Problems solved by technology

[0007] In recent years, a large number of improved algorithms based on mixed Gaussian background modeling have emerged. The advantages of these methods are that they have better detection effects and can remove motion interference in complex background situations; the disadvantages are that they have a large amount of calculation and storage, and the running speed is slow, so they are not suitable for Resource-constrained video-aware nodes

Abstract

The invention discloses a video sensing node-oriented target detection method. The video sensing node-oriented target detection method includes steps of compressed sensing, background modeling, updating and post-processing, different sampling values M are set according to interest regions, the sampling rate is improved at the 1.2 times region of the previous frame of a target block, and the sampling rate is lowered at the background region; when the background brightness change is small, the Gaussian distribution number for modeling is lowered to lower the learning speed rate; when the brightness change is large, the Gaussian distribution number is improved to improve the learning speed rate.

Description

technical field [0001] The invention relates to the technical field of target detection, in particular to a target detection method for video perception nodes. Background technique [0002] The wireless video sensor network is an "intelligent" autonomous measurement and control wireless network system composed of a large number of video nodes with communication and computing capabilities arranged in a specific way or randomly in the monitoring area. The video sensor nodes have a strong collaborative ability, and complete the global task through local image data collection, processing and data interaction between nodes. Compared with the traditional monitoring mode, the use of wireless video sensor networks to build a distributed intelligent monitoring system has the advantages of unattended, wide coverage, stable performance, high flexibility, and any combination of monitoring scenarios, especially suitable for traffic intersections, airports, etc. Target tracking and event...
