Vision Software

Vision software-based devices are employed in a number of industries such as pharmaceutical, food processing, electronics, textile, medical, automotive and automation industries among others where they are programmed to count, measure, inspect or sort objects based on specific features and qualities. Depending on the use and degree of complexity, some software can be embedded in the image capture device while others require more powerful computer processors. When selecting such software it is important to consider the number of images stored and the rate of processing possible with a given program and processes as slow progression or inadequate storage could result in system failure or decreased productivity. Sensitivity, adjustability, dimensions and noise reduction are additional concerns that will vary among software applications.

In addition to the physical and performance specifications, consumers should consider the three main components essential to all vision software. Algorithms are the mathematical equations that are programmed into the software before it is in use. These locate the necessary information based on the goal of the system, be it inspection, counting or measurement. Not just for data collection, these algorithms also interpret, record and respond to the data. The second integral component is the developer or design-time interface. This is where the predetermined criteria is entered by programmers and is often locked to protect the algorithms from unassuming users. A separate interface is available for users. This display is often much simpler and easily understood. Before the output is provided, however, the first step is image manipulation. Depending upon the cameras resolution, most images are first manipulated to reduce noise or convert the colors of shades of gray into a simplified black and white pixilated image. The software then engages the algorithms which perform one or more of the tasks mentioned above. Based on the preset guidelines the part or product is passed or failed. While some systems alert the user in the case of failure, others use a list of connected procedures and the flow of operation is maintained. The high speed, precise and accurate implementation of vision software thusly improves production processes and quality assurance in a broad array of industrial and commercial settings.
