Claim 0:
1. A method for data fusion between calibrated heterogeneous sensors, comprising:
identifying image data and point cloud data for a search area by each of a camera sensor and a LiDAR sensor that are calibrated using a marker board having a hole;
recognizing a translation vector determined through calibrating of the camera sensor and the LiDAR sensor; and
projecting the point cloud data of the LiDAR sensor onto the image data of the camera sensor using the translation vector to fuse the image data and the point cloud data,
wherein the translation vector is determined based on a first distance from the camera sensor to the marker board and a second distance from the LiDAR sensor to the marker board, and
wherein the first and the second distances are determined using a focal length of the camera sensor, a radius of the hole in the marker board, and a radius of the hole recognized through each of the camera sensor and the LiDAR sensor.
