LAYERED SOIL SETTLEMENT MONITORING SYSTEM AND METHOD BASED ON MACHINE VISION

WIPO Patent Application WO/2024/083272

A1

A layered soil (7) settlement monitoring system and method based on machine vision. The method comprises: arranging, at intervals, multiple layers of target media on the cross section of soil (7) to be subjected to monitoring; repeatedly collecting position information of the multiple layers of target media by means of a visual sensor (4); performing comparison to obtain position change parameters of each target medium at different moments; and performing calculation to obtain a relative layered settlement amount of each layer of the soil (7). The monitoring system comprises a measurement sleeve (1), a sliding rail system (2), a target medium injection system (3), a visual sensor (4), a power source module (5), a stabilized-pressure engagement and fixation device (8), etc. The visualized monitoring of a layered settlement condition of soil (7) is realized by means of a single measurement drill hole (11), thereby improving the monitoring accuracy and efficiency; and the monitoring system has relatively strong universality and adaptability, and is thus applicable to layered settlement monitoring of different types of soil (7).
