Camera Relocalization

Cambridge Landmarks, a large scale outdoor visual relocalisation dataset taken around Cambridge University. Contains original video, with extracted image frames labelled with their 6-DOF camera pose and a visual reconstruction of the scene.

Univesity is an indoor localization dataset proposed in "Camera Relocalization by Computing Pairwise Relative Poses Using Convolutional Neural Network". It contains camera images and ground-truth poses, split in 9694 training pairs and 5068 test pairs. It was created to test localization of multiple scenes in one global coordinate frame, and has a bigger indoor environment compared to 7scenes.

DeepLoc is a large-scale urban outdoor localization dataset. The dataset is currently comprised of one scene spanning an area of 110 x 130 m, that a robot traverses multiple times with different driving patterns. The dataset creators use a LiDAR-based SLAM system with sub-centimeter and sub-degree accuracy to compute the pose labels that provided as groundtruth. Poses in the dataset are approximately spaced by 0.5 m which is twice as dense as other relocalization datasets. Furthermore, for each image the dataset creators provide pixel-wise semantic segmentation annotations for ten categories: Background, Sky, Road, Sidewalk, Grass, Vegetation, Building, Poles & Fences, Dynamic and Void. The dataset is divided into a train and test splits such that the train set comprises seven loops with alternating driving styles amounting to 2737 images, while the test set comprises three loops with a total of 1173 images. The dataset also contains global GPS/INS data and LiDAR measurements. This dataset can be very challenging for vision based applications such as global localization, camera relocalization, semantic segmentation, visual odometry and loop closure detection, as it contains substantial lighting, weather changes, repeating structures, reflective and transparent glass buildings.

This dataset comprehends the 3D building information model (in IFC and Revit formats), manually elaborated based on the terrestrial laser scanner of the sequence 2 of ConSLAM, and the refined ground truth (GT) poses (in TUM format) of sessions 2, 3, 4, and 5 of the open-access ConSLAM dataset (which provides camera, LiDAR, and IMU measurements). This dataset enables the evaluation of pose estimation algorithms, such as localization, odometry, SLAM, and Bundle adjustment. Given the differences between the real-world and the 3D reference BIM model (Scan-Map deviations), the dataset is appropriate for evaluating long-term localization and mapping capabilities, i.e., methods that are robust to changes in the environment. In particular, in a real-world construction environment with normal clutter (not as in the Hilti dataset).

ConSLAM is a real-world dataset collected periodically on a construction site to measure the accuracy of mobile scanners' SLAM algorithms. The dataset contains time-synchronized and spatially registered RGB and NIR images and 360-deg LiDAR scans, 9-axis IMU measurements, and professional ground-truth terrestrial laser scans. This dataset reflects the periodic need to scan construction sites with the aim of accurately monitoring progress using a hand-held scanner. The sensors used for data acquisition are: - LiDAR: Velodyne VLP-16. - RGB camera: Alvium U-319c, 3.2 MP. - NIR camera: Alvium 1800 U-501, 5.0 MP. - 9-axis IMU: Xsens MTi-610.

They make available a dataset of 655 places, collected by non-expert users world-wide.

This dataset builds upon the SpaGBOL dataset - a graph-based dataset covering numerous cities across the globe for the purpose of structured city-scale Cross-View Geo-Localisation (CVGL). We introduce the idea of Multi-View Geo-Localisation (MVGL) - localising in two steps within a graph. First using CVGL to retrieve the most likely primary nodes (road junctions), before performing relative pose estimation also candidate edges to increase precision. The corresponding initial network proposed reduced median error from hundreds of metres down to approximately 22m error across the entire dataset.
