Surface Draw - fixing a wrong surface

This video shows what happens when Surface Draw is place on the wrong surface (here outlining areas of boat decking), and how to fix it by assigning the correct surface. Surface Draw points, lines, or curves, assigned to a surface in PhotoModeler that does not match the true real-world surface will not calculate in the correct 3D position. This means, when they are viewed from on photos from other angles, their positions will not line-up and match. To fix this, the correct surface is assigned to the points and the correct 3D position are automatically calculated.

Troubleshooting high residuals

High mark residuals are often caused by incorrect references. This video outlines a way to find incorrect references in a manually marked PhotoModeler project.

Turning off auto-advance during referencing

During referencing mode the active reference point with-in the selected source points can automatically advance to the next point and will be reset to the start when you move to another destination photo. If you prefer to reference between several photos at once you can turn off auto-advance and manually control when the source point switches.

There are several ways to use known XYZ point data with in PhotoModeler. This video covers the two main uses, multipoint transforms and control points.

Using lines to mark hidden corners

When a corner is hidden due to an occlusion you can use temporary lines to estimate where the corner lies.

Using multiple frames from a static camera position

If a camera(s) position remains fix and you would like to use multiple frames from this position you can replace the image data without needing to re-orient the photos. This can be useful when trying to obtain measurements from a security camera or when using a fixed camera set-up to measure a dynamic scene.
