How to use the driver？ #1
Comments
|
Looks like you don't have the binary. Have you successfully compiled the
package?
Is your ROS_PACKAGE_PATH environment variable correct?
(Note that I don't really know the specifics of the package, I just saw
it's a generic error)

try to build it fisrt |
|
I compiled the package, i got error |
|
you should launch the driver as a root due to a bug in the libMVSDK.so |
|
there is a script in the dir "scripts" named run_camera_sudo.sh take a look what it does and modify it to match your installation directory. then it should work |
|
Pro-tip: give the executable root ownership and add the SUID bit so you don't need to do that in the future. # go wherever your binary is
cd your_ws/devel/bin/
sudo chown root:root mv_camera_ros
sudo chmod +s mv_camera_ros |
|
Admin tip: contact driver's support team and ask for a fix. It is not good that app gains more permissions than it actually needs. It is a security rules violation that may lead to undesired behavior. |
|
yes! I did it .but i have a iamge why? |
|
this is caused by the mismatch between number of image channels in the image from driver and its OpenCV wrapper. check for channel number and set it to correct value |
|
I have succeeded！thanks~ Is this driver available on the ARM processor? |
|
I doubt it as the third party folder contains only the x86 64b .so of the
library of the camera.
If you manage to find it for arm, maybe.

I find libMVSDK.so for arm . I can build it . when i run it .i got error |

Well, I guess you should run it on gdb or start adding prints to check out
where it's crashing and fix that cast :)
