Uncooled thermal imaging cameras and visible light cameras (hereinafter referred to as "equipment") are mainly used for active rotorcraft equipment, which can detect and display the road conditions underneath the rotorcraft in day and night or in low visibility weather conditions such as smoke, fog, rain, and snow. The video image, assist the driver to drive the rotorcraft.
The equipment is mainly composed of infrared thermal imager, visible light camera and wiring harness (including communication line and power line). The equipment is installed at the front end of the rotorcraft to facilitate the collection of ground information. The device is connected to the integrated display with an aerial plug cable. The aerial plug cable includes DC:12V power supply for the device, serial communication RS232, and two-channel SDI video output.
The equipment can be used to identify ground routes, personnel, and equipment without any light source lighting (especially in wind, fog, rain, and snow); it can identify terrain undulations; it can smoothly guide the driver to lift the rotorcraft.
There are two options of the resolution: 640x512 and 384x288, both adapt optical 19mm fixed lens.
a) High image quality, high recognition of scenes and obstacles;
b) Waterproof performance, high reliability, and solid structure;
c) Automatic window heating and defrosting to meet the use under various bad weather;
d)The weight of the equipment is small, less than 1kg.
Structure and working principle
The working principle of the uncooled infrared thermal imaging camera is: the infrared radiation of the target object is focused to the photosensitive surface of the infrared focal plane detector through the infrared optical system. The infrared photoelectric conversion array of the detector converts the optical signal into electrical signal, and the core circuit The electrical signal is sampled by AD to obtain a digital video signal, and then processed by an image algorithm to output an infrared thermal image to the display.
The working principle of the visible light camera is: the light signal is collected by the sensor (CMOS), and the light signal is converted into an electrical signal. The movement circuit converts the electrical signal into a digital video signal, and then encodes to present an image, and then passes the image algorithm After processing, the visible light image is output to the monitor for display.
