🟠 Calibration Board Detection
Function Description
This operator is used to detect calibration boards in images and calculate the actual dimensions and spatial pose of the currently detected calibration board.
Usage Scenarios
Generally used in camera calibration and hand-eye calibration scenarios to calculate the relative position between camera and robot.
Input Output
Input |
Camera coordinate system: Point cloud data collected in the camera coordinate system, used for calibration board pose calculation. Image: RGB image for calibration board detection. |
Output |
Dimensions: The actual dimensions of the detected calibration board. Pose matrix: The pose matrix of the calibration board, including rotation and translation information, used for subsequent calibration and coordinate transformation. |
Parameter Description
Calibration Circle Count
Parameter Description |
The number of rows and columns of circular patterns on the calibration board. |
Parameter Adjustment |
For example, [4,5] represents 4 rows and 5 columns of circles. |
Calibration Board Width
Parameter Description |
The actual distance between circle centers on the calibration board. |
Parameter Range |
[0,1000], Default: 35, Unit: mm |
Calibration Board Symmetry
Parameter Description |
Specifies whether the calibration board pattern is symmetric. |
Parameter Adjustment |
Asymmetric calibration boards usually have directionality, making calibration more accurate. |
