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.
Two-dimensional coordinate image measurement system based on angle intersection
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.
