Benefits of technology

This patent is about a system that calibrates video cameras using people as calibration markers. The system matches one or more individuals between cameras and identifies certain key points on the person's body. It then matches these key points and automatically re-calibrates the cameras. The system also extracts detections from each camera, synchronizes frames, and clusters people based on their key points. By finding matches between cameras and aligning the key points, the system reduces human intervention, cost and time. The technical effect of this patent is that it provides a reliable and efficient method for calibrating video cameras using people as markers.

Problems solved by technology

The system monitors accumulated errors over time.
If the accumulated error is large, re-calibration is needed.

Description

CROSS REFERENCE FOR RELATED APPLICATION[0001]The present application is a continuation patent application of (a) U.S. Non-Provisional patent application Ser. No. 17 / 028,388 entitled “SMART SELF CALIBRATING CAMERA SYSTEM”, filed on Sep. 22, 2020. Thus, this present application claims the benefit of U.S. application Ser. No. 17 / 028,388, filed Sep. 22, 2020, all of which are incorporated by reference herein.BACKGROUND OF THE APPLICATION[0002]This application relates to systems, methods, devices, and other techniques for video camera self-calibration based on video information received from more than one video cameras.[0003]Methods and apparatus for calibrating cameras in the certain areas are very common. Some methods are using reference objects and manual methods to calibrate the cameras. However, these methods need human intervention and cost time and money.[0004]Therefore, it is desirable to have systems and methods to enable self-calibration for the cameras to save time and efforts...
