Abstract: A system for identifying ponding water located on a field from image data is described. In an approach, an image of an agricultural field is analyzed using a classifier that has been trained based on the spectral bands of labeled image pixels to identify a probability for each pixel within the image that the pixel corresponds to water. A flow simulation is performed to determine regions of the field that are likely to pool water after rainfall based on precipitation data, elevation data, and soil property data of the field. A graph of vertices representing the pixels and edges representing connections between neighboring pixels is generated. The probability of each pixel within the graph being ponding water is set based on the probability pixel being water, the likelihood that water will pool in the area represented by the pixel, the probability of neighboring pixels being ponding water, and a cropland mask that identifies which pixels correspond to cropland.

Abstract: A portable CAVE automatic virtual environment system. The system uses a light weight collapsible frame with an overhead beam that is raised and lowered via a lockable hinge on each of the vertical supports. Ultra-short throw projectors are attached to the overhead beam at its lowest position and are raised to their functional position where they are automatically configured to aim at one of the included screens. The projectors display imagery on the screens that form a space around the user. The system auto-calibrates to align the projected imagery to the screens to form a seamless display across all screens. The invention significantly decreases the time and labor to set up and calibrate a CAVE system and collapses into folded parts for easy transport and storage.
