摘要:
针对安检领域中行李箱内多层物体在二维透视图像中相互重叠,导致物体之间的形状不清晰、不易辨认和存在盲区等问题,提出了一种基于立体匹配技术的分层成像方法.该方法利用双目立体视觉原理,结合双角度投影的灰度信息对投影图像由外向内进行分割,并对分割结果基于相似属性进行匹配,结合视差进行分层重建.最后利用视差原理重建出不同深度的物体,实现了对不同深度物体的识别.经实验验证,该方法有效地消除了视图中的重叠现象,提高了对物体的识别准确率.
Abstract:
In the security inspection field , the multi-layer objects in the luggage overlap each other in the two-dimensional perspective image , resulting in unclear shapes between the objects , difficult to identify,and blind spots．A hierarchical visualization method based on stereo matching technology is clearly proposed．This method uses the basic principles of binocular stereo vision , integrates the gray-level information content of the dual-view projection , performs segmentation of the projection surface image from the outside to the inside , matches the segmentation results according to similar characteristics , and finally integrates parallax to carry out hierarchical build．The key is to use the basic principles of parallax to reconstruct different deep objects and complete the identification of different deep objects．Experiments show that this method reasonably clears the overlap in the main view and improves the accuracy of object recognition．
