Predicting object height using distance data and models
The patent US12038267B2 describes a sophisticated system designed to optimize the settings of an imaging device by utilizing a combination of distance sensing and illumination technologies. The system includes an illumination device to light an object and a distance sensing device that measures the distance to the object within its field of view. Central to the operation are one or more processors that receive distance data at two different times as the object moves through the sensing area. These processors access a distance measurement model to predict the object's physical parameters and estimate its future distance when it enters the imaging device's field of view. Based on this estimated distance, the system can adjust the focus of the imaging device's lens before the object is captured, ensuring optimal image quality.
Additionally, the system is capable of making brightness adjustments for the illumination device based on the estimated distance, which may include setting exposure times or adjusting brightness levels. The processors can also incorporate motion parameters, such as the object's velocity and acceleration, to refine the distance predictions further. The method outlined in the patent allows for timely image capture and adjustments, enhancing the overall imaging process. This innovative approach aims to improve the efficiency and effectiveness of imaging devices in various applications, from photography to surveillance.
