SBlob Readings from Eyebot Perspective Camera

Postby sn17 » Fri Jul 20, 2018 11:52 am

I'm currently utilizing the eye-bot perspective camera to detect light sources in the environment which works as advertised. However, as I understand it the coordinates given in the SBlob object (X,Y) are relative to the eye-bot and not the global frame? On further inspection however the obtained values are too large to be of that format (upwards of 200 when the arena is only (10,10,5)?). The SBlob documentation indicates that is contains polar coordinates with distances from the robot center in cm and pixels provided, however it seems this would only apply to the foot-bot?

Clarification on the above would be much appreciated!

Somewhat resolved, this forum topic details the SI units used in the arena (meters) vs those used returned by sensors (centimeters).
