Dynamic simulation of agronomic indicators and three-dimensional re-construction for fruiting bodies of Sparassis crispa
In order to establish a factory growth model for fruiting bodies of Sparassis crispa,reveal the formation pro-cess of the morphology and yield of fruiting bodies of S.crispa,realize three-dimensional visualization and automatic ex-traction of phenotypic parameters.Minxiu No.1 was used as experimental material,two factory cultivation experiments were carried out.The agronomic indexes of fruiting bodies of S.crispa were collected every 2 days,yield and multi-view image data were obtained at the maturity stage.Through SPSS software analysis,the model of the agricultural indicators such as the height,length,width,yield of fruiting bodies and mass of the whole S.crispa package with the growth days were established,the determination coefficients of the simulation model were between 0.935 and 0.995,the prediction ef-fects were good,the mean relative errors ranged from 2.39％to 8.09％.Then,the yield of fruiting bodies of S.crispa were evaluated non-destructively by using the fruiting bodies height,length and width as independent variables.Finally,based on multi-view picture of fruiting bodies of S.crispa,three-dimensional visualization and the automatic extraction of the height,length,width,surface area,volume of fruiting bodies were realized,compared with manual measurements or cal-culated value,the mean relative errors were less than 14％,which provides important support for high-throughput pheno-typic parameters obtained automatically and excellent new variety breeding of S.crispa.
