The difference between starlight night vision and blind night vision in panorama camera

The differences between them are as follows:

Compared with starlight night vision, the night vision driving recorder for the blind can shoot full-color pictures in dark environment through special processing technology, and the brightness range that human eyes can distinguish is about 200~20000cd/㎡, and the night vision recorder for the blind can record to 150.

What is the effect of CD/m2 fluorescence and night vision? In the test, in the dark night, the lenses of other driving recorders are dark, and the night vision recorder for the blind can also record full-color videos normally.

The low illumination effect of early driving recorder is average. With the improvement of image sensor technology and the application of image denoising algorithm, the low illumination effect of driving recorder has been improved. It can obtain real-time video images in dim light with the help of surrounding light sources, such as street lamps and corridor lights, but its application scope is not as wide as that of infrared cameras, so it is generally used in ordinary driving recorders, which can only barely meet the needs of shooting in good lighting conditions at night.

If you want to know the principle of night vision, you must know something about the principle of light. The energy of light wave is related to its wavelength: the shorter the wavelength, the higher the energy. Among visible light, violet light has the highest energy and red light has the lowest energy. Adjacent to the visible spectrum is the infrared spectrum. Infrared rays are divided into three categories:

Near infrared —— Near infrared is adjacent to visible light, and its wavelength range is 0.7- 1.3 micron (1 micron equals one millionth of a meter).

Mid-IR-Mid-IR wavelength range is 1.3-3 microns. Near infrared and mid infrared are applied to various electronic devices, such as remote controllers.

Thermal IR)- Thermal IR occupies the largest part of the infrared spectrum, and its wavelength range is 3-30 microns.

The main difference between thermal infrared rays and the other two infrared rays is that thermal infrared rays are emitted from objects rather than reflected from them. An object can emit infrared rays because its atoms have changed in some way.
