摘要:

基于视觉数据的全局定位是一个适用于许多机器人领域的挑战性问题。先前的研究表明,可以训练神经网络将环境图像映射为该环境内的绝对相机位姿,从而在此过程中学习隐式神经映射。在本研究中,我们评估了该方法在真实世界机器人场景中的适用性,并证明通过将问题约束在2维空间并大幅增加训练数据量,可以使用一个能够在嵌入式平台上进行实时推理的紧凑模型来实现数厘米的定位精度。我们将训练好的模型部署在UGV平台上,展示了其在航点导航任务中的有效性。在该任务中,该模型在UGV车载CPU上以6fps的速率运行,在嵌入式GPU上以35fps的速率运行,或在桌面GPU上以220fps的速率运行,能够实现9cm的平均定位精度。伴随本研究,我们将发布一个新颖的定位数据集,包含模拟和真实环境,每个环境都有数万个训练样本。

英文摘要:

Global localisation from visual data is a challenging problem applicable to many robotics domains. Prior works have shown that neural networks can be trained to map images of an environment to absolute camera pose within that environment, learning an implicit neural mapping in the process. In this work we evaluate the applicability of such an approach to real-world robotics scenarios, demonstrating that by constraining the problem to 2-dimensions and significantly increasing the quantity of training data, a compact model capable of real-time inference on embedded platforms can be used to achieve localisation accuracy of several centimetres. We deploy our trained model onboard a UGV platform, demonstrating its effectiveness in a waypoint navigation task, wherein it is able to localise with a mean accuracy of 9cm at a rate of 6fps running on the UGV onboard CPU, 35fps on an embedded GPU, or 220fps on a desktop GPU. Along with this work we will release a novel localisation dataset comprising simulated and real environments, each with training samples numbering in the tens of thousands.
