Abstract

The invention discloses a high-flux greenhouse plant phenotype measurement system based on Kinect autonomous calibration. A manner of combining a Kinect camera and a precision rotary platform is adopted to realize multi-view-angle RGBD image acquisition; a multi-view-angle three-dimensional point cloud uniform coordinate system is realized through a Kinect camera by adopting an autonomous calibration manner; a foundation is laid for accurate reconstruction of a three-dimensional point cloud model of plants, and the integrated level and the automation level of an existing measurement system areextremely improved. In an imaging system, a two-axis sliding rail and a laser distance measuring sensor are combined to realize accurate control on postures of the imaging system, so that the imagingsystem can be used for phenotype measurement of the plants in a full growth period. By adopting the measurement system disclosed by the invention, efficient, accurate and reliable detection problemsof greenhouse plant phenotypes are solved; the measurement efficiency, precision and applicability of the greenhouse plant phenotypes are improved, so that the system has important meaning on promotion of information-based, digital, accurate and intelligent management of installation horticulture of China.

Description

technical field [0001] The invention relates to the field of high-throughput greenhouse plant phenotype measurement, in particular to a high-throughput greenhouse plant phenotype measurement system based on Kinect self-calibration. Background technique [0002] With the development of my country's facility agriculture, my country has become the largest producer of facility horticulture in the world. Since plant information is an important basis for intelligent management of facility greenhouse cultivation, efficient, accurate and reliable measurement of plant information is an important aspect of facility greenhouse intelligent equipment. One of the key issues that need to be solved urgently. Traditional plant information measurement is mainly obtained by manual measurement and visual inspection, which has defects such as slow speed, high intensity, strong subjectivity, and large errors. It has been unable to meet the needs of intelligent equipment for facility greenhouses, a...
