Description: Patent:SYSTEM AND METHOD FOR 3D OBJECT RECOGNITION. The present invention provides a system and method for recognizing a 3D object in a single camera image and for determining the 3D pose of the object with respect to the camera coordinate system. In one typical application, the 3D pose is used to make a robot pick up the object. A view-based approach is presented that does not show the drawbacks of previous methods because it is robust to image noise, object occlusions, clutter, and contrast changes. Furthermore, the 3D pose is determined with a high accuracy. Finally, the presented method allows the recognition of the 3D object as well as the determination of its 3D pose in a very short computation time, making it also suitable for real-time applications. These improvements are achieved by the methods disclosed herein.

Description: 本文借助于旋转体自身的对称性提出了一种摄像机定位的新算法。此算法所要求的旋转体在日常生活中比较常见。其基本思想主要是通过旋转体的对称特性来寻找物体参考系中的轴方向和轴方向上的消失点,从而估计摄像机的姿态。此算法避免了以往定位所要求的空间几何基元(如点、线等)的精密结构这一难题,通过大量的模拟实验和真实实验验证了此算法的可行性和有效性。可以说此算法是一种比较灵活、简便的定位方法。-A new method for camera pose determination is proposed based on the surface of revolution by using its special symmetry in this paper. The algorithm needs scene which is common in daily life. The basic idea is to determinate camera position by using the symmetry of surface of revolution to find the vanishing point on x axis and z axis of the object reference. This method can avoid the required precise structure of space entities in previous determination approaches. Both synthetic and real data show that the proposed algorithm is feasible and efficient, it can be said that this technique is flexible and easy.

Description: Face recognition [1], the least intrusive biometric technique
in terms of acquisition, has been applied to a wide range
of commercial and law enforcement applications. State-ofthe-
art face recognition systems perform with high accuracy
under controlled environments, but performances drastically
decrease in practical conditions such as video surveillance
of crowded environments or large camera networks. The
main problems are due to changes in facial expressions,
illumination conditions, face pose variations, and presence
of occlusions.

Description: matlab程序。利用二维图像生成3d形状,有原始代码,有测试数据。(We investigate the problem of estimating the 3D shape of an object, given a set of 2D landmarks in a single image.To alleviate the reconstruction ambiguity, a widely-used approach is to confine the unknown 3D shape within a shape space built upon existing shapes. While this approach has proven to be successful in various applications, a challenging issue remains, i.e., the joint estimation of shape parameters and camera-pose parameters requires to solve a nonconvex
optimization problem. The existing methods often adopt an alternating minimization scheme to locally update the parameters, and consequently the solution is sensitive
to initialization. In this paper, we propose a convex formulation to address this problem and develop an efficient algorithm to solve the proposed convex program. We demonstrate the exact recovery property of the proposed method, its merits compared to alternative methods, and the applicability in human pose and car shape estimation.)
