Abstract
The present invention relates to mine surveying. The proposed invention makes it possible to carry out geodetic mine surveying operations with unprecedented ease. The invention is a reliable primary device for carrying out the majority of geodetic mine surveying operations and will significantly reduce the amount of time needed to carry out geodetic mine surveying operations while requiring only a small number of specialists.
Claims
1. A device for conducting surveying work, which is made distinct by the fact that it is a fixed GNSS base and a mobile ‘Rover’ consisting of a head-mounted virtual reality display with a transparent display with the ability to display data for surveying and geodetic works, and made with the ability to track the location of the device and the direction of the operator's gaze, while in the absence of a satellite connection The Rover navigation system uses a system of gyroscopes and accelerometers to find the exact location.
2. The method of conducting surveying work, which is made distinct by the fact that the device is used according to p. 1, using virtual/augmented reality, satellite navigation system to find the exact location, while, in the absence of a connection with the satellite navigation system, the rover uses a system of gyroscopes and accelerometers to find the exact location during surveying and geodetic works, in addition, the rover tracks not only the location of the device, but also the direction of the operator's gaze, The rover shows the data necessary for surveying and geodetic works through a transparent virtual reality display.
Description
[0021] Thus, the invention is a reliable main device for carrying out most surveying and geodetic works, it will greatly reduce the required time for conducting surveying and geodetic works and will need a small number of specialists.
[0022] The usage cycle consists of the following steps: [0023] 1. Turn on the GNSS database and calculate the exact location of the GNSS database. [0024] 2. Turn on and prepare the Rover to calculate the coordinates. [0025] a) If it is possible to connect to satellites: enable GNSS trackers and calculate coordinates through the received data. Turn on the gyroscopic and accelerometric systems and calculate the direction of view through the received data. [0026] b) If it is not possible to connect to satellites: install the Rover in a special compartment and calculate the exact location of the Rover, turn on the gyroscopic and accelerometric systems. From that point onwards data on the location of the Rover will be obtained from gyroscopic and accelerometric systems. Data on the direction of the operator's gaze will be obtained from the gyroscopic and accelerometric systems. [0027] 3. Put the Rover on the operator. [0028] 4. Perform the required surveying and geodetic works. [0029] 5. At the end of the work, turn off the Rover and GNSS base.
[0030] The device has sets of electric batteries. The operator at work will be required to have spare electric batteries in case of electric batteries in the device running out.
[0031] Method of conducting surveying work:
[0032] Let's consider the method of conducting surveying work on the example of a typical surveying task in open-pit mining—to set the boundaries of the block allocated for explosion. To do this, the exact coordinates of characteristic points in space are taken from the mining plan.
[0033] To get started, you need to turn on the GNSS Database and prepare it for work, namely: calculate the coordinates of the location of the GNSS Database. Next, you need to turn on the GNSS Rover and calculate the exact coordinates of the GNSS Rover location. This is done in one of the two ways described in the device usage cycle [usage cycle 2.a) and 2.b)].
[0034] With the GNSS Base and GNSS Rover connected, you can start working. The operator needs to put the rover on his head. When entering coordinates of the earlier mentioned points, the Rover will project the exact position of the characteristic points in space onto a head-mounted virtual reality display with a transparent display. Thanks to the transparency of the display, the operator will be able to see both the actual situation and the projection of characteristic points on the actual situation. The ability to see the exact location of characteristic points will allow the operator to quickly find these points and mark them in space using wooden stakes or other means. This ends the surveying task of setting the boundaries of the block allocated for the explosion. The speed of finding characteristic points by means of projection on a transparent display will save the company the time of a specialist, which will lead to higher productivity of the said specialist.
