Triangulation rangefinder

v 1.0.1

Especially for servers on which Raycast is prohibited.

The script allows you to measure distances and determine the coordinates of fixed targets by the method of triangulation, without using Raycast.
To do this, you need to perform several measurements by aiming the camera crosshair on the target and launching the program block with an argument. Each next measurement should be performed by moving a little to the side or vertically from the previous position.
The more measurements will be made, the more data will be to clarify the coordinates. At least two measurements are necessary, the coordinate will be determined with low accuracy.

4-5 measurements from a distance of 5 km give a point with an accuracy of several meters.

The script can also create an arbitrary GPS point at a specified distance along the ray of the camera. To do this, in the Custom Data of the block specified in the settings as "InputCustomDataBlockName", specify the distance in meters. Nothing but numbers, for example, "50000" - the point will be 50 km ahead on the course.

Procedure.
Reduce the power of the gyros to the minimum for comfortable camera guidance with high approximation.
Select a noticeable eye-catching detail on the target; make all measurements relative to this point.
Between measurements, move 100-200 meters to the side.

The principle of determining the coordinates.
At each measurement, the script remembers the ray in space, conducted from the camera in the direction of the target. Each pair of rays forms a triangle in space, the base of which is known. The far end of the triangle is determined by the sine theorem, assuming that the rays intersect at this point.
Thus, the script gets a lot of points formed by each pair of rays, if you combine the rays on the principle of "each with each." Then the center of the "cloud" of the obtained points is determined, as well as the deviation of the points from the center. After this, a center calculation is performed, at which points with a large deviation are ignored.
The result is displayed on the LCD panel in the form of GPS coordinates. It can be copied via the "Edit" menu in the properties of the LCD panel and pasted as the GPS coordinate.

The arguments of the program block:

• addray - remembers the new ray in space and calculates the coordinates
  
• clear - reset all results and clear memory
  
• refresh - recalculation of coordinates and update of information on current distance to the target
  
• addpoint - creates an arbitrary GPS point at a specified distance along the course of the camera

Customization.
When you first start the configuration will be created in the "Custom Data" menu. There you can select a language, as well as specify the names of the blocks. After changing the configuration, you need to recompile the script.

The script does not use Raycast!
Support for Russian and English.
Script Settings via "Custom Data".
Allows you to create an arbitrary GPS point at a specified distance along the course of the camera.

Known issues:
At the surface of the planet, the apparent position of the target is distorted and shifted down the local vertical, so the point is lower than the real position of the target. The horizontal coordinate is determined exactly. Perhaps I will correct this by introducing an amendment, the problem is being studied. Or maybe it's just a glitch of my local world.
