Francesco Nazzaro - Image recognition and camera positioning with OpenCV. A tourist guide application. [EuroPython 2015] [21 July 2015] [Bilbao, Euskadi, Spain] OpenCV Python bindings provide several ready to use tools for camera calibration, image recognition and camera position estimation. This talk will show how to recognize a picture, from a library of known paintings, and compute the camera position with respect to the recognized picture using OpenCV and numpy. This is applied to a tourist guide application for Google Glass through the recognition of the paintings exposed in the museum.
