Unlike the many tool-specific courses offered by the many vendors in the laser scanning space, the Forensic Photogrammetric Analysis course that I've been teaching for a while now focusses on the science of measurement as well as best practices that will help arrive at valid conclusions.
Here's a bit of a sample of what we're on about this week...
A few months ago, I wrote about calculating Nominal Resolution during the content triage stage of the image / video processing workflow. That critical process depends upon an accurate measurement of the distance from the camera to the object of interest. Who's responsibility is recording this measurement? Did you collect the video from the crime scene / witness location? If you did, did you roll out your tape measure or use your roller measuring wheel? If not, why not?
If not, might it be due to a lack of knowledge about the importance of calculating the nominal resolution? Perhaps you simply don't have the right kit.
You can buy your tools from a dedicated forensic science / crime scene vendor like Sirchie. Or, you can head over to your local home improvement store. At Home Depot, you can get a 300' measuring tape for under $40.
This Lufkin measuring tape is currently $38. A similar measuring tape from Sirchie is almost $80.
The Lufkin measuring wheel at Home Depot is less than $35. A similar model at Sirchie is over $70.
The point?
It doesn't have to break the bank to perform measurements at scenes that will later inform measurements within your images and videos.
If you'd like to know more, or if you'd like to sign up for our next class this fall, head over to our training page and see what's on offer. I hope to see you in class soon.
