Embodiment Construction
[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0033] Concrete steps of the present invention are:
[0034] Step 1: Image Acquisition:
[0035] The light source and image acquisition components are fixed in a black box to form a set of image acquisition equipment. There are two upper and lower rectangular slits on the surface of the black box, and an image acquisition hole is formed between the slits, in which image acquisition components, such as CMOS / CDT lenses or sensors, are built. The black box has two built-in light strips composed of several standard LED light sources, and a diffuser is placed between the light strips and the slit. When the LED light strip is turned on, the light emitted by it passes through the diffuser and the slit to form two uniform rectangular light strips. At this time, the rectangular light band illuminates the surface of the object, and the two-dimensiona...
