Video quality depends on sender mobile, network and the receiver device.The streaming protocol handles network…See More

A Python Experiment in Gyro Calibration & Drift Cancelling

Posted on June 13, 2015 at 7:12pm 0 Comments

This article is to share my findings in gyro calibration. I tried to make a python script that uses data comes from mobile phone [S5 that has 6050 IMU]. It was a good chance to write simple code and visualize results much easier than doing so on Arduino with IMU 6050 attached. But still the concept…
