A new unscented particle filter using Gaussian particle swarm optimization (GPSO-UPF) algorithm is proposed in this paper to improve particle degeneracy and particle impoverishment. It uses unscented particle filter in importance sampling process and incorporates Gaussian particle swarm optimization into re-sampling process. Through GPSO-UPF, the probability density moves closely to true state, the number of effective particles and efficiency are increased, the particle degeneracy is reduced and particle impoverishment is relieved. The experimental results show that the state estimation precision of GPSO-UPF is higher than estimation precision of PF and UPF.

The transformation between different coordinate systems is of great significance to modern engineering applications. Several common known points are needed before the transformation. However, it is difficult to obtain the coordinate information, especially the elevation information, of common known points in practical engineering applications. Aiming at this problem, four methods (four parameters method, polynomial-fitting method, height substitution circular method, transform-coordinate method) are compared and analyzed in transformation accuracy and other aspects. The data used is actual and has no elevation information. The results show that all the methods have high conversion accuracy. And the transform-coordinate method has the advantages of no zoning, only one iteration, only 3 common points, high precision and consistent accuracy index.

Although TCAR can realize three short baseline frequency to achieve fuzzy degree of single epoch algorithm, due to the influence of ionospheric delay and observation noise, long baseline three frequency ambiguity fast calculating is still a big difficulty of navigation and positioning. This paper presents a new method without geometric ionosphere three frequency ambiguity calculating. The method based on pseudorange observation with different weights, auxiliary lane wide and narrow lanes can eliminate the influence of ionosphere residual, make wide lane and narrow lanes to solve only affected by the observation noise, and then through the epoch more smooth get wide lane and narrow lanes fuzzy degree of value. Through the measured frequency BDS three long baseline data shows that compared with the classical TCAR algorithm, this method can greatly improve the solving accuracy of long baseline ambiguity, data smoothing and verification can achieve fast calculating of long baseline ambiguity.

In order to get the optimization combination of radial distortion, tangential distortion and non-square pixel correction, to improve the aerial measuring precision of image points, we studied the effect of different combination of distortion parameters on the measurement accuracy of image points. The aerial survey was conducted by three types of shots on the North Campus of Liaoning Technical University. Finally we use the Virtuozo AAT-PATB software to test the precision of survey results on several typical combinations. The results show that the distortion parameters comprehensively can greatly improve the accuracy of aerial survey results as far as possible, when conditions is well. When the condition is limited, the combination of K₁ and K₂ model can eliminate the influence of most lens distortion, and improve the accuracy of the results. The research results can provide reference for other UAV aerial missions.

A three-dimensional visualization scheme for large-scale oblique photography model based on quad-tree structure is proposed. Firstly, the triangular mesh model is simplified by using half-edge collapse of quadratic error measure (QEM), and then these hierarchical simplified models are textured and blocked, each block is named using Morton encoding rule. Finally, the scene is organized according to the pyramid structure of LOD (multi-level hierarchical structure).We evaluated our visualization plan for large-scale 3D models with oblique photogrammetry technology on a dataset of a city. Experiment results show that the method can dynamically load the appropriate models according to the pixel size on the screen. It is demonstrated that the schema is effective and useful for realtime visualization of large-scale 3D models with oblique photogrammetry technology.

Aiming at the existing problem of high mismatching rate and insufficient corresponding points for vehicle-borne sequential images,as a result of the plentiful repetitive texture in the building façade area,a new method combining auxiliary POS and the KLT corner tracking algorithm is proposed in this paper. In the first place, through taking full advantage of POS information, the local approximate stratification façade plane and DEM are established to get the initial displacement required by the KLT algorithm.Then a new strategy tracking the façade and road area separately is employed to ensure a good distribution of matching points.After that,the final result is obtained by integrating the RANSAC and epipolar constraint to eliminate the matching error. The implemented experiments show that the presented method could solve the preceding mismatching problem,as well as obtaining adequate and uniformly distributed corresponding points for a more robust aerial triangulation process.

Because of the lack of texture region is short of distinctive features or having serious repetitive features, the matching algorithm purely based on feature is very difficult to obtain the strong unique feature descriptors, which leads to greatly increasing of mismatching ratio. But the AKAZE algorithm based on the nonlinear scale space, which can better take into account the texture and detail information of image, so it has a certain application value for image matching in the lack of texture region. Calculating the cross-power spectrum between images by Fourier-Mellin phase correlation technique using the FFT and log-par conversion, can obtain the rotation, scale and translation parameters between the two images. So, this paper obtains the geometric relationship between the two images by Fourier-Mellin conversion, which is used for restraining the matching range of the feature points detected by the AKAZE algorithm, to solve the problem of image matching in lack of texture region. Experimental results show that this method can increase the number of matching points, and the matching accuracy.

Each pixel of strip image obtained by push-broom aerial photography system has precise coordinates of WGS-84. The stereo-model formed by aerial strip image is rigid, bearing strong stability, but has low precision in Z coordinate after carried on aerial triangulation adjustment. Because of influenced by model's rigidity and the low precision of model's Z coordinate, layout of model's image control points for aerial triangular adjustment is different from other situations and has its own particularity. When surveying the image control points is carried on under multi-spatial reference constraints without other choices, including CORS base station, GPS control network, level control network etc. in aerial photograph region. It is key point to validate the coordinate precision of the control points in existing spatial reference with IGS points and EGM2008 data to avoid the their potential errors and make certain the image control points can be surveyed quickly and precisely.

To address the problem that it is difficult to display the surveying and mapping history in museums due to its unconnectedness with museum studies, this paper proposes a new framework of the surveying and mapping history in ancient China. Based on the research on the history of surveying and mapping and museum exhibition principles, the framework is composed of four parts: sprouting, foundation, prosperous development, falling and transformation. Each part is weaved with several questions through which the surveying and mapping history is summarized. The framework keeps a balance between serious history and interesting exhibition. From the exhibition planning of the Zhejiang Surveying, Mapping and Geoinformation Science Museum, the proposed framework can not only guarantee a scientific and integrated exhibition, but also help the public know surveying and mapping. This paper excavates the surveying and mapping history in the context of making museum exhibitions and interprets the surveying and mapping history in ancient China from a new perspective.
