A Method for Constructing Adaptive Grid Digital Depth Model Considering Depth Complexity
摘要
Abstract
Aiming at the drawbacks of not being able to automatically adjust depth space according to depth variance in different sea areas in traditional methods for constructing digital depth model (DDM) ,a method for constructing adaptive grid DDM considering depth complexity is proposed. A standard for evaluating depth complexity is founded;the intemal relationship is mined among depth complexity, grid resolution and accuracy of grid DDM, and adaptive grid DDM considering depth complexity is constructed. Experimental results demonstrate that the proposed method can automatically adjust grid generation level according to the requirement of DDM accuracy, and improve the accuracy of grid DDM.关键词
