File I/O

Read and visualize automotive data from external sources

Automated Driving Toolbox™ provides several features to read and visualize automotive data from various third-party files. There is a wide variety of file formats available in the industry, which store automotive data in different formats. Automotive data includes data from sensors such as lidars, IMUs, cameras as well as vehicle state information, CAN messages and any other custom measurements.

Velodyne® lidars store point cloud data in packet capture (PCAP) files. Point clouds are also stored in PLY or PCD files. Ibeo® sensors, which are developed by Ibeo Automotive Systems, create Ibeo data container files that can contain data for multiple sensors simultaneously, such as IMU, GPS, camera, and lidar. ADTF (Automotive Data and Time-Triggered Framework) is a data format developed by Elelktrobit that can also store data from multiple automotive sensors simultaneously. HERE HD Live Map (HERE HDLM) is a web service that provides high-definition map data for automated driving applications.

Automated Driving Toolbox supports reading and visualizing data from all the file formats above. Other file formats may require additional toolbox licenses.
