The quality and quantity of vision algorithms available today are greater than before.

To ship consistently high-quality products while keeping costs down, companies are incorporating more automated inspections into their manufacturing processes. Photoelectric sensors can handle simple visual inspections, but complex inspections require machine vision. The range of machine vision products available-from off-the-shelf $1,000 vision sensors to custom systems that run tens of thousands of dollars-create opportunities for automation, while reducing waste and improving productivity.
