PhotoModeler is a software application that performs image-based modeling and close range photogrammetry – producing 3D models and measurements from photography.

Close Range Photogrammetry (CRP) is a sub-set of photogrammetry and is differentiated from Aerial Photogrammetry by the type of input photographs. In CRP, photographs are taken from the ground, or from aerial positions that are at a closer range to the subject than typical Aerial Photogrammetry.[1][2] PhotoModeler and CRP are used for performing measurement and modeling in archaeology, architecture, biology, engineering, film production, forensics, and mining.[3][4][5] PhotoModeler, first publicly released in 1993, was the first commercial all-digital close-range photogrammetry and image-based-modeling system.[6]


The PhotoModeler product line currently consists of the base PhotoModeler product, the PhotoModeler Scanner product, and the PhotoModeler Motion product.


PhotoModeler creates accurate 3D models (consisting of Points, Lines, Curves, Edges, Cylinders, Surfaces, NURBS, and Shapes), and accurate 3D measurements from photographs taken with most standard cameras (either digital or film). 3D models can be created and exported with photographic textures extracted from the original photographs. Automation is available with coded targets (special 'barcode-like' circular targets placed in the scene before photography).

PhotoModeler Scanner is a super-set of PhotoModeler and includes all its features – it adds SmartMatch (automated feature detection and matching on photos), and DSM (dense surface modeling).

PhotoModeler Motion is a super-set of PhotoModeler Scanner and includes all its features – it adds capturing geometry over time (4D measurement = 3D + time).

File formats[edit]

PhotoModeler has the ability to read the following image formats: JPEG (.jpg), Tiff (.tif), Windows BMP (.bmp), PC Paintbrush (.pcx), Targa (.tga), Portable Network Graphics (.png), Pict (.pct), Photoshop (.psd), Portable Pixmap (.ppm), Macintosh Paint (.mac), EA Interchange File Format (.iff), CALS Raster (.cal), PhotoCD (.pcd), Silicon Graphics Image (.sgi), Silicon Graphics RGB (.rgb), Jpeg2000 (.jp2/.jpx), MS HDphoto (.hpd/.wdp).

PhotoModeler can import 3D data for comparison, matching, and as control points in the solution. The input file formats accepted are: DXF, Wavefront OBJ, 3D Studio 3DS, and Raw Text files.

PhotoModeler exports 3D data to the following formats (some with mapped photographic textures): 3ds, Rhino 3DM, DXF, Filmbox FBX, IGES, Google Earth, Maya Script, 3D Studio Max Script, Wavefront OBJ, Raw, and VRML.


Some of the applications of PhotoModeler are:

  • Accident reconstruction / Forensics[7]
  • Archaeology / Paleontology[8]
  • Architecture
  • Biology[9][10]
  • Engineering[11][12]
  • Film[13]
  • Mining[14]
  • Situational Awareness (SA)[15]


Development was started in 1990 by Alan Walford. The first public release was a beta in October 1993.

The direct alternatives to PhotoModeler are: Pixdim, RhinoPhoto, iWitness, and Elcovision.

CRP software for doing automated high-accuracy industrial measurement is GSI’s VStars.

Alternatives that carry out dense automated modeling similar to the PhotoModeler Scanner product are: AdamTech 3DM, Topcon Imagemaster, and Autodesk’s 123D Catch.

PhotoModeler is occasionally used with aerial photography (more so from low flying craft like remote helicopters, drones, etc.) but for full aerial photogrammetry capability an alternate package such as SOCET SET, or LPS (Leica Photogrammetry Suite) is suggested.
