Abstract To solve the problem that the digital image recognition accuracy of
concrete structure cracks is not high under the condition of uneven illumination
and complex surface color of concrete structure, this paper has proposed a block
segmentation method of maximum entropy threshold based on the digital image
data obtained by the ACTIS automatic detection system. The steps in this research
are as follows: 1. The crack digital images of concrete specimens with typical features were collected by using the Actis system of KURABO Co., Ltd., of Japan in
the concrete beam bending test. 2. The… More >
