These studies have been conductedusing non-metric digital camera and dense image matching algorithms, as non-contact methods of creating monuments documentation.In order toprocess the imagery, few ope...
Intensity images acquired with range imaging instruments can be used in the future for various applications, e.g. face recognition, assisting blind people in travelling and walking, automatic robotic ...
Due to the intense vibration and/or the change of space environmental factors such as temperature, pressure, etc., the stellar camera parameters might change during satellites launching or while orbit...
为了满足人们的多元化通信需求,构建可靠的低成本通信链路,本文利用日常生活中的屏幕显示设备和照相摄像设备,构建了新型Display-to-Camera通信系统.描述了系统基本链路并建立系统模型,阐述了收发机实现框架和关键技术;搭建实验系统,设计了符合显示屏显示特性的新型彩色条码流,用以承载信息;接收端利用计算机图像处理技术,匹配、跟踪识别信号区域,过滤系统背景噪声;利用帧分类和颜色增强技术抑制了系统...
Image-based modeling techniques are an important tool for producing 3D models in a practical and cost effective manner. Accurate image-based models can be created as long as one can retrieve precise...
针对当前工业相机和图像采集卡Camera Link标准接口需要使用专用集成电路才能实现的问题,提出采用最新Xilink的Virtex5系列现场可编程门阵列 (field programmable gate array, FPGA),使用甚高速集成电路硬件描述语言(very high speed integrated circuits hardware description language, V...
Nowadays lidar and photogrammetric surveys have been used together in many mapping procedures due to their complementary characteristics. Lidar survey is capable to promptly acquire reliable elevation...
Digital photogrammetric products from the integration of imagery and lidar datasets are a reality nowadays. When the imagery and lidar surveys are performed together and the camera is connected to the...
Camera motion analysis (CMA) is very useful for many video content analysis tasks, but few works competently handle the videos with significant camera or object motion. In this paper, we present an e...
High-speed digital cameras are progressing rapidly with the development of CMOS image sensor in these few years. In order to develop a high-speed CMOS industrial digital camera, the CMOS image sensor ...
