摘要:
A computer programme for the extraction of information about one or more spatial objects by a person, which programme is designed for analysing the sequence of images in real time, using image analysis techniques, and extracting information about said one or more objects, and communicating at least part of said information to the person in real time via the output means; wherein the programme is preferably designed for calculating an indication as to the realised accuracy of the extracted information about said one or more objects in real time and communicating said information via output means; and wherein the indication about the obtained accuracy preferably comprises an object generated by the central processing unit which is to an increasingly stable degree shown overlapping a current image from the camera on a display screen.
