5results about How to "Real-time filtering" patented technology

This utility model relates to the field of metal surface treatment and discloses an anodizing tank with a protective structure, including a tank body. A mounting bracket is fixedly connected to the inner wall of the top of the tank body, and a base plate is fixedly connected to the inner wall of the bottom of the tank body. Support feet are fixedly connected to the four corners of the lower surface of the base plate. A protective component is provided at the left end of the tank body, and a sealing component is provided inside the tank body. The protective component includes a suction pump, which is located on the left surface of the tank body, and a connecting pipe is fixedly connected through and to the left surface of the tank body. In this utility model, under the action of the protective component, real-time filtration and impurity removal of the electrolyte can be achieved. The filter plate can effectively intercept impurities such as metal debris. Combined with the suction pump and the inclined base plate, electrolyte circulation is promoted, reducing the impact of impurities on the oxide film. Furthermore, the positioning component facilitates quick assembly and disassembly of the filter plate, avoiding frequent shutdowns and improving production efficiency.

This disclosure relates to the field of image processing technology, and provides an image deduplication method and apparatus for equipment security inspection. The method includes: acquiring a group of images to be deduplicated, the group comprising multiple pairs of images to be deduplicated; extracting spatial feature vectors for each pair of images in the group of images to be deduplicated based on a preset Siamese network model; calculating a similarity value between the spatial feature vectors of each pair of images in the group of images to be deduplicated; extracting color data feature vectors of images in each pair of images to be deduplicated based on the similarity value and a preset image threshold; and determining whether duplicate image pairs exist in the group of images to be deduplicated based on the color data feature vectors. This disclosure can quickly and in real-time find and filter out duplicate images taken at the same angle in the same scene, saving time and effort, increasing work efficiency, and improving the efficiency of subsequent equipment security inspection.

The utility model belongs to gear box detection technical field, especially electric outboard motor gear box experiment table, in view of the problem that the existing gear box test bench lacks intuitive oil detection function and lubricating oil lacks circulating filtration system, present the following scheme, including test bed, test bed includes work bench, bearing plate and four support legs, and work bench and bearing plate fixed connection in four support legs's top and bottom respectively, filter oil tank, color developing box and two oil pump all fixedly connected in bearing plate's top, filter oil tank includes oil storage tank, filter core casing and filter screen, filter screen is detachably inserted in the inboard side of filter core casing, and filter core casing is inserted in the one side of oil storage tank and is fixed through bolt, in the utility model, filter oil tank and color developing box etc. Component is integrated, constructs closed loop oil circuit system, realizes the real -time filtration and state monitoring of lubricating oil in the testing process, thereby the scientificity and reliability of testing process are improved significantly.

The utility model relates to the technical field of drinking utensils, in particular to a filtering type folding water bag which comprises a water bag body, a lifting handle is arranged on the water bag body, a water outlet end is arranged at the lower end of the lifting handle, a screw cap is in butt joint outside the water outlet end in a matched mode, a faucet valve is arranged on the screw cap, and a butt joint end is arranged on the inner side of the screw cap. According to the water bag, the filter element pipe extending into the water bag body is inserted into the inner side of the screw cap, real-time filtering in the water source flowing process is achieved, water filtering equipment does not need to be additionally carried, and the water bag is convenient to use. The problem that a traditional water bag can only store water and cannot purify water is solved, the safety of outdoor drinking water is improved, the design that the filter element pipe is connected with the butt joint end of the inner side of the screw cap in an inserted mode is adopted, a plurality of components do not need to be disassembled when the filter element is replaced, the filter element can be replaced in an inserted and pulled mode only by unscrewing the screw cap, and maintenance operation in the outdoor environment is simplified.

The application discloses an unmanned ship autonomous berthing navigation system and method based on infrared vision tight coupling. The system comprises an infrared vision sensing module, a vision processing module and a multi-sensor fusion pose estimation module. The application installs an active infrared light source array at a berth and uses an improved deep learning target detection network at the end of the unmanned ship to detect the light source array. Secondly, through the constructed tight coupling integrated navigation system based on factor graph optimization, the information fusion of heterogeneous and asynchronous multi-sensors is realized in a sliding window. The method can detect the infrared light source array, ensure the realization of robust visual feature extraction under complex light changes, fuse the information of heterogeneous and asynchronous multi-sensors, realize the distance and attitude estimation of the unmanned ship relative to the light source array of the berth, overcome the vulnerability of a single sensor, provide accurate self-state and relative berth attitude information for the autonomous berthing of the unmanned ship, and improve the long-term navigation consistency.
