Update HemiStereo software

Updates for the HemiStereo software on the sensor device are packaged in the HemiStereo SDK installation on your host machine. To get device updates, you have to install the latest version of the HemiStereo SDK or upgrade the already installed version using the maintenancetool executable in the installation directory.
When everything is up-to-date, open the HemiStereo Viewer application. The HemiStereo Viewer will search for devices and check for updates. If any update is available, the update button next to the device entry becomes orange:

After clicking the button, a dialog appears which displays some information about the available updates.

To update the device, just click on the Update button at the bottom of the dialog. The update tool will upload the packages and install them on the device. After updating, the status message of each package should show “Up-to-date”.

If anything went wrong, please contact support@3dvisionlabs.com.


  • In older devices, the HemiStereo SDK was installed under /opt/osp. In current releases, the SDK is installed under /opt/3dvisionlabs/hemistereo. Please adapt your library search path if you have custom software running on the device.
