The Importance Of Machine Vision Light Sources In The Visual System
Total Articles: 98
It is an indispensable part of the machine vision system, and its choice directly affects the quality and application effect of the input data. Since there is no universal machine vision lighting device, for each specific application example, the corresponding lighting device should be selected to achieve the desired application effect.
The[url=https://www.honoroptics.com/purchase-high-purity-optical-grade-sapphire-optics/]wholesale large size optical grade sapphire optics[/url] is one of the most critical parts of the machine vision system and is directly related to the success or failure of the system. A good lighting design allows us to get a good image, which improves the resolution of the entire system and simplifies the calculation of the software. Unsuitable lighting can cause many problems.
The role of [machine vision light source]:
1. Illuminate the target and increase the brightness
2. Used as a tool or reference for measurement
3. Overcoming ambient light interference to ensure image stability;
4. Forming an effect that is advantageous for image processing;
In the visual project, how can I choose the ideal lighting scheme? In this process, we need to consider many factors, such as the direction of [url=https://www.honoroptics.com/customizable-infrared-silicon-lenses/]wholesale large size infrared Silicon optics[/url], the size of the light source, the shape, the installation space requirements, the intensity of the light, the polarization, the uniformity of the light, the diffused light or the parallel light, the background of the target, etc., using the light source The color, color temperature, target size, working distance, emission angle, and light-emitting device are also factors to be considered.
At the heart of the machine vision system is image acquisition and image processing. The quality of the image itself is critical to the overall vision system. [Machine Vision Light Source] is an important factor in determining the image quality of the entire machine vision system. By selecting an appropriate light source, the target features and background information in the image can be reasonably separated, thereby greatly reducing the difficulty of image processing and improving the system. Stability and reliability.
In machine vision systems, the more common visual light sources are high-frequency fluorescent lamps, fiber-optic halogen lamps, xenon lamps, and LED light sources. LED light sources are more commonly used, and occupy a dominant position in the field of machine vision [url=https://www.honoroptics.com/high-quality-lisaf-lisgaf-and-licaf-laser-crystals/]wholesale LiSAF, LiSGaF and LiCAF laser crystals[/url], becoming the preferred light source for machine vision system integration.
In the visual system, an effective lighting idea can be established to quickly evaluate which light source can effectively solve the lighting problem. According to the basic information of the object to be tested, the installation conditions, etc., it is pre-determined which light source illuminates the target area to be bright or dark, which can better implement the software algorithm.
