<jats:p>Architecture is one of the key and important parts of a city. Various kinds of buildings have absolute control over the quantity and area and are the key factors for the appearance of a city. With the development of cities and the increase of population, high-rise residential buildings can effectively alleviate the shortage of urban residential land, but at the same time, it also brings some problems, such as monotonous elevation of high-rise residential buildings, improper selection of elevation forms. As people’s aesthetic awareness is getting higher and higher, people’s requirements for the image of residential buildings are getting higher and higher. However, the research on the elevation design of high-rise residential buildings is relatively lagging behind. Therefore, it is necessary to enrich and expand the elevation design of high-rise residential buildings. Image binarization is an important technology in image preprocessing. It plays an important role in pattern recognition, optical character recognition, and medical imaging. Binary image is a simple image format. It has only two gray levels, but it occupies an important position in the field of image processing. In specific image processing application systems, it is often necessary to obtain binary values. The binary image processing arithmetic is developed from set theory under mathematical morphology. Although its basic arithmetic is simple, it can produce complex results. Based on the characteristics of binary image and the complex effect it produces, this paper finds out its regularity, finds a design method of building elevation, and realizes the application of binary image in building elevation design.</jats:p>
