Uncertainty Estimation in One-Stage Object Detection
Environment perception is the task for intelligent vehicles on which all
subsequent steps rely. A key part of perception is to safely detect other road
users such as vehicles, pedestrians, and cyclists. With modern deep learning
techniques huge progress was made over the last years in this field. However
such deep learning based object detection models cannot predict how certain
they are in their predictions, potentially hampering the performance of later
steps such as tracking or sensor fusion. We present a viable approaches to
estimate uncertainty in an one-stage object detector, while improving the
detection performance of the baseline approach. The proposed model is evaluated
on a large scale automotive pedestrian dataset. Experimental results show that
the uncertainty outputted by our system is coupled with detection accuracy and
the occlusion level of pedestrians
Recognize Moving Objects Around an Autonomous Vehicle Considering a Deep-learning Detector Model and Dynamic Bayesian Occupancy
International audiencePerception systems on autonomous vehicles have the challenge of understanding the traffic scene in different situations. The fusion of redundant information obtained from different sources has been shown considerable progress under different methodologies to achieve this objective. However, new opportunities are available to obtain better fusion results with the advance of deep-learning models and computing hardware. In this paper, we aim to recognize moving objects in traffic scenes through the fusion of semantic information with occupancy-grid estimations. Our approach considers a deep-learning model with inference times between 22 to 55 milliseconds. Moreover, we use a Bayesian occupancy framework with a Highly-parallelized design to obtain the occupancygrid estimations.We validate our approach using experimental results with real-world data on urban scenery
