Description
Gets the approximate number of meters covered
by a pixel that is
1 meter away from the camera. This
is commonly multiplied by the distance from the camera to an object
to compute the approximate number of meters covered by a pixel of
the object.Property type

Remarks
Example 1:
Assume PixelSizePerDistance is 0.001.
This means at 1 meter away, the size of a pixel is
0.001 meters. Therefore, the size of 1
pixel at 2,000 meters away is:
2,000 meters * 0.001 (meters / pixel /
meters) = 2 meters/pixel
Example 2:
Assume PixelSizePerDistance is 0.001.
This means at 1 meter away, the size of a pixel is
0.001 meters. The diameter, in pixels, of a sphere
2,000 meters away that has a diameter of 10 meters
is:
10 meters / (2,000 meters *
0.001 (meters / pixel / meters)) = 5
pixels
PixelSizePerDistance is accurate for a pixel in the
center of the window. Accuracy decreases slightly the farther off
center a pixel is and the wider the camera's field of view is.
