Jhacson Meza

I am an ELLIS PhD student at the Czech Technical University in Prague supervised by Torsten Sattler and Martin Oswald. My research interests lie in 3D vision and 3D reconstruction.

I recevied my MSc degree in Electrical and Electronics Engineering, where I developed a 3D multimodal imaging system by combining the 3D freehand ultrasound and structured light techinques. I received my BSc degree in Mechatronics Engineering working on terrain 3D reconstruction for civil engineering applications using the Structure-from-Motion pipeline.
