Sunspots

Sunspots sunspots.io (offline) estimates indoor sunlight exposure by analyzing window-view photos combined with device sensor data. Semantic segmentation and depth estimation is run on the photos. Location- and date-specific sun paths are calculated and projected using device orientation from the gyroscope.

Tech Stack

• Flutter
• Python, Flask OpenAPI
• GPS and Gyroscope access and normalization in Swift/Kotlin (iOS/Android)
• GCP hosting and observability infrastructure
• Semantic segmentation, depth estimation via pretrained models
