1. Setup#

1.1. System Requirements#

The script can be run on:

Ubuntu 22.04, 20.04 and 18.04. We provide a one-step setup tool to help you simple the installation process of Zed camera’s SDK.

1.2. Run#

Under the main source folder

cd scripts
bash zed_setup.sh

1.3. Show Helps#

cd scripts
bash zed_setup.sh -h

2. Record#

It is capable to check the camera devices connected to the computer autonomously and record multiple cameras in parallel.

import rofunc as rf

root_dir = '/home/ubuntu/Data/zed_record'
exp_name = '20220909'
rf.zed.record(root_dir, exp_name)

3. Playback#

It is capable to check the camera devices connected to the computer autonomously and record multiple cameras in parallel.

import rofunc as rf

recording_path = '/home/ubuntu/Data/06_24/Video/20220624_1649/38709363.svo'
rf.zed.playback(recording_path)

You can save the snapshots as prompted
