Dear TI E2E support forum,
I've opened a support ticket (CS2747855) and was instructed to post on this support forum. I'll copy and past the ticket.
Our customer needs a Machine Vision system to guide a human operator in the process of placing components into an automated processing chamber. The chamber is equipped with a number of mechanical holders which can keep the components. When all the components are ready, the automated processing begins. The idea is:
- operator scans a component (e.g. with a barcode reader or the like)
- the system determine the correct mechanical holder wher the component should be placed
- a projector (I hope a TI's one) highlights the mechanical holder with, e.g. a green light surrounding it
- the operator places the component on the highlighed holder
- our machine vision system verifies correct placing and correct placed component
- if there is an error, the projector will highlights the error, e.g. with a red light
- repeat from point 1 until all components are loaded
We need to determine model and number of projectors to be used. We have little experience with projectors in general and were evaluating DLP® 3010 Light Control Evaluation Module DLP3010EVM-LC or DLP LightCrafter Display 3010EVM-G2 DLPDLCR3010EVM-G2 but we are open to other solutions.
The chamber and the mechanical holders are mainly made of stainless steel. The chamber will be illuminated by 3 Arteleta BR21.D with a mean illumination of about 1500 lux.
The mechanical holders are arranged in a 1700x1050 mm area, and the projector lens should be placed at a distance of about 550-650 mm. The throw ratio is about 0.337-0.34. We cannot increase the projector distance because of mechanical limits of the chamber (the projector should be placed inside the chamber). Note that only a small area of the entire projection area should be highlighted at a time (from 50x50 mm to 270x150 mm). Mechanical holders are grouped into zones inside the entire projection area, so we can also evaulate multiple projectors, one for each zone. The zones are arranged in this way (all measures are in mm and approximate) from the point of view of the projector:
This is a side view:
Zones 2, 3, and 4 have same dimensions. Please note that red lengths are the available space inside the chamber. If a single projector is not feasible, we can evaluate multiple projectors (I think one for zone 1, one for zone 5 and one for zones 2,3,4).
Please let me know which products are best suited for this kind of application and what evaluation board can we purchase to test.
