Digital wide dynamic range does not achieve the purpose of expanding the imaging dynamic range in the true sense, but improves the contrast of the local area through the image post-processing algorithm of the software, which is generally realized by the camera ISP module. These faint differences are enhanced by image processing algorithms to be distinguishable enough by the naked eye.
The IP intelligent camera with wide dynamic range technology have become an important benchmark to measure the performance of a camera. From the current point of view, equipping the camera with a wide dynamic range has become the consensus of all IPC manufacturers.
1. Intelligent analysis of diagnostics. The diagnostic intelligent analysis of the camera is mainly to accurately analyze, judge and alarm for common camera failures such as black screen, blur, pan-tilt out of control, and picture freezing in the video image, and video signal interference (such as scene changes, etc.).
2. Intelligent analysis of recognition. This camera technology is biased towards the analysis and processing of static scenes. Through core technologies such as image recognition, image comparison and pattern matching, the extraction and analysis of relevant feature information such as people, cars, and objects are realized. For example, the parking lot camera system mainly uses the license plate recognition technology in the recognition and analysis of the car.
3. Behavioral intelligence analysis. This technology of IP intelligent cameras focuses on the analysis and processing of dynamic scenes. With the built-in artificial intelligence chip, the front-end camera can analyze the video content in real time, detect moving objects, identify the attribute information of people and cars, and transmit it to the central database of the back-end artificial intelligence through the network for storage.
