VALIDATING A VISION SYSTEM

Published on : 2017-05-12 18:05:23

Hardware – This includes validating camera resolutions, lens distortion, shadows cast by lighting and the surrounding environment. On the largest scale we used standard image acquisition techniques. Machine vision has a long history in part inspection, ensuring consistent and predictable quality. This is expensive, time consuming and does not allow for flexibility when the part type or size changes validating a vision system. Presenting parts to robots varies widely from application to application. When an application requires information in 3 dimensions (X, Y and Z) also with rotation, 3D vision should be used. At the highest resolution an area of about 10-by-8 µm is shown. As vision technology advances and is augmented with other sensing technology the ability to deploy robots into a wider range of applications increasing. Call 440-498-8465 or click on the button below to speak with an industrial automation expert at RAF Automation about gauge R&R guidance and support. Flexible feeding is ideal for production processes requiring multiple part types or a family of parts. The lens provides focus and how large an area the camera sees. Inspired by the famous short film Powers of Ten of Charles and Ray Eames released in 1977, we visualise the defects on a 10-by-10 mm metal plate on different scales. Learn how our robotic vision systems can be applied in your operations today. Performing a gauge R&R identifies how the system you choose influences your results. Parts are fed out of a bulk hopper and onto a feed surface. Using a single camera mounted to the robot, this powerful vision system is ideal for precise part location required for assembly, racking, dispensing, machine loading, product sorting and welding applications validating a vision system. We continue to work with more complex and difficult applications, like bin picking, that have a higher degree of part variability. 3D CAD matching provides simplified, accurate part registration, allowing even complicated parts to be identified. The system is programmed using Cognex EasyBuilder programming software.

  Vision technology has become a critical component for many robot applications, enabling robots to be deployed into new areas.  Learn More MotoSight 3D CortexVision simplifies the use of 3D vision in robotic guidance applications. Cameras can also be fixed mounted above the workspace. The ruler has sharp, defined edges and is linear, which is easy to measure. Yaskawa Motoman has partnered with the industry leaders in vision technology. We zoom in and crossfade to images aquired by an electron microscope (at about 0:10-0:12). Data Recording Methods Consider measurement systems that allow for the collection of data in its “raw” state. The purpose of running a gauge R&R (R&R = repeatability and reproducibility) is to identify inconsistent measurement techniques and tools, as well as identify the effects of different operators. While giving robots eyes doesn’t make them self-aware, it does enable them to perform simple operations in ways that dramatically improve their performance. Vision systems can be used in conjunction with a variety of other perception tools. Software– This means validating the software and available “soft tools” used to calculate the measurements, and then picking the one best-suited for the application. This might be over a particular work area, over a moving conveyor belt, or over a flexible feed surface. Typically, the “resolution” of a camera is not the same as the “precision” of the system. Our MotoSight products can be applied to error proofing in virtually any application. The point-and-click software environment and self-learning technology dramatically reduce setup time. Example: Imagine you are trying to measure two items as different as an egg and a ruler. Error proofing is similar to Presence/Absence. For example, robots guided by vision can locate parts to be picked up, determine where to apply a weld, inspect parts that have been assembled, determine where to place a part. However, if you’re trying to assess the egg, the odd shape makes it difficult to measure.

MotoSight 2D with MotoPick is designed for robot guidance in high-speed packaging, cartoning and case packing applications. In this example the camera moves with the robot. Types of Systems Typical vision systems consist of structured lighting, a camera with lens, a processor (sometimes embedded in the camera) and vision software.free no credit card sex site with chat.
. Our MotoSight products can help locate the parts so that the robot can then pick them up precisely and consistently. Flexible feeding is an innovative way to present parts to a robot. This includes parts that are loosely fixtured, parts that are presented on a conveyor and in some cases parts in a box or bin. MotoSight 3D BinPick is an easy-to-use hardware/software solution that utilizes a Canon 3D machine vision system to quickly and easily recognize and pick parts that are randomly placed in bins. Additional sensing can provide a depth and feel dimension to traditional vision capabilities. The majority of vision applications can be solved with our MotoSight 2D product.   Using conveyor tracking, each robot picks the product and performs the necessary operation. The camera captures the image and sends it to the processor. Robotic Vision Uses Giving robots eyes enables them to perform increasing complex operations in ways that dramatically improve their performance. Video Hardware / Software Products Most vision systems return information in 2 dimensions (X and Y) with rotation. Other processes simply require parts to be identified for a specific operation such as assembly or kitting. The type of lens and its focal length along with lighting methods significantly impact precision. This can provide much better resolution (a closer look) of the part, but it also means the robot can t do other things while a picture is being taken. All of the above are examples of robot systems using a vision system to perceive and respond to the environment around the robot. In the process vision has become accepted and embraced by many companies who see the value it brings to their operations; value in the form of improved product quality, more manufacturing flexibility and higher throughput. .
