1 Use a high-brightness uniform backlight or shadowless light source; the purpose is to make the edge contrast good
2 High depth of field telecentric lens using Dehong Technology; the purpose is to make the product clear at a certain height
3 cooperate with precise mechanical platform, stable alignment software system,
