Double-spectrum night vision instrument vehicle-mounted system and double-spectrum fusion design method

Abstract

The invention discloses a double-spectrum night vision instrument vehicle-mounted system and a double-spectrum fusion design method. The system comprises an infrared double-spectrum imaging die set used for imaging of a visible spectrum and an infrared spectrum and for collection, processing, fusion and transmission of the image data, an image receiving system used for completing the receiving of the image data, a display terminal used for displaying the images for an observer, and a control terminal used for controlling the function and on-off of an imaging mode. Due to the adoption of the system and the method, the problem that coaxial imaging of the double spectrum image is slight bad is solved, the machining precision requirement of the imaging system is reduced, more clear images are provided for forward observation for a train; a fusion method based on a scene moving object provides a reference source for the double-spectrum imaging system, the computation load is reduced, the registering reliability is improved, the imaging on the hardware is convenient, and the real-time performance is possessed; a weight fusion method based on multi-scale bilateral filtering is simple and feasible, improves the imaging detail information and reduces the calculation ability.

Description

technical field [0001] The invention belongs to the technical field of train front vision, and in particular relates to a vehicle-mounted system of a dual-spectrum night vision device and a dual-spectrum fusion design method. Background technique [0002] The night vision device is a technology transferred from the tank night vision device, and it is a typical military technology converted to civilian use. With the rapid development of trains and high-speed rail transit and the increasing awareness of security, people have higher and higher requirements for train safety technology. The disadvantages of short distance and poor effect have become one of the potential safety hazards of train running. [0003] The existing train forward-looking observation system uses CCD or CMOS imaging system to assist observation, but this single spectral image cannot reflect the road conditions at all in bad weather, especially in fog, snow and rainy days.
