基于单目视觉的双机距离检测

Examination of airplane by monocular vision image

本文提出了一种基于单目视觉图像信息估计的3D目标飞机编队的视觉检测方法。若照相机(CCD)焦距已知,且给定飞机的特征形状参数和姿态,可用单目视觉的方法估计长机和僚机之间的距离。在特定的情况下,可以计算出僚机的飞行方向、速度等一系列飞行参数。仿真及结果验证了算法的有效性。

A vision inspection technique is provided, which can be used to examine the distance of the airplanes by its projected image. When the focus length of digital camera is given, with the pose and feature of airplane is also known, their position and/or distance can be estimated using monocular vision image. In specific situation, the orientation and speed of wingman can be calculated. Experiment with simulated data as well as real image is also presented to validate the algorithms.
