Features

1 High accuracy and fast adaptability to satisfy on-site logistics demands
Our solution utilizes world-leading NEC image recognition technology so that no barcodes or product IDs are necessary for inspection. Objects can be recognized even if they are partially concealed, sticking out, reflecting light, slanted or bent in the image. Moreover, wide-ranging products — such as food, beverages, pharmaceutical products, pamphlets and manuals — can be inspected by the same unit.
NEC's state-of-the-art matching process enables fast inspection in a matter of seconds. So operational flow is not disrupted and operators have less stress.

2 Identification of item quantitie by weight
A camera and weight scale in the inspection line shoot and weigh the product, respectively. The photo and weight are then compared with pre-registered product data. High-speed, high-accuracy image recognition technology, in combination with weight data, enables instant confirmation of the number of items. Conventional checking by experienced operators is no longer necessary.

3 Support for visual inspection of products that cannot be automatically recognized
Products that lack sufficient details for automatic image recognition can be visually inspected by operators with assistance from displayed images of the articles that clearly indicate checkpoints
based on registered product master data. This feature contributes to more accurate and efficient visual inspection.
