Crack observation should measure the distribution position of cracks on the building, the direction, length, width, depth, offset and degree of change of cracks. The number of cracks observed depends on the need, and the main or large cracks should be observed. In order to analyze the causes of cracks and their impact on building safety based on these data, and take effective measures to deal with them in time.

[0003] At present, the crack detection equipment used for engineering quality inspection in the prior art usually contacts the detection equipment with the crack.
