英文摘要：

Based on the localizability estimation theory, in this paper, we propose a new method for the reliable self-localization of mobile robots in a disturbed dynamic indoor environment by the adoption of an RGB-D sensor to assist the laser scanner. People＇ s location areas are rapidly detected in RGB-D data, which are then transformed to the laser sensor coordinate to compute the influence of the dynamic obstacles on the laser data. In combination with the discrete Fisher information matrix, we estimate the localizability matrix of the observation information online. In addition, we assess the reliability of the information in odometers by the covariance matrix of the prediction model, thereby dynamically compensating for the effect of the observation information on the particle set. We conducted experiments in a dynamic indoor environment and the results confirm the accuracy and reliability of the proposed robot localization method.
