CYCLOPS: A cyclists' orientation data acquisition system using RGB camera and inertial measurement units (IMU)
The files in this data repository are a supplement to the paper "CYCLOPS: A cyclists' orientation data acquisition system using RGB camera and inertial measurement units (IMU)", which introduces an acquisition system developed to capture images and inertial measurement data of moving cyclists from a vehicle. The system described s 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 to acquire 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 for devices installation, IMUs configuration, and software installation on the laptop. By developing this system, the need to acquire data for training machine learning models capable of predicting the motion intentions of vulnerable road users (VRU), particularly cyclists, is addressed.
