摘要
针对基准平面障碍物检测定位问题,设计了一种采用角度交会法测量二维坐标的嵌入式图像检测系统.二维坐标测量系统采用双线法标定线阵CCD图像传感器,并采用角度交会法对被测对象进行坐标计算,从而测得未修正的二维坐标测量结果.采用控制变量法分别测量X轴和Y轴坐标,使用Matlab软件对数据进行处理,并对X轴和Y轴测量误差分别进行多项式线性拟合,进而得到坐标修正公式,修正的二维坐标误差明显变小.实验结果表明:基于角度交会的二维坐标图像测量系统能够实时、准确、快速和可靠地测量二维坐标,为基准平面障碍物二维坐标测量定位提供了一种可行的方案,具有一定的应用价值和意义.
Abstract
Aiming at the problem of detection and positioning of reference plane obstacles,an embedded image detection system using angle intersection method to measure two-dimensional coordinates was designed.The two-line method was adopted to calibrate the linear array CCD image sensor by two-dimensional coordinate measurement system,and the angle intersection method was used to calculate the coordinates of the measured object,so that the uncorrected two-dimensional coordinate measurement results were obtained.The control variable method was used to measure the coordinates of X axis and Y axis,respectively,the Matlab software was used to process the data,and the polynomial linear fitting of the measurement errors of X axis and Y axis was carried out respectively to obtain the coordinate correction formula,in which the corrected two-dimensional coordinate errors became significantly smaller.The experimental results show that the two-dimensional coordinate image measurement system based on angle intersection can measure two-dimensional coordinates in real time,accurately,quickly and reliably,and provides a feasible scheme for two-dimensional coordinate measurement of reference plane obstacles,which has certain application values and significance.
