Construction quality intelligent detection method and device

The invention relates to the technical field of quality detection, in particular to an intelligent construction quality detection method and device, and the method comprises the steps: obtaining color image data and three-dimensional point cloud data of a to-be-detected plane based on a binocular camera, carrying out the regional grid division of the detected plane in the color image data, and obtaining a three-dimensional point cloud data of the to-be-detected plane; calculating the pixel coordinates of the grid vertexes and the intersection points in the evaluation area, calculating the variance value of each intersection point relative to the absolute flat plane in the spatial position according to the mapping between the pixel coordinates of the grid vertexes and the intersection points in the area and the three-dimensional point cloud data, and evaluating the flatness level of the to-be-detected plane. According to the embodiment of the invention, on the basis of the three-dimensional point cloud data of
