Regional feature extraction method and device based on architectural drawing, and computer equipment

The invention relates to a regional feature extraction method and device based on an architectural drawing, computer equipment and a storage medium. The method comprises the following steps: acquiring a building graphic design drawing; the trained region extraction model is utilized to extract region key points of each region in the architectural graphic design drawing, and the region key points comprise corner points of the regions; connecting the key points of each region according to a preset specified sequence to obtain plane information of each region; and outputting plane information of the region through the region extraction model. The method can improve the extraction accuracy of the target area of the architectural drawing. 本申请涉及一种基于建筑图纸的区域特征提取方法、装置、计算机设备和存储介质。所述方法包括：获取建筑平面设计图纸；利用训练好的区域提取模型，提取建筑平面设计图纸中各区域的区域关键点，区域关键点包括区域的角点；对各区域关键点按照预设指定顺序进行连接，得到各区域的平面信息；通过区域提取模型输出区域的平面信息。采用本方法能够提高建筑图纸目标区域提取准确性。
