Sensor Fusion: Part 4
In this post, we’ll add the math and provide implementation for adding image based measurements. Let’s recap the notation and geometry first introduced in part […]
Sensor Fusion – Part 3: Implementation of Gyro-Accel Sensor Fusion
In the previous posts, we laid the mathematical foundation necessary for implementing the error state kalman filter. In this post, we’ll provide the Matlab implementation […]
Sensor Fusion: Part 2 (combining Gyro-Accel data)
In the previous post, we laid some of the mathematical foundation behind the kalman filter. In this post, we’ll look at our first concrete example […]
Sensor Fusion: Part 1
In this series of posts, I’ll provide the mathematical derivations, implementation details and my own insights for the sensor fusion algorithm described in 1. This paper describes a […]
Bundle Adjustment – Part 2: Jacobians
In the previous post, we considered the basics of bundle adjustment (BA) and discussed how to obtain the expressions for the jacobian matrices for the […]
Bundle Adjustment – Part 1: Jacobians
Bundle Adjustment (BA) is a well established technique in Computer Vision typically used as the last step in many feature based 3D reconstruction algorithms to […]
Note on POSIT
The purpose of the this post is to provide my thoughts on what goes on during an iteration of POSIT. This post is not meant to […]
