法国L-acoustics线阵的应用,用过的进来讨论的相关文章

基于FPGA的线阵CCD图像测量系统研究——笔记

---恢复内容开始--- 本文是对基于FPGA的线阵CCD图像测量系统研究的阅读笔记 读了前面的摘要依然没有看懂作者要做什么.接着往下读.... 终于看到了一个字眼“基于机器视觉的图像测量技术”,看来我可以在这个方面找找文献了. 不同于大多数光电器件以电流或者电压为传感信号,CCD是以电荷为信号把一副空余分布的图像变为一列按时间域离散分布的电荷信号. 非接触式的快速精确测量 ---恢复内容结束---

线阵相机镜头和光源选型

 关于线线相机.镜头.光源的选型,欢迎来电探讨线扫描系统的搭建与选型      随着机器视觉的大规模普及与工业流水线速度.精度的提高,线扫描系统越来越被视觉工程师和最终用户所认可. 首先,我对线扫描系统做一个大致的介绍.线扫描系统用于被测物体和相机之间有相对运动的场合,通过线扫描相机高速采集,每次采集完一条线后正好运动到下一个单位长度,继续下一条线的采集,这样一段时间下来就拼成了一张二维的图片,也就类似于面阵相机采集到的图片,不同之处是高度可以无限长.接下来通过软件把这幅“无限长”的图片截成一定

线阵相机与面阵相机的区别

线阵相机 主要应用于工业.医疗.科研与安全领域的图象处理. 在机器视觉领域中,线阵相机是一类特殊的视觉机器.与面阵相机相比,它的传感器只有一行感光元素,因此使高扫描频率和高分辨率成为可能.线阵相机的典型应用领域是检测连续的材料,例如金属.塑料.纸和纤维等.被检测的物体通常匀速运动 , 利用一台或多台相机对其逐行连续扫描 , 以达到对其整个表面均匀检测.可以对其图象一行一行进行处理 , 或者对由多行组成的面阵图象进行处理.另外线阵相机非常适合测量场合,这要归功于传感器的高分辨率 , 它可以准确测量

东芝线阵CCD芯片TCD1305DG驱动时序设计

最近在做微型光谱仪,用到了东芝的CCD芯片TCD1305DG,该芯片是单行3648像素,输出信号是时间上离散的模拟信号,典型输出速率为0.5M,即每2000ns输出一个像素值(模拟信号),芯片内部集成了相关双采样电路,直接输出稳定的像元电压值,而不是传统的三阶梯信号.TCD1305DG需要三路驱动信号,分别是主时钟CLK,移位输出信号SH,积分清除信号ICG,芯片手册上给出的时序波形如下: 图1 TCD1305DG驱动时序 该CCD的基本工作原理如下:光敏元接收外部光信号并将其转换为电荷储存在光

线阵相机参数计算,选择合适的相机与镜头

1.精度=物宽/像素,此公式用来选相机. 如要求精度为0.3mm/pixel,物体宽1200mm,那么像素就是4K,所以选择4K相机. 2.物体最大移速=精度×最大行频,此公式用来计算相机是否满足移动速度. 0.3mm/pixel×26000Hz=7617mm/s,即物体移速低于457m/min即可,所以选的4K相机没有问题. 3.物距=焦距×精度/像元尺寸,此公式用来选择镜头或计算物距. 像元尺寸要查产品手册,如5×5um2 ,那像元尺寸就是5×10-3 mm. 所以,物距=焦距×0.3/0.

空间谱专题00:综述

作者:桂. 时间:2017-08-21  06:45:55 链接:http://www.cnblogs.com/xingshansi/p/7402353.html 前言 打算梳理一下空间谱的算法,开设一个专题. 按照目前的考虑,主要着要点包括: A-信号模型 即信号的基本模型,因为最基本的信号从波动方程而来,进一步才有近场以及远场近似.在窄带中经常假设包络基本不变,这些假设合理之处都要从信号的基本模型出发来理解. B-空间谱的意义 空间谱建立在传统的Beam-forming(波束形成)的基础上,
