Abstract—In view of the existing situation of papayas quality
detection in our country, a visual detection system for quality
of papaya surfaces is presented in the paper. In order to
acquire comprehensive information on papaya surfaces, an
inclined plane with small angle is employed as the work
platform for image acquisition of papayas, and the inclined
angle can be fixed through calculation while making papayas
roll purely along the slope. The result of the experiment
indicates that the visual detection system can acquire
comprehensive information of papaya surfaces. The system
with the advantages of simple structure and low cost appears
obvious contribution to avoid the complex mechanism in
actual production.
