Recording Sensor Data

Contents

Section Name	Provides guidance on ...
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 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:

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.
