[0002] The technology for detecting air bubbles in concrete is one of the important aspects of concrete quality control, with the aim of ensuring the compactness and strength of concrete.

[0003] Current methods for detecting air bubbles in concrete typically involve using a testing instrument. The instrument's camera takes pictures of the specimen, and the system then analyzes the images to detect air bubbles.

[0004] However, test specimens usually need to be tested on multiple sides. Operators need to turn off the machine, flip the specimens, and adjust their orientation. The whole process is time-consuming and affects testing efficiency. In particular, when multiple specimens need to be tested, operators need to flip the specimens repeatedly, which is quite laborious. Utility Model Content
