Study on a New Movement Algorithm of Tracklayer on Road with Trapeziform Road

In the paper,first, a simplified model on tracklayer is generated and state it illustrated.Secondly, a verticel ray line methodology was introduced into getting the altitude at any point in the 3 dimension space.Thirdly,a state of the art and feasible algorithm is implementd to achieve the coordinate adaption and landform adjustment after the full analysis of the different typical movement state on the trapeziform road, so by which a chanllegening goal is achieved that caterpillar tanker will get through the road with trapezium cross section in the vision simulation system.
