【摘要】 介绍了基于双目立体视觉的秧苗直立度自动测定硬件系统和软件系统组成。在移栽机试验台上 ,两摄像机经标定后获取秧苗图像 ,通过图像处理得到二值化秧苗图像 ,在二维图像空间将秧苗角度信息简化为一条直线 ,然后利用简化的两条已知直线与两摄像机参数矩阵 ,进行空间直线三维重建 ,完成秧苗直立度的测定。试验结果表明 :该方法可以获得较高的精度。更多还原

【Abstract】 An automatic measuring system of seedling perpendicularity based on binocular stereo vision was discussed. On a transplanting test bed,seedling images were acquired through two cameras calibrated. Using image processing technique,the angle information of seedling is represented by a line of two dimensional space. Through reconstruction of the line in three dimensional space based on the parameters from two cameras and the lines,the measurement of seedling perpendicularity was completed. The experiments revealed that a better precision could be obtained by this method.更多还原
