In this paper, according to the principle of Hough transform, using the multi - directional image information of an object to calculate the pixel points of the object in the space, and get the real three-dimensional image from the object surface texture mapping which is composed of pixel points. This method is good for the reconstruction of plant root, branches and flowers. There's a certain novelty value in this approach, such as the simple algorithm, simple operation, good robustness, and can be implemented on the PC to achieve the level of full automation and real-time processing, so it has important application prospect.

Agricultural expert experience highlights its advantages in the agricultural biological disaster forecast evaluation. Aiming at solving the expert experience fusion, this paper converted expert information into reliability probability density distribution, determined the evidence theory knowledge framework and basic probability distribution function based on the consistency definition and at the same time, the weight of each distribution is confirmed by using D-S synthesis rules. This paper ultimately obtained after-experience reliability level of fusion expert experiences in the agricultural production.

In mobile learning concept. In the first part, the reconstruction of the digital learning resources classification model is established, and then the the cloud based education platform "teacher student subject knowledge ontology" three-dimensional space application model based on. Finally, it designs the subject knowledge ontology resource information model, fully embodies the learning resources evolution, distribution and openness, to achieve basic education learning resources of convergent evolution and semantic polymerization, small granularity reuse and sharing, provides a good protection,
摘要：
The knowledge discovery mode of collaborative project management is built on the analysis of post Agent's work mechanism and the self-organizing neural network SOM. The goal is to built knowledge discovery model synchronized with the project process or the knowledge discovery mode of collaborative project management through the project information timely and intelligent acquisition and establish the project management information mechanism. Cooperation is the essential element of any project management activities. In the project management activity, Who was involved, how to participate, and how is the participation play a decisive role in the success or failure of project management. Cooperation is the essence of collaboration between different posts, it is meaningless to talk about collaborative project management mode without post.

To understand and master the alien biological disaster knowledge is the basis for right control of alien biology. Ontology is the tool for knowledge sharing and integration. Aiming at alien biological disaster knowledge, the construction thought of alien biological disaster knowledge ontology is analyzed in this paper, and a kind of highly structured organization of domain ontology construction method of MSOBCO and MSOBCO development method has been put forward and alien biological disaster knowledge ontology integration has been analyzed.
摘要：
The traditional diagnostic methods such as plant nutrition DRIS, M-DRIS, DOP, have different advantages. there will be a different result during diagnosis, causing difficult for users to make decisions. Evidence theory is a very effective method of uncertainty theory, which is one of fusion technology. Because evidence synthesis formula is based on different expertise knowledge, so that it provides a good way for the user to make decisions. Based on the preponderance of evidence theory, fusion model of nutrition diagnosis has been constructed in this paper. What is more, fusion treatment is used to the three diagnostic methods DRIS, MDRIS, DOP, and the results indicate that the model is feasible.
