Research findings
Filter-difference study
Against the 84-record Intelligent Sensing Machine Vision Keyword Candidate Study, this 79-record cohort shares 63 records. Only 16 occur here and 21 only in the reference; the union contains 100. These are filter-membership differences, not company entries or exits.
| Company cohort | Directly linked pages | Share of public archive | Archive date |
|---|---|---|---|
| 79 | 79 | 0.4% | 2026-10-16 |
An ID-deduplicated archive snapshot, not the whole market, current recognition or operating results.
Filter differences and comparison link
The largest recorded sub-industry participation gap is for Sensors and sensing components: 0/79 here versus 4/84 in the reference, an absolute difference of 4.8 percentage points. The cohorts have overlapping company IDs and are not independent samples.
| sub-industry | Focal count/base | Reference count/base | Participation gap (pp) |
|---|---|---|---|
| Sensors and sensing components | 0/79 | 4/84 | -4.8 |
| Industrial internet and IoT | 2/79 | 6/84 | -4.6 |
| Instrumentation and testing equipment | 19/79 | 18/84 | +2.6 |
| Automotive structural parts and components | 3/79 | 1/84 | +2.6 |
| Automotive night-vision ADAS vision systems | 2/79 | 0/84 | +2.5 |
Zero means no recorded label, not no business; multi-label cells overlap.

Recorded roles and delivery checks
Inspection systems must connect to process assessment
The Machine-vision inspection systems label covers 12 records (15.2% of this cohort). This archive clue raises a verification question about Inspection assessment or diagnosis for a defined process; it does not establish that these companies already deliver it.
