Method and device for detecting propellers with high-precision

Abstract

A method and device for detecting propellers with high-precision, comprising: obtain a measurement point cloud of the propeller, filter the measurement point cloud to obtain a target point cloud; process the target point cloud to obtain a first measurement plane, and find a center point of a pressure cone point cloud; obtain a measuring axis according to the first measurement plane and the center point; segment the target point cloud to obtain a blade point cloud of each blade, and analyze the blade point cloud and the measuring axis to obtain the parameters of the propeller, so as to determine whether the propeller is qualified. The present application uses a high-precision structured light 3D camera and a convenient portable, simple and high-precision detection solution for propeller products developed based on the open source 3D algorithm framework PCL. The device can improve the detection efficiency and the feasibility of promotion.
