Abstract
- In recent years, autonomous robots have been practically used outdoors for transportation, delivery, and other applications. To ensure safety and reliability, it is necessary to measure and evaluate the accuracy of a robot's movement from the outside. In this study, we develop a device to externally measure the coordinates and azimuth angle of a robot by combining image processing and distance measurement. In this study, an azimuth angle detection method that combines coarse-angle detection using AKAZE feature detection and small-angle detection using optical flow is proposed. The experimental results show that the azimuth angle can be detected with a standard deviation of σ=0.70° indoors and σ=0.99° outdoors. [ABSTRACT FROM AUTHOR]
