工業(yè)內窺鏡就是機器視覺技術的一種應用,利用機器代替人眼來做判斷和測量,適用于難以觀察到的場合.機器視覺指的是用機器代替人眼來做測量和判斷.通過圖像攝取裝置將被攝取轉換成圖像信號,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,轉變成數(shù)字化信號.它的主要工作過程是:
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)測器探測到物體,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定的程序和延時,向攝像機和照明系統(tǒng)發(fā)出啟動脈沖.
2. The image acquisition part sends the start pulse to the camera and lighting system according to the preset program and delay
3、攝像機停止目前的掃描,重新開始新的一幀掃描.
3. The camera stops the current scan and starts a new frame
4、在開始新的掃描之前要打開曝光機構,事先設定曝光時間.
4. Before starting a new scan, turn on the exposure mechanism and set the exposure time in advance
5、另一個啟動脈沖打開燈光照明,燈光的開啟時間應該與攝像機的曝光時間匹配.
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通過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算機的內存總.
8. The image acquisition part stores the digital image in the processor or computer memory
9、處理器對圖像進行處理、分析、識別,獲得測量的結果或者邏輯控制值.
9. The processor processes, analyzes and identifies the image to obtain the measurement result or logic control value
10、處理結果控制流水線的動作、進行定位,糾正運動的誤差等.
10. The processing results control the movement of the pipeline, position, correct the error of movement, etc
