Abstract

The invention belongs to the technical field of three-dimensional monitoring and particularly relates to a three-dimensional photographic monitoring method of building deformation.The method includes the following steps that a datum point is set, and coordinates of the datum point in a ground space coordinate system are measured; the position of a monitoring point is determined; the position of an image control point I is determined, and coordinates of the image control point in the ground space coordinate system are measured; an image is acquired, namely the image I is shot; data processing is performed, a three-dimensional model is established to extract the coordinates of the monitoring point in the ground space coordinate system and / or extract a three-dimensional distribution diagram I of the monitoring point.The method can quickly and accurately complete building deformation monitoring.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional monitoring, and in particular relates to a three-dimensional photographic monitoring method for building deformation. Background technique [0002] Seasonal heaving and thawing can change many buildings, especially older ones. In order to predict the changing trend of the building so as to carry out the protection work in the next step, it is necessary to monitor the main structure of the building. [0003] The traditional point monitoring method has a large workload, takes a long time, and cannot fully reflect the deformation characteristics of the monitoring target. The existing laser three-dimensional measurement technology can quickly measure the three-dimensional coordinates of the target object, but the accuracy of this method is not high, it is not suitable for monitoring the deformation characteristics of the target object, and the cost of technical equipment used in this method...
