机器视觉技术,是一门涉及人工智能、神经生物学、心理物理学、计算机科学、图像处理、模式识别等诸多领域的交叉学科。机器视觉主要用计算机来模拟人的视觉功能,从客观事物的图像中提取信息,进行处理并加以理解,最终用于实际检测、测量和控制。 什么是工业相机? 工业相机是机器视觉系统中的一个关键组件,其本质功能就是将光信号转变成有序的电信号,相当于机器视觉系统的“眼睛”。相比于传统的民用相机(摄像机)而言,工业相机(摄像机)具有高图像稳定性、高传输能力和高抗干扰能力等,市面上工业相机大多是基于CCD(Charge Coupled Device)或CMOS(Complementary Metal Oxide Semiconductor)芯片的相机。 CCD,电荷藕合器件图像传感器。它使用一种高感光度的半导体材料制成,能把光线转变成电荷,通过模数转换器芯片转换成数字信号,数字信号经过压缩以后由相机内部的闪速存储器或内置硬盘卡保存,因而可以轻而易举地把数据传输给计算机,并借助于计算机的处理手段,根据需要和想像来修改图像。


CMOS,互补性氧化金属半导体。和CCD一样,同为在数码相机中可记录光线变化的半导体。CMOS的制造技术和一般计算机芯片没什么差别,主要是利用硅和锗这两种元素所做成的半导体,使其在CMOS上共存着带N(带–电) 和 P(带+电)级的半导体,这两个互补效应所产生的电流即可被处理芯片纪录和解读成影像。


工业相机的作用 工业相机一般安装在机器流水线上代替人眼来做测量和判断,通过数字图像摄取目标转换成图像信号,传送给专用的图像处理系统,图像系统对这些信号进行各种运算来抽取目标的特征,进而根据判别的结果来控制现场的设备动作。 随着国内机器视觉行业的迅猛发展,机器视觉系统的重要组件,工业相机也同样得到了巨大的发展。数字工业相机对被摄物的大小没有限制,根据镜头的条件,既可以拍摄一般物质,也可以用于显微镜摄影。目前,工业相机的主要用途包括以下几个方面: (1)在开发产品和验证产品等:如开发金属材料及树脂材料时,用来观察材料受到冲击时内部裂纹产生的方向、状态等,可用来分析材料被破坏时物质的结构,及电子产品的工业在线检测等。 (2)包装和标签行业的印刷过程中,能够实时检测到高速印刷中细微的缺陷,以便采取措施,减少损失。常见的缺陷如划痕、灰尘、漏印、墨痕、褶皱等都可被检测出来,提高投资回报,减少废品支出,提高了客户满意度和信任度。 (3)其他领域:如机器视觉、科研、军事科学、航空航天等众多领域,尤其是在智能交通行业:超速抓拍,闯红灯电子警察、高速路口、卡扣收费等交通行业也得到了良好的使用。 工业相机的分类 企业在实际选购和使用工业相机之前,首先需要确定的就是相机的类型。下面是按照不同的行业标准进行的工业相机分类。 (1)芯片类型 分为CCD相机、CMOS相机; (2)传感器的结构特性 分为线阵相机、面阵相机; (3)按照扫描方式 分为隔行扫描相机、逐行扫描相机; (4)分辨率大小 分为普通分辨率相机、高分辨率相机; (5)输出信号方式 分为模拟相机、数字相机; (6)输出色彩 分为单色(黑白)相机、彩色相机; (7)输出信号速度 分为普通速度相机、高速相机; (8)响应频率范围 分为可见光(普通)相机、红外相机、紫外相机等。 工业相机为什么会丢帧? 选择合适的相机也是机器视觉系统设计中的重要环节,相机的选择不仅直接决定所采集到的图像分辨率、图像质量等,同时也与整个系统的运行模式直接相关。设计不良的驱动程序或工业相机硬件可能会造成丢帧,其原因就是资料通道的堵塞,无法及时处理,所以新的图像进来时,前一张可能被迫丢弃,或是新的图像被迫丢弃。要解决这问题,需要设计者针对驱动程序与工业相机硬件资料传输的每个环节进行精密的设计。 智能相机与工业相机 智能相机(Smart Camera)并不是一台简单的相机,而是一种高度集成化的微小型机器视觉系统。它将图像的采集、处理与通信功能集成于单一相机内,从而提供了具有多功能、模块化、高可靠性、易于实现的机器视觉解决方案。同时,由于应用了最新的DSP、FPGA及大容量存储技术,其智能化程度不断提高,可满足多种机器视觉的应用需求。 工业相机与智能相机的应用场合相差不大,但使用上却有很大的差别,工业相机需要外接控制器,需要专业性比较强的软件人员来进行编程,可应对各种复杂的检测要求,而智能相机则内置简单实用的调试工具,可以独立工作而不需要外接控制器,操作简单,容易上手。ABB LGR 分析仪的优势之一在于其稳定性和便携性,这两个关键特点解释了为什么许多客户将它们用于各种机载操作。不少机载飞行监测温室气体的科学研究成果已在一些科学家撰写的论文中发表。




相比CRDS技术,LGR 专利的第四代离轴积分腔输出光谱技术(OA-ICOS)不需要实现亚纳米级的光路对准,且不需要昂贵且复杂的减振或外部压力稳定方案,即可在飞行期间提供出色的数据。ABB基于北斗卫星导航系统的ABB Ability™天然气泄漏检测车载版与无人机版解决方案,在往届中国进口博览会上成功首发后,已为中国众多城市提供了高精准燃气管网检测服务。去年,ABB又推出了“ABB全域多维立体温室气体监测管家系统”,基于多种光学吸收原理,广泛应用于从太空到陆地、从固定污染源到大气环境站、从点式到线面测量,提供 “天-地-太空” 高密度立体监测技术,精准量化来自城市、工业、基础设施和农业等各类温室气体的源汇贡献,为国家“双碳”目标落地提供告价值的基础数据与领先的技术支撑在机载式应用中,除了此次珠峰科考所采用的直升机载温室气体监测解决方案外,ABB在2018年推出了全球第一款高精度轻型无人机载温室气体分析系统。

Machine vision technology is an interdisciplinary subject involving artificial intelligence, neurobiology, psychophysics, computer science, image processing, pattern recognition and many other fields. Machine vision mainly uses computer to simulate human visual function, extracting information from images of objective things, processing and understanding, and finally used in actual detection, measurement and control. What is an industrial camera? Industrial camera is a key component of machine vision system. Its essential function is to transform light signal into orderly electrical signal, which is equivalent to the "eye" of machine vision system. Compared with the traditional civilian camera (camera), industrial camera (camera) has high image stability, high transmission capacity and high anti-interference ability, etc. Most industrial cameras in the market are based on CCD(Charge Coupled Device) or CMOS(Complementary Metal Oxide Semiconductor) chips. CCD, electrically coupled device image sensor. It USES a high sensitivity of semiconductor, can convert light into electrical charges, through the adc chip is converted into digital signals, digital signals by the camera's internal flash memory after compressed or built-in hard disk card preservation, thus it can be easily transmit the data to a computer, and with the help of the computer processing method, according to the need and imagination to change the image.




CMOS, complementary metal oxide semiconductor. Like CCD, a semiconductor that records changes in light in digital cameras. The manufacturing technology of CMOS is no different from that of ordinary computer chips. The semiconductor is mainly made of silicon and germanium, so that the semiconductor with N(band - charge) and P(band + charge) level coexist on the CMOS. The current generated by the two complementary effects can be recorded and interpreted into images by the processing chip.




The role of industrial camera Industrial camera is usually installed on the machine assembly line instead of the human eye to do measurement and judgment, by digital image intake target into image signal, and send it to the dedicated image processing system, image system of the signals for a variety of operations to extract target feature, and according to the results of determination to control the scene of the equipment. With the rapid development of domestic machine vision industry, the important component of machine vision system, industrial camera has also been a huge development. Digital industrial cameras have no limit on the size of the subject, and can be used for either general matter or microscope photography, depending on the lens conditions. At present, the main purpose of the industrial camera including the following aspects: (1) in product development and validation of products such as: such as development and resin materials, metal materials used for observing material impact on the direction of internal crack, status, etc., can be used to analysis the structure of the material was damaged when the material, and electronic products, such as industrial online detection. (2) In the printing process of packaging and label industry, it can detect subtle defects in high-speed printing in real time, so that measures can be taken to reduce losses. Common defects such as scratches, dust, missing prints, ink marks, wrinkles, etc. can be detected, increasing the return on investment, reducing waste expenditure, and improving customer satisfaction and trust. (3) Other fields: Such as machine vision, scientific research, military science, aerospace and many other fields, especially in the intelligent transportation industry: speeding capture, red light electronic police, high-speed intersections, card charge and other traffic industries have also been well used. Before the actual purchase and use of industrial cameras, enterprises first need to determine the type of camera. The following is a breakdown of industrial cameras according to different industry standards. (1) Chip type is divided into CCD camera and CMOS camera; (2) The structural characteristics of the sensor are divided into linear array camera and planar array camera; (3) According to the scanning mode, it is divided into interlaced scanning camera and progressive scanning camera; (4) The resolution
