A METHOD OF ACQUIRING 3-DIMENSIONAL COORDINATES OF SHORT RANGE MULTIPLE IMAGES WITHOUT SURVEYING REFERENCE POINTS

摘要

The present invention relates to a method for acquiring three-dimensional information from near multiple images without performing a reference point survey. More specifically, the present invention does not use expensive precision surveying equipment in close-up photogrammetry, and the target or mark installed in the target area is photographed together with the photograph or image, so that the target without surveying the reference point Or a method for acquiring reference point information from the scale. To this end, in the present invention, a target for measurement or measurement is installed in a target area, and multiple images of the target area including the target or target are photographed to acquire an image and simultaneously use the target for measurement or measurement indicated in the image. It will be used as information. This is a method of obtaining reference point information of a target area without performing a reference point survey in the field, and by using the obtained reference point information and the existing luminous flux adjustment method, three-dimensional coordinates of the target area can be obtained.;Stereoscopic image, 3D information, reference information, near field surveying, luminous flux adjustment
