Questions tagged [slam]

This tag is for code related to SLAM (Simultaneous Localization and Mapping (SLAM) which is the computational problem, often related to robotics and/or drones, of constructing or updating a map of an unknown environment while simultaneously keeping track of an agent's location within it.

The following definition from Wikipedia:

In robotic mapping, simultaneous localization and mapping (SLAM) is the computational problem of constructing or updating a map of an unknown environment while simultaneously keeping track of an agent's location within it. While this initially appears to be a chicken-and-egg problem there are several algorithms known for solving it, at least approximately, in tractable time for certain environments. Popular approximate solution methods include the particle filter and extended Kalman filter.

SLAM algorithm implementation in C++ that's compatible with windows?

I need a SLAM algorithm for a robot that will move around a track while avoiding obstacles (only one lap so loop will be closed at the end). The robot uses GPS, compass and lidar for navigation. I was about to implement a version of online graph…

How to generate irregular time intervals?

I intend to make a simulation of real-data ie produce data at irregular time intervals. Below is some prototype code I wrote in python to simulate irregular time(not data), but the results are that my loop runs too fast such that each "time"(dat)…

HOWTO: Robot Operating System large area navigation

Consider I have a very large map (e.g. a map of New York City) which definitely cannot be load in the memory. Are there any solutions for ros to handle such situation? In another word, are there any solutions(or research) in robot area for large…

Kudan in Unity: how to stop or reset markerless tracking?

I am creating an application with Kudan where a photograph (a 2D sprite) appears via markerless tracking. Based on the sample project I've successfully made adjustments so that the 2D plane is always perpendicular to the camera and placed on the…

Using xSense in mrpt

I am a new user of mrpt library ! My project is about using IMU data (xSense 4th generation). However, I guess that some xSense data are already treated through an AHRS filter (sort of embedded Kalman filter from the documentation). And I am not…
