Description
Technical Field
The invention relates to the technical field of mechanical and electronic compass measurement and SfM-MVS three-dimensional point cloud model correction, in particular to mechanical and electronic compass auxiliary gesture-determining equipment for gesture measurement.
Background
The attitude data (mainly the azimuth angle and the inclination angle of a plane) is important spatial information, the attitude of a certain target plane can be uniquely defined, the intersection azimuth of the target plane and the horizontal plane is the trend of the target plane, and the included angle of the target plane and the horizontal plane is the inclination angle of the target plane. Although with the progress of remote sensing technology, the three-dimensional point cloud can be used for measuring the occurrence of occurrence, the method is only suitable for an environment with good RTK-GNSS signals, and in a measuring environment with the RTK-GNSS signals incapable of being received or weak signals, the three-dimensional point cloud is required to be used for posture correction. Therefore, compass yield measurements of the object planes in the scene are of particular importance. However, in the field geological formation measurement, a formation plate is often required due to the uneven structure surface, and the formation plate is often replaced by a hard skin recording book. In practice, the notebook may move and rotate during the measurement of the inclination angle, the posture is not fixed, and the measured attitude is not accurate. Some formation faces are not exposed and difficult to measure, and a small sheet is required to be inserted into the gap for measurement. Meanwhile, when the mobile phone electronic compass measures, besides overcoming the problems encountered in the measurement of a mechanical compass, a leveling instrument is needed for posture determination. Otherwise, the measured trends are incorrect without the initial calibration, nor are the apparent trends and apparent tilt angles meaningful.
The development of the point cloud technology enables the geological field working mode of the modern structure to be divided into two processes, firstly, the point cloud data acquisition is carried out on site aiming at the ground object, and the complete point cloud data record is provided; and secondly, a programmable information extraction process can be built indoors. Therefore, it is particularly important to obtain three-dimensional point cloud data with accurate posture and size. At present, the correction method of the three-dimensional point cloud comprises a GCP method and a GCPL method, and experiments prove that in the GCPL method, the exposed structural surface is uneven so that the exposed structural surface cannot be used for correcting the posture of the point cloud, therefore, auxiliary equipment with size scales and capable of determining the posture is required to be placed in the scene in advance for the point cloud correction, and otherwise, the size and the posture of the point cloud cannot be determined.
Therefore, the invention provides a novel mechanical and electronic compass auxiliary attitude determination device for attitude measurement.
