Plant-phenotype-oriented mobile proximal sensing system and data acquisition method

Abstract

The invention discloses a plant-phenotype-oriented mobile proximal sensing system and data acquisition method. With a mobile vehicle as a data acquisition platform, the system herein at least includestwo two-dimensional laser radar units, a mounting frame, a depth imaging sensor, a control unit and a portable power source, wherein the mounting frame is fixed to a mobile platform, the two-dimensional laser radar units and the depth imaging sensor are mounted on the mounting frame, the portable power source powers both the two-dimensional laser radar units and the depth imaging sensor, the twotwo-dimensional laser radar units are mounted respectively on slants that are arranged at the two ends of the mounting frame and that have a fixed included angle relative to a vertical face, the two two-dimensional laser radar units acquires two-dimensional section data by alternate downward scanning, the depth imaging sensor is mounted at the center of the mounting frame, the laser radar units and the depth imaging sensor are connected with the control unit via cables and are controlled via the control unit. The data acquired herein can reflect more understructure information of plants, the performance is better, and the cost is lower.

Description

technical field [0001] The present invention relates to a plant phenotype-oriented lidar imaging technology, in particular to a plant phenotype-oriented laser scanning and depth imaging mobile proximity system and data acquisition method, which can acquire plant three-dimensional point clouds and red, green and blue (RGB) characteristic information. Background technique [0002] Plant phenotype is determined and influenced by genetic and environmental factors, and reflects all physical, physiological, biochemical characteristics and traits of plant structure and composition, plant growth and development process and results. Accurate realization of plant phenotyping is helpful for crop genotyping and breeding. Plant phenotyping has a strong demand for efficient and low-cost phenotype acquisition technologies. [0003] 3D lidar has broad application prospects in the quantitative measurement and inversion of plant parameters because it can quickly and accurately obtain 3D poi...
