Abstract
The disclosed embodiment relates to methods for measuring camber on a surface. The method preferably comprises receiving, by a computing device, a plurality of images of a surface, identifying, by a computing device, a key image of the surface from the plurality of images, extracting, by a computing device, a portion of the key image including the surface, and analyzing, by a computing device, the extracted portion of the key image to thereby determine the camber on the surface. The disclosed embodiment also relates to a system and computer-readable code that can be used to implement the exemplary methods.
Claims24
A method for measuring camber on a surface, the method comprising:
- receiving, by a computing device, a video stream of a surface;
- identifying, by a computing device, a key frame of the surface from the video stream by filtering input video frames to identify a candidate image frame using a frame rate of a camera, a speed of a transfer table on which the surface is moving, and a field view of the camera, and by comparing the candidate image frame with a previous key frame by ignoring frames having redundant information;
- extracting, by a computing device, a portion of the key frame including the surface;
- and
- analyzing, by a computing device, the extracted portion of the key frame to thereby determine the camber on the surface.
A system for measuring camber on a surface, the system comprising:
- a computing device configured to receive a video stream of a surface;
- a computing device configured to identify a key frame of the surface from the video stream by filtering input video frames to identify a candidate image frame using a frame rate of a camera, a speed of a transfer table on which the surface is moving, and a field view of the camera, and by comparing the candidate image frame with a previous key frame by ignoring frames having redundant information;
- a computing device configured to extract a portion of the key frame including the surface;
- and
- a computing device configured to analyze the extracted portion of the key frame to thereby determine the camber on the surface.
Computer-readable code stored on non-transitory computer-readable medium that, when executed by a processor, performs a method for measuring camber on a surface, the method comprising:
- receiving, by a computing device, a video stream of a surface;
- identifying, by a computing device, a key frame of the surface from video stream by filtering input video frames to identify a candidate image frame using a frame rate of a camera, a speed of a transfer table on which the surface is moving, and a field view of the camera, and by comparing the candidate image frame with a previous key frame by ignoring frames having redundant information;
- extracting, by a computing device, a portion of the key frame including the surface;
- and
- analyzing, by a computing device, the extracted portion of the key frame to thereby determine the camber on the surface.
