Traffic safety recorder is to record and cyclically update the road surface conditions in front of or around the car through digital video recording. The information such as car recording, car acceleration, steering and braking will be recorded. It is used to restore the accident and supervise the driver's driving. Time, avoid fatigue driving, conduct safety monitoring, and provide clues for car theft.
Car safety recorders are mandatory installations in many countries, but they are installed independently in China. In fact, installing safety recorders on their cars is a good thing.
Car safety recorders belong to automotive electronics products. Faced with the promotion and promotion of various brands on the market, there is no lack of excessive publicity and misleading consumers, which makes it difficult for car owners to purchase. Today, Xiaobian is popular for everyone. The basic knowledge of car safety recorders provides guidance for further purchase.
First, it is best to choose a full-glass lens recorder. The transparency and sensitivity of the lens determine its ability to capture images in dark light. Driving recorders mostly use three types of lenses: all-glass lenses, resin lenses, and glass resin hybrid lenses. Compared to other lens materials, glass has the best light transmittance and is the most sensitive. Therefore, a lens made of all glass can achieve better shooting results at night. Moreover, the glass lens is not easily deformed at high temperatures and low temperatures, and has more adaptability and higher security.
Second, purchase high-definition, high-definition driving recorders, owners of high-definition video recording requirements for driving recorders, you can choose a product with a video resolution of 1920*1080P, record video on the driving recorder. Sharpness requires the average owner, you can choose a video resolution of 1920 * 1080P products.
Third, it is not that the wide angle is the bigger the better, and ensuring that the wide angle of the driving recorder is to ensure driving safety and reduce the basic requirements of visual blind spots. However, it should be noted that the wrong concept of change is that although wide-angle can reduce the blind area, it is not necessarily the bigger the better! The larger the wide angle, the more severe the distortion of the picture, the distortion and deviation in the distance and angle of the picture, and the decrease of the resolution of the entire image. Therefore, consumers should pay attention to confirming whether they really achieved the wide-angle data declared in the advertisement when purchasing a driving recorder.
Non-contact measurement methods are mainly divided into two categories.
One is a passive method, that is, does not require a specific light source, depends entirely on the natural light conditions of the object to scan, often using binocular technology, but the accuracy is low, only objects with geometric features can be scanned, can not meet the requirements of many fields .
The other is the active method, which is to project a specific light to the object, which represents the technical laser line scan, the accuracy is relatively high, but because only one light can be projected at a time, the scanning speed is slow. In addition, because lasers can cause harm to living organisms and more precious objects, they cannot be used in certain areas.
The emerging technology is structured light scanning. Structured light is also an active method. By projecting or rastering multiple light rays at the same time, one surface of the object can be taken. Only a few surfaces are needed to complete the scan. Yes

Scanning speed is fast and programmable.
There is also a low frequency pulse wave (low frequency sound wave) type principle, which is mainly used for level measurement. The low-frequency pulses are transmitted based on the two-dimensional array beamformer and the 3D level scanner receives echoes from the silo, bin, or other chamber material. The digital signal processor of the device samples and analyzes the received signal. By estimating the time and direction of arrival of the echo, the processor forms a three-dimensional map of the surface of the material. This image is processed by a proprietary calculation method. And generate 3D images, which can be displayed on the remote screen. The level gauge can accurately calculate the volume and quality of materials according to this, enough to make the process level monitoring and inventory control reach a new height. Accurate material inspection of level gauges can improve operational efficiency and management capabilities, reduce the high cost of unexpected situations, and accelerate revenue returns.
