FORAY - Completion of Non-ML Detection of the Ball

Aaron John Sabu

The ball detection algorithm (without the use of a trained model) has been completed. Following the work posted in the last blogpost, I realized that it may be a better idea to isolate the ball away from its environment and determine its bounding box in the cropped image. The first analysis of the b...

FORAY - Near-perfect calculation of ball location and scope for better estimation

Aaron John Sabu

Over the last two weeks, I have been working on the existing code by Parth Agrawal for the estimation of the location of the green ball from images that were shot at different angles. The code had estimated the position of the ball quite well for the hi-def images but not so for the 800x600 images:...

FORAY - Testing the streaming function of opti-track system

Zhaoliang Zheng

Current progress: In the past week, I tested the opti-track system streaming function. Before, after I used opti-track to capture the motion of our flying blimps, I had to manually import the data to a csv file and then process the csv file. This whole process took a very long time since in the...

FORAY - Testing control using camera

Zhaoliang Zheng

In order to verify the use of camera automation control, I set up a camera on a quadrotor. I will use this as testbed to understand and test some algorithm and data on it. Right now, I can use this camera to proceed Wifi remote control:
