Page 4: Introduction
GEOCAL/GEOCAL XL consists of an illuminating hardware device and software for the geometric calibration of camera systems. The GEOCAL software is used for calculating the calibration parameters f rom a single image taken with a camera system of the point grid generated by the GEOCAL hardware device. -
Page 5: Getting Started
The power socket and the main power switch are located on the back side of the device next to the USB type B socket. Connect GEOCAL/GEOCAL XL to a power outlet and switch it on. Please note that the blue LED next to the power switch indicates that the power line is active and that GEOCAL is ready f or operation. -

The autof ocus must be turned of f . Since GEOCAL / GEOCAL XL uses a collimated light beam virtually originating from infinity, the appropriate f ocus distance will be near inf inity. Using manual f ocus, ensure the camera is f ocused on the light points. -
Page 7: Camera Position And Suitable Lenses
The camera rotation to the DOE is part of the calibration and is determined during the process and reported as part of the result. The lens's f ront element must not be larger than 77 mm in diameter for GEOCAL or 155 mm for GEOCAL XL to capture the point grid in f ull f ormat. -

Do not change the camera's orientation between images because the points would no longer be aligned to one another through multiple images. Image Engineering Seite 8 von 16... -
Page 9: Differences Between Geocal And Geocal Xl
4 DIFFERENCES BETWEEN GEOCAL AND GEOCAL XL The key difference between GEOCAL XL and the standard GEOCAL is the physical size of the dif f ractive optical element (DOE) that generates the point grid. While the standard GEOCAL has a usable diameter of 77 mm, the GEOCAL XL provides a f unctional diameter of 155 mm. -
