| Summary: | MiroSot is an area where robotics fields such as mobility structure, artificial intelligence. vision system, multi-agents, wireless communication and autonomous behaviour are of
paramount importance. One of the most crucial parts of this overall system is the vision
system. This system could determine the winning factor during a MiroSot competition. In
this project, we are implementing a local vision system to determine the motion and
behaviour of the soccer robot instead of a global vision system that is currently being used.
Since there is limitation in the size of the mobile robot as stated in the MiroSot rules, hence
some modification needs to be done on the vision system. A monocular vision system is
used as an alternative to the more popular stereo vision system without neglecting the
depth estimation aspect to determine ball distance and position. By using the CamShift
algorithm to detect the ball, we use the ball diameter to estimate the distance of the ball.
The calibration data has been tested and has shows that it gives accurate and precise
distance estimation. By using this information, the soccer robot will try to avoid any
obstacle by performing a sequence of movements. The details on how we obtained the
calibration data for depth estimation and the testing phase have also been provided in this
thesis. We also show how we test our control system and the results can be found in result
chapter. The long term goal behind this project is to create a biologically inspired vision
system for the soccer robot. |
