Drone technology is pivotal in our Reality Capture process.

  • PMC utilizes the latest state-of-the-art sUAS equipment to deliver the best results. Our equipment utilizes survey grade RTK corrections (GPS) data so you can expect to see accuracy of +-2CM across a large project.
  • The data may comprise a few dozen or even several thousand high-resolution pictures. Photogrammetry software stitches all the images together into one 3D representation of the subject. This process creates a high definition point cloud, much like what you would expect from a terrestrial laser scanner, just not as dense. This is especially useful on projects that include areas like roofs and towers which a terrestrial laser scanner can not reach.
  •  Why does this matter? Being able to capture areas up high and out of sight with sUAS is much safer than traditional methods, which might include climbing with some sort of measuring apparatus like a tape measure or a laser disto-meter. These methods typically introduce error as the risks of getting to the area of interest are very high. Eliminating the need for humans to climb to the area of interest eliminates a large amount of the overall cost as well, because typically the climb to the top of a cell tower takes longer than the actual work to perform. You have to ask yourself, “Do I need to send a person up, or can I gather all the information that I need from high-definition imagery consolidated into a highly accurate point cloud, which can be measured and inspected as though I were right there?”
