How does the industrial endoscope obtain real-time images of the detected object?

Issue Time:2020-10-15
Industrial endoscopes are actually an application of machine vision technology. Industrial endoscopes can perform regular inspections or body inspections on pipes, container interiors, aircraft turbines, blades, engines, combustion chambers, etc., using machines instead of human eyes. To make judgments and measurements, and through the image capture device to convert the object into an image signal and then through a series of complex processing and finally into a digital signal.
The process of acquiring real-time images of the detected object is the result of comprehensive coordination of multiple technologies. The comprehensive application of computer image processing technology, printing technology, computer network technology, etc. can complete the image capture, storage and processing under the endoscope Analysis, its main working process is as follows:
1. The positioning monitor detects the object and sends a trigger pulse to the image acquisition part.
2. The image acquisition part sends start pulses to the camera and lighting system according to the pre-set procedure and delay.
3. The camera stops the current scan and restarts a new frame scan.
4. Before starting a new scan, open the exposure mechanism and set the exposure time in advance.
5. Another start pulse turns on the lighting. The turn-on time of the light should match the exposure time of the camera.
6. After the exposure, the scanning and output of a frame of image is officially started.
7. The image acquisition part receives analog signals and digitizes them through A/D.
8. The image acquisition part stores the digital image in the memory of the processor or computer.
9. The processor processes, analyzes and recognizes the image to obtain the measurement result or logical control value.
10. The processing result controls the movement of the pipeline, performs positioning, and corrects movement errors.
As a well-known domestic industrial endoscope brand enterprise, JEET Technology focuses on innovation and service, aiming to build a world-class industrial endoscope brand. The company's R&D personnel have gradually developed many new technical products, welcome to come advisory.
