Experience
Autonomous Parking Agent V3
I designed and developed a self-parking car that can also be controlled by Bluetooth with an Android App. Range sensing was implemented using sonar sensors and IR range sensors. The car was built at a scale of 1:10 and uses an NXP Qorivva MPC5706B MCU.
Depth Perception using Stereo Cameras
I designed and developed a stereo depth-perception system that is based on Heiko Hirschmüller's semi-global matching (SGM) algorithm. The system uses two Raspberry PI Model B computing nodes and the images are captured with synchronized 5MP video cameras.
