Basic Recording

Recording a limited number of sensors on a single SoC.

High Throughput Recording

Developing strategies for recording the huge amounts of data that multiple cameras can produce. |

NVIDIA DriveWorks 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.

  • AVDiag 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:

Data Acquisition from Multiple Sensors

Data Acquisition from Multiple Sensors#

Each sensor acquires and transfers the data to one of the processors on the device. Depending on sensor type, the data may first go through a post-processing step (e.g., 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.
