6 Off-the-shelf Embedded Solutions Look before reinventing the wheel Point Inspection Solutions Distributed processing 2D Vision Sensors Error proofing and ID 2D Smart Cameras General inspection 3D Line Profile Sensors Measurements Multi-point Inspection Solutions Centralized processing PC based Vision System User configurable system Hybrid Vision System Supplier-configurable system

7 Distributed versus Centralized Processing Which is better? Distributed Easy to setup and maintain. Predictable performance. No programming interface simplifies product validation. Easy to integrate into factory environments. System costs and spare parts are low for small system configurations. Consumes minimal space on the machine and retrofits are easy to integrate. Built for industrial use. Can be deployed in harsh environmental conditions without enclosures. IoT ready. Centralized Low cost for multi camera configurations. Flexible system architecture easy to expand and reconfigure to meet changing needs. High performance. Leverages computing advances in PC technology and optimized low-level software primitives. Greater storage capacity supports local saving of images. PC resources make it very easy to communicate information across networks. PC systems are generally windows based and open to support 3 rd party programs. This can provide additional cost benefits and access control.

16 Vision Systems (User Configured) 5 reasons to select PC based Vision Systems 1. Camera flexibility Configure system to match application exactly. Easy to expand. Cost effective. 2. Performance Leverage latest PC technologies to tackle demanding application tasks such as rendering and inspection of 3D scanned images 3. Usability Familiar look and feel. Easier to customize user interface for runtime. Possible to combine software applications (i.e. vision + motion). 4. Memory/Storage Greater capacity and efficiency for program execution. Lots of storage for image history. 5. No other option Some applications are just not possible or practical with any other solution

17 Vision Systems (Supplier Configured) Smarter than a PC system? Supplier locked systems Offer camera flexibility within the supplier product family Support supplier s software model Closed to 3 rd party tools and development Single source for support Performance May or may not leverage latest PC technologies May support smart cameras to offer a hybrid processing model inspections performed on the cameras, control & communication performed on the system processor Usability Based on supplier software interfaces Includes operator and control customization Not visible as a windows machine

18 Consider your Software Requirements Carefully Not all software is created equal Design Environment Communications Runtime Application development interfaces vary widely, from graphical point and click to traditional programming If you are new to vision, focus on ease of use. Great progress is being made to abstract vision complexity If you have different needs, pick a software package that you can migrate across vision system platforms Vision systems often need to communicate with 3 rd party equipment, such as PLCs or robots Make sure the vision software supports standard factory protocols that interface the equipment you specify Recognize that vision suppliers are not experts in using your 3 rd party devices Most applications require an HMI for monitoring results, changing programs and changing tolerance settings Some vision software will provide boilerplate runtime interfaces that are good for typical applications If you need something unique, pick a software package that allows you to develop a custom operator interface

19 Don t forget about Integration Factors to consider when deciding on a vision solution Challenge Operating Environment Robust Inspection Factory Communication Runtime Requirements System Expansion Ownership Cost Questions to Consider Does the system needs to be protected to operate reliably in your environment? Are you specifying the correct lighting, optics and sensor resolution for the application? What do you need the system to communicate and how? Are the factory protocols you need supported? How do you want to interact with the system at runtime? Do you require a custom operator interface? Do you need to restrict access or log user transactions? Will the system capabilities meet your changing needs over time? Does it offer enough flexibility to expand? Who will program and maintain the system? Can you support changes to the system internally?

20 Summary Thank you for your time Embedded vision is in use everywhere we look. Embedded technologies and solutions are widely available for industry development and/or deployment. Consider the pros and cons of making versus buying an off-the-shelf solution Vision sensors and smart cameras offer distributed processing, where each node performs an inspection. Vision sensors and smart cameras are generally easier to setup, integrate and maintain. Vision systems offer centralized processing, where multiple cameras combine to perform an inspection. PC based systems are familiar, offer higher performance and more flexibility. Supplier locked systems offer similar, but less flexible, capabilities. Select the product that best suits the application and user requirements. What is the task and who is going to implement and maintain the solution? Software is REALLY important. Try before you buy!
