AI Technical Summary
Existing technologies struggle to effectively verify the calibration status of multiple environmental detection sensors in vehicle environments, especially in non-overlapping scan areas and unmapped environments, and require reliance on map verification or identification of common targets.
By determining the homogeneous coordinate transformation, the coordinates of the sensor coordinate system are converted to the vehicle coordinate system. The sensor misalignment state is identified by using relative velocity and vehicle motion model, and the calibration state is verified by statistical methods without relying on maps and common targets.
It enables more reliable verification of sensor calibration status in non-overlapping scan areas and unmapped environments, improving the reliability and fault tolerance of vehicle attitude recognition and reducing reliance on maps and target recognition.
