Circle Dot Test Calibration Target Plate Product Overview

High-precision circular dot calibration plates serve as fundamental measurement tools for machine vision and metrology, featuring precisely dimensioned dot patterns arranged in orderly arrays. Coligh, as a manufacturer of dot calibration plates, employs photolithography on soda-lime glass, fused quartz, and ceramic substrates to produce dot array calibration plates. These are widely utilized in machine vision applications for lens distortion correction, multi-camera synchronization, and robotic navigation and guidance. We offer dot grids with dot sizes of 0.01mm and larger, customizable from small to large dimensions.

Circle Dot Test Calibration Target Plate Applications

• Machine Vision
  On automated production lines, camera lenses introduce distortion that causes image distortion. Therefore, cameras must be calibrated to eliminate system errors. A calibration target allows the camera to capture images of the target from multiple angles and positions. Vision software then calculates the camera parameters to measure all workpieces.
• Robotic Vision
  For robots to accurately grasp or manipulate objects, precise spatial relationships between the robot’s end-effector and camera must be known. By positioning a fixed calibration plate at various locations while the robot’s end-effector moves the plate to different positions, a stationary camera captures images. This enables precise grasping and placement.
• 3D Scanning
  Multiple components of 3D scanning systems, such as structured light and laser systems, require operation within a unified, precise coordinate system. By scanning and capturing the calibration plate from multiple angles using the 3D scanning system, the relative position and orientation between the camera and projector can be calculated to ensure the accuracy of the 3D data.
