Study of the TIN Gross Error Detection based on Terrain Inclination

Sheng Qinghong

Abstract—Surface model construction is the basis of three-dimensional model representation and contour drawing. This paper constructs Delaunay triangulation (TIN) with three-dimensional points first, then discusses the unreasonable contour configuration produced by the triangulation data, analyzes the source of errors, and points out that gross errors and random errors are made in the process of image matching and orientation. This paper puts forward a method of TIN gross error detection by using determined points and neighborhood inclinations, which is proved to be a simple and effective method of gross error detection and can eliminate serious distortions of contours in points of gross errors.

Index Terms—digital elevation model; triangulation; contour;gross error detection
