NONCONTACT THREE-DIMENSIONAL MEASURING METHOD AND DEVICE

摘要

[PROBLEMS] The length, area or volume of the whole or a specific portion of a building of any type can be measured with simple operation by using a simple device. [MEANS FOR SOLVING PROBLEMS] An object is imaged by a digital camera from positions along a vertical line. From the level difference between the position of each measurement point on the object shown in each image and each of the imaging points, the lengths between the measurement points, the area and volume surrounded with the points are determined. A digital camera is mounted on a platform of a tripod. While changing the vertical level of the platform, the object is imaged from a plurality of positions. The images and information on the imaging point levels are inputted into a computer. One of the measurement points on the object shown in one image is clicked on the display to allow the computer to perform calculation. [EFFECT] The device cost is low, and the operation is easy. The method and device is extremely effective for use especially not requiring high precision.
