As human society developed to the automobile as the primary means of transport, the pair of driving safety and comfort with higher standards, making the car equipped with electronic equipment and electronic systems a wider public. In the past, set in the car or car mirrors (inside rear view mirror, outside mirrors) of the initial concept, the main objective is to reduce the body the possibility of collision with the outside world, thereby increasing the service life of vehicles, which the original concept it also provides a third party in the security vehicle, to car to avoid being hit. But in fact, provided with just three mirror driving vision and message, I am afraid that the driver is also difficult to meet the demand for driving safety, especially when reversing the vehicle's rear blind spot there is great. Therefore, reversing radar began to appear. Early car parking sensor and more to the audio as a major adjunct to, installation in the vehicle from the rear bumper on the rear of the vehicle sensors to detect objects, the audio through different rhythm to remind drivers of vehicles behind the situation. Reversing radar detection range and rely on an echo to the sound of different frequencies through the tips, but apparently not just by relying on visual sound prompted more intuitive, but there are necessarily sound judgment error.After years of development, car parking sensor system has been upgraded to the techniques, improved performance, both in structure and appearance, or from the property price, now the products have different characteristics, use more of a digital display, screen display and video real-time display of these three. Among them, only by a small digital display monitor to display real-time after Paul bumper behind the obstacles and the distance. Screen display is on the increase even further over the number of vehicles, the sensor body, and then by plane images, real-time display of vehicles around the obstacles and the distance between vehicles. But such images and more for the computer drawing, and the sensor's accuracy can not be the most realistic level. So there was video real-time backup system, the reverse video surveillance system. The system allows the rear reversing the situation is more intuitive visualization, for reversing the security configuration is very practical one. Dang linked to reverse gear, the system automatically switches Wei Yu Hui rear of the HD camera head, Jiang car Hour situation clearly display on the LCD screen, and the display on the steering wheel by the rotation Dianna synthesis Dang Ian Jiao Douse Deifying the journey line, which accurately and intuitively grasp the car situation. Clearly, reversing the video surveillance system is more than a full range of parking sensor intuitive and practical.
Since then with the further development of automotive technology, people no longer content to see the car just behind the real-time image, the other blind spots, such as body side, front bumper, and when turning corners, etc., have the need to further explore. Example, in its top models such as the Lexus LX570 equipped with a blind spot monitor, the system specially designed for the traffic and urban environment design (such as garage parking, etc.), through the placement front grille and right outside mirrors under the camera, the driver just tap the button on the dashboard, you can view real-time vehicle front and right side of the screen, with the parking sensor to use, safe parking.
Automotive technology is always endless, and subsequently appeared in a full range of 360 ° panoramic surveillance system, first by the Nissan Motor Company released the world's first Around Rear View Monitor Panorama surveillance system around the device through the body high-resolution ultra-wide-angle lens and Ranging Radar, combined with the center console on the display screen, Panorama surveillance system can display real-time aerial view and the surrounding body image, to provide the driver a complete view auxiliary driving. Aerial view from the car body located in front, left and right outside rearview mirrors and rear of the four super-wide-angle cameras to offer the four cameras were collected before and after the vehicle body about the real-time images of four regions, then computer automatically synthesize a complete 360 ° panoramic images displayed on the center console, the visual effect is equivalent to the top of the car to place a camera, real-time monitoring of the actual scenery around the body. Panorama surveillance system console screen images cut to the left and right, the right side of the smaller blocks can be synthesized in the body aerial display computer screen, and left large blocks of the current gear is visible, select Show front of the vehicle or behind the real-time image.
