Randomly with a picture, from the picture we can see very intuitively,
A sensor in the detection of the bottle, triggered a photographic signal to the capture card.
A camera, under the illumination of the light source, receives the photo command from the capture card,
takes a picture of the bottle, and gets the image data of the bottle.
This data can be saved as a picture and put on the disk for subsequent use,
it can also be directly processed by the additive in the memory.
The so-called processing is to perform feature enhancement, blob analysis, and other analysis of the image.
The image is then processed by a camera, which can be used as a signal to take a photo of the bottle.
The so-called processing is a series of operations such as feature enhancement, blob analysis, AOI extraction, and so on,
to determine whether the bottle is defective or not, and whether it is full of liquid and other production requirements.
This is a complete vision inspection system.
This is a complete vision inspection system.
The main components include: 1, light source. 2, camera. 3, capture card. 4, computer. 5. image processing software.
But in the actual design or application, the composition of the vision system does not have a unified standard.
For example, the light source can be omitted without.
For example, the camera and capture card are integrated into the camera.
For example, the camera, the capture card, the computer, and the software are all integrated together for you in a smart camera.
The above should provide a more intuitive understanding of the visual inspection system.
2. CCD
As for the front of a CCD, just contact with the vision, off the mouth said CCD is also quite high,
think CCD is industrial vision, in fact, just a sensor device.
The imaging sensor material in the lens is divided into CCD and COMS,
but now we will choose more CMOS cameras, performance can be used cheaper.
Here is an excerpt of the meaning of these two abbreviations.
CCD: Charge Coupled Device image sensor,
CMOS: Complementary Metal-Oxide Semiconductor,
the same as CCD, the same as in the camera can record light changes. CMOS: Complementary Metal-Oxide Semiconductor
I hope this helps,
As for the visual processing software,
I will also share the tutorials on how to get started later,
welcome to pay attention to the exchange of Oh.
CCD machine vision inspection is to use the machine to replace the human eye to do some judgment and measurement work.
Precisely machine vision positioning inspection, the vision system refers to the machine vision equipment that is the image ingestion device, the target to be photographed into image information.
In the transmission to the specialized image processing system, according to the distribution of pixels, brightness and color information, transformed into digital signals, the image system in these signals to carry out a variety of operations to extract the characteristics of the target, and then according to the results of the judgment to control the scene of the equipment to carry out a series of operations.
At present, it has been widely used in electronics, packaging, printing, chemical, food, plastic, textile and other industries.
At present, the domestic visual inspection companies do more, Shenzhen has a full emperor technology can also be, especially the software strength is very strong, a day to detect up to tens of thousands of, do the range is quite wide, greatly reducing labor costs.
Visual inspection is to replace the human eye with a machine to do the measurement and judgment. Visual inspection refers to the machine vision products (i.e., image acquisition device, CMOS and CCD two kinds) will be taken into account the target into an image signal, transmitted to the special image processing system, according to the pixel distribution and brightness, color and other information, into digital signals; image system of these signals to carry out a variety of operations to extract the characteristics of the target, and then according to the results of the discrimination to control the scene of the equipment action. The system is used for production, assembly, or packaging. It is a valuable mechanism used in production, assembly or packaging. It is invaluable in the function of detecting defects and preventing defective products from being distributed to consumers.
