Abstract:
On the basis of describing the idea of the virtual-real surveillance video compression method，this paper describes the technique process of the compression method，proposes the relative evaluation factors，and constructs the evaluation model. The experimental results have shown that，the impact from the time scale factor is conditioned by the appearance of the prospect of moving target. When there is no moving target，the compression rate of unit-time length is higher than the compression rate of cumulative-time length；when there are some moving targets，the compression rate of cumulative-time length is higher than the compression rate of unit-time length. The impact from the compression level factor is remarkable. Comparing to the compression rate of image projection fusion style，the compression rate of object projection style is less than 1%. Comparing to the compression rate of fore-ground independent and prospect projection styles，the compression rate of prospect abstraction projection style is less than 1%.
