论文摘要
本文提出了一种轻巧,有效的校准神经网络模型,用于降低低成本的微电力系统(MEMS)陀螺仪,并实时估算机器人的态度。关键思想是从惯性测量单元(IMU)测量的时间窗口中提取本地和全局特征,以动态地回归陀螺仪的输出补偿组件。遵循精心推导的数学校准模型,LGC-NET利用可分开的卷积捕获截面特征并减少网络模型参数。较大的内核注意力旨在更好地学习远程依赖性和特征表示。在EUROC和TUM-VI数据集中评估了所提出的算法,并在具有更轻巧模型结构的(看不见的)测试序列上实现了最先进的测试序列。我们的LGC-NET的估计取向与排名最高的视觉惯性探光系统相当,尽管它不采用视觉传感器。我们在:https://github.com/huazai665/lgc-net上进行开源方法
This paper presents a lightweight, efficient calibration neural network model for denoising low-cost microelectromechanical system (MEMS) gyroscope and estimating the attitude of a robot in real-time. The key idea is extracting local and global features from the time window of inertial measurement units (IMU) measurements to regress the output compensation components for the gyroscope dynamically. Following a carefully deduced mathematical calibration model, LGC-Net leverages the depthwise separable convolution to capture the sectional features and reduce the network model parameters. The Large kernel attention is designed to learn the long-range dependencies and feature representation better. The proposed algorithm is evaluated in the EuRoC and TUM-VI datasets and achieves state-of-the-art on the (unseen) test sequences with a more lightweight model structure. The estimated orientation with our LGC-Net is comparable with the top-ranked visual-inertial odometry systems, although it does not adopt vision sensors.
