Since the monocularcontains much less depth information, how to recover the camera motion and depth maphas been a difficult problem. Besides, although binocular view contains significant depthinformation, it is difficult to keep the consistency of depth map and moving objectsTherefore, in view of the problems mentioned above the specific research works are asFirst. we introduce two directions of 3D reconstruction in computer vision: based onstereo vision method and based on structure from motion. The stereo matching method hasbcen introduced in detail, including algorithm principle, classification, and evaluationmethod. And, we compare the global, local and semi-global algorithm on four typicaldataset. In addition, we have made a detail introduction of structure from motion(SFM)and the experiment has been carried out to get 3D point cloudSecond, a method for depth map and scene flow estimation is proposed. First, inputbinocular video, initial disparity map is got by SGM, 2 point trajectories are got byoptical flow. Then the 3D tracks are got by disparity map and 2D point trajectories, get theobject motion hypothesis. Considering constraint between the reference image and theforward-backward images, the energy model based on super-pixel and object isconstructed using slanted plane model. Finally, the depth map and scene flow will be gotThird, a method for reconstructing monocular dynamic scene with multiple movingrigid objects captured by a single moving camera is proposed. First of all, feature pointsare matched through the video sequence via the optical flow method and the tracks "aregot based on these matches. Then the tracks are divided into several groups according totheir motion differences. An improved graph cuts based multi-label auto imagesegmentation method is used to acquire the accurate boundary of each moving object and万方数据华中科技大学硕士学位论文the static background. Then we assume a virtual camera for each moving object and thestatic background. The pose of these virtual cameras are estimated via the standardStructure from Motion(SFM) pipeline. Finally a dense point set and textured model isreturned for each virtual camera.
