Coordinate System Projection Tool
The Projection Tool projects data from one coordinate system to another:
§ Generate a WKT string that defines a coordinate system (optionally, with vertical datum) for inclusion in Excel/XML photo list files, control point files, and trajectory files.
§ Convert coordinate, OPK, and YPR values from one coordinate system to another.
§ Convert the rotation format from a rotation matrix to OPK/YPR. The rotation matrix transforms coordinates in the specified coordinate system into camera coordinates using: a 3x3 matrix with <Mij> tags, where Mij denotes the coefficient of the (i+1) row and the (j+1) column of the rotation matrix.
§ Convert the rotation format from OPK/YPR to a rotation matrix
To generate a WKT string for a coordinate system:
1. On the Tools tab, in the Coordinate System group, click Reprojection. The Projection Tool dialog is displayed.
2. Click Open List, and select a coordinate system.
3. Click Set and select a vertical datum from a list of supported datums.
4. Click OK. The generated WKT string can be copied into your files as required.
To convert from one coordinate system to another:
1. On the Tools tab, in the Coordinate System group, click Reprojection. The Projection Tool dialog is displayed.
2. On the left side, do the following:
a. Click Open List, and select a coordinate system.
b. Click Set and select a vertical datum from a list of supported datums.
c. Click OK.
d. Enter the XYZ values, and optionally, the OPK or YPR values.
3. On the right side, do the following:
a. Click Open List, and select the coordinate system you want to project to.
b. Click Set and select a vertical datum from a list of supported datums.
c. Click OK.
4. Click Project . The XYZ, OPK, and YPR fields on the right side are populated with the projected values.
To convert a rotation matrix to OPK and YPR:
1. On the Tools tab, in the Coordinate System group, click Reprojection. The Projection Tool dialog is displayed.
2. On either of the sides, do the following:
a. Click Open List, and select a coordinate system.
b. Click Set and select a vertical datum from a list of supported datums.
c. Click OK.
d. Enter the XYZ and OPK or YPR values.
3. Click Convert :
To convert OPK and YPR to a rotation matrix:
1. On the Tools tab, in the Coordinate System group, click Reprojection. The Projection Tool dialog is displayed.
2. Enter a rotation matrix.
