Two-step calibration reconstruction algorithm is proposed based on binding basic elements and the calibration objects. This method first according to basic elements of building recovery its 3D coordinates of six (or more) points in a single image, then through the 2D and 3D coordinates of these points obtain camera projective matrix, whole building is reconstructed finally. White-Clothing Pavilion...
Propose a data reduction algorithm of height direction slice so that the scattered point cloud data of large group of ancient buildings can achieve a higher reduction ratio on the basis of maintaining the shape feature. And apply it to reconstruct the Small Wild Goose Pagoda with point cloud techniques, achieving good modeling results.
This thesis puts forward the concentration of CO real-time monitoring design based on the MSP430F247 MCU. The system is composed of electrochemical CO sensor, the center processor MSP430F247, LCD monitor and GSM module, which can realize the collection of CO concentration in the air and real-time temperature in the space, the high-speed precision of the data analysis, keyboard sets alarm threshold,...
Through the discussion of the structure and the design process about micro-programmed control unit (MCU) in CPU soft-core. An optimized design method of next-address shift logic in MCU is presented in this paper by designing instruction operating code and arranging microinstructions storage. Some of codes using Verilog HDL are given. Simulation result indicate that this method is practical and has...
