DATA PROCESSING APPARATUS, DATA PROCESSING METHOD, AND COMPUTER READABLE MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18221472 titled 'DATA PROCESSING APPARATUS, DATA PROCESSING METHOD, AND COMPUTER READABLE MEDIUM
Simplified Explanation
The patent application describes a system for estimating the movement of a vehicle using both camera and LiDAR data.
- The system includes a camera installed on the vehicle and a camera movement amount acquisition unit that calculates the estimated movement amount of the vehicle based on the image data captured by the camera.
- In addition to the camera, the system also includes a LiDAR movement amount acquisition unit that calculates a more accurate estimated movement amount of the vehicle using LiDAR data.
- The camera movement amount and the LiDAR movement amount are acquired in synchronization with each other.
- A comparison decision unit compares the camera movement amount with the LiDAR movement amount.
- If the difference between the camera movement amount and the LiDAR movement amount is less than a threshold value, the system decides to use the camera movement amount for a calibration operation.
Original Abstract Submitted
A camera movement amount acquisition unit () acquires as a camera movement amount (), an estimated movement amount of a vehicle () calculated using photographed image data acquired by, a camera () installed on the vehicle (). In synchronization with the acquisition of the camera movement amount () by the camera movement amount acquisition unit (), a LiDAR movement amount acquisition unit () acquires as a LiDAR movement amount (), an estimated movement amount of the vehicle () with higher estimation accuracy than estimation accuracy of the camera movement amount (). A comparison decision unit () compares the camera movement amount () with the LiDAR movement amount (), and decides to use the camera movement amount () for a calibration operation when a difference between the camera movement amount () and the LiDAR movement amount () is less than a threshold value.
