Magnetic coding point
Special coding points for 3D Photogrammetry
In hl-3dp, magnetic coding points are used to orient the picture and automatically calculate the position of the camera. When taking pictures, we should try to capture more marker points walking evenly on the object, so as to obtain higher measurement accuracy. In general, magnetic coded points are not used to determine the three-dimensional coordinates of the measured object. Hl-3dp can handle 10 bit (100), 12 bit (300) and 15 bit (420) marker points. For example, a 10 bit mark point system means 100 mark points identified by numbers from 0 to 99.
There is a black-and-white ring around the coding mark point, and the number of equally divided copies of the ring is the number of digits of the coding mark point.
