SyncSnap Application
|
|
Overview
SyncSnap application allows you to take synchronized snapshots between cameras connected to the same SoC, such as a Jetson TX1 or Jetson TX2. Syncsnap application uses a client–server model design approach. The application consist of three basic sections:
- A syncsnapd daemon application that runs as a state-machine process for handling snapshots.
- A libsyncsnap library support the IPC to syncsnapd daemon that exposes the available SyncSnap methods.
- A syncsnap example client application which uses libsyncsnap to access the syncsnapd exposed APIs showing how to use SyncSnap
Currently SyncSnap has been tested on TX1 boards configured with up to six cameras taking synchronized snapshots. Other features that are currently under development are:
- Ability to synchronize capture pipelines using a PTP Clock (sync capture between boards).
- A library to integrate calls
- TX2 support
Testing Results
By pointing six cameras into a stopwatch timer RidgeRun has been able to verify that SyncSnap is able to capture synchronized buffers from six cameras:
