2026-05-29 Dataset of Underwater Obstacle for Collision Risk Assessment doi:10.57760/sciencedb.37956 en This is the data for the simulation and field experiments in [Collision Risk Assessment Considering Parametric Uncertainty of Unknown Underwater Obstacles].For simulations, there is the full data for CA and CT Motion Scenarios. The observed positions of the obstacles are stored in CA_observ and CT_observ. The first and second lines in CA_observ and CT_observ represent the observations without noise, while the third and fourth lines represent the observations with noise.For field experiments, there are three groups of sonar figs named by "153300", "154300", and "154900". Each fig has two format which are pgm and ppm. All figs are presented in rtheta frame. collision; risk; assessment Lin XiaoYang Wu Jianbo Wang Qing Li Jiangxiong Ke Yinglin PUBLIC https://creativecommons.org/licenses/by-nc-nd/4.0/ dataset Science Data Bank
