This includes not only the field of view, but also essential parameters such as the distortion coefficient or the movement of the nodal point during zoom and focus movements. This leads to the highest matching precision for your Augmented Reality application.
the procedure of automated image processing
We have invented this unique method of lens calibration for all our camera tracking systems. In contrast to other measurement methods offered on the market today, our approach is based exclusively on automated image processing process and not on the manual setting and experience of an operator. Our software automatically moves the lens through the entire zoom and focus range and records a three-dimensional calibration object. From this, our smart algorithms generate a lens file with all optical parameters. This can then be used by any of our camera tracking systems for real-time operation.
fast and easy exchange of different lenses
If different lenses are to be used during production, the appropriate lens files can be loaded into the camera tracking system. Meaning that the lens can be changed quickly and easily. If the centre of the image needs to be adjusted, the operator himself can readily do this without much ado.
measurement of the focal distance defocusing virtual objects
The focal distance is measured as a further parameter. This is the distance at which the lens will focus. Based on this data, the graphic system can render the virtual objects in front of and behind this distance blurred. This creates a natural image impression, like a real, photo-realistic image.
