+(OpenCV Jet). When disabled, the topic continues to publish the raw `16UC1` depth image; the

 ## Supported Devices
 
 Currently, the following devices are supported by the OrbbecSDK ROS2 Wrapper v2-main branch.  More devices support will be added in the near future. If you can not find your device in the table below, try the [main](https://github.com/orbbec/OrbbecSDK_ROS2/tree/main) branch.
