Abstract

The invention relates to a method for calculating the area of a building window, and the method comprises the following steps: selecting a window in a building as a calibration window, and performing measuring to obtain the size information of the calibration window; photographing the building by using the unmanned aerial vehicle to obtain a building image; establishing a three-dimensional live-action model by utilizing the building image; intercepting a vertical view of the three-dimensional live-action model to obtain a screenshot image as training data; obtaining a window object detection model through training data training based on an EsyDL platform; obtaining a vertical view of the three-dimensional live-action model as a calculation image; intercepting a calibration window in the three-dimensional live-action model to obtain a calibration image; attaching the calibration image to the edge of the calculation image, and inputting the calibration image into a window object detection model to perform window object detection to obtain all detection windows; and calculating the areas of all detection windows by using the calibration window size information, so the building window area is obtained. According to the building window area calculation method, automatic calculation is achieved, labor is saved, and the calculation efficiency and the calculation precision can be improved.

Description

technical field [0001] The invention relates to the technical field of building window calculation, in particular to a calculation method and system for building window area. Background technique [0002] The window area of ​​the building needs to meet the requirements of the architectural design code, so the corresponding window area size needs to be calculated for the built building. The method of calculating the window area size in the prior art is to calculate the number and type of windows first by calculating manually. And the size, and then calculate the area of ​​a single window, multiplied by the number to get the total window area of ​​the building. However, such a calculation method has a large amount of calculation, and manual calculation is prone to errors, and the error is also relatively large. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, provide a calculation method and system for buil...
