Relations Between Pseudoinverse Adjustment and Weighted Parameter Adjustment of Free Network;

This paper chooses close -range target stereo image data as main topic of3DCM,and carries through comprehensive and systemic study on photogrammetry of free network bundle adjustment from theory to practice.

Freenet is an adaptive peer-to-peer network application that permits the publication,replication,and retrieval of data while protecting the anonymity of both authors and readers.

Thus it discusses the essence and the social effect of the network freedom as well as the spirit of time from a broader cultural angle.

The contradiction between network freedom and network regulation is the basic value conflict of network culture,which affects the contradictions in network cultural value,such as the contradiction between the unary and the multivariate,between democracy and centralism,between individual and society,and so on.

Improving the accuracy of free net adjustment for subgrade monitoring on the basis of data analysis;

The GPS free net adjustment model with the systematic errors compensated has been researched based on the influence analyses of systematic errors in GPS observations.

Based on the fundamental theory of the free net,through the lead of the robust estimation onto the free net adjustment, the free net robust adustment is constitued, and the adjustment calculation formula is obtained by using generalized converse mathematics tool.
