The design and arrangement of sign on the panel of the surface will become the light spot of the product , which brings brand - new adventure in daily life to users 产品表面标志的设计和排放将成为面板的亮点,给人带来全新的生活体验。
The advantages of the new system over the conventional parallel infrared optical system include higher signal - to - noise ratio , better repeatability and stability , smaller light spot and less energy loss 相对于平行光红外光学系统,会聚光红外光学系统能有效地提高系统的信噪比;膜厚监控稳定、重复性好。
Iris boundary localization based on integral - differential method is modified to improve the localization success rates and the localization speed by eliminating light spots interference and using pupil the position estimation 本文采用亮点梯度检测方法消除光源像点干扰问题,通过瞳孔位置估计提高微积分定位快速性。
The sunlight itseft is not an arealight as the sun is only a small light spot in the sky , compared with the sky . ( the sky is considered as a big dome of an area light ) the sunlight shadow has a sharp edge 阳光本身并不是一种面光,和天空相比,它只是天空中一个小小的光斑罢了(天空可以看作是一个巨大的半球形的面光) 。
Through comparing the distribution of energy in biological tissue generated by single and multi - beam as well as flat and gaussian light , influence of various light sources and the light spot size on the distribution of light absorption is analyzed 通过比较单束以及多束均匀分布光和高斯分布光照射下组织内的光子能量分布规律,分析了不同光源和光斑大小对光吸收分布的影响。
The implementation uses two - dimension images as input . the arrangement of light spots on the lunar rover and the imaging geometry of the camera are used to compute the three - dimension coordinates of the light spots in camera coordinate system , and after transformation , the world coordinate of the light points . we can then easily get the coordinate value of center of mass of the rover after averaging the world coordinate value of light points 本文构造了一种光点配置单目ccd算法,它以计算机视觉系统采集的二维图像信息作为输入,直接利用光点的几何配置条件和摄像机成像几何关系,求解出光点在ccd摄像机坐标系下的三维坐标,并经过坐标变换,转化为在世界坐标系下的坐标,然后取其平均值,从而得出月球车的中心位置。
The light spot image thresholding part of the suite puts forward the iterative algorithm to gain the best threshold by comparing , which could perfectly hold the original image feature . in the extracting the light spot image features part , the algorithms on calculating the coordinates of the " energy distribution barycenter " in the 256 gray levels image and the " geometric - center " in the binary image are adopted respectively and so on 如在对光斑图像进行二值化的过程中,通过比较发现使用迭代法求出最佳阈值的算法能够较好的保留原图像的特征。在对光斑图像进行特征提取的过程中,分别采用了对256级灰度的光斑图像求其“能量分布的重心”坐标;对光斑的二值化图像求其“形心”坐标等算法。
Retinal prostheses currently being developed , for example at the university of southern california , provide what is called phosphene vision ? recipients perceive the world as a grid of light spots , evoked by stimulating the ganglion cells with microelectrodes implanted inside the eye ? and require a wearable computer to process images captured by a video camera attached to the patient ' s glasses 目前研发当中(如美国南加州大学)的人工视网膜,提供的是所谓的光点视觉:透过眼睛里的微电极刺激节细胞,以光点组成的阵列来呈现使用者眼前的世界,但是需要利用穿戴式电脑,先处理使用者眼镜上摄影机拍摄到的影像。
For the reason that this method use the arrangement of characteristic light spot directly to avoid the aberrance that come out during calculating in traditional method , it can improve the estimation precision of position and attitude . besides , it provides a certain degree of redundancy to the visual navigation system 由于该算法直接利用特征光点的几何配置条件,避免了传统算法在计算过程中出现畸变的问题,从而提高了位置和姿态角估值的精度,并使月球车的视觉导航系统具有一定的冗余性。
To fit many good fortune companies , this hometown will be a light spot of development in the future of shenzhen , when favourable climate and geographical position and support of the people this , we is it build domestic most advanced modernization disinfect medicine research and develop the industrial base to prepare actively 安多福公司坐落在深圳东部美丽的南海之滨,这块热土将是深圳未来发展的亮点,趁着这天时地利人和,我们正在积极筹备建设国内最先进的现代化消毒药物研发产业基地。
