Let's Talk About It
Photogrammetry is the science of making measurements from photographs, and using those measurements to create hyper-realistic/accurate depictions of the subject.
I do a fair amount of pro bono work under my non-profit, Actual Innocence Review (www.airtexas.org), and I recently had an opportunity to use photogrammetry. The experience was exhaustive and exhausting, but turned out to provide the information I needed to prove my client’s innocence. By creating an accurate 3D map of the crime scene, I was able to demonstrate that the primary witness against my client couldn’t possibly have seen what she claimed.
There are basically two types of photogrammetry, aerial and terrestrial (close-range), and both can be combined to assist with criminal cases. Photogrammetry has been used for years to recreate crime scenes, to include traffic accidents, but the technology has improved significantly, even in the last ten years. Due to the expense of the laser positioning equipment and whatnot, photogrammetry has almost exclusively been a tool of the state, but affordable new software programs are making it available to everyone.
As with any process claiming to be “science,” photogrammetry has and will continue to face challenges. For example, where do you find an “expert” in this field? I can suggest the American Society for Photogrammetry and Remote Sensing (www.asprs.org), but you can also give a free software program called Tinkercad a shot. If you want to really nail it, you can invest in a program called Photomodeler.
Add this capability to your defense arsenal, and get better results for your clients.
