    摘要:

    高通量植物三維表型的研究對(duì)判定植株表型特征至關(guān)重要,?;跈C(jī)器視覺的植株三維表型獲取方法在溫室中已廣泛應(yīng)用,能夠動(dòng)態(tài)監(jiān)測(cè)植株生長(zhǎng)過(guò)程,,但在大田復(fù)雜環(huán)境中應(yīng)用較少,。以大田生長(zhǎng)的玉米、大豆植株為研究對(duì)象,,基于機(jī)器視覺分析方法對(duì)不同生長(zhǎng)時(shí)期玉米,、大豆植株進(jìn)行個(gè)體和群體的三維重建,并基于手動(dòng)測(cè)量值對(duì)葉長(zhǎng),、葉最大寬進(jìn)行精度評(píng)估,。研究結(jié)果表明,葉長(zhǎng),、葉最大寬的計(jì)算值與手動(dòng)測(cè)量值的R2均大于0.97,,精度較高,表明大田環(huán)境下此方法可以滿足作物表型三維構(gòu)建參數(shù)提取的精度要求,,但是當(dāng)冠層遮擋較嚴(yán)重時(shí),,三維重建精度將明顯下降。進(jìn)一步自動(dòng)提取了株高,、冠幅和器官生長(zhǎng)動(dòng)態(tài),,結(jié)果可為與基因型相關(guān)的表型高通量分析提供方法,并可進(jìn)行株型與冠層輻射的精確評(píng)價(jià),。

    Abstract:

    High-throughput phenotyping of plant three-dimensional (3D) architecture is critical for determining plant phenotypic characteristics. The acquisition of 3D architecture of plant phenotypic traits based on machine vision has been widely applied in greenhouse research. Growth process of the plants can be dynamically monitored. However, the application of machine vision method in the field is less due to the complex environment. Machine vision method was used to obtain multi-view image sequences for field growth maize and soybean at different growth stages. Then 3D architecture of individual plants and its populations were reconstructed. The accuracy of calculated individual blade length and maximum width was evaluated according to the measured data. The results showed that there was a good agreement between measured and calculated blade length and blade maximum width with R2 which were both more than 0.97. Then the dynamic changes of plant height, crown surface and organ growth were extracted based on reconstructed 3D architecture automatically. The results can provide a method for high throughput phenotypic analysis related to genotypes and help to evaluate the plant architecture and canopy radiation.
