AI Technical Summary
Technical Problem
The shape recognition and positioning of the duct head are difficult to achieve accurately, resulting in large positioning errors when the duct is connected, which affects the gripping effect of the robotic arm.
Method used
A machine vision-based duct head positioning device is adopted, which combines UWB navigation and laser ranging. The duct shape features are obtained through a vision camera component, and the accurate positioning of the duct head is achieved by using binarization processing and laser point cloud formation scheme.
Benefits of technology
It achieves high-precision positioning of duct heads, provides duct position and shape data, simplifies the duct grasping process, and reduces positioning errors.
