Using PhotoModeler with Rhino 3D
Rhino® is a popular CAD and 3D modeling application used in many fields. PhotoModeler is a popular photogrammetry program for measuring and modeling the real world using a camera. A PhotoModeler project can be exported in the Rhino 3dm file format and further processed, or be used as the foundation for other work using Rhino’s […]
New Method for Measuring Movement in Security and Surveillance Video
When you have a sequence of images containing data/evidence spread over several frames recorded from the same position, for example, a series of frames from a fixed security camera, you can use PhotoModeler’s image sequence feature to measure or track objects in the scene over time! Here are some possible uses: Calculating and comparing the […]
The Other Photogrammetry Automation – Coded Targets
What are Coded Targets? Automation History Why Use Coded Targets? Coded Targets vs Smart Points Coded Target Examples and Applications What are Coded Targets? I am sure you’ve seen a bar code on product packaging. Bar codes are scanned by a laser that reads the pattern of white and black bars, and converts that into […]
Can Measurements be Made from Law Enforcement Body-Worn Camera Video?
This is a guest blog post written by collision instructor, and active LE officer, Bobby J. Mullinax. See bio below. Why Use Body-Worn Camera Video for Measurements? Photogrammetry is a technique that uses images and photos to obtain accurate 2D and 3D measurements and diagrams of the real world. A body-worn camera stores a video that […]
Forensic Photogrammetry: A Case Study
This is a guest article by forensic imaging consultant Mike Mayda. Bio below. Why Use Photogrammetry in Forensics? Photogrammetry can be a very powerful tool in forensic analysis. It is often useful to have an accurate 3D reconstruction of an accident or crime scene, especially in cases where position, distance, and perspective are important. Given […]
How to Digitize Templates and Patterns With a Camera
In a number of industries, measurements are made of objects and equipment in the field, and then materials are manufactured to fit those existing objects. Some common industries like this are kitchen counter tops, boat covers, enclosures, or flooring, wall cladding, and stairway coverings or lifts. A common approach within these industries is to create […]
With a Camera Measure Shape and Movement in Sails and Flexible Structures
With A Camera Blog Series In our second of the series we describe a unique and interesting application of measuring fabrics, sails, and flexible structures – something that is very hard to do with other methods. Introduction Flexible structures, such as sails, fabrics, flexible wings, and solar sails are very hard to measure […]
With a Camera Determine Who Caused a Collision
A New Blog Series We introduce a new blog series called “With A Camera“. With each blog post in this new series we describe an application of close range photogrammetry – that is, 3D measurement and modeling with a camera. The articles will describe significant real-world problems and how photogrammetry was able to uniquely solve […]
Using a Dropcam for Forensics and 3D Measurement
The Dropcam security camera is one of several easy-to-use IP cameras on the market for self-monitoring security systems. This article describes a forensic simulation using Dropcam imagery, and the 3D-from-photos software, PhotoModeler. PhotoModeler is the most comprehensive solution, at any price, for working with images from a variety of sources to produce accurate 3D measurements […]
UAS / UAV Photography for 3D Scanning, Measurement and Modeling
With the proliferation of UAS/UAV (unmanned aircraft systems, unmanned aerial vehicles, or drones) armed with lightweight cameras it has become much easier to capture, scan, measure and 3D model scenes from above. The technique is called photogrammetry. You no longer need to hire an airplane to take aerial photos or purchase expensive aerial photos of […]
