AI Technical Summary

Technical Problem

Existing bamboo joint detection equipment suffers from large errors in image acquisition and processing, making it difficult to accurately avoid bamboo joints and ensure the precision of the bamboo cutting position.

Method used

A bamboo joint measuring device based on 3D line scanning is adopted. The position of the bamboo joint is detected in real time by a 3D scanning camera. The bamboo is moved smoothly by the cooperation of the conveyor roller and the pressure roller and the sliding of the limit block. Combined with the contact switch to control the cutting equipment, precise cutting is achieved.

Benefits of technology

This improves the accuracy of bamboo node detection, avoids deviations in the cut-off position of bamboo node ends, and ensures the accuracy of bamboo flesh thickness and inner and outer diameter detection.
