Coding point
Special coding points for 3D Photogrammetry
The coding point is the special coding point for hl-3dp 3D photogrammetry. 3D photogrammetry takes digital photos of the measured object in combination with the coding point. The 3D coordinates of the measured object are obtained by the superposition of 2D digital photos and images. Before the measurement, the coding point will be pasted on the object and then taken with the camera.
During the shooting process, many images from different angles will be taken, and these images will be read into the hl-3dp software. Through the way of triangular ranging, the hl-3dp software will automatically combine these images. After calculation, the 3D coordinates of the center of each coding point can be obtained. Coding point is an indispensable product accessory of 3D photogrammetry system.
