基于形态学重构的实木地板缺陷分割方法研究
Research on Wood Floor Defects Segmentation based on Morphological Reconstruction
摘要
Abstract
Due to the problems of noise existed, time consuming, and lower detection precision in region growth, this paper proposed a novel method using morphological reconstruction technique to conduct on-line defects detection for wood floors. Firstly, this method used two gray thresholds to get two gray images. The lower threshold image was used for seeds optimization, while the higher threshold image was used for seed expansion growth. Skeleton extraction of defects for the lower threshold image was accom- plished by defining corrosion stop criteria. The burr operation was then employed on the lower threshold image to achieve seeds optimization. Secondly, the expansion, holes filling and burr optimization were exerted separately on the high threshold image to accomplish rapid growth of lumber defect area defects extraction. The experiments were carried out in the resolutions of 512 × 512, 256 × 256, and 128× 128, respectively. By contrasting with the traditional region growth method, the tests showed that the proposed method could guarantee the accuracy and the speed for wood floor on-line defects detection.关键词
