When I tried the ros package under /Software, its process dies immediately, with the output like this: NODES / ocams_1cgn (ocams_1cgn/ocams_1cgn) ocams_base_link (tf2_ros/static_transform_publisher) ocams_camera_link1 (tf2_ros/static_transform_publisher) ocams_camera_link2 (tf2_ros/static_transform_publisher)

Is there a reason why the process dies? I did not modify the source code. Maybe there is a bug somewhere.

Please let us know your development environment, such as OS and ROS version. Our code was tested on Ubuntu 16.04 with ROS kinetic version.

TomLBZ commented 4 years ago

I am developing on Ubuntu 18.04 LTS with ROS melodic.

I have the same exact setup and problem:

The program appears to be crashing on line 656 of oCamS.cpp: https://github.com/withrobot/oCamS/blob/master/Software/oCamS_ROS_Package/ocams_1cgn/src/oCamS.cpp#L656

CS-WITHROBOT commented 4 years ago

The code was verified with the following tool sets.

ubuntu 16.04 LTS
ROS kinetic
openCV 3.3.0

If you can, please try to run it in those environment.

arkorobotics commented 4 years ago

@CS-WITHROBOT Would it be difficult to update the example code to support the following?

Ubuntu 18.04
ROS Melodic
OpenCV 4.0

I ask because I'm trying to use this camera for an AI race car and the best computer I could find that fits within the volume/power constraints is the Nvidia Jetson Nano. Unfortunately, to take full advantage of the hardware I need to run OS/ROS/OpenCV versions mentioned above.

I found other stereos cameras that integrate well with the Nano, but none of them are global shutter and color! It's clear that oCamS is the better hardware choice, but without a working ROS examples, it's going to be a time sink for us to debug and update the code

Any chance we can get the examples updated to Melodic/OpenCV 4?

I noticed that the "oCamS_Linux_ParameterControl_Example" can handle OpenCV 4 which is great, so I'm hopeful that your team can update the ROS and People Counter example code.

@arkorobotics If you send us your email address to withrobot@withrobot.com, we can send you a revised code which we will upload to github eventually.

Thank you for using our product.

when you install the image_geometry ros module, libopencv_flann.so.3.2 and libopencv_imgproc.so.3.2 are installed automatically.

And it causes a crash with the opencv 4 library. So you have to remove libopencv as below command and fix something in the oCamS code.

$ sudo apt remove libopencv*

Fixed points.

CMakeLists.txt
package.xml
oCams.cpp Find the word 'image_geometry' and please comment out. And should be replaced 'image_geometry::StereoCameraModel::MISSING_Z' to '10000' in the oCamS.cpp

After then, catkin_make and try run it.

위에 알려주신 조치후에 카메라 화면은 나오기 시작했습니다... 위에 주석처리로 인해서 //#include <image_geometry/stereo_camera_model.h> 부분을 주석 처리하여 문제가 발생 하는것 같습니다. 해결 방법은 없는지요 ??

그리고 카메라 화면이 녹색 필터 처리한것처럼 나오는대 정상인가요 ??
