Abstract: Systems and methods for detecting gestures of a swimmer in an aquatic environment such as a flume pool. In one embodiment, a pool system includes a set of cameras, one of which is an overhead camera positioned above the water in the pool to capture images of a swimmer. The system also includes computer processors, such as a GPU, CPU, and game engine which implement a computer vision platform. The processors are configured to receive images from the cameras, determine the swimmer's body position from the images, detect a defined gesture in the swimmer's body position, and in response to detecting the defined gesture, invoking a corresponding control operation of the flume pool, such as controlling water flow through the pool or updating an interface display which is projected onto the interior surfaces of the pool.

Abstract: Systems and methods for providing a distortion-free pool-surface display beneath a swimmer. In one embodiment, projectors are positioned below a water level at opposite walls of a pool, and are configured to project images to a display surface at the bottom of the pool beneath a swimmer. A camera is used to view images projected by the projectors and to provide corresponding image data to an image correction platform on a graphics processing unit (GPU). The image correction platform identifies distortions in the images, generates image corrections that counter the identified distortions, and applies the corrections to subsequently projected images. The image correction platform also generates image adjustment that cause overlapping portions of the projected images to match seamlessly. The projected images may provide immersive experiences, coaching/training interfaces or other interactive displays.
