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..." current

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..." current

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..." current

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..." current

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..." current

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..." current

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..."

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..." current
12:3812:38, 30 May 2023 diff hist +1,684‎ N 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..." current

12:3612:36, 30 May 2023 diff hist +2,070‎ N 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..."

The name "dead reckoning" comes from "deduced reckoning," sometimes abbreviated as 'ded' reckoning, which has been further abbreviated to "dead" reckoning. In the context..." current

Essentially, it's about teaching computers to "see" and understand digital images or videos. The way computer vision does this is by taking images or videos, processing them, and then extracting useful information from them. This can involve many different tasks, such as: # Image Recognition: This is one of the m..."

You can think of rescue robots as needing to understand the world around them, just like you and me. When these robots look at a scene through their sensors, which typically include cameras, they need to determine the 3D positions of objects in the scene, as well as the position and orientation of the..." current
