How to calibrate a camera!

##Hey, so you probably stumbled upon this because we have another camera.

That is totally fine. I will do my best to help you get this camera up and running!

##First off, make sure you have a USB driver installed for a camera. If you do not have one installed, I recommend you check out: THIS ANSWER.

You may need to go to the '/usbcam/catkin-ws/src/usb_cam/nodes/usb_cam_nodes.cpp' and modify line 72 to be /dev/video* where the '*' is the camera you are using

Upon doing all of this, you may encounter the following error: 'Webcam: expected picture but didn't get it...' Simply check this link out and it should help: THIS ANSWER

##Now that you have the USB driver installed on the webcam Launch Roscore and

 `$rosrun usb_cam usb_cam_node`

You will now have a topic broadcasting your USBCam if all goes well

##Once you have a USB camera topic running, you can skip to steps 1.3 and 1.4 of the official ROS MonocularCalibration Tutorial
