Latest Patents

One of Changchun Li's latest patents is focused on the calibration of a lidar sensor. This system is designed to determine the pose of a lidar sensor within an environment, facilitating its calibration. The system utilizes at least two calibration boards, each with defined edges. A controller is connected to the lidar sensor, directing it to perform scans of the calibration boards. By analyzing the reflections received from these boards, the controller can identify crossing points and establish a reference plane, ultimately determining the lidar sensor's pose.

Another notable patent involves visual robot pose estimation. This method estimates a robot's pose using two co-planar points and lines on an object plane. The process includes capturing images with a camera mounted on the robot, projecting observed points and lines, and calculating projection errors. If these errors fall below a predetermined threshold, the current pose of the robot can be accurately estimated.
