디딤센서

디딤센서 (Deediim Sensor Co., Ltd.) is a Korean machine vision company that develops surface-inspection sensors combining optical systems, image acquisition and processing, and GPU-based computing. Its stated aim is to address limitations of conventional machine vision inspection with a sensor that handles defect inspection tasks previously considered impractical.

The company's lead product, Surf.Finder, departs from the conventional approach of interpreting image brightness distribution produced by illumination. Instead it quantitatively measures and analytically recognizes the optical material state of a surface in order to inspect surface condition. The company markets the underlying concepts as "Free-Illumination" and "Surface-Property-Imaging," and positions the approach as standardizing surface inspection with benefits such as cost saving, internal sharing of inspection technology, remote control, reduced personnel expense and productivity improvement.

Deediim is registered under the standard industry classification for manufacture of electronic application cutting machinery, with its main business listed as vision sensor manufacturing and software development and supply. Its team is described as composed of people with professional experience in the machine vision field.

Business model

The company manufactures and supplies vision sensors and develops accompanying software, selling inspection sensor hardware and software into industrial settings.
