Embodiment Construction

[0030] Such as figure 1 As shown, in this embodiment, a vehicle-mounted low-temperature infrared detection system includes a central control unit, an infrared detection unit, an amplification and comparison unit, and an output display unit;

[0031] The central control unit converts the detected signal into a video signal for output and display;

[0032] The infrared detection unit includes an infrared temperature difference thermopile and a thermistor, and obtains a temperature signal through the thermopile;

[0033] The amplifying and comparing unit amplifies the detected temperature signal and compares it with the thermistor powered by constant current;

[0034] The output display unit converts the signal into an image and displays it.

[0035] In a further embodiment, the central control unit includes an MCU control chip and an A / D converter, through which the A / D converter performs analog-to-digital conversion into digital signals, and the MCU control chip performs data...

Abstract

The invention discloses a vehicle-mounted low-temperature infrared detection system. The system comprises a central control unit, an infrared detection unit, an amplification comparison unit and an output display unit, wherein the central control unit converts detected signals into video signals and outputs and displays the video signals, the infrared detection unit comprises an infrared temperature difference thermopile and a thermistor, a temperature signal is obtained through the thermopile, the amplification comparison unit is used for amplifying the detected temperature signal and comparing the amplified temperature signal with a constant-current power supply thermistor, and the output display unit converts the signal into an image and displays the image. The vehicle-mounted infrareddetection system is advantaged in that detection of the vehicle-mounted infrared detection system on a low-temperature object is improved, when external visibility is low, naked eye observation is notfacilitated, when the external environment is detected through infrared, detection on the low-temperature object is enhanced so as to prevent a low-temperature obstacle from influencing driving.

Description

technical field [0001] The invention relates to vehicle-mounted low-temperature infrared detection and belongs to the field of infrared detection. Background technique [0002] With the development of autonomous driving technology, vehicle-mounted infrared detection has gradually become a recent craze. The most basic requirement for autonomous driving vehicles (or with ADAS functions) is to be able to "see" all objects and surrounding environments as early as possible under all conditions, and at the same time provide information for decision-making. Provide adequate reaction time. [0003] The current visible light cameras cannot meet such needs (although many camera CMOS sensors have added near-infrared functions, which can solve the problem in hazy lighting conditions, but cannot cope with dark conditions). [0004] In order to solve this problem, one of the current mainstream solutions is the fusion solution of visible light camera, millimeter-wave radar, and lidar, but...
