Abstract
An method for automatically panning a view for a commercial vehicle includes analyzing a portion of a first view at a first time to determine a position of a vehicle feature within the first view, wherein the first view is a subset of a second view, estimating an expected position of the vehicle feature in the first view at a second time subsequent to the first time, defining a region of interest centered on the expected position of the vehicle feature in the second view and analyzing the region of interest to determine an exact position of the vehicle feature at the second time, and determining a current trailer angle based on a position of the vehicle feature within the second view.
Claims20
A method for automatically panning a view for a commercial vehicle comprising:
- analyzing a portion of a first view at a first time to determine a position of a vehicle feature within the first view, wherein the first view is a subset of a second view;
- estimating an expected position of the vehicle feature in the first view at a second time subsequent to the first time, wherein the expected position is determined using a kinematic model of vehicle reversing combined with sensor data;
- defining a region of interest centered on the expected position of the vehicle feature in the second view and analyzing the region of interest to determine an exact position of the vehicle feature at the second time;
- and
- determining a current trailer angle based on a position of the vehicle feature within the second view.
A camera mirror system for a vehicle comprising:
- a first camera having a first field of view;
- a controller configured to receive the first field of view and output a subset of the first field of view to a first display;
- and
- the controller configured to determine a two dimensional trailer angle based on a position of a vehicle feature in the first field of view at a first time, estimate an expected position of the vehicle feature in the first field of view at a second time subsequent to the first time, wherein the expected position is determined using a kinematic model of vehicle reversing combined with sensor data, convert the two dimensional trailer angle to a three dimensional real world trailer angle, and adjust the output subset of the first field of view based on the three dimensional real world trailer angle.
