- An operator uses the digital tablet to record a video stream which is later taken up by the processing module and reprocessed.
- the digital tablet then uses images at a low level of resolution to determine a first position of itself. It is a pyramid approach where the full resolution image, captured by the high resolution acquisition module, is reduced on several levels. On the processing computer, we then use a higher pyramid level to exploit the full resolution.
