I also added the following line in the roboInit method per instructions based on a previous post:
Code:
System.load("/usr/local/lib/lib_OpenCV/java/opencv_java2410.so");
I double checked multiple times that this path was correct. |
This may be due to the robotInit() method being called a short period of time after the robot code actually starts.
You can put the System.load(PATH); line inside of a static initialization block in the main robot class.
It should look something like this, but with CV_PATH replaced by the path you installed to. It can be inserted above your robotInit() method.
Code:
static {
System.load(CV_PATH);
}
