Claim 2:
3. A system for detecting and evaluating a geometric form of a honeycomb product, configured to implement the method for evaluating the geometric form of the honeycomb product according to claim 2, and comprising:
a placement stage (1) configured to support a honeycomb product (2);
cameras (3) disposed above a top of and on a side of the honeycomb product (2) and configured to acquire an original top-surface image and an original side-surface image of the honeycomb product (2) by shooting the honeycomb product (2);
a camera moving device (4) configured to move the cameras (3) above the top of and at the side of the honeycomb product (2) so that the cameras acquire a complete original top-surface image and a complete original side-surface image;
an analyzing and evaluating module (5) configured to: acquire a top-surface image and a side-surface image by acquiring and performing noise-reduction filtering, binarization and morphological filtering on the complete original top-surface image and the complete original side-surface image; acquire vertex coordinates by extracting vertices from the top-surface image; acquire serial numbers of six vertices of each cell by reconstructing the cells of the top-surface image; compute deviation angles of six interior angles of each cell based on the serial numbers and vertex coordinates of the six vertices of each cell; extract a top-surface side boundary and a side-surface side boundary of the honeycomb product (2) from the preprocessed top-surface and side-surface images; compute a maximum top-surface deflection and a maximum side-surface deflection of the honeycomb product (2) based on the top-surface side boundary and the side-surface side boundary; judge whether the honeycomb product (2) is qualified based on the deviation angles, the maximum top-surface deflection and the maximum side-surface deflection.
