PHOTOGRAPHING INFORMATION ATTACHING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a photographing information attaching device that photographs a land and a building so as to use the photographed image for state observation and management. SOLUTION: A distance between a camera 1 and two or more reference points P1-P4 apart from each other on an object 10 is measured and a scale image 11 in parallel with a line segment tying a pair of the reference points is generated. A length measurement scale inversely proportional to a distance between each point on the line segment and the camera 1 is given to the scale image 11. An image output means 8 composites an image obtained by photographing the object 10 with the scale image 11 and displays the result. Thus, the size of each part of the object can be almost accurately visually measured by using the scale image 11. In the case of photographing the object not in front but in an oblique direction, the length measurement scale is given depending on the location to allow a user to visually measure nearly accurate size at any place of the object.
