Abstract

To improve the depth accuracy of consumer-grade RGB-D cameras, this paper proposed a two-stage depth correction algorithm based on an error component model. The algorithm established an error component model by analyzing error characteristics, employed an iterative calculation approach that progressed from short to long distances, and designed a two-stage depth correction algorithm. This paper explored the effect of pixel discretization on correction accuracy, applied the algorithm to a bathing robot, and compared its performance with that of another depth correction algorithm. The results indicate that this method effectively reduces depth errors, with better performance observed as pixel discretization becomes denser. In practical applications, the algorithm consistently minimizes depth errors and demonstrates superior performance at longer distances compared to alternative correction methods. The algorithm not only enhances the depth accuracy of consumer-grade RGB-D cameras but also features a simple data collection setup, making it suitable for sensors that generate RGB images, depth images, and point clouds.
