Top PhotoModeler Videos for Learning

Posted on Monday, October 30th, 2017

Instructional tutorial videos are a great way to learn PhotoModeler.  We’ve recently done a few updates to the PhotoModeler tutorials: A new forensics single camera tutorial Some new voice overs Key videos on YouTube Newest Tutorial Video for Forensics We recently published a new tutorial that will be of interest to those doing forensic measurement from single images (esp. those taken by security cameras and dash-cams). A recent release of PhotoModeler added an improved way to compensate for lens distortion for the highest accuracy results – this video describes this process. This tutorial describes how to extract important measurements like heights and positions in a crime scene from a security or surveillance camera image. [Single Security Camera Tutorial Video –…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

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

PhotoModeler 2015.1.1 Release: more improvements!

Posted on Wednesday, May 6th, 2015

PhotoModeler, PhotoModeler Scanner and PhotoModeler Motion have a new release: version 2015.1.1 – release date May 4, 2015. This update has some useful new features, several customer requested changes, and some fixes.     The two most significant changes are: 1. New EGE point marking and assignment modes: The various point marking/assignment modes are now more unified in the EGE (External Geometry Explorer – handler of imported 3D data). As well, Point Auto-detect can now be used to mark control points and multi-point transform points on photos (in Scanner and Motion). Whether control, multi-point transform, or pinned points are imported, the marking and assignment process is the same: select a point in the EGE and use the appropriate tool to mark/assign the point (or auto-detect…Read More

Tip 81: Change the image list thumbnail size in PhotoModeler

Posted on Monday, April 27th, 2015

Have you ever wanted to increase the size of your thumbnail (or ‘chip’) images, in the PhotoModeler Photo List? It is possible to change the size via Preferences, but now it’s quicker, easier and more flexible: just use the + or – buttons on the Photo List toolbar! The Photo List in PhotoModeler provides a handy way to review photos and open or show properties of one or more of them. Sometimes it’s good to show a bunch of small thumbnails, while other times, bigger thumbnails showing more detail, is preferable. Having them adjustable on the fly is time saving. The thumbnail images are cached on disc, which means once a size is created it is stored. Switching to a cached thumbnail size is almost…Read More

Tip 80: Arranging your photos while referencing

Posted on Monday, April 13th, 2015

While many aspects of PhotoModeler are automated, there are still times we need to use the manual point marking and referencing mode. This tip describes a method used in manual point referencing for arranging the photo windows different. It is called ‘Auto-arrange Photos’. When manually referencing points, it helps to open a number of photos in order to choose photos for point marking/referencing. Often, however, when it comes time to mark/select points while Referencing, maximizing screen real estate for the ‘source’ and ‘destination’ photos will help assure it’s done accurately. In addition, a more regimented system of window positions and stepping through photos can help keep track of the process. The latest tip video shows how the Auto-arrange Photos tool is used to automatically arrange…Read More
