摘要:

双目立体视觉测量技术用于机场场面的目标监视,关键是对具有相同特性的目标进行正确的像素点匹配。提出用SIFT算法获得目标的粗匹配点并用极线约束方程剔除目视误匹配点的方法,达到正确像素点匹配的目的。方法应用表明,在SIFT粗匹配的基础上利用设定临界阈值的极线约束方程能消除目视误匹配点。

Abstract:

The binocular stereoscopic vision technology could be used to locate targets on an aerodrome. To ensure positioning targets,the pixels on images from two vision sensors should be matched precisely. Combining with the advantage of SIFT and an epipolar line constraint equation,a method of pixel matching is proposed. Using this method,it can not only ensure the accuracy of target matching,but also automatically find out the feature point of aircraft which is useful for position and calculation.

Key words: surveillance, binocular stereoscopic vision technology, SIFT, epipolar line constraint, threshold
