The
Intelligent Automation Systems 4DI Imager is a non-contact
gauging system that creates a three-dimensional wire frame
model of an object under inspection. The system shines a
series of laser-generated lines on an object and measures
the line locations using three CCD cameras. The 4DI Imager
board detects the laser line locations in the images and
outputs a series of points. A PC-resident application package
displays a wire frame image and performs image analysis
functions. |

System Overview
Bolton Engineering prototyped the design and created simulation
test vectors by writing a set of ‘C’ programs.
The Programmable Logic Device (PLD) was written in a high-level
design language and fully verified against the vectors prior
to board construction. Bolton Engineering wrote low-level
routines to test the hardware. These routines were incorporated
into the client’s application software for final test.
- ~480 million multiply-accumulate operations per second.
- Three separate differential-input 9-bit accurate video
channels with individual offset and gain.
- Flexible video front-end and video timing generator
supports a wide variety of externally or internally sync’d
cameras.
- All computational, formatting and timing logic contained
in a single 100K gate PLD; front-end reconfiguration logic
and interface to PCI controller contained in two other
PLDs.
- Supports any combination of pixel interpolate or frame
grab on any three cameras simultaneously.
- Designed to meet PCI V2.1, FCC part 15 class B, EN 55022
class B, IEC 1000-4-2, -3, -4.

Results
- Electronics met or exceeded all design goals, and came
in at half the client’s budgeted cost.
Project Scope
Bolton Engineering was responsible for writing the specification,
creating schematics, designing PLDs, laying out the circuit
board layout, writing test software, design verification
and testing, creating test plan, and writing documentation. |
