Draw pixel distribution

Draw pixel distribution command draws a grid into the CAD file that contains all tie point pixels for a camera. The drawing illustrates how well tie points are distributed and points out areas where tie points are missing. Thus, it helps to decide whether the lens distortion can be solved with the current tie points or not.

To draw the tie point distribution:

1. Select Draw pixel distribution command from the File pulldown menu.

This opens the Draw pixel distribution dialog:

draw_pixel_distribution

2. Select a Camera for which you want to see the tie point distribution.

3. Define the number of Columns and Rows of the grid.

4. Click OK.

The grid is shown temporarily at the mouse pointer location.

5. Place the grid in a CAD file view with a data click.

This draws the grid as cell element into the CAD file using the active level and symbology settings.
