Creation of SketchUp Model with the Use of Trimble Vision

The enthusiast may remember that in 2003, Trimble represented a super-camera – V10 Imaging Rover that takes images of large objects, something like building, bridges and roads. It captures as well as accumulates pictures of mega-objects – bridges, buildings, apartments – tag those site, which are deck up with those photograph with specific locations and orientation.

Trimble Vision Total Stations are gathering the images – some people are wondering about geospatial professionals might use this location-aware data to create 3D models in SketchUp.

The latest versions of SketchUp Pro and Trimble Business Center now work together to export images and camera poses for the direct use with SketchUp’s Match Photo tool.

Trimble V10 Imaging Rover: The Trimble V10 Imaging Rover with Trimble VISION™ technology is an integrated camera system that accurately captures 360-degree digital panoramas for well-organized visual documentation and dimension of the surrounding environment. As a complete system solution, the Trimble V10 enables you to capture more critical information that can be transformed into enhanced, rich geospatial deliverables. With the Trimble V10, a picture is worth a thousand points.

Total Stations: The precision optics and robotics of Trimble total stations are paired with streamlined workflows, innovative training and in-field support services. With the performance to maximize productivity today, and the scalability to continue adapting to new challenges and opportunities into the future, surveyors around the world trust Trimble optical solutions.

Match Photo introduction: Use the Match New Photo and Edit Matched Photo menu items to create a 3D model to match a photo or to match an existing 3D model to a photo's context. Activate the Match New Photo and Edit Matched Photo menu items from the Camera menu.

Trimble has made this mixing along with improvements to Match Photo to make this kind of photo modeling easier than ever before. There is no need to designate vanishing lines and prominent features on the structure to specify each camera pose. The camera orientations here are pre-loaded with the file import from Trimble Business Center (TBC). With as few as three points exported from TBC you can set up your axes and begin to create your model.

For working in a rhythmic way, Trimble expanded the TBC *.skp exporter to permit images and points to be included. This lets you influence the TBC’s skill to create photo points with precise locations. You can generate and export any key points that will assist the modeling process within SketchUp, including points for setting up your SketchUp axes and inference points for important architectural particulars.

The Trimble V10 comprises of a panoramic camera display. This means there are twelve cameras that collect images for a full 360-degree view. The multiple viewpoints are useful while you are processing the images in TBC, since you can generate tie points all the way around each of the photo stations to be used in the bundle modification.

For the modelling in SketchUp, the users only require to export images that include the area of interest (e.g. building, bridge …). In TBC, you can easily create a polygon boundary around the area of interest. If you use a boundary, the *.skp exporter will include only the images with view angles that intersect it. This greatly reduces image clutter in SketchUp.

To further help filter out unnecessary images from the exported *.skp, TBC let users to include a subset of your photo stations. This lets you select only those stations, which have images; you need for modeling in SketchUp. The *.skp that TBC creates during export contains a divide the sight tab for each image. This diminishes confusion and provides easy navigation during modelling.

Since the capability to move easily between images is important to efficient model creation, the “Igloo view” (keyboard shortcut “i”) has been improved to walk you through the images fast. You can see the adjacent images that provide context around the arrangement.

After exporting appropriate 3D points to SketchUp, their positions can be matched with pixels in the images, to orient the coordinate axes. If the structure is rectangular, this should only need to be done with one image using a few points, and then all of the images will be automatically oriented in such a way that a consistent model can be created from multiple images.

The images from TBC have the camera distortions removed, so they are also great for texturing users model in SketchUp. But make sure to collect the images from locations that allow for a clear view of the structure (without obstructions like cars or trees), then use the Project Photo tool to apply them as textures.

After completion of these tasks, the users will have a model that can be used in all sorts of SketchUp workflows, including daylight, shadow, and view plane analyses, report generation, and Google Earth previews.
