High-flux greenhouse plant phenotype measurement system based on multispectral point cloud fusion

Abstract

The invention discloses a high-flux greenhouse plant phenotype measurement system based on multispectral point cloud fusion. TOF cameras and multispectral cameras are arranged under multiple perspectives, three-dimensional point cloud and multispectral images under the multiple perspectives are gathered, registration is carried out between a multispectral image and a three-dimensional point cloudimage, unified transformation of multi-perspective coordinates is carried out, multi-perspective multispectral three-dimensional point cloud fusion is realized, high-flux greenhouse plant phenotype measurement based on the multispectral three-dimensional point cloud model is realized, measurement on the plant external phenotype (three-dimensional morphological information) and the internal phenotype (physiological information) is realized, and the high-flux greenhouse plant phenotype measurement system has the advantages of high precision, fast speed and strong applicability.

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 multispectral point cloud fusion. Background technique [0002] Plant phenotype is determined or influenced by genes and environmental factors, and reflects all physical, physiological, biochemical characteristics and traits of plant structure and composition, plant growth and development process and results. With the rapid development of functional genome, transcriptome and proteomic theory and technology in recent years, especially the rapid development of sequencing technology, some plant genes and whole genome sequences have been annotated, but due to the low efficiency of traditional plant phenotype measurement technology (Basically manual operation), small analysis scale (few samples and traits involved), large error (difficult to rule out interference from human an...

Problems solved by technology

With the rapid development of functional genome, transcriptome and proteomic theory and technology in recent years, especially the rapid development of sequencing technology, some plant genes and whole genome sequences have been annotated, but due to the low efficiency of traditional plant phenotype measurement technology (Basically manual operation), small analysis scale (few samples and trait categories involved), large error (difficult to rule out interference from human and environmental factors), weak applicability (difficult to refer to analysis methods and data across species), resulting in plant phenotypes The data can no longer meet the analysis of the relationship between genotype, environment and phenotype

The serious lag of plant phenotyping measurement technology has become a new bottleneck restricting the development of crop molecular breeding and plant functional genomics research
