black body. The data collector comprises a shell, a visible light lens module, a thermal infrared imager and a three-dimensional laser radar are fixedly arranged in the shell, and the visual axis directions of the visible light lens module, the thermal infrared imager and the three-dimensional laser radar are consistent; the black body is a programmed black body and comprises a control box, a black body surface and heat dissipation fins, and the black body surface is opposite to the working surface of the shell at an interval. According to the multi-sensor fused three-dimensional temperature measuring device provided by the invention, image, temperature distribution and point cloud distribution data can be acquired at the same time, and the data can be transmitted to an upper computer; in addition, through combination of the thermal imager and the program control black body, real-time calibration is periodically carried out, and high-precision temperature measurement of the non-refrigeration thermal imager at various environment temperatures is realized.

Description

Technical field [0001] The present invention relates to engineering infrared camouflage techniques, and more particularly to three-dimensional temperature measurement techniques, and is specifically a three-dimensional temperature-fused 3-dimensional temperature-fused device. Background technique [0002] Since the 1980s, hot infrared camouflage is the focus and difficulties of research in the field of camouflage. In order to assess the effectiveness of infrared camouflage technology, a set of effective measuring devices quickly obtain the exposure of the camouflage in temperature and image to better guide the infrared camouflage design. [0003] The thermal infrared imaging acts as a non-contact, graphical temperature measurement technology, can obtain two-dimensional plane temperature of the object, due to a single view, lack of three-dimensional information, conventional thermal imager temperature mode does not adapt to infrared camouflage three-dimensional temperature analysi...

AI Technical Summary

Problems solved by technology

[0003] As a non-contact and graphical temperature measurement technology, thermal infrared imaging can obtain the two-dimensional plane temperature of the object. Due to the single viewing angle and lack of three-dimensional information, the traditional thermal imager temperature measurement method cannot adapt to infrared camouflage three-dimensional temperature analysis and The need for visualization; in addition, to achieve high-precision temperature measurement, it is necessary to choose a cooling-type thermal imaging camera with a high cost, which is not conducive to large-scale measurement experiments
