Imagery Processing Technology In Slope Protection Vegetation Root System Monitor Applied Research

Planting protect slope is a scale implicated lope reinforcement technology in recent years. It is theory of contains water consolidation soil using the vegetation the principle stable side slope,the control slope face corrodes,the preventing and controlling soil erosion,the use plant root system reinforcement soil body,simultaneously gets up the protection ecological environment effect.The vegetation solid slope method widely is applied in recent years in the side slope government,causes it's concurrently side slope forestation and the reinforcement function.But this kind of traditional method was still unable to solve plant's slope protection mechanism,vegetation solid slope positive effect questions and so on precise appraisal.This thesis is applies the digital image processing technology in a solid slope vegetation root system monitor attempt.Was peeps the type image method in the earlier period utilization array distribution to gain in the solid slope vegetation growth process rhizosphere physics factor in and so on root shape pictorial information foundations,to the solid slope vegetation root system pictorial information which gained carries on a series of correlation processing, such as,according to methods and so on image pretreatment,grey system theory carries on multi-level processing to the image,the division root system and the soil composition pellet, and withdraws the root separately long,the root diameter equal root shape parameter value,is finally realizes from the vegetation rhizosphere microphysics environment embarks the exploration vegetation solid slope mechanism to provide certain data support.This thesis has conducted the systematic research in the image pretreatment,image aspects edge examination and edge examination post-processing and so on.In the link of image pretreatment,this article has analyzed the image intensification some traditional method,and selects the method that most suits this system;In the link of the edge examination,the main utilization withdraws the slope protection vegetation root system edge outline based on the grey system theory gray connection algorithm,and carries on the comparison with the traditional edge examination operator,the result showed the gray connection algorithm surpasses other operators in the root system image edge detection and in noise antijamming ability,the experiment indicates this method's feasibility in the slope protection vegetation root system image edge examination;in the link of edge examination post-processing,the main utilization carries on the refinement,the filtration noise based on mathematics morphology method to the image,eliminates the short burr,the fill hole and the pit,connects the break point and so on,strengthened the image viewability and the accuracy;Plans provides the higher quality root system image through the above each step processing,is advantageous for later period to the root configuration parameter computation.
