Abstract

A method for detecting dimension of box based on depth map includes: receiving a depth map generated by a camera, the depth map corresponds to pixels of an image including a box; performing a coordinate transformation to transform the depth map into camera coordinates of each of the pixels; dividing some of the pixels into plural blocks, each of blocks includes a number of the pixels adjacent to each other; statistically analyzing an average normal vector of each of the blocks according to the camera coordinates of the pixels of each of the blocks; classifying the blocks into plural clusters according to the average normal vector of each of the blocks; performing a plane extraction to obtain edge vectors according to plane formulas of the clusters; obtaining vertexes of the box according to the edge vectors; and obtaining a dimension of the box according the vertexes.
