Release time: 2022-12-01

Machine vision application of 8 lighting skills:

Tip 1: Detect material defects -- high brightness light;

Tip # 2: Pinpoint -- the right wavelength of light;

Tip 3: Detect scratches on glass -- non-diffuse Light, that is, No-Diffused Light;

Tip 4: Detect transparent packaging - Diffused Light, that is, Diffused Light;

Tip 5: Create contrast -- color light;

Tip 6: Detect fast moving objects -- stroboscopic flashes;

Tip 7: Eliminate reflection -- infrared light;

Tip # 8: Eliminate color change -- infrared light.

There are five aspects to consider when choosing lighting:

1. The surface is smooth or rugged;

2. The surface is dull or bright;

3. The object is curved or flat;
