Device and method for quickly pre-judging soil type with panorama girdle photograph process

Abstract

The invention discloses a device and a method for quickly pre-judging soil type with a panorama girdle photograph process. A brace is perpendicularly fixed on a base; one end hole of each of two cross beams is fixed on the brace; a connecting rod of a girdle camera passes through the other end hole of each of the two cross beams; the lower end is provided with the panorama girdle camera and a miniature laser range finder probe; the probe is connected with a main body of a laser range finder; the main body of the laser range finder and a transmission system are respectively arranged on an upper cross beam; a gear in the transmission system and a side rack of the connecting rod of the girdle camera are meshed in a central hole of the base to move; and the camera is connected with a computer. The device is moved above a soil cave of the soil to be detected, a stepping motor vertically moves the camera down to the soil cave at a position to be detected; and at each time of moving up by 5cm, the computer controls the camera for photograph. A linear method is utilized for unfolding a panorama girdle image as a rectangle image, and the similarity between the unfolded image and the standard soil type section image is measured with the relevance of image texture features, so as to quickly pre-judge soil type.

Description

technical field [0001] The invention relates to a soil type device and method, in particular to a device and method for quickly predicting soil type by using a panoramic ring photography method. Background technique [0002] Soil refers to the loose layer of the earth's land surface that can produce plant harvests. It is the base of agricultural production and an important part of the natural geographical environment of the earth's surface system. Due to differences in soil-forming factors, different types of soil are distributed on the land surface. Correct soil classification and mapping are the basis for understanding soil, and are also the basis for land evaluation, land use planning, and promotion of agricultural technology according to local conditions. [0003] Conventional field soil type prediction methods are usually to comprehensively judge by excavating soil profiles, comparing and observing its properties and geological background conditions. Under field workin...
