The Professional’s Choice for Measuring and Modeling the Real-World.

Crush Measurement

• Use unknown photos to model vehicle crush and compare to an exemplar vehicle - all within PhotoModeler! • Perform difficult measurements in PhotoModeler or export profiles to a CAD program

Crushed vehicle project using unknown photos.

Skid Mark Mapping • Map and measure skid and road marks • Use single photos if you have some known 3D control points from the original scene • Use constraints (known relationship data, such as lengths, parallel lines) to strengthen the project • Export birds-eye-view images of skid marks or other surfaces • Works even if all your photos are taken from ground level!

3D Modeling

• Use your own camera to create detailed models of vehicles and other objects for court animations • Map phototextures from photos on to your model for a realistic result • View or measure in PhotoModeler, or export to CAD, animation and rendering programs • Model crime scenes for measurement, analysis, and documentation • Survey complex scenes Crime scene measurement project. Photo-textured 3D model for realistic presentations.

PhotoModeler Pro is an award-winning Windows software package used by professionals worldwide to generate measurements and maps from photographs.

How does PhotoModeler work? Load photographs into PhotoModeler • Shoot or obtain two or more overlapping photographs from different angles of an object or scene using any type of camera. • Scan the pictures into digital form and import them into your PhotoModeler project: for digital cameras, download straight to the computer’s hard-drive; for film cameras, use a film scanner; and for video cameras, use a digitizer board. • If you have one or more photographs from unknown sources, use Inverse Camera (with sufficient known control points) or Object Constraints to help rebuild camera information.

Mark and reference the photographs • Using the Point, Line, and Edge tools, mark on the photographs the features you want in the final 3D model. • Use the image zoom function to increase the precision and ease of marking. • Use the Referencing functions to tell PhotoModeler which points on different photographs represent the same location on the object or in the scene. • For projects using photos from unknown sources, enter known information such as control points and constraints.

Process the information • Press the “Process” button and sit back for a minute while PhotoModeler processes your input data. • PhotoModeler produces an accurate 3D model by using an advanced algorithm that adjusts input data, creates 3D point data, and minimizes errors.

View and export the 3D model • • • •

View and measure the results in PhotoModeler’s advanced 3D Viewer. Display accurate coordinate, distance and area measurements. View and manipulate the xyz coordinates in the Point Table. Export to your favourite rendering, animation, or CAD program to complete your court presentation materials. • Export photo-derived textures with 3D Studio, OBJ, VRML, and DirectX formats. • Continue on by adding more photographs, more points, lines, and edges, and or by using the advanced marking tools to model NURBS Curves, Cylinders, Surfaces and Surface Draw.

How accurate is PhotoModeler?

How long does it take?

The accuracy of a final PhotoModeler measurement depends on a number of factors: the resolution and number of photographs, the angles between the photographs, the number of referenced points, and the quality of the camera description. PhotoModeler’s accuracy ranges from 1 in 200 for low resolution photographs (e.g. for a six foot object, measurements will be within a third of an inch), to 1 in 8000 for high resolution photographs (for the same six foot object, within one one hundredth of an inch). For projects requiring high accuracy, PhotoModeler has tools for obtaining up to 1 part in 25,000 and higher accuracy!

The time needed to complete a set of measurements and produce a model depends on the complexity of the project, the type of camera used, and the speed of the computer running PhotoModeler. A very simple project might take 10 minutes whereas a very detailed and complex scene might take a day.

Advanced Features Measurements · Perform point, distance, length and area measurements right within PhotoModeler. Single Photograph Support · Use Inverse Camera (with sufficient known control points) or Object Constraints to model from a single photo. This opens up the use of photographs from historical archives, bystanders, and third-parties for producing 3D data. Control Points and Perspective Matching · Enter known 3D point locations into PhotoModeler and accurate camera positions and angles are generated automatically. Improve camera geometry or match a camera to a perspective photograph for a rendering program. 3D Viewer · View and rotate complex projects and fully textured models. Camera Calibrator Program · Accurately measure your camera’s focal length, principal point, digitizing aspect ratio and lens distortion. Texture Extraction and Ortho-Photos · Extract images from surfaces by removing any perspective and shape distortions and use them as texture maps in rendering programs or export as orthographic photo-maps. Surface Drawing · Points can be marked on a known surface in one oriented photograph and the 3D point locations will be computed.

Constraints · Enter known relationships into the project (eg. parallel, perpendicular, colinear, etc) to fine-tune processing. Project Merge · Combine two or more PhotoModeler projects into a single project. Surface Tools · Add surfaces to features defined by Points, Lines, Curves, and Edges. Surfaces can then be assigned photo-textures and colors. Sub-pixel Target Marking · High accuracy capability with circular targets. Edge Modeling · Model linear features across photos even when no distinct end points are shared across the photos. NURBS Curve Modeling · High-quality Non-Uniform Rational B-Splines provide great modeling capabilities for objects / scenes with curved edges. Cylinder Modeling · Model and measure cylindrical shaped objects such as pipes and pillars. Automated Tools for Surface Models · Automated Marking, Automated Referencing, and Automatic Surfacing aid in high-density surface model creation. Plus much, much more!
