Hey guys. The Ballistics team finally got a lead to work on. We now have an idea on what to go about doing. For the past week I’d say it was mostly focused on familiarizing yourself with the concepts of the characteristics of fired bullets, guns, and the scanning procedure as this information is fundamental to the algorithms we’re going to becoming up with in regards to determining what constitutes a good scan of a bullet and what doesn’t. Now our goal is to open the X3P, C++, etc. files on our computer so we can get an understanding of the pre-made C++ library for bullet scans created a couple of years ago. It is then that we will be able to use them to determine the number of missing values in a scan. Missing values occur when the light emitted by the scanner does not reach all the way down to the base of the bullet (the bullet is not completely round since it has high levels, low levels, and ridges). The anatomy of a bullet is complex. I might post a picture of one in the future. Anyways, there are many reasons the light does not go all the way down and being able to quantify what those reasons could be and have a program judge them requires very careful deliberation. The next step would be to calculate the number of missing values relative to the total number of values in the scan which would give us a percentage. Then we can use that percentage and establish a threshold for what percentage of missing values can there be before it stops being a good scan. But that’s later on.
That’s all for now guys…Hope the explanation was clear.
