We present the Toulouse Vanishing Points Dataset, a public photographs database of Manhattan scenes taken with an iPad Air 1. The purpose of this dataset is the evaluation of vanishing points estimation algorithms. Its originality is the addition of Inertial Measurement Unit (IMU) data synchronized with the camera under the form of rotation matrices. Moreover, contrary to existing works which provide vanishing points of reference in the form of single points, we computed uncertainty regions.

Some photos of the dataset with their ground truth line segments:

The dataset containing the photographs and the ground truths can be downloaded here: http://ubee.enseeiht.fr/tvpd/tvpd.zip

We developed an iOS application to record the orientation of the camera at the moment a photo is taken. This application is compatible with iPhone and iPad running on iOS 7. The orientation is provided in the form of change of basis matrices from the world reference frame to the camera frame and is stored in the EXIF UserComment field. This application is not present on the Apple App Store, however we provide its source code released under the BSD license. Download the source code of the iOS application.
