  "textContent": "A photogrammetric method involving two-fold photogrammetry, wherein at each of two installing points of a camera-equipped surveying instrument, an image and an auxiliary image including a measuring point on an object to be measured are acquired, and a rough three-dimensional shape of the object is obtained based on (narrow intersection angle, low resolution) photogrammetry using the image and the auxiliary image, respectively. Whether candidate corresponding points in the first image and the second image are indeed correctly matched in a subsequent (wide intersection angle, high resolution) photogrammetry process is determined based on the rough three-dimensional coordinates of the candidate corresponding points.",
