LineVision- Ultimate Introduction The goal of this lab was to use the software LineVision to analyze a video and gather different GPS points from the video. Methods The first task was to find the GPS coordinates of the Green trees in the burn area, the location that was identified for the 3 trees, A, B and C, tree A is in the top left , below it is tree B and below tree B is tree C, the smallest. The gps points of  latitude of 40.449934, and a longitude of -87.050567 for tree A, latitude of 40.449613 and a longitude of -87.050603 for tree B, and a lattitude of 40.449298, and a longitude of -87.049173 for Tree C. Tree A and B are relatively accurate for their GPS locations, but tree C is not as their was an issue with the software that inverted the side of the camera that the location of the point was if it was below the mid-line of the horizontal. Figure 1, This image is a screen capture of the LineVision software, the 3 blue dots represent the tree locations in relat...

Introduction In this lab we were challenged to apply our camera knowledge that we learned from our first lab in a few different real world settings. We were using manual settings on a DJI Mavic Pro 2 to ensure that we had total control over the Images and we got the best results.  Methods First Object The first object that we had to take an image of was a large object in the hanger. We took an image of a white airplane on a white background, which provided a challenge as the exposure was hard to dial in and ensure that the airplanes details would not mix with the floor. We also had a dark colored engine on the airplane that provided a challenge because we wanted to also be able to see the dark details in the engine. We changed the aperture to f 3.3 and a shutter speed of 1/30 and an iso of 100. We used the histogram to help us get these settings because originally the peaks were all off to the left on auto settings, meaning the picture was under exposed so we corrected it by ...

Introduction In the camera settings lab we went thought the process of learning the camera settings with a DJI Mavic pro two. We conducted this lab to ensure that we would be comfortable with changing the camera settings to ensure that we could capture the best data for the given conditions while operating a UAS. We focused on changing the aperture, shutter speed, and the iso. We took note of what happens when each setting is changed and why one would change the settings.  Methods We first took a picture with the auto settings (figure 1) to have something to compare what happens when you change the settings on the drone. In this picture you can notice that the image has a few parts that are over exposed like the windows and the door, but for the most part this is a perfectly fine image. This photo allowed us to get a good baseline for when we changed our other settings so we will refer back to it. Figure 1, Auto Settings F2.8, SS 1/30, iso 100 Aperture   Next we...
