Description

Technical Field

[0001] The present invention relates to the technical field of cameras, and in particular to a camera detection, calibration and debugging system. Background Art

[0002] A camera, also known as a computer camera, computer eye, electronic eye, etc., is a video input device that is widely used in video conferencing, telemedicine, and real-time monitoring. A camera generally has basic functions such as video recording / transmission and static image capture. After the lens captures the image, the photosensitive component circuit and control component in the camera process the image and convert it into a digital signal that can be recognized by the computer. Then, the image is input to the computer through a parallel port or USB connection, and the software restores the image. The main functions of a camera include video recording and static image capture. It can support multiple interface types, such as serial port, parallel port, USB, and IEEE1394. In addition, the image sensor of the camera can be CCD or CMOS, which determines its imaging quality and performance. The camera usually has the characteristics of high sensitivity, strong light resistance, and small distortion, which enables it to provide clear images in various environments. Surveillance cameras, as a special application form of cameras, are often used in security systems. They have the advantages of anti-vibration and long life. The camera needs to adjust its monitoring angle during installation. The camera can be divided into two categories: digital cameras and analog cameras. Digital cameras can convert the analog video signals generated by video acquisition devices into digital signals, and then store them in the computer. The video signals captured by analog cameras must pass through a specific video capture card to convert the analog signals into digital modes and compress them before they can be converted to the computer for use. Digital cameras can capture images directly and then transmit them to the computer through serial, parallel or USB interfaces. No matter which type of camera is installed, it needs to be debugged, so a camera detection, calibration and debugging system is required.
