Since a single camera has a limited

Since a single camera has a limited field of view, two digital cameras can be used to collect fabric photos simultaneously. Digital cameras can record images in memory through the lens and photosensitive device, and the imaging quality depends largely on the quality of the lens and the pixel level of the photosensitive device, i.e. resolution. There are different types of lenses, such as fixed focus, zoom, telephoto, optical focus, and fisheye lenses, and can meet different shooting needs in different situations. Photosensitive devices are mainly divided into two types: CCD and CMOS currently used. The difference between the two images is small. It is the pixel value that really determines the shooting quality. Cameras from hundreds of thousands to tens of millions of pixels are very common.
