Three-dimensional ecological floating bed used for urban black and odorous riverway water quality improving and water purifying

The invention discloses a three-dimensional ecological floating bed used for urban black and odorous riverway water quality improving and water purifying. The ecological floating bed structurally comprises a floating bed structure body, biological stuffing and biolith. The structure forming method includes the step that the three-dimensional ecological floating bed is formed in a river or lake which flows slowly or is still through simple assembly. The ecological floating bed is mainly used for removing N and P nutritive salt in an urban black and odorous riverway and other organic pollution loads in water, improving the water transparency and increasing dissolved oxygen. The three-dimensional ecological floating bed has the advantages that the concept of the aquatic plant-biological stuffing microorganism-biolith combined ecological floating bed is provided for the first time by a water quality improving and water purifying method of the three-dimensional efficient ecological floating bed, and ecological floating bed plants, biological stuffing contact oxidation and biolith microorganisms have a successive relation for treating a water body and effectively complete functional complementation; particularly in winter or other kinds of low-temperature weather, the biological stuffing and the biolith can effectively compensate vacancy of the aquatic plants in a withered state to continuously and efficiently purify the urban black and odorous water body heavily polluted and recover and reconstruct water ecology and water functions.

Depth information extraction-based wall flatness detection method

The invention discloses a depth information extraction-based wall flatness detection method and belongs to the distance measurement technique based on binocular vision. According to the technical scheme of the invention, the depth information from a camera to a wall surface is extracted by a binocular camera. Two sets of image pairs of a to-be-detected region, namely two depth information graphs, are respectively acquired from different angles, and then the corresponding depth information is obtained. During the acquisition process of the depth information graphs, the existing Hhartley correction method is improved, and the real-time performance and the accuracy of the correction process are improved. Meanwhile, one depth information graph is rotated and translated, so that the coordinates of the imaging spaces of the two depth information graphs are overlapped. In this way, a reinforced depth information graph is generated. The mode of the depth value of the reinforced depth information graph is adopted as the distance value of the to-be-detected region. Based on the size relationship between the distance value and a preset threshold, the flatness of the to-be-detected region is judged. The method can be applied to the intelligent plastering operation and has the advantages of simple, convenient and intelligent operation, high flatness detection timeliness and high accuracy.

Data converter, data conversion method and program

A construction with an improved compression-function execution section is achieved. A data conversion process with use of a plurality of compression-function execution sections and through a plurality of process sequences in which divided data blocks constituting message data are processed in parallel is executed. Each of the plurality of compression-function execution sections performs a process with use of a message scheduling section which receives a corresponding divided data block of the message data to perform a message scheduling process, and a process with use of a chaining variable processing section which receives both of an output from the message scheduling section and an intermediate value as an output from a preceding processing section to generate output data whose number of bits is same as that of the intermediate value through compression of received data. The plurality of compression-function execution sections, respectively performing parallel processing commonly use one or both of the message scheduling section and the chaining variable processing section, and allow a single message scheduling section or a single chaining variable processing section to be utilized. Downsizing of a hardware configuration and simplification of processing steps are achieved by such a construction.
