after git clone the repository from Turtlebot3, when i cd catkinws and cmake, screen hang

[timlo94]

first i go cd catkinws/src and i git clone this repository, afterward i cmake and the screen hang directly at 93%. i had perform apt update,upgrade,remove . Even after i reboot the raspberrypi3, i can still run the node with some error. like lane_detection no PYTHON EXTENSION. should be lane_detection.py!!!!

Sorry, first of all, I should change all the python files' name to nonextension. I will update after the modification.

After redownload and compile, it was successful. But after run the intrinsic camera calibration, the display rqt gui dimmed and show nothing, and the launch node cannot be runned due to CVbridge error

[robotpilot]

@ROBOTIS-Leon , We need your guidance about camera calibration and dependency package.

[timlo94]

The display dimmed. This happen during intrinsic camera calibration step : roslaunch turtlebot3_autorace_camera turtlebot3_autorace_intrinsic_camera_calibration.launch

@kijongGil Has this problem been resolved? Please take a look at this issue and add a detailed description of it to e-manual. http://emanual.robotis.com/docs/en/platform/turtlebot3/autonomous_driving/#autonomous-driving

[timlo94]

Not yet solved. It seems like module object has no attribute, CVbridge error simply cannot solve just by downloading the respective dependencies or update/install relevant packages. By the way i am using raspicam, i am not sure whether your cv using usbcam or not.

And also ya, can i know is there other peoples who downloaded this repository also faced same situation? Or developer has tested the code several times before release?.

Thanks a lot for developer, senior research engineer on this matter. Your problem solving skills is appreciated .

Hi and sorry for the late reply. I couldn’t notice that there was some extra questions, since I was in the vacation.

the attached shows something weird; if you ran the catkin make, the opencv bridge must be installed by the joined dependent package. so anyway the error means the cv bridge couldnt be found via python in your computer. try sudo apt-get install ros-kinetic-cv-bridge.

readme.md shows how and what kinda camera should be used for this code. See the description carefully.

There are number of users who ran the code already in their robots. I personally think that you are able to handle

[timlo94]

[timlo94]

My cv bridge is up to date and i had follow readme,just my camera used is normal raspberry pi camera( from official turtlebot)

[timlo94]

Thanks for updating the repository.
