Tip 66: Interesting Ways to Set PhotoModeler’s 3D View

Posted on Monday, July 21st, 2014

Tip 66 3D Viewer Screen

PhotoModeler’s 3D View window has controls for manipulating the view position. This allows you to rotate around the 3d model, zoom in and out, or pan. The buttons in the bottom right corner of the 3D View provide this user interactive dynamic control of the view. You move the mouse cursor over one of the…Read More

PhotoModeler Orthophoto Improvements & 2014.1 Release

Posted on Friday, July 11th, 2014

2014.1 Orthophoto Blending

A new version of PhotoModeler¬†(2014.1) was released July 9th. The main focus of this release is improved orthophoto production – in quality, speed and capability. An orthophoto is a re-rendering of photographic data to take into account the surface shape.¬† It turns a photograph (or set of photographs) into an image that is like an…Read More

Tip 65 Tutorial Screen

There are a number of very useful resources available to assist with learning PhotoModeler (whether it is first time use or an expert learning about a new feature). This tip video outlines a number of these resources and how to access them. Some of the resources described are: the tutorial summary dialog that opens at…Read More

Tip 64: Relating Camera Stations and Photos in PhotoModeler

Posted on Tuesday, June 24th, 2014

Screen shot of tip 64 video

In PhotoModeler a Camera takes a Photo. The location and orientation of the Camera in space when the Photo was taken is called a Camera Station. Photos and Camera Stations are central concepts in PhotoModeler and photogrammetry. There is a one-to-one relationship between a Photo and a Camera Station. In the PhotoModeler user interface Camera…Read More

Tip 63: Two Styles of Surface Drawing in PhotoModeler

Posted on Monday, June 9th, 2014


PhotoModeler’s Surface Draw is a useful tool for doing 3d ‘tracing’ on a surface in a single photo. Typically in photogrammetry to create a 3D point one needs to mark or identify the image of that point in two or more photos – so it can be computed by triangulation/intersection. There are a couple of…Read More

Tip 62: Forensic Modeling of Trajectories with Photogrammetry

Posted on Friday, May 30th, 2014


A common forensic task is to determine the position of a shooter in a crime scene. One technique uses bullet trajectory rods and calculations of intersection and extension. Photogrammetry, the science of performing measurements from photos, can be used to model the cylindrical trajectory rods, using a normal DSLR camera, and find their position and…Read More

Tip 61: Using Un-calibrated Cameras in Photogrammetry

Posted on Monday, May 12th, 2014


Photos taken with a calibrated camera provide the best results in photogrammetry and PhotoModeler.¬†Camera calibration is the process of determining accurate specifications for the camera’s internals – such as focal length, format size and lens distortion. What are the options when the camera is not, or cannot be calibrated? PhotoModeler can handle a uncalibrated camera…Read More

Tip 60: Varying the detail level in a PhotoModeler PointMesh

Posted on Monday, April 28th, 2014

Tip 60 Screen

PhotoModeler Scanner’s MVS and Pair-based DSM tools create dense point clouds. These 3D points are usually ‘triangulated’ to produce a useful surface. This tip describes a key setting used in this triangulation process. Triangulation is the process of converting a 3D point cloud into a triangulated 3D surface that can be used for surface study,…Read More

Tip 59: Tricks for Using Tabbed Windows in PhotoModeler

Posted on Monday, April 14th, 2014

Tip 59 screen

A close range photogrammetry program like PhotoModeler presents different types of information to the user such as photos, 3d views, and tabular data. In PhotoModeler, data is presented in separate windows that can be sized and moved around the display area for maximum flexibility. A modern tabbed interface allows easy access to a number of…Read More

Tip 58: Denser Meshes in PhotoModeler’s MVS with a 2 Photo Min

Posted on Monday, March 31st, 2014

Tip 59 screen

‘Multi-View Stereo’ is the new Dense Surface Model extraction algorithm introduced to PhotoModeler Scanner a few months ago. The ‘multi’ part of the name refers to the multiple photographs used to extract and confirm matching data. MVS and DSM are methods in photogrammetry for extracting a 3D point cloud (like a laser scanner) of a…Read More
