Thermal imager application Vehicle-mounted infrared thermal imaging night vision device
Data from around the world show that 60% of traffic accidents occur at night and in bad weather, mainly due to poor vision while driving. Especially when driving on roads with no street lights and severe smog at night, limited by the irradiation distance of car headlights, there will be safety hazards in driving.
Using thermal imaging cameras as a visual assisted driving system, the driver can clearly observe the information in front of the vehicle in low visibility or in the dark, and can also see areas that cannot be illuminated by car headlights, pedestrians and vehicles in the shadow of strong light. The irradiation distance of general car headlights is about 100m, while the infrared thermal imaging camera can see the unexpected road condition information of 450m.
At present, more and more automobile manufacturers have begun to develop and use the vehicle-mounted night vision system with infrared thermal imaging cameras as the core. Due to the price, major domestic and foreign automobile manufacturers only use vehicle-mounted thermal imaging cameras in their luxury models. In the near future, with the development of technology and the reduction of production costs of infrared thermal imaging cameras, vehicle-mounted night vision systems will be fully popularized.
The above is that the vehicle-mounted infrared night vision device provides drivers with clearly visible infrared night vision images, which greatly improves the safety of night driving. The vehicle-mounted infrared thermal imager can clearly see people, animals and objects in harsh environments such as total darkness, smog, dust, rain and snow, and the effective distance at night is three times that of lights. The thermal imager probe can be installed at the front end of the air inlet. It is a built-in design. It has functions such as glare removal, fog breaking, driving deviation reminder, pedestrian reminder, and driving recorder. It is small in size, light in weight, and easy to install. Features, can be installed on a variety of models.
The basic principle of night vision goggles
To understand the principle of night vision devices, you must understand the principle of light. The energy of a light wave is related to its wavelength: the shorter the wavelength, the higher the energy. Among visible light, violet light has the highest energy, while red light has the lowest energy. Adjacent to the visible light spectrum is the infrared spectrum. Infrared rays are divided into three categories:
Near Infrared (Near IR) - Near infrared is adjacent to visible light and has a wavelength range of 0.7-1.3 microns (1 micron equals one millionth of a meter).
Mid-Infrared (Mid-IR) – The wavelength range of mid-infrared is 1.3-3 microns. Near-infrared rays and mid-infrared rays are used in various electronic devices such as remote controls.
Thermal Infrared (Thermal IR) - Thermal IR occupies the largest portion of the infrared spectrum, with wavelengths in the 3-30 micron range.
The main difference between thermal infrared and the other two is that thermal infrared is emitted by objects rather than reflected from them. Objects are able to emit infrared light because of certain changes in their atoms.
