Download Recorded Sample Data

If you haven’t downloaded the ouster-sdk, please follow the Python Installation instructions.

Download Data

You can download sample data from the sensor documentation by clicking through the Ouster Data App links and using the Download button. After download, you should have two files, a .pcap file and a .json file.

We will use SAMPLE_DATA_PCAP_PATH to refer to this pcap and SAMPLE_DATA_JSON_PATH to this json in the following. You may find it convenient to assign the paths appropriately in your console.

Note

All Ouster sample data is provided under the CC BY-NC-SA license, whether obtained through the above links or from the Ouster website.

Visualize It!

If you’ve installed the ouster-sdk (see Python Installation) then you’re all set to visualize with:

$ simple-viz --pcap $SAMPLE_DATA_PCAP_PATH --meta $SAMPLE_DATA_JSON_PATH

You should get a view similar to:

Ouster simple-viz visualization of OS1 128 Rev 6 sample data

You can control your visualizer with mouse and keyboard:

Keyboard controls:

Key	What it does
o	Toggle on-screen display

m	Cycle point cloud coloring mode
b	Cycle top 2D image
n	Cycle bottom 2D image
R	Reset camera
e/E	Increase/decrease size of displayed 2D images
'/"	Increase/decrease spacing in range markers
w	Camera pitch up
s	Camera pitch down
a	Camera yaw left
d	Camera yaw right
1	Toggle first return point cloud visibility
2	Toggle second return point cloud visibility
0	Toggle orthographic camera
=/-	Dolly in/out
?	Prints key bindings
space	Toggle pause
esc	Exit visualization
./,	Step one frame forward/back
ctrl + ./,	Step 10 frames forward/back
>/<	Increase/decrease playback rate (during replay)
shift	Camera Translation with mouse drag
shift+z	Save a screenshot of the current view
shift+x	Toggle a continuous saving of screenshots
