The processing module receives image frames from the camera and depth data from the depth sensor. The processing module analyzes the depth data to identify which of the pixels are in a plane of a sufficiently large size to indicate that the identified pixels correspond to a playing surface of the athletic playing space. The processing module then determines that gravity is in a direction normal to the identified plane. By finding the direction of gravity within the images, the algorithm for calculating performance parameters based on the trajectory of a moving object within the athletic playing space can be greatly simplified, thereby decreasing the processing burdens associated with calculating the performance parameters and providing more accurate trajectory estimations with fewer measured trajectory points."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for monitoring objects in athletic playing spaces","description":"A system uses a camera, a depth sensor, and a processing module to track a moving object in an athletic playing space over time.
