Abstract
Pantograph identification methods and devices including computer-implemented methods, software, computer systems for identifying a pantograph of an electric vehicle represented in an image captured by a camera. The method includes, for each pair of adjacent edges represented in the image, determining distances between the adjacent edges, wherein the distances are in a same direction for each of the distances. Then determining a point weight for points of the image associated with the distance by comparing the distance to a value or a value range representing a dimension of the pantograph. Further determining a region of the image that represents the pantograph based on the point weights.
Claims13
A computer-implemented method for identifying a pantograph represented in an image comprised of points, the method comprising:
- for each pair of adjacent edges represented in the image, determining a plurality of distances between the adjacent edges, wherein the plurality of distances are in a same direction;
- for each of the plurality of distances, determining a point weight for points of the image associated with the distance by comparing the distance to a value or a value range representing a dimension of the pantograph;
- and
- determining a region of the image that represents the pantograph based on the point weights.
A computer system for identifying a pantograph represented in an image comprised of points, the computer system comprising:
- a memory to store instructions;
- a bus to communicate the instructions from the memory;
- a processor to perform the instructions from the memory communicated via the bus
- for each pair of adjacent edges represented in the images, to determine a plurality of distances between the adjacent edges, where the plurality of distances are in a same direction;
- for each of the plurality of distances, to determine a point weight for points of the image between the adjacent edges in the same direction by comparing the distance to a value or a value range representing a dimension of the pantograph;
- and
- to determine a region of the image that represents the pantograph based on the point weights.
