Embodiment Construction
[0074] The invention patent consists of two parts: figure 1 The shown computer and its camera measurement system, figure 2 The shown camera axial displacement device is composed of high-precision micro-displacement stepping motor as the core.
[0075] On the computer system (5), run the camera driver program (13) for distribution, and connect the camera (1) to the computer (5) through USB interfaces (4) and (6). Then, let the camera focus and image the object to be measured.
[0076] During the measurement process, certain changes in lighting conditions are allowed, as long as the changes do not significantly affect the contrast between light and dark imaged by the measured object. Selecting lighting equipment (15) is helpful to the implementation of the present invention. For example, the uniform lighting method with diffuse reflection, or the intensity of the lighting equipment can be stronger than the influence of ambient stray light. The material of the object to be m...
