Building external wall surface spraying method based on visual measurement
The invention relates to a building external wall surface spraying method based on visual measurement. The building external wall surface spraying method specifically comprises the following steps of:1, selecting a calibrated CCD camera and a range finder; 2, connecting the camera and the range finder to a control circuit of the building outer wall spraying robot; 3, shooting a building exteriorwall surface image and measuring the distance from the camera to the building exterior wall surface; 4, enabling the building exterior wall spraying robot to calculate the actual size of the buildingexterior wall surface image according to the distance value from the camera to the building exterior wall surface, the focal length of the camera and the image surface size of the building exterior wall surface image; 5, training a U-Net network; 6, inputting the building external wall surface image into the U-Net network, carrying out image segmentation, and dividing a building external wall surface area needing to be sprayed; and 7, spraying the surface area of the outer wall needing to be sprayed.The method is high in processing speed, small in calculation amount and high in target window contour measurement precision, and the actual construction requirement is well met.
本发明涉及一种基于视觉度量的建筑外墙表面喷涂方法，具体含有以下步骤：1、选择一个标定好的CCD相机和一个测距仪；2、将相机和测距仪连接在建筑外墙喷涂机器人控制电路上；3、拍摄建筑外墙表面图像并测量相机到建筑外墙表面的距离；4、建筑外墙喷涂机器人根据相机到建筑外墙表面的距离值、相机焦距和建筑外墙表面图像的像面尺寸，计算出建筑外墙表面图像的实际尺寸；5、训练U‑Net网络；6、将建筑外墙表面图像输入到U‑Net网络，进行图像分割，划分出需进行喷涂的建筑外墙表面区域；7、对需喷涂的外墙表面区域进行喷涂；本发明处理速度快，计算量小，目标窗口轮廓测量精度高，很好地满足了实际施工需求。
