reset camera

[ggsd-ddup]

Hello everyone ！ I have a question about multiple camera such as D435 and T265 ， Someone knows how to restart one of the cameras when they are all running ？

Hi @hfdlwt A C++ hardware reset script at IntelRealSense/librealsense#9287 (comment) will cycle through all attached cameras.

If a specific camera in a set of multiple cameras needs to be reset then IntelRealSense/librealsense#5428 describes how to perform this in Python using a camera serial number.

Thank you for your prompt reply @MartyG-RealSense ，Can the camera continue to work after hardware restart, or does it need to restart the launch file （realsense_camera manger node）

[MartyG-RealSense]

Although a reset will disconnect the camera and then re-connect it, my understanding is that a current session will continue if reconnection is achieved within a time period of 5 seconds. If it takes longer than 5 seconds to re-establish the connection after disconnection then the connection 'times out' (hence the well known error message 'Frame didn't arrive within 5000').

A typical reset of the camera will complete within 3 seconds.

It is certainly possible to reset the camera during a ROS launch without restarting the launch when using the initial_reset:=true parameter.

Thanks again @MartyG-RealSense , Are you talking about manually restarting the camera? What I want is to automatically restart the camera through a trigger condition in the program.

[MartyG-RealSense]

That code will automatically restart the camera when the script is launched. You can though nest a hardware_reset() instruction within an If code block so that if certain conditions are met then the reset command within the If condition is triggered.

Hi @ggsd-ddup Do you require further assistance with this case, please? Thanks!
