Abstract
Abstract A high-resolution vision system for a detailed inspection of parts. A charge coupled device provides high-resolution in both an X and a Y axis. Data from the charge coupled device resulting from a standard part is stored in compact form. Compact data from a part being inspected is compared with the compact data from the standard part to determine if the tested part is good or not.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
146 words
A high-resolution vision system for a detailed inspection of parts, said system comprising: a camera sensor for sequentially observing a plurality of individual parts, wherein said camera comprises; a charge coupled device; a clock synchronization circuit coupled to said charge coupled device; an analog to digital converter for converting an output of said charge coupled device into digital signals; and a transition detector and compaction circuit which compacts digital data from the digital signals by recording the changes in levels of said digital signals thus yielding compacted data; a storage means for recording compacted data which indicates the changes of levels in a digital signal of a standard part to which similar parts can be compared; and comparison means for individually comparing the compacted data of each of a plurality of similar parts to the compacted data of said standard part without expanding the compacted data.
Claim 2
Dependent Claim

A high-resolution vision system for a detailed inspection of parts, said system comprising: a camera sensor for sequentially observing a plurality of individual parts, wherein said camera comprises; a charge coupled device; a clock synchronization circuit coupled to said charge coupled device; an analog to digital converter for converting an output of said charge coupled device into digital signals; and a transition detector and compaction circuit which compacts digital data from the digital signals by recording the changes in levels of said digital signals thus yielding compacted data; a storage means for recording compacted data which indicates the changes of levels in a digital signal of a standard part to which similar parts can be compared; and comparison means for individually comparing the compacted data of each of a plurality of similar parts to the compacted data of said standard part without expanding the compacted data.
Claim 3
Dependent Claim
31 words
A vision system as defined in claim 1 including means for providing a visual resolution of 0.0025 inches of a part in both an X axis and in a Y axis.
Claim 4
Dependent Claim
47 words
A vision system as defined in claim 1 including a microprocessor controller, said controller operating at a sample rate which is a multiple of a part inspection rate to enable a multiple of image edges of each part to be inspected each time the part is inspected.
