Who developed the first "standalone" Smart Camera that contained a DSP or Microprocessor for decision making?
By "smart" let's say that we're describing a machine vision device that has the acquisition, possibly optics and illumination, and processing components and software along with suitable industrial I/O to communicate results, all packaged in a single integrated component. One also might have to limit it to devices that were commercially "viable": a few components and custom devices like this were around in the late 1980's or before but were either not marketed or did not achieve broad success. To my knowledge, no manufacturer or person claims to have had the world's first "smart camera". However, Dickerson Vision Technologies introduced a component that I worked with which indeed met all of the definitions above as early as 1990/91 called the DVT smart camera. Likely there's something earlier. (Allen-Bradley had the VIM much earlier but that was a tethered "smart" camera system.) It would be interesting to hear other comments on this.
I am brand new to this site. I have a need for some type of vision that can identify the edges of textiles (mostly all white) such as sheets, towels, Wash Clothes, etc. I would envision two types of robotic arms that would be able to fine (grab) the two ends on a side, not opposite ends, and spread them out. I understand that the vison may now be able to identify white textile. Any help or a company that may have the vison to do this would be greatly appreciated. Thanks Jeff Nichols
Hi Jeff; Machine vision technology is regularly applied to many inspection, guidance, and measurement applications. The thing to keep in mind is that the components that are used are just the tools with which one builds and programs a successful application like yours. That said, the design and implementation of a solution that involves many components is usually handled by an integration partner skilled in that task. While your specific project sounds like one that hasn't been widely installed already, it certainly appears on the surface to be feasible. I suggest that you engage a good integration partner to help you in the specification and if appropriate integration of your system. Since my company does perform those services you can feel free to contact me directly for more information. Also, you will find other similar and excellent integration companies on this AIA website. Many are "AIA Certified", a designation indicating a high level of integration expertise.
I am working on a report on applications of machine vision. I came across terms like "Voxels over Raster Grid" and "Point Clouds", when I was reading about improvements in Machine Vision functions. I am a mechanical engineer and I want to have some basic idea what these terms mean in respect to machine vision. Also how are Embedded Vision and Computer Vision different from Machine Vision.
Hi. I'm curious about the sources you've found relative to your question about Voxels and pixel Point Clouds related to machine vision function improvement. I have not yet seen voxels specifically used in machine vision, but perhaps someone somewhere is moving in that direction. Overall both are just related to the "representations" of 3D spacial scenes or objects and not necessarily related to the functionality of machine vision tools that would process, segment, and locate or measure objects in 3D space. Further, Voxels or "Volume Elements" as opposed to Pixels or "Picture Elements" are a representation more commonly used in things like gaming, movie making, and medical imaging. I think you will find several good webcasts on the topic of 3D machine vision in general here at visiononline.org that might help you in your research. Due to space, I'll leave the other question for another time.
We are a manufacturer that prints on continuous web whether it be opaque but mostly clear. The prints can consist of hundreds of designs and unlimited ink colors since we are a custom made to order company. These production runs could last for short period of time ~10min or anywhere to multiple hours. From my experience with vision and the challenges we produce we are trying to find a print inspection solution where the software could easily learn the print with minimal operator involvement and inspect the material for print defects such as print voids. Some challenges to know is that we do not having any registration marks on our product so it is a continuous web print could be within 54-62" wide. If anyone has any solutions or ideas please let me know, thanks in advance!
Hello Hark; The print inspection application you outline has potential for success, but it would be premature to speculate on the exact details of the required technologies until more information is gathered.. In pursuing this type of solution with machine vision technology, it is critical to fully analyze the requirements, scope, and metrics of the application in preparing a project specification. You will find many useful articles and educational materials here on the Vision Online website, and if you need assistance in the design, specification and integration of your project, you will also find AIA Certified System Integration partners on this website who serve your geographic area.
