Abstract
In an autonomous vehicle, accurate location recognition with an object on the road is a very important factor for driving safety. In this paper, we propose an region of interest (ROI)-based location information extraction algorithm that converges a camera and a lidar for accurate location extraction of an object. In general, when the camera and lidar are fused to match the position of an object, a target board such as a chess board is used to calibrate the position difference between the sensors. In the area of interest for object recognition of an autonomous vehicle, a difference in the positions of the camera and lidar occurs depending on the position of the object due to the wide road environment. The proposed algorithm divides the camera image into multiple ROIs and performs the position matching of the camera and lidar independently for each area. We verify the accuracy of the proposed ROI-based positioning algorithm in virtual and real road environment.
