2.7 Image measurement
The vRTK receivers now have new dual cameras, which support the image measurement function.
The iHand55 and the Hi-Survey software are required; V2.3.0 and later versions must be used.
The image measurement scene is defined as shooting the unreachable position. After the solution is
successfully solved by the controller’s software, the points can be marked on the photo and their
coordinates can be calculated.
