Abstract: Calibration of various sensors may be difficult without specialized software to process intrinsic and extrinsic information about the sensors. Certain types of input files, such as image files, may also lack certain information, like depth information, to effectively translate regions of interest between images taken from a different perspective. Landmarks can be used to establish points for associating regions of interest between images taken from a different perspective and provided as an overlay to verify sensor calibration.

Abstract: An adjustable physical structure for producing hydraulic formations for whitewater recreationalists includes a control structure, and an adjustable lip located downstream of the control structure. The control structure can include a crest and a ramp. The crest constricts and/or elevates (dams) the flow water to increase it's energy and focus the flow of water. Downstream of the crest, the ramp routes the flow of the water to the adjustable lip. The ramp can have varying and non-linear slopes and plan configurations. Additionally, the ramp can be static or adjustable to elevate the flow of water and vary the velocity and energy of the supercritical flow as it is passed to the adjustable lip. An adjustable invert physical structure comprises a shaped structure configured for placement on the invert of the channel. The adjustable invert physical structure can be moved or adjusted in horizontal and/or vertical directions to shape the flow of water.

Abstract: A water diversion system includes a hydraulic chute and a chute screen assembly in the hydraulic chute having a wedge wire screen. The water diversion system also includes at least one collection chamber located below the screen configured to collect filtered diversion water which has passed through the screen. The hydraulic chute includes a base, a crest, a sloped accelerator, and an abrupt drop with an adjustable lip, which forms a hydraulic formation in a downstream pool. The hydraulic chute can also include sloped sidewalls, which constrict the flow of water and form fish passage zones. In addition, the chute screen assembly can include a modular panel configured to facilitate construction, maintenance and replacement of the wedge wire screen.
