HACARUS Inc. (Headquarters: Nakagyo Ward, Kyoto City; CEO: Takashi Someta) will launch "HACARUS Field Vision Tuner," a cloud application that allows users to retrain the PPE detection AI for its accident prevention AI solution "HACARUS Field Vision" to match their on-site environments, starting July 1, 2026. "HACARUS Field Vision Tuner" is a cloud application that automatically extracts and trains learning images from videos uploaded by users. Users can optimize the PPE detection model to their specific site environments without needing specialized AI knowledge. The generated trained models can be downloaded and applied to the edge AI boxes within the "HACARUS Field Vision" system. This allows for updating AI models in response to environmental changes while maintaining a configuration that does not require an internet connection for on-site operations. UI Screen (Tagging Function) ■ Background of Development The accuracy of PPE detection in manufacturing environments is heavily influenced by site-specific conditions. Factors such as the shape, color, and wearing position of PPE, as well as camera angles, lighting conditions, and worker movements, vary from site to site. Consequently, a general-purpose AI model may not achieve sufficient detection accuracy. Previously, adapting to PPE not covered by standard functions or adjusting detection accuracy due to on-site environmental factors required retraining by HACARUS. This resulted in a certain lead time and cost for model adjustments whenever new PPE was introduced or the work environment changed. "HACARUS Field Vision Tuner" supports more rapid updates of AI models in response to environmental changes at each site by enabling users to perform the retraining process themselves on the cloud. ■ Key Features of "HACARUS Field Vision Tuner" Retraining Possible with Just Video Upload and Tagging By uploading videos filmed on-site and tagging the target PPE and conditions, the retraining process can proceed.
