Design of visual inspection scheme for empty wine bottles

Machine vision is to use the photoelectric imaging system to collect the image of the controlled object, digitally processed by a computer or a dedicated image processing module, and identify the size, shape, color, etc. based on the image's pixel distribution, brightness, and color. In this way, the fastness and repeatability of the computer are combined with the highly intelligent and abstract capabilities of human vision, which greatly improves the flexibility and automation of production.
The following figure is the application of pc-based machine vision system in the empty bottle detection system of beer production line. Today, Jingkezhi made this as an example to introduce the functions and selection of various components. The system is mainly composed of six parts including camera, lens, light source, pc platform and control unit. Each part cooperates with each other to finally complete the quality inspection and rejection of wine bottles.

camera
When choosing a camera, there are the following issues to consider:
Resolution: This mainly depends on the shooting field of view and the required accuracy. Of course, when considering the accuracy, you need to make appropriate adjustments based on your own software processing capabilities. Jingke Zhizhi's EM / E series digital industrial cameras include various models from 400,000 to 29 million pixels to choose from. Welcome to contact us.

industrial camera


Frame rate: Calculated based on field of view and speed of movement.

Exposure time: Calculated based on field of view, camera resolution, and motion speed.
Color: Industrial cameras can be divided into black and white and color cameras according to color. If there is no necessary use of color information, it is recommended to use a black and white camera for general inspection to facilitate image processing.

Interface: It is determined according to the transmission distance, the amount of data, and the interface requirements of the host computer.

Lens

 There are several factors to consider when choosing a lens:
    Imaging surface: Whether the imaging surface of the lens matches the ccd camera used.
Lens focal length, object distance, and field of view: This is mainly determined by the actual working or installation environment. The relationship between these parameters is: under the same conditions, the smaller the focal length, the larger the viewing angle, the shorter the minimum object distance, and the larger the field of view. Take three commonly used lenses (50mm, 25mm, 8mm) as an example: the focal length of a 50mm lens is the largest, so the angle of view of a 50mm lens is the smallest, while the field of view is the smallest, and the minimum object distance is the furthest; Secondly, the focal length of the 8mm lens is the smallest, the viewing angle is the largest, and the field of view is the largest, and the minimum object distance is the closest.
