二维图象 meaning in Chinese
two dimensional image
Examples
- Camera calibration is a critical step in computer vision , through which 3 - d information can be extracted from 2d images
摘要相机定标是计算机视觉中的关键步骤，通过相机定标可以从二维图象序列中获取物体的三维信息。 - 3d points are converted to images based on spherical polar coordinates , and point cloud surface information such as location , normal and color are stored in two - dimensional images
本文通过球面极坐标将点云曲面的几何信息及表面属性信息映射到二维图象中去。 - Modeling : this thesis develops a method different from traditional techniques that begins with the cylindrical projection of a generic model and its seamless global texture map using multiresolution technique , and then automatically fit the unwrapped cylindrical projected mesh to the texture map with an improved algorithm that based on 2d morphing to specify corresponding feature points ( or lines ) . finally , we propose a formula of inverse cylindrical projection to recompose the deformed mesh , and after the texture mapping a photo - realistic individual facial model is created
采用多分辨率技术构造纹理无缝拼接图，然后把三维网格模型投影到圆柱面上并展开，根据二维图象变形技术中特征点匹配算法的数学思想，将匹配公式进行改进后应用于模型网格点的适配，在作了一定假设后推导出逆向圆柱映射的计算公式，再将适配后的柱面网格映射回去，最后进行纹理映射生成真实感的特定人脸的三维模型。 - The computer aided medical image 3 - d - reconstruction technologies - - medical visualization is one of the most active fields of scientific visualization . it reconstruct 3d - regular data sets conies from the ct , mri or slice to 3d - image which can be viewed interactively on the screen . the technologies has a great significant in medical teaching , medical diagnosis n therapy planning and telemedicine
计算机辅助的医学图象三维重建技术? ?医学可视化是科学计算可视化的一个具体应用，也是科学计算可视化的最活跃的领域之一，它运用计算机图形学和图象处理技术将来源于ct 、 mri 、生物组织切片等医学二维图象数据重建成三维图象，在屏幕上显示出来并可以进行交互处理。 - Some by - products of this work can be used as routine tools in the uv laser laboratory . commercial video ccd cameras are used to image uv laser and soft x rays , window glass as a fluorescer is used to indirectly measure the uv laser beam profile with high energy density , and a special glass which permits uv light to pass through while absorbs the visible , is introduced into the uv beam profiling in strong visible stray light environment
实验中发展了一些测量技术，例如用可见光视频ccd直接测量紫外激光的光束分布和激光等离子体产生的x光二维图象，利用窗玻璃作为荧光体测量能量密度较高的紫外光束分布，利用可见吸收紫外透射玻璃制成的衰减器测量有严重背景光的紫外光束分布，可以作为实验室的常规测量工具，并有一定的推广价值。
