Abstract: The present invention discloses a method and an apparatus for extracting mountain landscape buildings based on high-resolution remote sensing images. The method comprises: segmenting a remote sensing image, and extracting non-vegetation areas from the remote sensing image by using NDVI; segmenting the non-vegetation areas, and extracting building areas by using NDBI; segmenting the building areas again, and calculating a normalized difference build shadow index NSBI of each patch; calculating NSBI separator of each patch in the non-vegetation areas and setting a separator threshold, and extracting landscape building areas based on the threshold. In the present invention, by introducing a near infrared band in the remote sensing image spectrum, in which there is a significant difference between shadows and non-shadows, the influence of large shadow areas in mountainous shady areas in the remote sensing image on the result of extraction is reduced.

Abstract: A urinal and a urinal flushing control method. The urinal includes a urinal body, an electromagnetic valve for turning on and off flushing, a capacitive sensor for sensing a liquid amount on an outer wall of the urinal body, and a controller for receiving a capacitance value signal to control on and off of the electromagnetic valve. The controller sets a flushing timing reference point when determining that a capacitance value exhibits a dropping trend after a first period since the electromagnetic valve is controlled to be turned off, and controls to turn on the electromagnetic valve when the flushing timing reference point is present for a second period. The above solution can reduce the chance of erroneous flushing and facilitate the adaptability respect to the glazed surface of the urinal body.

Abstract: A water pre-storable toilet includes a drain valve located between an injection duct and a water tank, and a float connected to the drain valve is further provided in the water tank. The float is configured to apply an upward pulling force to the drain valve at least when a water level of the water tank reaches a maximum. The float is also configured in such a way that when the float applies the upward pulling force to the drain valve, a buoyancy of the float may not overcome a water pressure caused by the water in the water tank to the drain valve, a weight of the drain valve itself, and a negative pressure formed when the pre-stored water in the injection duct reaches the highest water level regardless of water level of a water in the water tank and thus can't open the drain valve.
