An underwater three-dimensional point cloud measurement method, electronic device and storage medium |
| abstract |
The invention discloses a binocular vision underwater three-dimensional point cloud measurement method, electronic equipment and storage medium of a sealed water tank device. First, a binocular vision underwater optical measurement system is built; a plane calibration plate is used to perform air calibration on the binocular camera system. , obtain the internal and external parameters of the camera system; build an underwater multi-refractive imaging model, and use the method of combining two sets of cameras inside and outside the sealed water tank to calibrate the spatial position of the refraction plane relative to the camera system in the sealed water tank; the binocular camera system is combined with the guide rail to complete the Image acquisition of the entire surface of the object, and image enhancement and restoration processing of the initial image obtained; The refraction imaging model is used to correct the three-dimensional point cloud; the three-dimensional point cloud data obtained at all measuring points of the binocular camera are unified by using the coding point to realize the optical three-dimensional topography measurement of the surface of the measured object. |
