• 11:54, 30 May 2023 Mr. MacKenty talk contribs created page Odometry sensor (Created page with "An odometry sensor is a device used to estimate the change in position over time of a vehicle, like a car or a robot, based on data from its own sensors. The term "odometry" comes from the combination of "hodos", meaning path or way in Greek, and "metron", meaning measure. Therefore, it's all about measuring the path a vehicle takes. There are several types of odometry sensors, and they work in different ways: # '''Wheel Encoders''': In many robots, especially wheeled...")
• 11:53, 30 May 2023 Mr. MacKenty talk contribs created page Object occlusion (Created page with "Object occlusion in the context of computer vision refers to the event where a part or all of an object in the scene is hidden from view by some other object in the scene. In simple words, when an object is in front of another object, blocking it from view, we say that the second object is occluded. For example, imagine you are looking at a photograph of a crowd of people. Some of those people may be standing in front of others, preventing you from seeing the people beh...")
• 11:51, 30 May 2023 Mr. MacKenty talk contribs created page Light detection and ranging (LIDAR) (Created page with "Light Detection and Ranging, more commonly known as LiDAR, is a method of remote sensing that uses light in the form of a pulsed laser to measure distances to an object. These light pulses, combined with other data recorded by the airborne system, generate precise, three-dimensional information about the shape of the Earth and its surface characteristics. Here's a simplified explanation of how it works: # A LiDAR system sends out a pulse of light, usually in the form o...")
• 11:50, 30 May 2023 Mr. MacKenty talk contribs created page Key points/pairs (Created page with "Key points, also known as feature points or interest points, are distinct and unique points in an image that are easy to find and accurately describe. These points are usually selected because they represent corners, edges, or other interesting aspects of the image, and they are used in many computer vision tasks for things like object recognition, image alignment, and 3D reconstruction. When multiple images are used (for example, in a video or a sequence of frames take...")
• 11:48, 30 May 2023 Mr. MacKenty talk contribs created page Keyframe selection (Created page with "Keyframe selection is a term commonly used in the field of computer vision, especially in video processing and robotics. A keyframe is a frame in a sequence of frames (like a video or a series of images) that contains important or critical data. In video compression, for example, keyframes (also known as I-frames) are the frames from which subsequent frames are based. These keyframes serve as reference points and the frames in between are often compressed by storing onl...")
• 11:46, 30 May 2023 Mr. MacKenty talk contribs created page Inertial measurement unit (IMU) (Created page with "An Inertial Measurement Unit, or IMU, is a device that measures and reports on a vehicle's velocity, orientation, and gravitational forces, using a combination of accelerometers, gyroscopes, and sometimes magnetometers. IMUs are typically used to aid in navigation and tracking systems, particularly when GPS data is unavailable or unreliable. Let's break down the components of an IMU: # '''Accelerometers:''' These measure linear acceleration. However, they can't disting...")
• 11:45, 30 May 2023 Mr. MacKenty talk contribs created page Human pose estimation (HPE) (Created page with "Human pose estimation (HPE) is a computer vision task that involves determining the position and orientation of the human body, along with the positions of various body parts such as the head, arms, legs, and so on, usually in real-time. Here's a simplified way to think about it: Imagine you're looking at a photo of a person. You can probably tell what position they're in — maybe they're standing up straight, sitting down, or running. Now imagine trying to teach a com...")
• 11:44, 30 May 2023 Mr. MacKenty talk contribs created page GPS-denied environment (Created page with "A GPS-denied environment is a location or situation where the Global Positioning System (GPS) signals are not available at all. This can occur for a number of reasons: # Indoor Locations: Buildings often block GPS signals, making them unavailable inside. # Underground or Underwater: Similarly, GPS signals can't penetrate underground or underwater. # Jamming or Spoofing: GPS signals can be intentionally disrupted or blocked using devices known as GPS jammers. Additionall...")
• 11:41, 30 May 2023 Mr. MacKenty talk contribs created page GPS-degraded environment (Created page with "A GPS-degraded environment refers to any situation or location where the Global Positioning System (GPS) signals are unreliable, weak, or completely unavailable. This could be due to several reasons: 1. **Urban Areas**: In cities with high buildings, GPS signals can become degraded due to the "urban canyon" effect. The tall buildings can block direct signals from the satellites or cause multipath errors, where the signals bounce off multiple buildings before reaching th...")
• 11:39, 30 May 2023 Mr. MacKenty talk contribs created page Global positioning system (GPS) signal (Created page with "The Global Positioning System (GPS) is a satellite-based navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. Here's a simplified explanation of how it works: # The GPS system consists of a network of around 30 satellites orbiting the Earth, controlled by a series of ground stations. These satellites are always transmitting sign...")
• 11:38, 30 May 2023 Mr. MacKenty talk contribs created page Global map optimization (Created page with "Global map optimization is an important concept in robotics, particularly in the field of simultaneous localization and mapping (SLAM). In essence, it's the process of improving the accuracy and consistency of a map that a robot has created of its environment. Here's how it works: as a robot moves through its environment, it's continually taking sensor measurements and using those to build up a map of the world around it. At the same time, it's using that map to estimat...")
• 11:36, 30 May 2023 Mr. MacKenty talk contribs created page Edge computing (Created page with "Edge computing is a distributed computing paradigm that brings computation and data storage closer to the sources of data. This is done to improve response times and save bandwidth. The "edge" refers to the edge of a network, closer to the devices that produce or consume data, as opposed to a centralized data center or cloud. Here are the key steps involved in setting up an edge computing environment: # Identify the Need: The first step is to understand why you need ed...")
• 11:34, 30 May 2023 Mr. MacKenty talk contribs created page Dead reckoning data (Created page with "Dead reckoning is a process used in navigation to determine one's current position based on a previously known position, or fix, and advancing that position based upon known or estimated speeds over a period of time, and the direction in which the person or vehicle is known or estimated to have moved. The name "dead reckoning" comes from "deduced reckoning," sometimes abbreviated as 'ded' reckoning, which has been further abbreviated to "dead" reckoning. In the context...")
