Camera-Based Parking Spot Detection for Classified Lot Types

The patent introduces image processing technology as an intermediary between the vehicle and the environment. Instead of relying directly on GPS signals which may be unavailable, the system uses cameras to capture images of surrounding infrastructure (buildings, signs, trees) and processes these images to extract environmental information. This intermediary approach provides reliable environmental context independent of GPS availability.

The patent replaces the mechanical/GPS-based positioning system with an optical/image-based system. Rather than depending on satellite signals and geographic coordinates, the system uses cameras to capture visual data and processes these images to determine environmental characteristics and vehicle location, substituting one detection mechanism with another that is more reliable in certain conditions.

The patent implements dynamic adaptability where the vehicle operation system automatically adjusts its behavior based on the detected parking lot type. The system uses image processing to identify environmental features (buildings, signs, trees) and dynamically modifies parking operations accordingly, such as adjusting scanning patterns for vertical vs. horizontal parking or modifying detection algorithms for different lot configurations, rather than requiring pre-programmed static rules for each lot type.

The patent segments the complex task of handling multiple parking lot types into distinct processing stages: image capture, feature extraction (identifying buildings, signs, trees), parking lot type classification, and operation adjustment. This segmentation allows the system to manage complexity by breaking down the overall function into manageable modules that can be independently developed and tested.
