Abstract: Inresponse to the isues of simple monitoring methods,low efficiency,and the inability toreflect the overall surface deformation of waterproof sealed walls,a monitoring scheme for the deformation of Waterproof sealed walls in underground water reservoirs ofcoal mines is proposed.Based on the principle of binocular positioning,deformationcalculation formulas for single-point protrusion and depresson onthe surface of the sealed wall were provided,along with the calculation logic for three-dimensional cloud map imagingof surface deformation.The cubic spline interpolation method was chosen for interpolation fiting,forming a threedimensional deformation modelof the entire surfaceof the waterproof sealed wall.Anon-contact surface deformation monitoring devicewas designed,which generated structured light images through a light projection module and projected them onto the surface of the waterproof sealed wall.Two light-receiving modules formed a binocular system to receive thereflected structured light images from thesealed wallsurface.These images were thenanalyzed based onthedeformationcalculation logic.Simulation testresults indicated that single-point deformation monitoring and three-dimensional cloud map imaging performed well,efectively reflecting the overall deformation of themonitored objectand enabling timely monitoring of its safety status by management personnel.
