By simply attaching a marker to the point you want to measure on site and uploading two photos to the server, you can automatically measure the 3D coordinates of the marker position and measure the distance between the two points. Places other than markers can also be measured by specifying points on the screen.
The operation is very simple as below. If you place a marker on the part you want to measure, all points will be automatically measured. If you want to measure a place without a marker, calculate by specifying a point on the screen.
