Abstract. The ancient city wall contains rich cultural values. Due to environmental and human factors, there are many diseases in the ancient city wall: bulging, cracking, etc., which will lead to the collapse or even death of the ancient city wall. Therefore, the monitoring and protection of the ancient city wall is imminent. This paper proposes a new scheme for bulging monitoring for wall bulging. The feature plane is fitted according to the actual scan data, the degree of bulging, the trend and the area size are determined, and the bulging deformation of the city wall is displayed in the form of an image. Simplify workflow, improve data processing efficiency, and display more intuitively.
