Optimisation of camera positions for optical coordinate measurement based on visible point analysis

“…Characterisation of the intrinsic and extrinsic camera parameters is critical for accurate measurement [19]. Camera calibration is a research topic in its own right and is beyond the scope of this work (for more details see [19][20][21][22][23]). Barazzetti points out [10] that as optical coordinate measurement, particularly photogrammetry, has become more accessible, inexperienced users with little measurement experience often produce crude reconstructions at the cost of metric accuracy.…”
