Whether it is the panoramic image system or the ADAS, it will undoubtedly bring the better experience to the driver and enhance the safety of the car. The panoramic image system still faces challenges in image splicing, video processing, etc. We finally return here to the basic car The camera comes to the current core technical barriers.Vehicle video recorder manufacturer
The night vision function will become one of the core barriers to car cameras. According to the statistics of the National Highway Traffic Safety Administration (NHTS), even though night driving only accounts for a quarter of the total road traffic, half of the incidents occurred. The accident caused by poor sight at night accounted for 70%. Therefore, the car camera must be required to have a strong photosensitivity, so that it can work normally throughout the day, that is, a wide spectral range of near-infrared (from 400nm - 1100nm), the future night vision function will become standard with the car camera.
There are three types of night vision technology that have been put into use: low-light night vision technology, passive infrared night vision technology, and active infrared night vision technology. The low light uses the low-brightness natural light reflected by the night-time target and enhances it up to several hundred thousand times so as to achieve an image suitable for the naked eye to observe at night. Passive infrared night vision technology is adopted.Mobile Car Dvr Recorder 1080p
Infrared radiation sources with background and background radiation are used for imaging. Compared with low-light and active infrared technologies, no extra light source is needed, and the detection distance is the longest, the accuracy is high, but the imaging is also the most blurred, and the screen recognition is low. Active infrared technology, also known as near-infrared night vision technology, uses infra-red searchlights to emit invisible light to illuminate the target and uses reflected light for imaging. The visual distance is moderate and the imaging is clear.
Compared with passive night vision technology, active night vision technology imaging is more clear, and can directly use image recognition to detect night road signs and pedestrians, so active night vision technology is more in line with the application scenarios in the automotive field. At the same time, passive infrared night-vision technology is much more costly than active infrared night-vision technology because the infrared infrared focal plane imaging material and technology of the passive infrared night vision system are embargoed.Vehicle tracking system supplier
The core laser night vision technology requires comprehensive near-infrared and medium-range laser night vision imaging and processing technologies to solve technical problems such as all-weather imaging, two-way high-speed moving high-speed focusing, eliminating laser speckle, and the need for zoom technology with vehicle speed synchronization. And flashlight effect, technical difficulties, therefore, the night vision function will become one of the automotive camera core barriers.
