工業(yè)內(nèi)窺鏡就是機(jī)器視覺(jué)技術(shù)的一種應(yīng)用,利用機(jī)器代替人眼來(lái)做判斷和測(cè)量,適用于難以觀察到的場(chǎng)合.機(jī)器視覺(jué)指的是用機(jī)器代替人眼來(lái)做測(cè)量和判斷.通過(guò)圖像攝取裝置將被攝取轉(zhuǎn)換成圖像信號(hào),傳送給專用的圖像處理系統(tǒng),根據(jù)像素的分布、亮度、顏色等一些信息,轉(zhuǎn)變成數(shù)字化信號(hào).它的主要工作過(guò)程是:
Industrial endoscope is an application of machine vision technology. It uses machine instead of human eye to make judgment and measurement, which is suitable for difficult to observe occasions. Machine vision refers to using machine instead of human eye to make measurement and judgment. Through the image capture device, the captured image is converted into image signal, which is transmitted to the special image processing system. According to the distribution of pixels, brightness The main working process is as follows
1、定位監(jiān)測(cè)器探測(cè)到物體,想圖像采集部分發(fā)送觸發(fā)脈沖.
1. The location monitor detects an object and sends a trigger pulse to the image acquisition part
2、圖像采集部分按照事先設(shè)定的程序和延時(shí),向攝像機(jī)和照明系統(tǒng)發(fā)出啟動(dòng)脈沖.
2. The image acquisition part sends the start pulse to the camera and lighting system according to the preset program and delay
3、攝像機(jī)停止目前的掃描,重新開(kāi)始新的一幀掃描.
3. The camera stops the current scan and starts a new frame
4、在開(kāi)始新的掃描之前要打開(kāi)曝光機(jī)構(gòu),事先設(shè)定曝光時(shí)間.
4. Before starting a new scan, turn on the exposure mechanism and set the exposure time in advance
5、另一個(gè)啟動(dòng)脈沖打開(kāi)燈光照明,燈光的開(kāi)啟時(shí)間應(yīng)該與攝像機(jī)的曝光時(shí)間匹配.
5. Another start pulse turns on the light. The time of the light should match the exposure time of the camera
6、曝光后,正式開(kāi)始一幀圖像的掃描和輸出.
6. After exposure, the scanning and output of a frame of image is started
7、圖像采集部分接收模擬信號(hào)通過(guò)A/D將其數(shù)字化.
7. The image acquisition part receives the analog signal and digitizes it by a / d
8、圖像采集部分將數(shù)字圖像存放在處理器或者計(jì)算機(jī)的內(nèi)存總.
8. The image acquisition part stores the digital image in the processor or computer memory
9、處理器對(duì)圖像進(jìn)行處理、分析、識(shí)別,獲得測(cè)量的結(jié)果或者邏輯控制值.
9. The processor processes, analyzes and identifies the image to obtain the measurement result or logic control value
10、處理結(jié)果控制流水線的動(dòng)作、進(jìn)行定位,糾正運(yùn)動(dòng)的誤差等.
10. The processing results control the movement of the pipeline, position, correct the error of movement, etc
