A new software for the Calibration of large format (full frame) cameras but also for wide angle lens cameras has been developed during my research activities in IUAV at the laboratory of Photogrammetry. The software is using a printed page calibration sheet and the user has to select the surrounding region of a rectangular area of circle reference points” grid to perform the calibration (see the image of the calibration grid below). After the calibration is performed the user can load any image captured from the same camera and the same settings to do the undisortion. Additionally the software can use videos to capture initially the calibration sheet and perform the calibration and since the calibration parameters have been calculated any video captured by the calibrated sensor can be undistorted. You can download the installation application of the software Calib3V and also sample images (see below) of a wide angle lens camera.
You can also download and watch the tutorial video from the link.
You may download a sample set of calibration field images to perform the calibration of an action camera from here.
An A4 circular target GCP file maybe downloaded from here.
The camera parameters that the user must insert for the calibration performance of the paradigm set is shown in the next image:
