A distinction method for fruit of sweet pepper using reflection of LED light

This paper describes a distinction method for fruit of sweet peppers, which are grown in greenhouse, using reflection of LED light. Distinction for fruit of sweet pepper is necessary for development of picking robot in greenhouse horticulture. We have been manufactured a prototype of picking robot for sweet peppers. This picking robot has an image processing system using a parallel stereovision, a positioning system to the recognized sweet pepper using visual feedback control, and a cutting device. However, the distinction ability is lacking. We proposed a distinction method for fruits of sweet pepper using reflection of LED light. Experiments were carried out in greenhouse. In consequence, it was possible to improve the distinction ability.
