Three-dimensional scanning method, three-dimensional scanning system and three-dimensional scanning device used for plant organ form

Abstract

The invention discloses a three-dimensional scanning method for a plant organ form, which is used for establishing a three-dimensional model for the surface of a plant organ. The method specifically comprises the following steps of: (1) acquiring a calibration board image and a plant organ image sequence; (2) processing the calibration board image to acquire a calibration parameter and a radial aberrance coefficient of image acquisition equipment; (3) extracting the outline of the plant organ in each image of the image sequence of the whole body of the plant organ; and acquiring all pixel point coordinates on each outline; and (4) processing each outline and acquiring the point set characterizing a measured object, namely a plant organ shell so as to realize the three-dimensional reconstruction of the plant organ. The method is mainly used in the field of agriculture and forestry; a plurality of scanning points can be obtained at the same time; the scanning speed is high; the scanningprecision is high and reaches a pixel level; the automation of the main operation is basically realized; and the method is simple and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a three-dimensional information scanning and restoring method of plant organ morphology. Background technique [0002] Plant organ morphology refers to certain organs of plants such as roots, branches, stems, etc. of plants. The shape and distribution of plant organs in the medium or space, that is, the difference in the shape and configuration of plant organs, has a significant impact on important physiological functions such as nutrient absorption and phosphorus source distribution. , breeding, interplanting and increasing agricultural production have an important guiding role. In addition, plant growth modeling and simulation based on agriculture and forestry not only provides accurate measurement data for analyzing plant ecophysiology, but also provides intuitive and reliable experimental materials and materials for computer simulation experiments and cr...
