Object tracking using behavior and speed models
The patent US12043270B2 outlines a method and apparatus for tracking an object by utilizing two behavioral models: a free behavior model and a constant speed model. The method involves obtaining likelihoods for both models based on the object's position, speed, and type at two time points: a previous time point (t-1) and a current time point (t). The process includes predicting the object's position under both models and calculating the likelihoods based on these predictions. Additionally, the method incorporates a sensing mechanism using multiple detectors to enhance the accuracy of the detected position, speed, and type of the object, which are then used to determine a virtual position, speed, and type.
The apparatus described in the patent includes a filter that generates the likelihoods for the two models and a type corrector that adjusts the object's type based on these likelihoods. The type corrector employs a series of comparisons against predetermined threshold values to classify the object as either a first type (e.g., pedestrian) or a second type (e.g., two-wheeled vehicle). The system is designed to handle various scenarios, including cases where the object's type is unknown, ensuring robust tracking capabilities. Furthermore, the patent also covers a computer-readable medium that stores a program to execute the described tracking method, emphasizing the integration of advanced detection and classification techniques in object tracking systems.
