摘要:
目前,国内外关于全景相机的应用大部分集中在单视点全景视觉系统,其缺陷是畸变大,在避障中一般不用来测距; 而多目全景相机能够同时获取360°环境的多张图像,通过简易算法实现图像无畸变拼接。针对Ladybug系列相机对多目全景视觉技术在避障测距上的应用开展探索。主要对Ladybug的结构与基本参数、3类坐标系的转换关系、同步获取图像功能进行了研究。最后,利用上述研究获得参数及立体匹配、透视关系计算实际距离。测距结果表明测距误差在可接受范围内。
Abstract:
At present, most applications of panoramic cameras at home and abroad focus on single viewpoint panoramic vision system, the defect of which is the high level of distortion, thus it cannot be used for distance measurement in obstacle avoidance. On the contrary, the multi-view panoramic vision camera can capture multiple images simultaneously in 360°, and these images can be montaged without distortion through simple algorithms. This research firstly explored the application of multi-view panoramic vision technology of Ladybug series into obstacle avoidance and distance measurement, and then mainly studied the structure and basic parameters, the transforming relation of the three coordinate systems in Ladybug series and the function of synchronous image acquisition. Finally, the actual distance was calculated by using parameters gained in the whole process, stereo matching, and perspective relation principle. The final result of ranging shows that the error is within the acceptable range.
