<P>PROBLEM TO BE SOLVED: To provide an all-around image measurement device capable of generating an all-round image with simple device constitution and measuring three-dimensional data on a measurement object positioned at the whole circumference. <P>SOLUTION: The all-around image measurement device includes a horizontal turntable 4 which is supported horizontally by a support part 1 and provided rotatably in a horizontal direction; a horizontal rotary driving part 3 which can rotate the horizontal turntable 4 at a constant speed; an EDM device 11 and an imaging device 12 which are provided at the horizontal turntable 4; and a control part 13 which performs synchronous control over range finding by the EDM device 11 and imaging by the imaging device 12. The control part 13 controls the horizontal rotary driving part 3 to rotate the horizontal turntable 4 at intervals of a predetermined angle of rotation and to place the imaging device 12 in operation, and acquires a single image at each predetermined angle of rotation over the whole circumference and then puts single images together to generate an all-around image. Further, the control part 13 rotates the horizontal turntable 4 and scans range finding light from the EDM devices at intervals of the predetermined angle of rotation to find a range over the whole circumference, and computes a horizontal angle and a perpendicular angle of the range-finding point from the all-around image to acquire three-dimensional data on the measurement point. <P>COPYRIGHT: (C)2012,JPO&INPIT |
