  "textContent": "A method for calibrating extrinsic parameters () of a trailer camera () supported by a trailer () attached to a tow vehicle (). The method includes determining a three-dimensional feature map () from one or more vehicle images () received from a camera () supported by the tow vehicle and identifying reference points () within the three-dimensional feature map. The method includes detecting the reference points within one or more trailer images received from the trailer camera after the vehicle and the trailer moved a predefined distance in the forward direction. The method also includes determining a trailer camera location () of the trailer camera () relative to the three-dimensional feature map () and determining a trailer reference point () based on the trailer camera location. The method also includes determining extrinsic parameters () of the trailer camera relative to the trailer reference point.",
