[0002] Objects with a temperature higher than absolute zero (-273 °C) will generate infrared radiation. Infrared thermal imaging is a non-contact measurement that detects the thermal energy of an object and converts it into a thermal image of the object's temperature distribution that can be observed by humans. Especially in high-temperature and high-pressure environments, operators can stay away from the object to be measured to achieve the purpose of measuring the surface temperature of the object. At the same time, it can also detect the operating temperature of some equipment. In the case of no visible light at night, the temperature of an object and its surface can be detected through infrared radiation, and it has a very broad application prospect and is widely used in fields such as medical treatment, intelligent driving, construction, fire protection, and consumer electronics.

When collecting thermal images corresponding to different requirements, the lens cannot be replaced. At the same time, the ISP module and the output interface are both integrated into the internal control circuit board, the magnitude of the ISP module cannot be increased, and the single output interface is limited in connecting to the client.
