发明名称 POSITION MEASUREMENT DEVICE AND POSITION MEASUREMENT SYSTEM
摘要 <P>PROBLEM TO BE SOLVED: To provide a position measurement device that has superior maneuverability, and can quickly measure a position with high precision even on a nonflat measurement reference plane. <P>SOLUTION: A camera data measurement device 1 includes a position sensor 100, a cord-like body 200, and an arithmetic unit 300, the position sensor 100 measuring a cord length variation amount of the cord-like body 200 and a cord direction of the cord-like body, and the cord-like body 200 having both ends connected to the position sensor 100 and an imaging camera 900, and the arithmetic unit 300 measuring camera data of the imaging camera 900 on the basis of the cord length variation amount and the cord direction. The arithmetic unit 300 finds the sum of a cord length initial value L0 and the cord length variation amount &Delta;L measured by the position sensor 100 as a cord overall length L in the cord direction, and decomposes the cord overall length L in the found cord direction into three-dimensional components to calculate three-dimensional coordinates showing the position of the imaging camera 900. <P>COPYRIGHT: (C)2013,JPO&INPIT
