Publishing static transforms from camera_link provokes NaN values for Femto Bolt

[Danilrivero]

General information

• Ubuntu: 22.04 LTS
• ROS: Humble
• Driver version: 1.58

Explanation

I use the camera for certain detections, all of these are relative to the camera_frame, which need to be transformed to another frame by using tf2. Launching the driver with the following command:

ros2 launch orbbec_camera femto_bolt.launch.py     connection_delay:=500     enable_point_cloud:=true     enable_colored_point_cloud:=true     depth_registration:=true     color_width:=1280     color_height:=960     color_fps:=30     depth_width:=640     depth_height:=576     depth_fps:=30     enable_color:=true     enable_depth:=true     color_format:=RGB888

Provokes the driver publishing the static tf with Nan values, thus giving in another terminal warnings and errors since this other module using the camera information uses tf2 as well.

Error:   TF_NAN_INPUT: Ignoring transform for child_frame_id "camera_accel_frame" from authority "default_authority" because of a nan value in the transform (-nan -0.000000 -inf) (-nan -nan -nan -nan)
         at line 235 in ./src/buffer_core.cpp
Error:   TF_DENORMALIZED_QUATERNION: Ignoring transform for child_frame_id "camera_accel_frame" from authority "default_authority" because of an invalid quaternion in the transform (-nan -nan -nan -nan)
         at line 254 in ./src/buffer_core.cpp
Error:   TF_NAN_INPUT: Ignoring transform for child_frame_id "camera_gyro_frame" from authority "default_authority" because of a nan value in the transform (-nan -0.000000 -inf) (-nan -nan -nan -nan)

Expected output

When launching the driver, it is able to properly calculate the transformations without any problem related to tf2.

Actual output

When testing the latest 1.58 version from 1.57 the following issue arises:

All the topics work as expected and the pcd is being published

• Is there any launch argument I am missing?
• Could it be related to the latest 1.58?

Thanks in advance

Hello,

I have noticed that in some past commits there have been some fixes related to static transforms published such as ee5f7d7. The driver still produces these errors. Is there any information related to this?

Thanks in advance.
