[0002] Plant phenotype refers to all physical, physiological, biochemical characteristics and traits that reflect the structure and composition of plants, as well as the process and results of plant growth and development. Precise acquisition of plant phenotype information is an important basis for agricultural scientific research. By collecting images of plants from multiple angles and combining artificial intelligence algorithms, the three-dimensional structure reconstruction of plants and the extraction of phenotype information can be achieved.

[0003] Chinese Patent with Publication No. CN205014959U discloses a movable and liftable plant phenotype measurement device, which includes a plurality of imaging units arranged above the plant to be measured and a fixed bracket; the fixed bracket includes a chassis, a vertical beam installed on the chassis, a cross beam installed on the vertical beam, and a universal wheel installed at the bottom of the chassis; the imaging unit is installed on the cross beam; the cross beam is movably connected to the vertical beam and can move in the vertical direction. Its beneficial effects are as follows: 1. By adjusting the number of imaging units, plant samples with various throughputs can be measured, greatly improving the measurement throughput. 2. Through software control, phenotypic measurement of plants can be carried out regularly, for example, 10 - 20 times a day, which can more accurately record the changes in plant phenotypes; 3.
