Title:
LINE SEGMENT DETECTION METHOD AND APPARATUS, DEVICE, AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/042866
Kind Code:
A1
Abstract:
The present invention provides a line segment detection method and apparatus, a device, and a computer-readable storage medium. The method comprises: extracting image features of an image to be treated, the image features comprising an image gradient angle and an image gradient amplitude; determining a plurality of seed points on the basis of the extracted image features; for each seed point in the plurality of seed points, determining a current connection region of the seed point according to a region growth rule, where the region growth rule needs to satisfy both a gradient amplitude growth rule and a gradient angle growth rule; and performing line fitting on line segments in the current connection region of the seed points.
