In vision, everything depends on image acquisition, and in image acquisition, everything depends on illumination. Naturally, robust algorithms can be designed to largely overcome any problems of inadequacy on these fronts. On the other hand, care with acquisition often means that simpler, more reliable algorithms can be produced. This chapter considers these important aspects of vision system design.
Look out for:
• lighting effects, reflectance, and the appearance of highlights and shadows.
• the value of soft or diffuse lighting.
• how lighting can systematically be made uniform by use of several point or line sources.
• the types of cameras that are commonly available.
• the sampling theorem and its implications.
