Digital videohydrostatic leveling unit
The peculiarity of the digital video hydrostatic leveling unit is to make measurements based only on the Y-coordinates of the contour points of the images of the sighting targets in the video signal generated by the modular video camera, which is part of the video sensor mounted on the hydrostatic level vessel. This allows significantly reducing the dimensions of the video processor, placing it directly in the video sensor, ensuring its work in digital format. Using a common trunk cable, video sensors are connected in series to a computer, which can significantly reduce the total cable length and increase the reliability of the video hydrostatic level. Measurements are performed under the control of a special applied computer program recorded in nonvolatile computer memory. The measurement results are displayed on the monitor and recorded in the archive file of the computer.
