8. Multi-Camera
Synchronization
Using an 8-pin connector and matching cable, a multi-camera and
multi-sensor network can be designed. Recommended minimum delay
setting is 4ms (please follow the instruction in the SDK).
*The Pin sequence is shown with
camera placed in bottom view.
• Increase camera coverage in the given space and ll in the
occlusions where a single camera may have blind spots.
• Capture multiple images of the same scene and scan
objects from different angles.
• Increase the effective frame rate to greater than 30
frames per second (FPS).
Advantages of a multi-camera setup
Pin Denitions Description
Pin_1 VCC The default is 1.8V.
When 3.3V or 5V drive voltage is provided on
the VCC interface, the I/O level setting can be
adjusted to 3.3V or 5V as required
Pin_2 GPIO_OUT Reserved GPIO with low level outputs
Pin_3 VSYNC_OUT Synchronous trigger signal: Active high.
The high level provides the triggering signal
for the secondary devices.
Pin_4 TIMER_SYNC_OUT Pulse signal source, reset hardware
timestamp of secondary devices.
Pin_5 RESET_IN Hardware reset signal: Triggers the camera
to power down and automatically power up
and reset.
Detect the input signal: 20Hz / 50% duty
cycle / more than 5 consecutive cycles, that
is, judged as normal input signal, other
signals ltered out; allowed uctuations for
frequency ± 1Hz, duty cycle ± 2%.
Pin_6 VSYNC_IN Synchronous trigger signal: Active high.
Generated for the triggering/sync signal by
the primary device, with a duration of 1ms.
Pin_7 TIMER_SYNC_IN Hardware timestamp reset signal input,
hardware timestamp clearing
Pin_8 GND Ground
Synchronization Interfaces of Astra 2 Camera
Multi-camera and multi-sensor synchronization in different
congurations can be designed with the optional Orbbec Multi-Camera
Sync Hub Dev and Multi-Camera Sync Hub Pro accessories.
9. Safety and
Handling
1. Follow the camera operation instructions. Improper operation
may cause damage to internal components.
2. Do not drop or subject the camera to external force.
3. Do not attempt to modify the camera as modications may
cause permanent damage or inaccuracies.
4. The camera temperature may increase during long periods
of continuous usage.
5. Do not touch the lens. Fingerprints on the lens may affect
image quality.
6. Keep the product beyond the reach of children or animals to
avoid accidents.
7. If the camera is not recognized by the computer, check if
the cable meets the power/data transfer requirements and
reinsert the USB for reconnection.
8. This product uses a Class 1 laser. Looking at the laser for
more than 20s is not recommended.
