The application discloses a book self-service returning sorting method and device based on side edge spine
feature extraction, relates to the technical field of book management, and synchronously collects spine side edge images through at least three imaging units arranged on both sides and above a book bearing platform, respectively acquires a front
view angle image, a left tilt
view angle image and a right tilt
view angle image of a spine; detects a probability clue of the existence of a text line from a structure enhanced image, constructs a text line manifold field and tracks a manifold curve; meanwhile, a binding texture direction field is constructed based on a
structure tensor; a cooperative energy function is constructed through joint text line manifold field and texture direction field, a spine center line is self-organized and fitted in an
energy minimization mode, and left and right boundary curves of the spine are deduced to generate a spine
mask image. Through multi-view
image acquisition and cooperative
processing, the spine region segmentation model is constructed by combining the text line manifold field and the texture direction field, the accurate extraction of the spine region is realized, and the accuracy of
feature extraction is improved.
