机器视觉这个概念提出至今已有很久历史了,但是真正被大众所认知也是在近几年,随着互联网的发展,机器视觉检测是一个朝阳产业。 通过它与自动化设备相结合,可以为企业产生价值。
The concept of machine vision has been put forward for a long time, but it is widely recognized by the public. In recent years, with the development of Internet, machine vision detection is a sunrise industry. By combining it with automation equipment, it can produce value for the enterprise.

创盈时代作为专业的机器视觉检测设备提供商,接下来为你详细介绍一下机器视觉检测设备的工作过程:


1,首先通过工件检测器检测物体是否接近或运动到摄像机视野的中心,如果是,向图像采集卡发送触发脉冲信号。
1, first, we use workpiece detector to detect whether the object is close to or moving to the center of the camera's field of view, if it is, to send the trigger pulse signal to the image acquisition card.

2,图像采集卡按照设计人员预先设定的程序和延时,分别向摄像机或照明设备发出启动脉冲,但也有摄像机和照明设备在系统初始化话时,就开始启动。
2, the image acquisition card sends the starting pulse to the camera or lighting device according to the preset program and time delay of the designer, but there are also cameras and lighting devices to start when the system initialization.

3,摄像机停止目前的扫描,重新开始新的一帧扫描;有的时候需要摄像机在启动脉冲来到之前一直处于等待状态,启动脉冲到来后启动以帧扫描。

3, the camera stops the current scanning and starts the new frame scanning. Sometimes, it needs the camera to wait in the waiting state until the starting pulse comes. After the start of the pulse, the frame is scanned.

4,如果所采用的策略是曝光策略,那么在摄像机开始新的一帧扫描之前,要打开曝光结构,其曝光时间要根据你的实际需要通过程序或者硬件设定好。
4, if the strategy is exposure strategy, before the camera starts a new frame scan, the exposure structure should be turned on. The exposure time should be set up by program or hardware according to your actual needs.

5,如果采用曝光策略的话,要用另一个启动脉冲打开照明设备,特别要保持启动时间应该与摄像机曝光时间匹配。
5, if we use the exposure strategy, we should use another start pulse to turn on the lighting device, especially to keep the start time match with the exposure time of the camera.

6,摄像机曝光后,正式开始一帧图像的扫描和输出。
6, after the camera is exposed, the scanning and output of a frame of a frame is formally started.

7,如果摄像机输出的是模拟信号,图像采集卡就把从摄像机接受过来的信号进行A/D转化将其数字化,如果输出的是数字信号,这样就省图像采集卡的事情拉。
7, if the output of the camera is analog signal, the image grabber will transform the signal received from the camera to A/D and digitize it. If the output is digital, it will save the image collection card.

8,图像采集卡将图像信号送到缓冲器、处理器或者计算机的内存中,以便图像的处理和显示。
8, the image acquisition card sends the image signal to the memory of the buffer, the processor or the computer, so that the image is processed and displayed.

9,处理器或者计算机对图像进行处理、分析、识别以得到测量结果或逻辑控制量,然后根据这些结果进行处理以控制别的装置(比如机械装置等)来完成相关动作,进行定位。纠正运动的误差等等,比如修正机器手臂的位置。
9, processors or computers can process, analyze and recognize images to get measurement results or logical control quantities, and then process them based on these results to control other devices, such as mechanical devices, to complete related actions and locate. Correction of motion errors, such as correction of the position of the robotic arm.
