A rapid path planner for autonomous ground vehicle using section collision detection 总被引:1,自引:0,他引:1
Rapid path planner plays an important role in autonomous ground vehicle (AGV) operation. Depending on the non-holonomic kinematics
constraints of AGV, its path planning problem is discussed. Since rapidly-exploring random tree (RRT) can directly take non-holonomic
constraints into consideration, it is selected to solve this problem. By applying extra constraints on the movement, the generation
of new configuration in RRT algorithm is simplified and accelerated. With section collision detection method applied, collision
detection within the planer becomes more accurate and efficient. Then a new path planner is developed. This method complies
with the non-holonomic constraints, avoids obstacles effectively and can be rapidly carried out while the vehicle is running.
Simulation shows that this path planner can complete path planning in less than 0.5 s for a 170 m×170 m area with moderate
obstacle complexity.
