机器视觉检测传感器的工作原理

一说到机器视觉检测传感器,我们都知道它是整个视觉检测系统信息的直接来源,其主要是由一个或者两个图形传感器组成,有时还要配以激光投射器及其他辅助设备。这个东西的主要功能或者说是作用就是获取足够的最原始图像。图像传感器可以使用激光扫描器、面阵CCD工业相机或者TV摄像机,也可以是最新出现的数字摄像机等。

When it comes to machine vision detection sensors, we all know that it is the direct source of the information of the whole visual inspection system. It is mainly composed of one or two graphics sensors, sometimes with laser projectors and other auxiliary devices. The main function of this thing is to get enough of the most original image. The image sensor can use the laser scanner, the array CCD industrial camera or the TV camera, or the latest digital video camera.


机器视觉检测


机器视觉检测传感器是从一整幅图像捕获光线的数以万计的像素。图像的清晰和细腻程度通常用分辨率来衡量,以像素数量表示。在捕获图像之后,机器视觉检测传感器将其与内存中存储的基准图像进行比较,以做出分析。若机器视觉检测传感器被设定为辨别正确地插有八颗螺栓的机器部件,则传感器知道应该拒收只有七颗螺栓的部件,或者螺栓未对准的部件。此外,无论该机器部件位于视场中的哪个位置,无论该部件是否在360度范围内旋转,机器视觉检测传感器都能做出判断。
The machine vision sensor is the tens of thousands of pixels that capture light from an entire image. The clarity and fineness of the image is usually measured by the resolution, and is represented by the number of pixels. After capturing the image, the machine vision sensor compares it with the datum image stored in memory to make an analysis. If the machine vision detection sensor is set to identify the machine parts that correctly insert eight bolts, then the sensor knows that it should reject only seven bolts, or the parts whose bolts are not aligned. In addition, no matter where the machine part is in the field of view, whether the component rotates in the range of 360 degrees, the machine vision sensor can make a judgement.

以上就是关于机器视觉检测传感器的工作原理的基本介绍,更多关于视觉检测方面的知识,请大家关注视觉检测设备厂家创盈时代官网的技术专栏。
The above is the basic introduction of the working principle of machine vision detection sensor, and more about the knowledge of visual inspection.
