Abstract

The invention discloses a real-time on-line evaluation device and method for vehicle-mounted macro-distance video images of soil structure evolution. distance from the video grayscale image database, and then, establish the corresponding relationship between each substance and the grayscale value interval in the database, then, count the number of pixels in the grayscale value interval representing each substance in the macro video grayscale image, and establish Finally, the actual characteristic parameters of the soil to be detected are determined according to the above relationship, and then the development state of the soil is determined. The present invention directly performs micro-distance video evaluation of on-site soil samples, and has high test accuracy; and the micro-distance video image is used to more accurately identify soil components and their evolution. After a large-scale long-term continuous real-time online monitoring of the soil in a certain area, the evolution law of the soil in this area can be obtained.

Description

technical field [0001] The invention belongs to the technical field of soil evolution monitoring, and in particular relates to a real-time on-line evaluation device and method for vehicle-mounted macro video images of soil structure evolution. Background technique [0002] At present, the monitoring of soil microstructure evolution mainly adopts the field test method mainly based on manual measurement, which has low efficiency, low precision and large manual error. Because this method needs to transport the soil sample from the field back to the laboratory for testing; on the one hand, after the soil sample is taken out from the ground, the stress acting on it will change; on the other hand, the soil sample During transportation, the properties of the soil will change; these reasons will lead to inaccurate final test results. [0003] With the rapid development of information technology, image processing technology has provided an unprecedented technical means for the devel...
