Abstract

This paper introduces CYCLOPS, an acquisition system developed to capture images and inertial measurement data of moving cyclists from a vehicle. The development of CYCLOPS addresses the need to acquire useful data for training machine learning models capable of predicting the motion intentions of cyclists on urban roads. Considering its application, it is a completely original development. The system consists of two devices. The first device is installed on the bicycle and is based on an electronic acquisition board comprising an inertial measurement unit (IMU), a microcontroller, and a transceiver for sending the cyclist's acceleration and orientation data to a vehicle. The second device is installed on the vehicle and uses the same board architecture to acquire the vehicle's accelerations and orientations, along with an RGB monocular camera. The data is stored in real-time in a laptop's drive for subsequent analysis and manipulation. The hardware architecture is presented in detail, including the designs to install the devices, for IMUs configuration, and software installation on the laptop. All design and software files required to develop the proposed system are available for download at: doi.org/10.17632/3yx5y8b7tm.1, licensed under the Open-source license CC BY 4.0.

摘要

本文介绍了CYCLOPS，这是一种用于从车辆上捕获移动自行车骑行者图像和惯性测量数据的采集系统。CYCLOPS的开发满足了获取有用数据以训练能够预测城市道路上骑行者运动意图的机器学习模型的需求。考虑到其应用，这是一项完全原创的开发。该系统由两个设备组成。第一个设备安装在自行车上，基于一个电子采集板，该采集板包括一个惯性测量单元（IMU）、一个微控制器以及一个用于将骑行者的加速度和方向数据发送到车辆的收发器。第二个设备安装在车辆上，使用相同的板卡架构来获取车辆的加速度和方向，同时配备一个RGB单目摄像头。数据实时存储在笔记本电脑的驱动器中，以便后续分析和处理。文中详细介绍了硬件架构，包括设备安装设计、IMU配置以及笔记本电脑上的软件安装。开发该系统所需的所有设计和软件文件可在doi.org/10.17632/3yx5y8b7tm.1下载，遵循开源许可协议CC BY 4.0。
