Abstract

In order to find the precise position of the underwater vehicles, suitable matching areas are needed to be decided in the Gravity-matching Aided Navigation System. This paper presents the segmentation suitable-matching areas method of navigation reference map. Firstly, the paper put forward the stability of matching index based on every gridding points in the reference map. The discussion indexes are roughness, main peak curvature of correlation function, trackability, and characteristic density. According to these measures, the suitable matching area was divided by curve evolution using level set method. Several simulations and experiments were performed in this paper.
