1. A method comprising:
receiving an image of a roadway recorded by a camera device installed within a vehicle;
detecting a horizon line in the image;
overlaying a line on the image to generate an overlaid image;
transmitting the overlaid image to a computing device over a network;
receiving a modification of the line from the computing device, the modification comprising a new line at a second position;
computing a camera parameter based on the new line; and
transmitting data representing the camera parameter to the camera device.
