The invention provides an ignition combustion engine by the mode of mixing hydrogen and oxygen with high-octane fuel and a control method thereof, and particularly relates to a fuel storage and supply system of the ignition combustion engine by the mode of mixing the hydrogen and the oxygen with the fuel, fuel proportional distribution and combustion process control, wherein, a set of on-board hydrogen and oxygen production, a storage and supply device is added to the system on the basis of retaining main parts and an electronic control unit of the original engine. The hydrogen and oxygen mixed fuel electronic control unit (12) can control the opening and closing of a hydrogen nozzle and an oxygen nozzle according to sensor signals c-h so that the engine can run in three combustion modes such as pure hydrogen and oxygen mixed gas, hydrogen-oxygen-high-octane fuel mixed gas and pure high-octane fuel according to different operating conditions, thus greatly lowering HC and CO emission in the case of cold starting and idling of the high-octane fuel combustion engine and improving the thermal efficiency and emission level of the high-octane fuel combustion engine in middle and low load stages.

The invention discloses a closed roof capping method for upward filling mining. The characteristic of this method is that after mining the last stratification, use a drilling rig to drill four exhaust holes at the four corners of the roof, and then build partition walls around the goaf to level off the bottom of the goaf and the roof. The partition walls around the goaf, the bottom of the goaf and the roof are pasted with waterproof materials to enclose the goaf into a closed filling space, and the filling material is injected into the closed filling space through the filling patio. When the filling material overflows, the exhaust When filling holes, stop injecting, and after the filling material fills the closed filling space, cover the four vent holes and the filling patio with a layer of waterproof material, and seal them with cement. The invention prevents the discharge of water in the filling slurry, maintains the volume and shape of the filling slurry, and forms a completely top-connected filling body after the filling material condenses, thus solving the problem of filling and top connection. The process of the invention is simple, safe, reliable, easy to implement and low in cost.

The invention relates to an image rendering method by utilizing a depth image. The image rendering method is characterized by comprising the following steps of (1) inputting a color image and the corresponding depth image, (2) inputting rendering parameters of a new viewpoint, (3) rendering the new viewpoint by utilizing the color image and the depth image to obtain a color image I, (4) performing post treatment on the color image I to obtain an image II and (5) outputting the obtained image II. According to the image rendering method, the process of image rendering and the process of hole filling are combined, and therefore the problem of hole filling is directly solved in the process of image rendering. In this way, the method not only can lower the time complexity of an algorithm but also can improve the quality of image rendering.
