Keyence designs CV-X series control to make vision systems more simple to implement and operate
1 min read
The Keyence CV-X Series control aims to simplify the process of vision system implementation and operation. All tools have been categorised by application and every screen has an intuitive menu with an on-screen guide, designed not only to assist set-up but also to enhance the user's understanding of the processes behind the tools.
The full range of Keyence tools, still readily available, ensures that the CV-X can claim to be a full blown vision system not just a vision sensor, confirms the company.
The CV-X series now comes with automatic measurement set-up. The user chooses the type of measurement required, clicks the points to measure between and the device automatically defines the position and size of the inspection areas, optimises the settings to pick up on the correct features and performs the calculation.
Targets are identified by Keyence's shape detection algorithm, ShapeTrax2, allowing for multiple stable inspections to be undertaken whatever the product position. Inspection accuracy is maintained down to sub-pixel levels, even using 5 million pixels per image, claims the company.
Once the camera is in position on the line, by simply running 30-50 good products, checking for shape, colour and pattern, the standalone CV-X Series system's auto tech capabilities 'learn' the acceptable manufacturing tolerances. By recognising similarities between non-defective parts, rather than differences in defective parts, the stability of the inspection is greatly increased.
The CV-X100 vision system is equipped with a suite of tools designed to make image capture more reliable. Among them is a tool to ensure that the image capturing conditions (camera position, lighting, focus) remain
constant. In the event of variation, an assistant guides the user in a few clicks to recreate the original capturing conditions.
The CV-X Series is capable of using digital correction to remove the effects of curved or slanted surfaces due to camera installation and/or lens distortion. The result of this digital correction is an image identical to one taken from the perspective of a camera positioned right above the target. This function is particularly useful where robots are in use.
In addition to these tools, the system offers a complete range of filters and effects that can be applied independently to each tool. These include traditional filters like binarisation or averaging as well as other much more advanced ones, such as HDR and shading correction to enhance images from even the most complex targets.
Other functions designed to save time and money include automatic generation of user manuals, which include product screen shots, by clicking a single button – and user interfaces generated by simply selecting and modifying one of the many templates. 1D and 2D barcodes can be read within seconds using an auto tune button.
