Menetelmä ja järjestelmä konenäköjärjestelmän kalibroimiseksi

摘要

The invention relates to the calibration of a three-dimensional computer vision system. The method and system are implemented using a polygonal plate-like calibration piece (21) made of a material whose properties do not change significantly with changes in conditions or with time. The edges of the calibration piece (21) used have different lengths and the piece is provided with circular focusing marks (22) placed at its vertices.
