Device and method for real-time online assessment of soil structure evolution based on unmanned vehicle

Abstract

The invention discloses a device and method for real-time online evaluation of soil structure evolution based on an unmanned vehicle. The device includes an unmanned vehicle, telescopic equipment, macro video image acquisition equipment, a first signal receiver, and a second signal receiver device, remote control computer; the present invention first establishes the macro-distance video gray-scale image database, then establishes the corresponding relationship between each substance and the gray-scale value interval in the database, and then counts the gray-scale image representing each substance in the macro-distance video gray-scale image According to the number of pixels in the value range, the relationship with its corresponding material content or form is established. 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 evaluates the micro-distance video of the field soil sample, and has high test accuracy; the micro-distance video image is used to more accurately identify the composition of the soil and its evolution; it can carry out large-scale long-term continuous real-time online monitoring of the soil in any area , so as to obtain the law of soil evolution in this area.

Description

technical field [0001] The invention relates to the field of soil evolution monitoring, in particular to a real-time on-line evaluation device and method for unmanned 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, but this method has low efficiency, low precision, and large manual errors. 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. Moreover, in many special scenes and areas (such as severe chemical pollution, high temperature, swamps, some slopes and other dangerous areas) it is n...

Problems solved by technology

[0004] However, when the existing video image acquisition equipment shoots macro video images, it is easily affected by natural conditions (such as rain and snow, smog, dust, sunlight intensity and electromagnetic interference, etc.), resulting in clear macro video images.
