Sample, Crop, Track: Self-Supervised Mobile 3D Object Detection for Urban Driving LiDAR

ICRA 2023poster

Deep learning has led to great progress in the detection of mobile (i.e. movement-capable) objects in urban driving scenes in recent years. Supervised approaches typically require the annotation of large training sets; there has thus been great interest in leveraging weakly, semi- or self- supervise…

Real-Time Hybrid Mapping of Populated Indoor Scenes using a Low-Cost Monocular UAV

IROS 2022poster

Unmanned aerial vehicles (UAVs) have been used for many applications in recent years, from urban search and rescue, to agricultural surveying, to autonomous underground mine exploration. However, deploying UAVs in tight, indoor spaces, especially close to humans, remains a challenge. One solution, w…

When the Sun Goes Down: Repairing Photometric Losses for All-Day Depth Estimation

CoRL 2022poster

Self-supervised deep learning methods for joint depth and ego-motion estimation can yield accurate trajectories without needing ground-truth training data. However, as they typically use photometric losses, their performance can degrade significantly when the assumptions these losses make (e.g. temp…

Beyond Controlled Environments: 3D Camera Re-Localization in Changing Indoor Scenes

ECCV 2020poster

Long-term camera re-localization is an important task with numerous computer vision and robotics applications. Whilst various outdoor benchmarks exist that target lighting, weather and seasonal changes, far less attention has been paid to appearance changes that occur indoors. This has led to a mism…

Calibrating Deep Neural Networks using Focal Loss

NeurIPS 2020poster

Miscalibration -- a mismatch between a model's confidence and its correctness -- of Deep Neural Networks (DNNs) makes their predictions hard to rely on. Ideally, we want networks to be accurate, calibrated and confident. We show that, as opposed to the standard cross-entropy loss, focal loss (Lin et…

On-The-Fly Adaptation of Regression Forests for Online Camera Relocalisation

CVPR 2017oral

Camera relocalisation is an important problem in computer vision, with applications in simultaneous localisation and mapping, virtual/augmented reality and navigation. Common techniques either match the current image against keyframes with known poses coming from a tracker, or establish 2D-to-3D cor…

Straight to Shapes: Real-Time Detection of Encoded Shapes

CVPR 2017poster

Current object detection approaches predict bounding boxes that provide little instance-specific information beyond location, scale and aspect ratio. In this work, we propose to regress directly to objects' shapes in addition to their bounding boxes and categories. It is crucial to find an approp…

Staple: Complementary Learners for Real-Time Tracking

CVPR 2016poster

Correlation Filter-based trackers have recently achieved excellent performance, showing great robustness to challenging situations exhibiting motion blur and illumination changes. However, since the model that they learn depends strongly on the spatial layout of the tracked object, they are notoriou…

Incremental dense semantic stereo fusion for large-scale semantic scene reconstruction

ICRA 2015poster

Our abilities in scene understanding, which allow us to perceive the 3D structure of our surroundings and intuitively recognise the objects we see, are things that we largely take for granted, but for robots, the task of understanding large scenes quickly remains extremely challenging. Recently, sce…
