Abstract

PURPOSE: To easily measure a solid shape and to quickly obtain a contour line drawing and a border line drawing by irradiating an optical plane over the whole periphery of an object to be measured and bringing an optical intersection part to image pickup by an image pickup device whose optical axis is perpendicular to the optical plane, and also, executing the image pickup, while varying the position of the optical intersection part against the object.
CONSTITUTION: When an optical plane P is irradiated over the whole periphery of the object 10, and its optical intersection part S is brought to image pickup by an image pickup device 7 whose optical axis L is perpendicular to the optical plane P, the image of a border line in the optical plane P of the object 10 is obtained. Subsequently, while holding an interval between the optical plane P and the image pickup device 7 in a prescribed distance, the irradiated position of the optical plane P is moved by a necessary distance in the direction perpendicular to the optical plane P, and when the image pickup is executed again in this state, a border line drawing in a different cutting plane of the object 10 is obtained. In such a manner, by moving stepwise the irradiated position of the optical plane by a necessary distance each and executing successively its image pickup, a contour line drawing when the object 10 is brought to plane vision from the direction perpendicular to the optical plane P can be easily generated.
