Car Rear View System - New Automotive Safety Field

Rear-view system is thoroughly subverted

For the traditional optical rearview mirror defects, the professionals have innovated and optimized using different techniques from different angles. According to existing products on the market, including radar/rear view camera/distance logo/infrared night vision and so on, from a degree of sense, which is a thoroughly subversion of rear view system.

Reversing radar technology

The system or apparatus made using radar (laser, ultrasound) ranging principle have been widely used in the automobiles. It can accurately measure the distance between the wave source and the obstacle, informing the driver of obstacles around by sound or a more intuitive display. It solves the trouble of driver when parking and starting the vehicle, which helps the driver wipe out the vision of dead ends and blurred vision defects, improving the safety of driving. The reversing radar system has undergone six generations of technological improvements; the six generations of products have different features either from structural appearance or from performance price. Currently digital display, screen display and magic mirror reversing radar are mostly used.

Video monitoring technology (automotive rear view system)

Visual monitoring system is to install camera at the top of the trunk lid or license plate, and pass the shot pictures to the screen (usually liquid crystal display) in front of the driver's seat, the driver will be able to know the situation after the car by only looking the display in front of him. It can be divided into two modes: wired form of link cameras and displays and wireless rear view system: using 2.4G wireless video technology, transmitting the camera signal to the display by wirelessly method. This technology has solved the reverse, night vision and other problems. The car rear view system uses two kinds of CCD or CMOS imaging technology like other video surveillance technology. Due to the special imaging of car rearview system, CMOS guarantees quality image and quality, which has accounted for most of the market with lower cost; in addition, the wireless transmission makes the system installation to be easier.

Infrared night vision technology

It is the night vision technology to implement observe by initiative infrared lamp irradiation and target reflectance infrared source. Currently, the infrared lamp used in the monitoring field is mainly semiconductor solid-state light-emitting IR (infrared light-emitting diode) lights, its biggest advantage is completely free of red storm points and long life. Infrared night vision technology mainly matches with the application of visual surveillance technology, which can make the cameras to improve night driving vision by using infrared ray.

Automotive rear-view system can achieve visual imaging

Compared to reversing radar system, car rear view system has the advantage of accurately judging distance, this is because the gutter, cliff, protruding rebar, bamboo poles and other ultrasonic sensor in the rear of the car are insensible, which is the dead ends of reversing radar system in reversing safety. Now the car audiovisual systems become more and more perfect, automotive rear-view system can achieve visual imaging by integrating radar, infrared night vision and even with the GPS display.
