移动高光对三维场景重建的影响与消除
Influence and elimination of moving highlight on three-dimensional scene reconstruction
摘要
Abstract
The scanned image of the smooth ground in the manufacturing workshop had reflection light spot under the irradiation of sunshine or lamplight;and it was varied with the change of the camera shooting position.Based on 3d scene reconstruction procedures and SURF algorithm principle of the Kinect scanning sequence images,influences of mobile highlight reflector on extraction and matching of feature points for reference images and images which are waiting for being matched were analyzed.The experimental result shows that compared with match feature points for the frame image with high reflection,match feature points for the frame image without high reflection is at least higher 8 ％;and remaining match feature points are more after being optimized.In addition,highlight recognition and removal method should be discussed;in terms of grey level images which lack surface texture,based on progressive multilevel threshold and dynamic template,a kind of processing method was proposed;non highlight feature information was not changed;and processing time was saved;recognition and repair were synchronously completed.The experiment shows that in terms of 30m length of sequence image for scene in the workshop which is scanned by Kinect,its light should be repaired by the method proposed in the thesis;and it should be subject to three-dimensional reconstruction;point cloud registration error should be at least reduced by 1Ocm.关键词
