Foundation pit multi-measuring-point integrated monitoring method based on monocular vision
A foundation pit multi-measuring-point integrated monitoring method based on monocular vision comprises the steps that (1) a foundation pit is surveyed, and the positions of a monitoring point and a working base point are selected; (2) selecting camera and lens parameters, and constructing a synchronous monitoring system; (3) arranging a measuring point target, pouring a working base point camera monitoring pier, installing a camera group and light supplementing equipment, determining a background marker and arranging a calibration target; (4) calibrating an inertial measurement unit (IMU), and adjusting the poses of the target and the camera by using the IMU; (5) preheating the camera, setting shooting frequency, and continuously monitoring the measuring point target in real time; (6) dividing an image region of interest, positioning target pixels, and resolving square target angular points in real time; (7) for the initial frame image, calculating the corresponding proportionality coefficient of each target, and resolving the initial coordinates of each measuring point and each calibration point; and (8) for each subsequent frame, calculating the coordinates of each measuring point and the calibration point to obtain the noise displacement of the measuring point, and calculating the displacement of the background static marker to obtain the denoising displacement of the measuring point.
