Photogrammetry 101

Photogrammetry 101 provides a basic introduction to the subject, allowing anyone with little or no technical knowledge to begin their exploration of photogrammetry. It covers such topics as how to do an offline survey, the triangulation principle, and some of the challenges of doing photogrammetry. Triangulation principle Photogrammetry is a form of coordinate measurement that uses triangulation to calculate the position of a point. It primarily involves measuring and interpreting photographs and energy patterns in digital format. The process can be used for various applications, including 3D modeling, geographic databases, and other purposes. A well-planned photogrammetric survey can provide accurate, reliable information about a site or environment. However, many factors must be considered to achieve optimum results. For example, a trade-off must be made between the number of photos and their accuracy. A well-planned survey also has to consider any blockage that might occur along the

Drones Certificated Remote Pilots

  Drones Certificated Remote Pilots must know how to pilot a drone safely. This includes learning to operate the device, land it, and take off. There are also specific requirements for commercial and recurrent drone operations. Qualifications to become a drone pilot It is a good idea to get specialized training if you plan to become a drone pilot. There are several high-quality training options available at a reasonable price. In addition to technical training, consider joining a community-based organization like the Academy of Model Aeronautics. Registering for a remote pilot certificate is one way to get your feet wet. A remote pilot certificate allows you to fly a drone for recreation or enjoyment. However, to obtain a certificate, you must follow the rules set by the FAA. You'll also need to pass an exam and complete a few forms. To take a test, you must have a government-issued picture ID. The FAA requires a background check before issuing you a certificate. If you fail, you h

Drone Mapping 101

  If you're interested in drone mapping, there are many things you should know. We'll cover the basics of the technology, including the differences between LiDAR and photogrammetry, the importance of maintaining visibility, and how to conduct GIS analysis. Plus, you'll find some tips for using your drone to map coastal terrain. Photogrammetry vs. LiDAR When choosing the best technology for your project, it's essential to understand the differences between photogrammetry and LiDAR. Each technology has its own benefits and drawbacks, so it's critical to consider your project's needs and budget when deciding. Photogrammetry is a passive technology that uses cameras and photographs to create 3D models. It's ideal for projects that require visual assessment and mapping. It also offers excellent accuracy. Photogrammetry can produce accurate results, even at night. Depending on the size of your project, the process may take a few hours or a few days. You'll nee

The Evolution of the Unmanned Surface Vehicle (USV)

  If you're interested in the Unmanned Surface Vehicles (USVs) market, you will be glad to know that the demand is rising, especially with the COVID-19 pandemic. However, you also have to bear in mind some challenges. Challenges faced by USVs Unmanned surface vehicles (UUVs) are a type of unmanned aerial vehicle (UAV). These robots are specially designed to address environmental issues. They can be deployed for various purposes, such as search & rescue and damage assessment. UUVs also can operate in a wide range of environments. There are some different challenges that UUVs face, including water force and navigation, obstacle avoidance, and safety. For example, water force can knock an acoustic camera out of alignment, and it is often difficult to accurately localize a UAV in the water. Situational awareness is a primary function of USV sensors in disaster sites. This may include underwater mapping sensors, microphones, speakers, and 360 cameras. A bird's eye view can help

Uncrewed Aerial Vehicles and Collisions

Uncrewed aerial vehicles are often used for various applications, including military training and reconnaissance. These vehicles are equipped with a range of sensors and a separation-management system designed to avoid collisions. They are also known for their ability to travel at extremely high speeds. Despite their speed, they are very stable and can handle several landings and take-offs, making them popular among commercial and recreational pilots. Separation management The emergence of unmanned aerial vehicles in the airspace has led to the need for safe separation management for these aircraft. This paper provides a brief overview of recent research in this area. In addition, the article reviews the most essential technologies for collision avoidance in integrated airspace. The UAS operating environment is a complex and variable one. To achieve safe and efficient operation, standardization of processes is necessary. The international community has conducted an impressive amount of

UAV Obstacle Avoidance 101

  When you are a UAV operator, the chances are that you have come across the phrase "UAV obstacle avoidance." This article will give you an overview of what this term means and how to implement it in your system. You will learn to avoid objects, detect pedestrians, and use sensors to track and follow objects. It is an excellent resource for anyone interested in UAVs. Object descriptors Object descriptors for UAV obstacle avoidance are a significant problem that affects many autonomous systems. This task aims at the highest accuracy while remaining within the computational budget. There are many approaches to building 3D models of obstacles in the environment. One of these uses a polynomial regression to fit sensor measurements. Another system uses a stereo camera to calculate the distance between obstacles. This approach is a novelty. In addition to estimating the object's size, the algorithm calculates its position and motion. The algorithms used in this research were ev

How Does LIDAR Work?

  LIDAR (Light Detection and Ranging) technology is a relatively new method of capturing images in the air, sea, and earth. By using millimeter-wave radar, cameras, and sensors, it can be used to map the surface of any area, identify traffic signs and road markings, and detect obstacles. It can also calculate phytoplankton fluorescence and biomass on the ocean surface. Identifying traffic signs and road markings LiDAR has the potential to provide a comprehensive, accurate, and detailed view of the road. This can be used for some applications, including traffic signs and road marking recognition. For example, a LiDAR image produces a three-dimensional point cloud representing a computer's understanding of the physical world. The point cloud can be annotated with tagging and semantic segmentation. This information can be used to build a pavement marking management program. The system's findings will guide the MassDOT's repair frequency and selection of marking materials. The
