利用旋转双目立体相机的桩体倾斜度测量方法
Pile inclination measurement using a rotating binocular stereo camera
摘要
Abstract
Pile inclination monitoring is crucial in pile sinking operation,and the existing methods generally have typical problems such as complicated placement process and long time-consuming work.Aiming at the above problems,based on the development of binocular stereo equipment,this paper proposes a pile inclination measurement method based on binocular stereo vision.First,the method is realized by rotating the code disk and the camera's high-precision calibration to use the code disk rotation angle readings to efficiently calculate the camera's position information at any rotation angle.Second,under the conditions of simultaneous binocular image acquisition and high-frequency tilt angle measurement,a new method using the extraction of pile body edge geometry is designed to fit the direction vector of the center axis of the pile body,so as to quickly calculate the tilt of the column.The experimental results show that the method can accurately calculate the relative position of the camera and the tilt of the column,and the accuracy of the tilt measurement can reach better than 0.1°,and the efficiency of the single automatic measurement is better than 10 seconds,which is more than 6 times higher than the efficiency of the commonly used total station measurement method,and it can meet the demand for continuous,efficient,and high-precision measurement of the tilt of the pile body.关键词
