| Basic Recording | Recording a limited number of sensors on a single NVIDIA® Xavier® processor. |
| Distributed Recording | Synchroneously recording data on sensors distributed across multiple NVIDIA DRIVE™ platforms. |
| High Throughput Recording | Developing strategies for recording the huge amounts of data that multiple cameras can produce. |
NVIDIA® DriveWorks SDK contains recording tools that can record, synchronize, and playback the data captured from multiple devices attached to your NVIDIA DRIVE™ platforms. You can use the recording tools to test sample applications that interact with sensors:
- GUI or command line (CLI) recorder tools save sensor data to USB device or another data storage device connected through Ethernet.
- Replayer tool feeds previously recorded sensor data into your sample application.
The recording applications data can then store the data on a eSATA/USB Drive. The data from each sensor is synchronized with data from other sensors by adding a time stamp to the data.
Recording Capabilities
The following shows DriveWorks recording capabilities:
Each sensor acquires and transfers the data to one of the NVIDIA® Xavier® processors on the device. Depending on sensor type, the data may first go through a post-processing step (ex. encoding for camera) prior to disk serialization. It is important to ensure the storage device's bandwidth and capacity are sufficient for the sensor set.
