The invention discloses a multilayered dynamic collision detecting method and system for a blade production line, wherein the method comprises the following steps of: acquiring a model list of objects to be detected; acquiring a bounding box of moving objects and a bounding box of static objects in the objects to be detected, and acquiring a surface list by virtue of a projection detection algorithm of the bounding boxes; acquiring the surfaces of the moving objects and the surfaces to be detected on the static objects in the surface list, and acquiring and storing a first surface pair to a surface pair list by a surface projection detecting algorithm; acquiring the first surface pair in the surface pair list, and acquiring and storing a first triangular surface patch pair to a triangularsurface patch pair list by virtue of a triangular surface patch projection detecting algorithm; and acquiring the first triangular surface patch pair in the triangular surface patch pair list, and detecting whether the first triangular surface patch pair is interfered by an accurate triangular surface patch detecting algorithm. By utilizing the multilayered dynamic collision detecting method and system disclosed by the invention, the time for collision detection can be reduced, and the collision detecting efficiency can be improved.
Description
technical field [0001] The invention relates to the field of automation, in particular to a multi-level dynamic collision detection method and system for a blade production line. Background technique [0002] The blade production line is a relatively complex scene, which contains both static objects and moving objects. In order to avoid collisions between objects, it is necessary to model and simulate the blade production line to find out whether there is a collision during the movement of objects in time to avoid losses in the actual production process. Such as: collisions in the hoisting of large blades, collisions between trolleys in the workshop logistics system and other stationary objects, collisions between blades, CNC machine tools and tools during blade clamping, etc. [0003] At present, collision detection methods in complex scenes mainly include static collision detection methods and dynamic collision detection methods, and dynamic collision detection methods ar...
