Team Vision for Problem Definition Phase
- The end goal of this project is to develop a working sensor mount for use on a multi-rotor drone. The design of the mount has to allow for stabilization of multispectral images via a gimbal system.
- The goal of the problem definition is to establish a solid foundation for the project. Key aspects of this foundation include relevant research and benchmarking, identifying project goals and deliverables, creating engineering requirements in line with the needs of the customer, and a concrete project plan.
Project SummaryTraditionally, archaeologists use satellite imagery from the government to provide maps of their site. However, RGB images from these satellites don’t always provide the information that archaeologists are after. A cost-effective solution is to put multiple types of imaging sensors on an unmanned aerial system (UAS). These sensors should include multispectral (including RGB and near-IR) and far-infrared (FIR) sensors. The multispectral and infrared cameras, when used together, can detect chlorophyll which can help determine the health of vegetation in an area. If plants in an area are not healthy, it can serve as an indicator that a man-made structure lies underneath. Moreover, the FIR camera can provide information about thermal anomalies lying under the earth, further signifying to the archaeologist that there may be something of interest under the earth.
The main goals of this project are to come up with a fully integrated system with multiple imaging sensors that detect many different wavelengths of light, keep the system small enough so that it can be easily transported, and provide enough “fly-time” for an archaeologist to collect the data that he or she needs. The expected result is a functional prototype which can be used by professionals to determine the locations of unknown subterranean features. The resulting design and prototype needs to be delivered on-time, within the specified budget, and tested in a manner that complies with FAA regulations.
