Hi, tried to get a executable for "convert_pointcloud_to_image". Already commented in both lines as well as this [Line 223](https://github.com/ros-perception/perception_pcl/blob/e8ce25267a6d9d0bb0d80ba17e9c65269a7254aa/pcl_ros/CMakeLists.txt#L223) but there is no executable after running colcon build. Any suggestions?...

Hi, Basic usage in Ros2: clone package into ros_ws/src and build package with colcon or run apt install ros-humble-pointcloud-to-laserscan ```source /opt/ros//setup.bash``` ```cd ``` ```source install/setup.bash``` ```ros2 launch pointcloud_to_laserscan sample_pointcloud_to_laserscan_launch.py```

Is it possible that this is the pointcloud published by the demo publisher node and for some reason the real input cloud isnt considered as input?

Source cloud needs to be published to /scanner/cloud_in and the dummy pointcloud needs to be deactivated in the launchscript. Finally working!

Thanks for your reply. Thought a bit about it again. I mean as you already have the viewer function using the calibration matrix to project the pointcloud to the image,...

The calibration matrix projects an image point into the lidar 3d point right? With the inverted matrix I should be able to project the 3d lidar point into a 2d...

Hi @koide3, tried to do the projection using cv2. ```import numpy as np import cv2 #saved image from ros image message with shape (1520, 2688, 3) image = cv2.imread("xxx.png") #saved...

Yes, I used this package: https://index.ros.org/p/camera_calibration/github-ros-perception-image_pipeline/#humble with the pinhole argument. The calibration matrix is done with the manual calibration (initial_guess_manual) which was visually better than the fine registration. The automatic...

Hi @surfertas ! After implementing the changes suggested it was a mapping frame error. A static transform publisher solved the problem for me. Also changed setup to Ubuntu 20.04 Ros...
