Geometric Calibration

May 25, 2022

From 2019 to 2021 Imatest offered a Geometric Calibration Solution that determines determines the intrinsic parameters that describe the as-built camera systems, which provides a mapping between image coordinates and directional rays into the world, allowing a computer vision system to derive accurate 3D information about the scene that is being imaged. Our Solution combined analysis software and calibration hardware required for rapid testing in a production line.  In April 2021, this solution was exclusively licensed to Furonteer.  Please contact y.jeong@furonteer.com for more details about the solution.

To accurately determine the specific algorithms and setup requirements in our custom-built machine, please provide camera samples for each product line you wish to test as well as specific project details including the following:

Camera System Lens:

  • Effective focal length (EFL)

  • Field of view (horizontal)

  • Entrance pupil location

  • Nominal distortion function

  • Focus distance/working distance

Sensor (include on the sensor datasheet):

  • Resolution

  • CFA pattern

  • Pixel pitch

Additional information:

  • mechanical information about the cameras

  • image acquisition/capture card

  • accuracy requirements

  • use case 

  • requested time frame
