Pretreatment device for seed testing, rice seed testing system and seed testing method

The invention relates to a seed testing pretreatment device, a rice seed testing system and a seed testing method, after whole ears are threshed, the number of residual empty grains on the residual ears is obtained by obtaining image information of the residual ears, and the total number of grains is obtained by combining scattered grains obtained by previous threshing treatment and the number of the residual empty grains obtained according to the image information after photographing. The total number of grains and the number of empty grains on the residual ears can be obtained without manual threshing, the seed testing efficiency is improved, and the working intensity of researchers in the seed testing process is reduced. 本发明涉及一种考种前处理装置、水稻考种系统和考种方法，在对整穗进行脱粒处理后，通过获取残穗的图像信息，进而得到残穗上残留空粒数量，结合先前脱粒处理所得的散粒和拍照后根据图像信息所得的残留空粒数量得到谷粒总数。无需通过人工脱粒来获取谷粒总数和残穗上部分空粒数量，提高考种效率，降低考种过程中研究人员的工作强度。
