Infrared thermal imaging automobile driving assistant system

What is Infrared thermal imaging automobile driving assistant system

Based on the infrared thermal imaging technology, the infrared thermal imaging automobile driving assistant system converts the thermal imaging contents within the field of view into 2D images, and display them via the display. 

It can effectively eliminate strong light stimulation from the vehicle in the opposite direction , and interference caused by glare in the opposite on the sight, without any effect on the field of view. It helps drivers, in the dark, and especially under such severe weather conditions as rain, snow, fog and haze, and sand and dust, clearly observe vehicles, pedestrians, and obstructions, etc., onthe road; thus, safety of the driver, passenger, and the third party can be greatly improved. 

This system can automatically identify pedestriansand vehicles in front of the automobile, mark the target position with a rectangular frame in the infrared thermal image, and, at the sam e time,judge the possible collision risk in a real time manner, and give awarning prompt to the driver.

The infrared thermal imaging automobile driving assistant system can greatly improve the environmental perception ability of drivers, significantly i mprove the driving safety factor and driving experience ofdrivers, and effectively safeguard personal and property safety of drivers.

Operating principle of infrared thermal imager
The infrared thermal imager detects infrared energy (heat) through a non-contacting way, converts it to electric signal and generates a thermal image on the display screen. The infrared thermal imager is an inspection device which can be used to calculate the temperature. It can precisely quantize and measure the detected heat, so that you can observe the thermal image and accurately identify and analyze the failure area with heat.

What is an infrared thermal imaging automobile driving assistant system?
 The infrared thermal imaging automobile driving assistant system is developed from the night-vision device of tank. In 1950s, to improve the nighttime mobility of tank, equipment with night-vision capacity was installed on the tank to make the tank move freely at night.

The infrared thermal imaging automobile driving assistant system has an infrared detection capacity and can sense infrared rays out of the range of human vision. The vehicle-mounted infrared night-vision system is widely used. Sine the price was too high, it was mainly for military use such as tank, armored carrier and radar vehicle. However, with the scientific and technological progress, market popularity and lower and lower price, common people may own the vehicle-mounted infrared night-vision system.   

Why to use an infrared thermal imaging automobile driving assistant system?
During driving at night, the road condition is clear in the area before the vehicle illuminated by the headlights on full beam. However, risks exist in the dark area ahead

Although automobile lighting technology has been improved a lot in recent years, risks of driving at night are higher than that of driving in daytime. The following situation is common: when you discover from the light that someone is exchanging tyres at the roadside or pedestrians or animals are being across the road, it is too late to take measures. 

General Motors Corporation made a questionnaire survey from drivers and made them grade thirty-to-forty electronic devices on automobile based on their degree of preference. The survey result shows that most drivers have eyes only for the automobile night-vision system and wish to install the system on their automobiles. 

 This is because the airbag and ABS can work only in case of emergency of automobile but the automobile night-vision system is an active safety device and it can discover the accident symptom in advance to nip in the bud and improve safety of automobile in special weather.

 As per statistics of NHTSA, although night driving only accounts for 25% of the total road traffic, the number of fatal accidents accounts for 50%.In addition, the number of accidents due to poor vision at night accounts for 70% (data of 2002). However, if you own a vehicle-mounted infrared night-vision system, it is like that you get eyes of owl with a telescope. The vehicle-mounted infrared night-vision system will help you to see the scene out of the illumination range of headlamp, so you can discover risks in darkness timely and improve the driving safety greatly.

On the display screen, the road edge, mark line in the middle of road, objects on the road and pedestrians at the roadside who are going across the road will be displayed. Therefore, the vehicle-mounted infrared night-vision system can discover more objects than the headlamp and can hold a panoramic view of objects within the distance two times the illumination distance of headlights on full beam.
     
The largest beneficiaries of infrared night-vision system are automobile drivers at night. Due to expansion of safety distance, they have more time to brake and respond. The vehicle-mounted infrared night-vision system cannot replace your eyes to obtain visual information. It is only used for providing information on road condition in a longer distance in bad weather, specially providing help when you cannot see clearly.

Vehicles to which the vehicle-mounted infrared night-vision system is applicable
 Passenger cars, commercial trucks, buses and fun vehicles: the infrared thermal imaging automobile driving assistant system can discover risks in advance, reduce the accident occurrence probability and ensure life safety, property safety and personal safety.Ambulances: high speed and poor braking distance of ambulances make the accident occurrence probability increase. At a high speed, the infrared thermal imaging automobile driving assistant system can also detect risks front of vehicles.

Passenger trains and freight trains: the infrared thermal imaging automobile driving assistant system can detect obstacles on the railway in a long distance in complete darkness.

Heavy engineering vehicles: for navigation of heavy engineering vehicles, the infrared thermal imaging automobile driving assistant system can improve the sensing capacity of drivers when the camera generating images based on eyesight and sunlight is failed. The infrared thermal imaging automobile driving assistant system can generate clear images penetrating dust and smog and ensure safety of pedestrians and vehicles.
