![]() ![]() ![]() Before recoding camera data, ensure that the RGB images from the camera is converted into the grayscale format. My camera is on a Raspberry Pi 3B+ and is using s Picamera V2. Collect the IMU sensor’s raw measurement and camera frame for around 60 seconds. I am using ROS Noetic and my server is running on a Ubuntu 20.04 VM. Here is was rosservice list shows: /cv_camera/get_loggers Here is was rostopic list shows: /cv_camera/camera_info Let's list the topics to check that the images are published: rostopic list. Make sure that your stereo camera is publishing left and right images over ROS. The calibration was successful but since then, the camera is not detected anymore by my node or any of the ZED samples/tools. However the distances in a point cloud created by a ROS node I wrote were not correct so I used the ZED Calibration tool to calibrate my camera. We are studying a way to create a plugin for Gazebo and other simulators, but there is not a scheduled timeline for its release. rosdep install cameracalibration rosmake cameracalibration. I have been working with my ZED for a few weeks without any problem. I tried to do the calibration in gazebo and. Yet when I run the calibrator.py script, it fails saying: : wait_for_service(/cv_camera_node/set_camera_info): failed to contact, will keep trying Myzhar August 26, 2021, 12:43pm 2 A lot of users are asking for it, but there is not a simple way to integrate the ZED SDK in a Gazebo plugin using Gazebo virtual stereo image streams as an input. One step of the calibration requires a filteredcloud that is generated from the disparity map of the stereo camera. This issue is not a question, feature request, or anything other than a bug report directly related to this project. Before opening a new issue, please search existing issues. GitHub Preliminary Checks This issue is not a duplicate.I got the cv_camera module to publish the /cv_camera/camera_info, /cv_camera/image_raw I ran rosservice list which showed that the /cv_camera/set_camera_info is running. Unable to open ZED, issue with calibration The LIDARs frames are transformed to match the OCCAM RGB 360 camera. I am new to ROS and am trying to run the camera calibration program. For extrinsic calibration, we use the CAD model provided by the manufacturer of JR2. ![]()
