Functions and Targets

Inspection Target	Software Advantage	Inspection Accuracy
Foreign Particles	Effectively differentiate against bubbles, false positive not affected by bubbles	Miss < 0.01% Fasle Positive < 0.5%
Floating Particles	Effectively filter out the noisy background caused by liquid surface waves and shadows, particularly sensitive to plastic particles	Miss < 0.01% False Positive < 0.5% (<30ml) < 2% (up to 500ml)
Heavy Particles at Bottom	Not affected by particle colour and reflectiveness of the particle, not affected by container bottom pattern	Miss < 0.01% Fasle Positive < 0.3%
Transparent Fibres	Specialty light field detection, very sensitive to fibres, not affected by scratches on container wall	Miss < 0.01% Fasle Positive < 0.2%
Glass	Target in-liquid particle and at-bottom glass separately; not affected by reflection and refraction of glass container	Miss < 0.01% False Positive < 0.5% (<30ml) < 1% (up to 500ml)
Lyophilized block	Holistic all-surface inspection for all abnormal conditions; very sensitive to any surface foreign particles	Miss < 0.01% Fasle Positive < 0.2%
Particles Stuck on Container Wall	Target stuck particles of above solution and below solution levels separately; understand the particle condition with super-resolution	Miss < 0.01% Fasle Positive < 0.2%
Container Cosmetic	Based on pattern recognition and multi-model algorithm, detect cosmetic defects of various kinds	Miss < 0.01% Fasle Positive < 0.2%
Finishing	Not affected by lighting and position variation, reliably detect all finishing abnormalies (capping, sealing, closure etc)	Miss < 0.01% Fasle Positive < 0.2%
Stopper	Effectively detect hard-to-observe missing or damaged stopper	Miss < 0.01% Fasle Positive < 0.2%
Fill Level	Completely computer vision based, reliably detect variance of > 1%, no need for extra weighing module	Miss < 0.01% Fasle Positive < 0.1%

Performance Features

Paired with various inspection modules, it can be directly installed at the key nodes of quality control (QA, QC) of the production line, plug and play. Different hardware modules can deliver various inspection functions. Users can choose one or more inspection modules according to their own needs. The entire module can be easily installed on the production line and takes up a small space. Users can select several modules to replace the existing manual inspection workload. Alternatively, they can install one module of certain inspection functionality at some point of production with high quality control complaint. Based on the collected inspection data, users can diagnose and identify the main cause and root problem for the weak link for the whole production line. They can then target this specific problem and improve the overall quality in short time.

This software can be installed on a fully automatic inspection machine. According to the inspection requirements by the user, the inspection machine can be configured with selected stations to optimize the inspection workflow. The fully automatic inspection machine equipped with Deep Inspect software has the best inspection performance in industry. The integrated inspection solution conducts holistic inspection just prior to the packaging step, achieving fast, efficient and accurate quality control.

Update the inspection accuracy of existing equipment: at present, a large number of automatic inspection machines have poor detection results: many missed detections coupled with high false positive rates. We can replace the existing inspection software with Deep Inspect to achieve significant improvement on the detection rate and largely reduce false alarms. Users can maximizing the utility of their current machines by retaining the mechanical and control systems, while benefiting from a much higher inspection performance with our cutting-edge software, killing two birds with one stone.
