Hello,

I'm using Intel Realsense R200 camera and Realsense ROS SDK. When I run realsense_r200_launch.launch, I encountered following error.

[ERROR] [1446254837.488498054]: DSAPI call failed at /home/turtlebot/catkin_ws/src/realsense_ros/src/r200_camera_nodelet.cpp:509! status:  DS_FAILURE details: Internal exception: Failed to grab the Z frame hit return to exit

Any comment would be appreciated.

Hi Tom, I post sample messages above.

Hi,

There is no filtered odometry from robot_localization when I put visual odometry as an input. Interesting thing is that robot_localization successfully produces a filtered odometry when I put wheel odometry instead of visual odometry. Both visual odometry and wheel odometry uses same ros message (i.e. nav_msgs/Odometry). The launch file is follows.

<node pkg="robot_localization" type="ekf_localization_node" name="ekf_localization" clear_params="true">

  <param name="frequency" value="20"/>
  <param name="sensor_timeout" value="0.1"/>
  <param name="two_d_mode" value="true"/>

  <param name="map_frame" value="map"/>
  <param name="odom_frame" value="odom_combined"/>
  <param name="base_link_frame" value="base_footprint"/>
  <param name="world_frame" value="map"/> 


  <param name="transform_time_offset" value="0.0"/>

  <param name="odom0" value="/visual_odometer/odometry"/>  

  <rosparam param="odom0_config">[true, true, false,
                                  false, false, true,
                                  false, false, false,
                                  false, false, false,
                                  false, false, false]</rosparam>

  <param name="odom0_differential" value="false"/>

Any comments would be appreciated.

I solved this problem by replacing "TransformTFToEigen" and "TransformEigenToTF" with "transformTFToEigen" and "transformEigenToTF" respectively. Please see https://github.com/tum-vision/dvo/iss... .

I have met the same problem. The header file is included in the code. How can I solve this problem?

Hi,

I wonder how to implement auto integration time in SR_3D_View of SwissRanger. Even though I looked the API functions, I couldn't find a proper API function. The API includes only SR_GetIntegrationTime() and SR_SetIntegrationTime().

Any comment would be appreciated.

Best, Soonhac

I solved this issue by installing nvidia-glx-96.^^

Hope it would be helpful.

Hi,

I encountered the following errors on running the tod_stub.

$ rosrun tod_stub detector -B t0001.bag

X Error of failed request: BadAccess (attempt to access private resource denied) Major opcode of failed request: 155 (GLX) Minor opcode of failed request: 26 (X_GLXMakeContextCurrent) Serial number of failed request: 72 Current serial number in output stream: 72

Any comment would be appreciated.

Thank you, Soonhac
