The first development stages of the low cost, PC based, near real time photogrammetry system, PHOENICS, are discussed. Hardware and software components are described and planned system enhancement stages are sketched out. Concepts employed for target detection and analysis are briefly discussed. A target centre detection technique in which a combination of original and thresholded image is employed and a target design especially suited for thresholding techniques are presented. The introduction of parallel processing hardware into PHOENICS during the enhancement phase is explained. Accuracies achieved in first experiments with the prototype of PHOENICS are reported.
