基于Webots汽車起重機(jī)工作場(chǎng)景的感知與路徑規(guī)劃研究
[Abstract]:The lifting process of automobile crane is complicated and it is very difficult to make the lifting scheme. The quality of the hoisting scheme directly affects the safety and cost of the hoisting, and the truck crane takes a large proportion in the hoisting work by using its own advantages. In the face of the increasingly complicated hoisting and hoisting environment, only relying on artificial experience to complete the hoisting work, so that the safety and efficiency of hoisting will be reduced. In order to solve the problem of making the hoisting scheme tedious and improving the safety of hoisting, virtual hoisting simulation technology emerges as the times require. From the view of crane hoisting safety, based on Webots simulation software, this paper studies the working scene perception and path planning algorithm of automobile crane in 3D virtual hoisting environment, to understand the relationship among hoisting objects, obstacles and cranes. Search for an optimal path between obstacles to ensure hoisting safety. The main work includes: first of all, the actual hoisting technology, main technical parameters, basic operation, sensing system and hoisting path parameters of truck crane are analyzed in detail. The model of hoisting environment is established in Webots. Through the perception system of crane, the lifting scene graph is obtained, and the information of hoisting work scene is perceived, so as to prepare for the research of path planning. Secondly, the starting point and the target point of hoisting are determined according to the movement characteristics and station position of crane hoisting. A path planning algorithm based on improved genetic algorithm is proposed. The lifting path space is divided into multiple path planes and the path plane model is established by using the job scene model and the position and pose space model of truck crane. Finally, the path information model based on genetic algorithm is used to determine the crane hoisting path. By adding bounding box attributes (i.e. boundary object attributes) to the scene model, the algorithm improves the search accuracy and improves the computing rate and convergence speed by using memory operators. Finally, on the platform of virtual hoisting software, VRML97 programming language is used to complete the simulation test of virtual hoisting.
