摘要
A camera monitors positions on an external object having a beacon (1(i), i = 1, 2,..., I; 130; 430) attached to it. The apparatus has at least one image sensor (120; 321, 322; 420; 520), an imaging optical element (101) for projecting light on the image sensor (120), and a processing unit (9). The imaging optical element (101) may be non-refractive and receives a light beam (5(i); 131) transmitted from the beacon (l(i); 130; 430) and transfers the light beam (5(i); 131) to the image sensor (120; 321, 322; 420; 520). The image sensor (120; 321, 322; 420; 520) forms image data based on the received light beam (5(i); 131) and background light. The processing unit (9) processes the image data such that it filters image data components relating to the background light and renders image data components relating to the light beam.
