The superposition of the two cameras is 24 million, but in fact, the two cameras are spaced apart, so it is impossible to completely overlap the captured images, which leads to loss.
Camera, also known as computer camera, computer eye and electronic eye, is a kind of video input equipment, which is widely used in video conferencing, telemedicine and real-time monitoring. Ordinary people can also have video and audio conversations and communication with each other on the Internet through cameras. In addition, people can also use it for various popular digital images, audio-visual processing and so on.
cameras can be divided into digital cameras and analog cameras. Digital camera can convert analog video signals generated by video acquisition equipment into digital signals, and then store them in computer.
the video signal captured by the analog camera must be converted into digital mode by a special video capture card and compressed before it can be converted into a computer for use. Digital camera can capture images directly, and then transmit them to the computer through serial port, parallel port or USB interface.
digital cameras are the main cameras in the computer market, and USB digital cameras with new data transmission interfaces are the main digital cameras, and most of them are visible in the market. In addition, there is a product that works with video capture card, but it is not the mainstream.
due to the rapid popularization of personal computers, the overall cost of analog cameras is high, and the interface of BSV LCD splicing screen cannot be met. The transmission speed of USB interface is much higher than that of serial port and parallel port, so digital cameras with USB interface are on the market.
the analog camera can be used together with a video capture card or a USB video capture card, which is convenient to connect with a computer. The typical application is general video surveillance. Clean area camera, clean area embedded special camera is a special camera for real-time monitoring of key positions of important equipment in clean area clean room. The camera has a flat panel, embedded with color steel plate, zero sanitary dead angle, convenient cleaning, convenient installation, rapid multipoint control and compatibility with mainstream video systems.
