| 摘 要： | 基于双目立体视觉的植物生长状态无损测量方法研究,能快速地对植株生长进行无损监测,尤其能准确测量倾斜生长的植株高度,对于农业工程研究有重要意义。本研究在实验室搭建计算机双目立体视觉平台,对大豆植株生长进行无损监测。由于植物的形态与生长条件限制,双相机光轴与基线的夹角未能构成最佳双目测量系统,因此本研究对双目立体视觉平台本身的精度进行了校验。利用VC＋＋6.0编制的图像分析处理软件,结合界跟踪算法与斜率计算对植株的顶芽进行识别,能取得很好的效果。研究表明,实验表明双目立体视觉可应用于植物无损监测,具有广阔的应用前景。

| Abstract: | The research of non-destructive measurement which based on the binocular stereoscopic vision can monitor the plant without destruction quickly. Particularly, this means can measure the plant height accurately which is significant to agricultural engineering research. We established the computer binocular stereo vision platform in our laboratory and then used it to monitor the soybean. Since the restricts that limit the morphology of plants and growths which makes the dual camera optical axis Angle with the baseline can never the best binocular measurement system. So we checkout the precision of binocular stereo vision platform .It can take good effect to identify the terminal bud of the plant by using VC＋＋ 6.0, boundary tracking algorithm and slope calculation. The research shows that binocular stereoscopic vision can put into use in non-destructive testing of plant, which has great prospect. |
