Modeling camera Image Formation Using a Feedforward Neural Network

2013年教育技术与管理科学国际会议

作者： YangNa Su Department of Education HanShan Teachers’ University

For the shortcomings of integrity, fixity and closed of traditional courseware, for the purpose of improve the reuse, versatility and openness of courseware, this paper use Flash ActionScript 3.0 technology, develop a set of generic courseware integrableware system, and base on the system construct a intelligent, high degree of simulation of the virtual video camera system. The virtual video camera system has the functions of record, zoom and play, and virtual the advance features such as zebra pattern, white balance, etc. It represents the development direction of intelligent simulation and integrableware applications.

Open Journal of Applied Sciences 2013年第1期3卷 75-78页

One fundamental problem in computer vision and image processing is modeling the image formation of a camera, i.e., mapping a point in three-dimensional space to its projected position on the camera’s image plane. If the relationship between the space and the image plane is assumed to be linear, the relationship can be expressed in terms of a transfor-mation matrix and the matrix is often identified by regression. In this paper, we show that the space-to-image relation-ship in a camera can be modeled by a simple neural network. Unlike most other cases employing neural networks, the structure of the network is optimized so as for each link between neurons to have a physical meaning. This makes it possible to effectively initialize link weights and quickly train the network.

第三届中国卫星导航学术年会

作者： Shuang Du, Bei Huang, Yang Gao Geomatics Engineering, The University of Calgary, 2500 University Dr, N.W., Calgary, Alberta, Canada

Pedestrian navigation remains a difficulty in the navigation community, especially for the indoor environment. Previous research demonstrated that the integration of camera and IMU is able to provide the navigation information in indoor environment. In this research, we employ the iphone4 from Apple Inc. as the platform for pedestrian indoor navigation. The iphone4 contains a 5-megapixel camera, threeaxis accelerometers and three-axis gyroscopes. The Allan Variance method will be employed in this paper to characterize various types of error terms in both the accelerometers and gyroscopes. This process will generate new knowledge on the Smartphone inertial sensor errors. A tightly coupled integration algorithm is implemented using an extended Kalman filter to fuse the image data and the inertial data to derive the optimal navigation solution. The vision aiding information will be retrieved from successive images captured by the iphone4 camera with a frame rate, such as 25Hz. A standard computer vision algorithm will be adopted for image features detection and matching. An indoor field test is conducted to evaluate the navigation performance of the proposed algorithm. The results demonstrate significant improvement on the navigation performance of the proposed system comparing to the stand-alone INS.
