1. A method for evaluating a geometric form of a honeycomb product, comprising steps of:
acquiring a top-surface image and a side-surface image of the honeycomb product;
acquiring vertex coordinates by extracting vertices from the top-surface image;
acquiring serial numbers of six vertices of each cell by reconstructing the cells of the top-surface image;
computing deviation angles of six interior angles of each cell based on the serial numbers and vertex coordinates of the six vertices of each cell;
extracting a top-surface side boundary and a side-surface side boundary of the honeycomb product from the top-surface image and the side-surface image;
computing a maximum top-surface deflection and a maximum side-surface deflection of the honeycomb product based on the top-surface side boundary and the side-surface side boundary;
judging whether the honeycomb product is qualified based on the deviation angles, the maximum top-surface deflection and the maximum side-surface deflection;
wherein the step of judging whether the honeycomb product is qualified based on the deviation angles, the maximum top-surface deflection and the maximum side-surface deflection comprises a step of:
judging the honeycomb product as qualified if geometric regularity of the honeycomb product judged based on the deviation angles, the maximum top-surface deflection and the maximum side-surface deflection reaches a preset standard;
wherein the geometric regularity comprises: top-surface cell regularity, side-surface flatness, and top-surface flatness, and
the step of judging the honeycomb product as qualified if the geometric regularity of the honeycomb product judged based on the deviation angles, the maximum top-surface deflection and the maximum side-surface deflection reaches the preset standard, comprises steps of:
