BoofCV camera calibration error

Hi, I’m trying to use the camera calibration tool provided by the BoofCV library here, following the tutorial here. My command is as follows:

java -jar applications.jar  CameraCalibration --Camera=0 --Resolution=640:360 CHESSBOARD --Grid=7:5

However, it throws this error when trying to open to webcam for calibration:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

I have found the same solution in many places for this issue (links below), but I have no idea how to change my “class path” or do this thing with maven.

Hi @samuset ,

First of all, are you using Maven (it’s a build system) or do you use Processing?

Also please see : http://www.slf4j.org/codes.html#StaticLoggerBinder

I see that you are running the library with java as a standalone command but not that your issue is not related to Processing and you might want to post on another forum :wink:
