Abstract:
1. A three-dimensional (hereinafter referred to as “3D”) collision detection system for a measuring machine implemented by a computer, the system comprising: a parameter inputting module configured for inputting various parameters of a to-be-measured workpiece and a moveable arm; a model simulating module configured for simulating a to-be-measured workpiece 3D-model in accordance with the parameters of the to-be-measured workpiece, and a moveable arm 3D-model in accordance with the parameters of the moveable arm, and for combining the to-be-measured workpiece 3D-model with the moveable arm 3D-model to form a 3D collision model; a calculating module configured for calculating various positional coordinates of the moveable arm according to the 3D collision model to generate a measuring path of the moveable arm; a collision predicting module configured for detecting whether the moveable arm collides with the to-be-measured workpiece according to the measuring path; and a processing module configured for plotting the measuring path with a first color from a take-off point to a collision point if the moveable arm collides with the to-be-measured workpiece, or plotting the measuring path with a second color from the take-off point to a terminal point if the moveable arm does not collide with the to-be-measured workpiece.
