Dataset for "Parameter Reduction and Optimisation for Point Cloud and Occupancy Mapping Algorithms"

In the applications of occupancy mapping, the scene to be explored is normally large and objects are of irregular shapes. In this case, it is difficult to evaluate the performance of a mapping approach since the ground truth can hardly be obtained. This dataset aims to provide small measured scenes with ground truths for evaluation purposes.

Videos are recorded in .svo files. These files can be opened with the tools provided in ZED SDK which can be downloaded at Stereo Labs website (https://www.stereolabs.com). Images in the videos can be extracted using the API in ZED SDK and the camera parameters can also be accessed by ZED API.

Ground truth files are in .ot format. These files can be viewed by octovis package. To install octovis, run 'sudo apt-get install octovis' in Ubuntu.

Camera trajectories produced by ORB-SLAM and keyframe poses produced by ORB-SLAM are in .txt files. Most text editors can open files of this type.

Documentation

Data collection method:

This dataset contains 20 video files used for occupancy mapping. The dataset was recorded with a ZED stereo camera (Stereo Labs, USA) in two environments at University of Bath, in front of buildings and in a parking lot. Targets in the dataset are two boxes whose external surfaces are either with a plain brown cardboard texture or are covered with randomly generated Voronoi diagrams. The average size of the polygons in each diagram is about 3 cm x 3 cm. The colour of each polygon is randomly generated. The Voronoi diagrams are printed in 300 DPI on the posters of A0 size and cropped to cover the surfaces of boxes. Two boxes are arranged in a layout as one of five free tetrominoes, i.e., I, O, T, L and S, in the Tetris game. The camera obits the boxes twice in a anti-clock direction to capture videos. Ground truths are also included in this dataset package.

Technical details and requirements:

The device for data collection is a ZED camera from Stereo Labs, USA. Software is ZED SDK which is available at https://www.stereolabs.com.
