Overview
PMC Photogrammetry services uses professional-grade drones with the latest capture technologies to deliver the highest quality deliverables in the industry. Our team of FAA-licensed pilots is ready to partner with you for all your drones and sUAS service needs. For every type of project from aerial video, building as-builts, and photogrammetry, PMC is here to help. With optional RTK control, you can have point clouds derived from 2D photos that rival data of conventional laser scanners.
sUAS (Small Unmanned Aerial Systems), also called multi-rotors or drones, are remote- controlled aircraft which are capable of carrying several different reality capture tools. They can access many areas faster and more safely than humans can. PMC has licensed FAA remote pilots who can help capture data in the hardest to reach areas on any project. By eliminating the human risk altogether, PMC can document more information more quickly than ever before, with peace of mind knowing your operations will remain safe. sUAS have a wide variety of applications, including documentation of architectural detail on a building façade, conducting cell tower audits, performing inspections on live power stations, and thermal inspections for leak detection on water & gases.
What is the accuracy of the data that Drones & sUAS produce?
- 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?”
What are the benefits of using Drones & sUAS?
Benefits in Power / Gas / Telecommunications
Safety plays a huge role in these applications because a drone can make it unnecessary for a human to enter a highly dangerous environment where the smallest mistake can cost a life. Using drones, PMC is able to gather the necessary information about your project before getting boots on the ground – from inspecting the condition of cooling towers to looking for gas leaks with an infrared camera, to documenting the serial number on the back of antennas 600’ high.
Benefits in Construction
sUAS offers a wide variety of solutions for the construction industry. For example, tracking the overall progress of your job site that is useful for coordinating material intake or staging different trades on site. Being able to quickly capture and create measurable content is a powerful tool when your environment is changing every day.
Benefits in Architecture
The ornate details on buildings can be quickly documented for identification of repairs and restoration in the tallest features of your project. Having the high-resolution imagery and resulting mesh or point cloud can help replicate the most difficult cornice.
