Fidelity Evaluation of Bridge-Type Grab Ship-Unloader Visual Simulation

Abstract

Visual simulation's fidelity is used to verify the similar degree of simulation system that simulates real word. How to improve the similar degree of visual simulation is the key way to meet the simulation performance. Based on the F-AHP method, this work establishes the evaluation model of visual simulation fidelity of bridge-type grab ship-unloader, giving determining method of evaluation indicators, establishing membership function of each indicator and determining the weight. Finally, the case study is taken to illustrate how to evaluate a specific visual simulation with the method proposed in this work, and the evaluation result shown the fidelity of the virtual scene we gave is not so well.
