In this post, I’ll describe the lessons learnt from trying to sample IMU sensors to obtain raw gyroscope and accelerometer data as input to sensor […]

In the last post, we applied bundle adjustment to optimize camera intrinsic and extrinsic parameters keeping the position of the object points fixed. In this […]

In the previous posts we considered how to calculate the Jacobians for Bundle Adjustment (BA) and their relative magnitudes and some of their properties. In […]

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 (BA) is a well established technique in Computer Vision typically used as the last step in many feature based 3D reconstruction algorithms to […]

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 […]

In part 1 of this series, we examined the issue of depth of field and its relationship with aperture and focal length in detail. We […]

Most applications of commercial drones today involve aerial photographs as an input. Taking good photos from a moving platform involves a number of challenges, some […]

I have been working on making an extension to PHP to read data (Mavlink messages) from a serial port on a Windows machine. PHP on […]
