Systems and methods for generating coverage fields for obstacle detection
Systems and methods for generating a coverage field for obstacle detection. The system includes a sensor to detect obstacles. The system further includes a material handling vehicle guided by a guidance system and a controller. The controller is configured to: generate a coverage field for the sensor, receive position characteristics of the material handling vehicle, determine a position of the material handling vehicle relative to the guidance system based on the position characteristics, and transform the coverage field based on the determined position of the material handling vehicle.

5 . The system of claim 4 , wherein the controller is further configured to:
receive a signal representing the distance of the material handling vehicle relative to the fixture within the aisle; and
determine the distance of the material handling vehicle relative to the guidance system based on the signal.
6 . The system of claim 2 , wherein the controller is further configured to:
determine, using the sensor, the distance of the material handling vehicle relative to a fixture within the aisle; and
determine the distance of the material handling vehicle relative to the guidance system based on the determined distance of the material handling vehicle relative to the fixture within the aisle.
7 . The system of claim 1 , wherein the transformed coverage field of the sensor only covers a region of space based on a path of the material handling vehicle.
8 . The system of claim 1 , wherein the sensor is at least one of the group comprising: an image sensor, a LiDAR sensor, and a RADAR sensor.
9 . A method for generating a coverage field for obstacle detection, comprising:
generating, via a controller, a coverage field for a sensor output;
receiving, via the controller, position characteristics of a material handling vehicle guided by a guidance system;
determining, via the controller, a position of the material handling vehicle relative to the guidance system; and
transforming the coverage field based on the determined position of the material handling vehicle.
10 . The method of claim 9 , further comprising:
determining, via the controller, a position of the material handling vehicle based on a parameter, wherein the parameter is at least one of: a speed of the material handling vehicle, a distance of the material handling vehicle relative to the guidance system, or a steering angle of the material handling vehicle.

receiving, via the controller, a signal representing the distance of the material handling vehicle relative to a fixture within the aisle; and
determining, via the controller, the distance of the material handling vehicle relative to the guidance system based on the signal.
13 . The method of claim 12 , further comprising:
detecting, via a second sensor, a distance of the material handling vehicle relative to the fixture within an aisle of the material handling vehicle.
14 . The method of claim 12 , further comprising:
detecting, via the sensor, a distance of the material handling vehicle relative to the fixture within an aisle of the material handling vehicle.
