The system utilized four laser scanners along lengthwise direction of the log. Data are obtained in every ten degrees when log is turning, in each cross section, 36 data are obtained. Then the data obtained were processed and an outline of the cross section of the log was developed on computer screen. Afterwards, the largest inscribed circles for log cross sections were determined according to the principle that three points can determine a circle. Secondly, the points located on the cross sections were linked up along some log generative in order to simulate the three-dimension log outline. At last the largest right circular cylinder were optimized and the optimum turning center was determined by means of projective theory.
