NVIDIA Jetson TX2 with two 18 Mpix USB cameras - results¶
Test results from two Subminiature cameras attached to Jetson TX2¶
Due to increasing demand towards miniaturization and mobility of vision systems, XIMEA decided to test a stereo combination of two 18 Mpix USB3 cameras attached through a carrier board to a SoC (system on a chip) kind of GPU module from NVIDIA.
The carrier in this case has two separate USB3 controllers.
The main components¶
SoC - NVIDIA Jetson TX2
Carrier board - J121 from Auvidea
2x 18 Mpix cameras - mini camera from XIMEA
2x USB3 cables - Type-C connectors
2x S-mount lenses - M12 lenses from Lensation
The processing pipeline¶
- image acquisition,
- auto exposure,
- auto white balance,
- rendering on a screen (60Hz).
One MU181 camera:
- Full frame 4896x3680 at 8bit was 22fps with 160ms G2G (glass to glass) latency
- 2x2 binning 2448x1842 at 8bit resulted in 60fps and 90ms G2G latency
Two MU181 cameras:
- Full frame 4896x3680 for both cameras at 8bit was 10fps with 190ms G2G
- 2x2 binning 2448x1842 for both cameras at 8bit resulted in 30fps and 100ms G2G
Other processing modes available¶
- 10/12bit acquisition and processing,
- h264/h265 encoding (for 4096x4096 images max, 8/10 bit),
- RTSP streaming (after encoding),
- Recording to disk in RAW, DNG, h264/265, other formats.
