I have the latest Recap 360 Pro (April 2017) and having issues with assigning survey points to the project. Faro FLS scans included 4 checkerboard targets around a pump station building walls. I have successfully imported, registered and indexed 32 scans with no issues. All functions in Racp appear to work OK including export to E57 etc. I have been given the survey data (E, N and Elev) by the surveyor in Australian MGA-56 zone format. I created a TAB delimited txt file as follows:
2 6938544.174 502873.622 67.427
1 6938550.383 502866.878 67.413
3 6938558.714 502868.886 67.748
4 6938554.351 502874.971 67.533
Units are in meters. The txt format as I understand it needs to be ID, N, E, Elev(Z)
I first go to settings and set Co-ordinate system to "MGA-56" and for viewing set x=E, y=N and z=z.
Then I go to Registration page, find my targets and set them as Survey Points. In dropdown I first choose "Upload Survey Points (.txt) - [Survey format N, E, Elev]" and go find my file and pick it. Then back in dropdown I find the 4 ID numbers and choose the correct one for the checkerboard (1 is my first marker). Repeat this for markers 2 and 4. Marker 3 checkerboard does not get recognised because the Faro scanner photo on that marker was blown out by bright light. All done, I go back to the Project. It does some calcs and then bingo, the whole cloud turns upside down!! OK, bizaar, but if I go to the survey markers in 3D view and point at the centre of a previously selected survey marker, it is NOT correct. Maybe out by 1 meter or so on N or E. When I export upside down cloud to E57 and open in CloudCompare it starts upside down. Even there the co-ordinates are way off being accurate.
Why does the cloud invert? Why are the locations of survey markers so inaccurate?
I need some help please because my customer is relying on me setting the cloud to an accurate survey. I have spent a huge amount of time trying to figure this one. A challenge!!
