Q1. What is Scan Matching in ICP algorithm?
Ans. 
Scan matching in ICP algorithm involves aligning two sets of scan data to find the transformation that minimizes the difference between them.
• Scan matching is a key step in Iterative Closest Point (ICP) algorithm used for registering point clouds.

• It involves finding the transformation (translation and rotation) that aligns two sets of scan data.

• The goal is to minimize the difference between the two sets of points by ite...read more

Q2. Explain the navigation stack.
Ans. 
The navigation stack is a collection of software components that work together to enable a robot to navigate autonomously in its environment.
• The navigation stack typically includes components such as localization, mapping, path planning, and obstacle avoidance.

• Localization is the process of determining the robot's position and orientation in the environment.

• Mapping involves creating a map of the environment using senso...read more

Q3. Explain VSLAM stack
Ans. 
VSLAM stack stands for Visual Simultaneous Localization and Mapping stack, used in robotics for navigation and mapping.
• VSLAM stack combines visual data from cameras with sensor data for localization and mapping in real-time

• It typically includes components like feature extraction, feature matching, camera calibration, and pose estimation

• Popular VSLAM algorithms include ORB-SLAM, LSD-SLAM, and PTAM

Q4. What is loop closer in VSLAM and Scan matching
Ans. 
Loop closer in VSLAM and Scan matching is a technique used to optimize the trajectory of a robot by closing loops in the map.
• Loop closer is responsible for correcting accumulated errors in the estimated trajectory of a robot in VSLAM.

• It helps in aligning the current scan data with the previously mapped environment to improve localization accuracy.

• Loop closer can be implemented using techniques like loop closure detecti...read more
