And existing quality inspection system in defects detection and positioning application there are mainly two types of mode.First way is pure people
Working medium procuratorial organ formula, i.e., the photo visually observed dependent on industry specialists in production environment provide judgement.The second way is machine
The artificial quality inspection mode of auxiliary, mainly by having the filtering of the quality inspection system of certain judgement not have defective photo, by industry
Expert is detected judgement to the photo of doubtful existing defects.Wherein, the second way is mostly expert system and Feature Engineering system
System develops, and experience is solidificated in quality inspection system by expert, has certain automatic capability.
However, for the first quality inspection mode, due in existing industrial production line quality inspection system, the detection of defect picture and
Positioning relies primarily on the detecting system of pure hand inspection or feature based engineering.In the case of artificial quality inspection, need business special
Family carries out walkaround inspection in production scene, and manual record gets off to do subsequent processing again after finding defect.This method is not only imitated
Rate is low, erroneous judgement of easily failing to judge, and data are difficult to carry out secondary use excavation, and industrial production environment is often relatively more severe, to people
The health and safety of member can adversely affect.
For second of quality inspection mode, in the quality inspection system based on traditional expert system or Feature Engineering, feature and sentence
Set pattern is then all based on experience and is cured in machine, it is difficult to the development iteration of business, lead to the development with production technology,
The accuracy of detection of system is lower and lower or even is reduced to complete unusable state.In addition, the feature of traditional quality inspection system all by
Within hardware, when upgrading, not only needs to carry out key technological transformation to production line, but also expensive third-party vendor's curing in advance.
All there is apparent deficiencies in safety, standardization, scalability etc. for traditional quality inspection system, are unfavorable for traditional industry production
The optimization and upgrading of line.
