| Description: | Close range photogrammetry and vision metrology often use signalised points in the form of active or passive targets. Many theoretical and some practical tests of different target image centring algorithms have been carried out. This paper will describe the empirical testing of several such algorithms using real data acquired for industrial measurement projects and camera calibrations. The precision and accuracy of the centring algorithms will be characterised by analysis of self calibrating network solutions using multiple camera stations and a target array. Particular emphasis will be placed on the comparison between centroiding and ellipse fitting to locate target image centres. |
