Potato grading is related to weight. Three-dimensional (3D) reconstruction can provide highly accurate volume measurements of potatoes, which help farmers analyze their phenotypic characteristics and grade them. Considering low cost the required accuracy, a monocular camera line laser were used build potato phenotype determination scanning device. The system obtains coordinates along surface potato, collects light reflected from in real time, completes coordinate calculation original points...
