Abstract

The invention provides a method and a device for estimating window areas. The method comprises the following steps: acquiring a building image acquired by an image acquisition device; wherein the building image comprises a window with an area to be estimated and a reference object with a known size, and the reference object is attached to the wall surface of the building; processing the building image, and determining a bounding box of the window in the building image and a bounding box of the reference object in the building image; and determining the estimated area of the window according tothe size of the reference object, the window and the boundary frame of the reference object. Compared with a traditional method for measuring the area of the window on site, the method provided by the invention has the advantages that the area of the window is estimated quickly, simply and conveniently in a non-contact mode, the working efficiency is improved, and the operation difficulty and theoperation cost are reduced.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method and device for estimating window area. Background technique [0002] While railway, highway and air transportation are convenient and fast, they also bring noise pollution. In order to reduce the impact of noise pollution on related populated areas along the line, noise can be reduced by setting up sound barriers. [0003] Due to the limitation of the location of the sound barrier and its technical characteristics, after the noise reduction measure of the sound barrier is adopted, the high-rise buildings and remote building areas in the relevant areas along the traffic facilities are still in a high-noise environment, and the noise reduction control indicators cannot be achieved. At this time, it is necessary to install soundproof windows outside the windows of such buildings that cannot meet the noise reduction control indicators, so as to reduce the...
