The spliced driving calibration plate is a special tool for the calibration of autonomous driving systems. It is typically made up of multiple calibration plates, each with a specific combination of reflectivity, that is used to determine the location of feature points in a lidar or camera image. By using a tiled driving calibration board, the perception accuracy and positioning accuracy of the autonomous driving system can be calibrated and verified.
There are many factors that need to be taken into account in the design and manufacture of the tiled driving calibration plates, such as the choice of reflectance combination, the size of the calibration plates, the arrangement, lighting, and the background. Proper design and use of calibration plates can ensure the accuracy of the autonomous driving system, thereby improving the safety and comfort of driving.
When using a stitched driving calibration board, the board is placed in the field of view of the autonomous driving system and a series of images are taken using a lidar or camera. The autonomous driving system can then automatically identify feature points in the image and use these feature points to calculate the internal and external parameters of the machine vision system. These parameters can be used to calibrate the perception accuracy and positioning accuracy of the autonomous driving system.
In conclusion, the spliced driving calibration board is a very useful tool that can help users calibrate and verify the perception accuracy and positioning accuracy of autonomous driving systems.
