Tip 31: Remove Gaps in PhotoModeler ID numbers
We have a short and sweet tip video for you this week. Just 41 seconds! Many objects in PhotoModeler – points, curves, edges, cylinders, surfaces, DSMs, etc. – have unique ID numbers. These numbers are set automatically by PhotoModeler. While working with your project, e.g. referencing points, deleting edges, etc. gaps will form in the […]
Tip 30: Using Sphere Targets and Laser Scan Data
This tip is a follow-on to the Tip 29 blog posting and video. In Tip 29 we showed how the new Sphere Target can be used in PhotoModeler to get precise photogrammetric marking and measurement. Some laser scanners, such as (but limited to) the Faro Focus 3D, can also use sphere targets for scan alignment. […]
Tip 29: Sphere Targets in PhotoModeler
Precise 2d marking of points in photos is key in a photogrammetric project to obtain the highest 3d accuracy. There a number of ways to get this marking precision. The highest precision is obtained when PhotoModeler can use a known target shape for sub-pixel marking. Sub-pixel marking means that the program can detect the position […]
Tip 28: Seeing details in the shadows – PhotoModeler Enhance
This tip video is a milestone for us as it marks our first full year of tip videos, one every two weeks. We trust you like watching them and find them useful. Drop us a line or add a comment below if you have any suggestions for future tips. In this last tip video of […]
Tip 27: Easy Control over Materials and Layers in PhotoModeler
This PhotoModeler tip video demonstrates shortcuts for working with Layers and Materials. Layers are user-defined groupings of objects in your project. Layers can be used to control visibility in the 3D Viewer or to control what parts of the project gets exported. Materials are used to apply colors, surface appearances and textures to the objects […]
Tip 24: Creating 3D Profiles in PhotoModeler
In this tip video we show how to create a 3D profile of a PointMesh in PhotoModeler. A 3D profile is like a contour line but instead of being a line from a set of regularly-spaced heights, it is a single line at any orientation defined by the user. It is the 3D curve that […]
Tip 23: Define which photos texture a mesh in PhotoModeler
In this tip video we show how to define which photographs are used to texture meshes in PhotoModeler. The video first shows how Dense Surface Models (DSM) are, by default, assigned to one photograph for extraction of texture, and how this can lead to un-textured areas. A multi-photo texture material is assigned to the […]
Tip 22: Another way to align a PhotoModeler project with known information
In our last blog post we showed a tip video on how to set up a coordinate system in PhotoModeler from multiple known 3D points using a multi-point transform. With the new EGE (External Geometry Explorer) Add dialog (that was revamped in a recent release), customers have been asking how to set up scale, translate […]
Tip 21: Align a PhotoModeler project to known external 3D points
This video tip demonstrates how to set up a coordinate system in PhotoModeler from multiple known 3D points. This is useful when survey data or geographic data is available and you want the PhotoModeler project to be aligned (same position and rotation) as the external coordinate system. The 3D points can come from a survey, […]
Tip 20: Color and Texture an Imported Point Cloud in PhotoModeler
This tip video demonstrates a technique available in the new PhotoModeler 2012.2 release. If you have a 3D point cloud from a 3D scanner (like a laser scanner) that you would like to match to a digital photo to color the points, PhotoModeler 2012.2 can do that. The 2012.2 release is called the “Laser Scanner […]
