This invention describes a robot designed to navigate using a camera. When bright light, like sunlight, causes the robot to mistake it for obstacles, the system filters this out. It does this by continuously taking pictures, calculating the average brightness from a series of recent images, and using this average to set a dynamic threshold to ignore overly bright areas in real-time.
Why it matters: The 2021 filing predates significant advancements in lightweight AI models for real-time image processing on edge devices. Modern deep learning could offer more robust glare filtering than a simple mean intensity threshold.
AI gives you a few directions you could take this. Pick one, and we check whether your version is different enough to patent, then write the filing.
