Geometrically calibrating a device is not just a simple matter of running an image of a checkerboard through Imatest software. It requires prior information about the nominal device specification and a considered test setup appropriate to the device. In return, Imatest can produce consistent and accurate calibrations even for challenging devices in a constrained setting (such as a production line).
Designing a calibration program for your device
Before you are able to make proper, accurate use of the Geometric Calibrator, you should:
- Determine your accuracy requirement for the parameters to be calibrated.
- Gather the nominal device specification values for your system, including the field of view for all devices, hyperfocal distance, and sensor pitch.
- Understand the Required Evidence for calibrating a system, how the Calibration Procedure will make use of it, and how the evidence required relates to your requirements.
- Decide upon a Supported Target configuration based on your device(s’) parameters and the space allotted by your Test Setup.
