PhotoModeler At Upcoming Trade Shows

Posted on Tuesday, April 12th, 2016

PhotoModeler at WREX and ARC-CSI 2016 conferences Come join us at the PhotoModeler area at both the WREX 2016 World Reconstruction Exposition, May 2-6 in Orlando, FL ( and the ARC-CSI Crash Conference, May 23-26 in Clark County, NV ( Accident reconstructionists can consult with our experts about best practices for the use of PhotoModeler in collision investigations. Topics include incident scene mapping from UAS/drone, combining photogrammetric data with other survey devices like total station or laser scanner, standalone use of PhotoModeler for scene surveys, using 3rd party photos from unknown cameras, and presenting photogrammetric evidence in court.    

PhotoModeler 2016.0.6 Release

Posted on Tuesday, March 29th, 2016

2016.0 PhotoModeler 2016.0.6 was released Mar. 24th, 2016. The main reason for this release was to improve stability and fix user-reported crashes and problems. There were 9 crash fixes, 5 fixes to non-crash items and 7 small improvements. We have found that PhotoModeler 2016’s new crash reporting tool (that sends data to us in the event of a crash) is helping us track down some of the rare and esoteric crashes. It is almost impossible to fix a bug if we can’t reproduce it here and the new crash reporting tool helps us do that. It is not perfect, but we do like how it has helped improve the stability of PhotoModeler for our customers. One of the crashes that…Read More

PhotoModeler 2016.0.5 Release

Posted on Tuesday, February 16th, 2016

2016.0 PhotoModeler 2016.0.5 was released Feb. 16th, 2016. The main reason for this release was to improve stability and fix user reported crashes and problems. There were 10 crash fixes, 4 fixes to non-crash items and 4 small improvements.   Getting the New Release If you are a current customer and have an active maintenance subscription, get the update. You can also use Check for Updates within the PhotoModeler software. If you are new to PhotoModeler and would like to evaluate the new version, download it. You will have 10 days of full capability (load your own photos, export models, etc.). After 10 days it switches to a restricted Demo mode – and extension codes are available from PhotoModeler resellers.

PhotoModeler 2016.0 Release

Posted on Wednesday, January 27th, 2016

2016.0 PhotoModeler 2016.0.4 was released Jan. 27th, 2016 after a year of intense development and a couple of months of beta testing. One of the main focuses of this release is improved results with drone / UAS / UAV projects. The software is much faster processing larger numbers of photographs, handles control points with more flexibility, and reads GPS data from drone image headers. The improvements will help many different types of large projects in PhotoModeler Scanner (not just drone projects). As well there are numerous other changes that impact all three versions of the software. The major improvements are: New Smart Project Robust Orient. The photo orientation algorithm used in Smart Projects has undergone a complete rewrite. The major…Read More

Tip 86: Reusing camera positions with replaced images

Posted on Wednesday, September 30th, 2015

When two or more cameras, affixed in un-moving positions, are used in a project, the images taken by these cameras can be replaced in the project without having to re-orient them. Doing this can save time and effort for project setups or camera rigs that are reused repeatedly. This procedure of swapping images on fixed cameras is useful for… setting up repeatable measurement projects using a fixed multi-camera rig as shown at right, doing comparisons between data sets while minimizing variables, measuring movement over time from a set of fixed cameras positions (e.g. security cameras), and creating multiple photo textures where lighting is variable. These projects can be oriented with SmartMatch, Coded Targets or manually marked and referenced points. The first object…Read More

The New PhotoModeler Ambassador and Grant Programs

Posted on Monday, September 21st, 2015

Eos Systems is introducing two new community programs: PhotoModeler Ambassadors and PhotoModeler Grants. PhotoModeler Ambassadors A PhotoModeler Ambassador is a keen member of the PhotoModeler community that regularly uses PhotoModeler and photogrammetric processes in their work, and regularly shares information, using various media, about their experiences with colleagues and the community. Ambassadors receive recognition in a number of ways, including being listed on the PhotoModeler Ambassador web page: PhotoModeler Grants A PhotoModeler Grant is a discount on PhotoModeler software and maintenance for educational institutions and students (as well as the occasional indie film or game producer). To obtain the grant the student / professor / producer submits a grant application. Eos staff will review these applications on a case-by-case basis…Read More

Tip 85: Measuring suspect height using a single photo from an unknown camera

Posted on Tuesday, September 1st, 2015

Surveillance cameras are ubiquitous in public places. Crimes and/or the suspects participating in them are often captured on one or more of these cameras. Measuring the height of a suspect in a scene is usually a key piece of evidence in identifying the individual. PhotoModeler can be used to accurately measure the height of a suspect in a single image from an unknown camera. The example shown in this tip is a simulation of a crime scene where the suspect’s height needs to be measured. Since the source of the image is unknown, PhotoModeler needs to ‘solve’ the camera’s parameters (e.g. focal length), using some known information about the scene. In PhotoModeler, this is called the “Inverse Camera” feature. The investigator…Read More

Tip 84: Preconfigured Layers and Materials in New Projects

Posted on Wednesday, July 29th, 2015

Do you find yourself adding the same layers and/or materials to each of your new PhotoModeler projects? Or do you need a way to organize most of your PhotoModeler projects the same way – so that you can more easily separate or group items and display them in isolation? If yes, or if you don’t already know about Materials and Layers and their ‘profiles’ then this tip will be of interest to you. Layers and Materials can be manually added to a project easily, but pre-configured layers and materials can be added to all new projects, automatically! First, some background on layers and materials: Layers:  Much like ‘layers’ in other CAD and graphics software packages, PhotoModeler Layers provide a means…Read More

Tip 83: Using 3D Light Rays for Photogrammetric Project Assessment

Posted on Monday, June 29th, 2015

PhotoModeler has an interesting photogrammetry visualization tool for assessing the geometry and the structure of a 3D solution. This tool is called “Rays” – short for ‘visualized light rays’. A light ray is shown in the 3D View as a solid white line and portrays the vector that light would have traveled from the point in the scene to the camera that imaged it. In this way, the light ray in the 3D View shows how the points in the 3D model and the individual camera positions (where photographs were taken) are related. The camera station symbol in the 3D View (blue block with green lens) depicts the position and orientation of the camera when each photograph was taken. The Rays…Read More

Tip 82: Use Point Auto-detect to quickly mark imported points on photos

Posted on Thursday, May 28th, 2015

A recent update added the ability to use Point Auto-detect for Control point marking and Multi-point Transform point marking (in addition to regular point marking as described in this blog post). This tool can help speed up marking and referencing, with the right kind of project and photos. External data is sometimes used to set up a coordinate system or help with the solution.  The external data is from a survey, from GPS, or some other measurement tool. The typical process for using this data is: import the 3D data (typically from a file), associate the 3D data points with points in the PhotoModeler project, and use this information to form a coordinate system transform (non-warping), or use this information to…Read More
