Digital cameras can capture scenes of varying ranges, sizes, and depth of field through zoom or distance with one-time imaging. It is more convenient to shoot real 3D objects, but the pixel level is fixed. In other words, the resolution distance after imaging does not change, it affects the sharpness of object imaging, and the environmental factors as well as the quality of the camera itself have a great influence on the imaging effect of the object, especially light and angle. You can do transformations, etc, so you need to use digital image processing and MATLAB's native methods to sew the collected fabric.
