    Abstract: With the rapid development of economy and society, human beings have put forward higher requirements for the living environment. Environmental conditions are closely related to human psychological activities,have a direct impact on human physical and mental health and economic benefits by intervening in human physical and mental health and economic benefits. Environmental psychology is committed to studying the relationship between environment and human system, exploring the law between people’s thinking, behavior and emotion and environmental materials in different social cultures and environments, and reveals the relationship between human activities and their surrounding environment, so as to seek a sustainable model of mutual adaptation to human and the environment. In order to explore the development of environmental psychology This paper puts to use CNKI database as the research object, uses CiteSpace bibliometry to objectively analyze the relevant literature of environmental psychology, and discusses the research status, research popular projects and development trend of environmental psychology. The results show that: 1) environmental psychology will continue to develop in the direction of people-oriented and steadily embark on the road of humanization, emotional value and spiritual experience; 2) the relevant theories and methods of environmental psychology will be applied to landscape design to optimize environmental quality and promote the coordinated development between people and environment; 3) environmental psychology examines people’s psychological quality and psychological problems under different social environment conditions, which can provide a reference value for improving ideological education and maintaining mental health.

    Abstract: Dental hard tissue registration is very challenging due to the complexity of histological structure, the variability of imaging modality and image quality. To benefit from the advantages of the relative works, we proposed a novel dental hard tissue auto-registration method based on multi-modality dental images. It employed the modified ICP algorithm and was especially effective for dental fluorescence imaging and the reflectance imaging. The algorithm firstly pre-processed the dental images to decrease the impact of imbalance local illumination. Secondly, we investigated a robust feature points extraction strategy, i. e. to calculate the boundaries of hard tissue as initial feature point sets, and to further extract the lesion areas based on the prior knowledge of oral histopathology for the refinement of feature points. Finally, our method executed the modified ICP algorithm on the basis of the special designed point-pairs rejection method and the improved registration strategy. The experimental results show that the proposed method is not only robust, but also can converge more quickly and achieve higher accuracy.
