Object detection method and device |
摘要 |
<p>Disclosed is a method of detecting a to-be-detected object in an image. The method includes steps of receiving the image; extracting an edge in the image; performing segmentation on the edge so as to obtain plural edge segments; obtaining relational data of first and second angles of a sample object in a sample image; for each of the plural edge segments, obtaining an absolute angle and a relative angle associated with the absolute angle, and generating a third straight line from a predetermined point on this edge segment, an angle between the third line and this edge segment being equal to the relative angle; determining one from among intersection points of the third straight lines to serve as a reference point of the to-be-detected object; retaining edge segments whose corresponding third straight lines pass through the reference point; and detecting the to-be-detected object based on the retained edge segments.</p> |
