The difference between microscope visual observation and computer observation
Today's industry is technologically advanced, and there are more and more computer network devices.
In the past, when we used microscopes, we simply observed the readings with our eyes; then with the development of science and technology, digital display instruments appeared.
With the advancement of science and technology, it is now possible to observe in the computer! Did you know?
For example, a XTL-3400 continuous zoom stereo microscope from Shanghai Jingxian Optoelectronics Technology Co., Ltd. has a standard magnification of 7-45X.
What is the difference between visual observation and computer observation?
1. Visual observation: at most, only the surface magnified to 45 times the size of the detected object can be seen;
Computer observation: To use computer observation, you need to use a camera and a C-mount connected to the microscope (called a camera). It is magnified with the size of the computer screen, we call this magnification "electrical magnification". The total magnification of electric amplification is much larger than 45 times.
2. Visual observation: Long observation time will easily cause visual fatigue and inaccurate observation readings;
Computer observation: Since it is a computer observation, it is a head-up view of the computer screen, which is not easy to cause eye fatigue.
3. Visual observation: It will produce an estimate of the reading of the observed object, which is not accurate;
Computer observation: use the computer to observe, you can use the workbench ruler to calibrate in the computer software first, and then use the simple measurement software that comes with the camera to measure. This is more accurate than visual estimation.
Today's camera function software generally mainly includes three system functions: video processing function, image processing function, and image measurement function.
The video processing function is some processing done on the video stream collected by the camera. It mainly includes the following functions:
1. Real-time video playback, pause and stop functions
2. Automatic white balance, automatic exposure function
3. Video capture function, including static capture, dynamic video recording, timing automatic capture, and original image capture
4. Video parameter setting function (RGB setting, gamma adjustment, exposure setting, offset setting, etc.)
5. Video zoom display and video size control function
6. Video up and down, left and right inversion function
7. Real-time dynamic clear video algorithm
8. Video color and black and white conversion 02165851879
The image measurement function is mainly used in video microscopes. For the pictures collected under different magnifications, this software provides different calibrations respectively. When using it, as long as the corresponding calibration is selected, 02165851879 can directly obtain the actual size of the relevant graphics. This software completes the measurement of the following graphs:
1. Measure the length of a straight line.
2. Measure the side length, area and perimeter of a rectangle.
3. Measurement of half longitude, circumference and area of a circle.
4. Perimeter area measurement of any polygon.
5. Angle measurement.
6. Text input function.
7. Measurement fine-tuning function.
8. Delete primitive function.
9. Mark selection function.
