摘要：水稻考种过程中对水稻种粒的计数、计量通常采用人工进行，不仅工作量大，而且长时间的测量会导致效率及精准度降低。而市面常用的数粒仪功能单一，只能完成水稻种粒数目统计，导致设备长时间闲置不用。针对上述问题，我们设计了基于图像处理和蓝牙传输技术的水稻种粒计数计量系统。该系统采用智能手机获取水稻种粒图像，并利用基于Android系统的APP进行图像处理，实现水稻种粒数的提取；利用与电子天平连接的蓝牙模块将水稻种粒质量无缝传输至智能终端，获取水稻种粒的质量信息；采用二维码技术识别水稻种粒样本，实现各样本的信息统计。

Abstract The method of manual counting and measurement of rice seed grains has been widely used in rice seed investigation. The low-efficiency and low-accuracy artificial measuring method is gradually replaced by automatic counting of granulators. However， the granulators commonly used in the market can only count the number of rice grains and then the equipments will be in idle for a long time. A rice seed counting system is introduced to solve the above problems based on image processing and Bluetooth transmission technology. The image of rice seeds is acquired using intelligent phones and a specialty software based on Android is developed to accomplish the statistics of rice seeds by image processing technology. The Bluetooth module linked with an electronic scale is also used to realize the wireless transmission of the weight of rice seeds to the intelligent terminal. Finally the QR code technology is used to identify the rice seed samples to accomplish the information statistics of the samples.

水稻是我国第一大粮食作物，也是单产水平最高的粮食作物，常年种植面积不足粮食作物的30%，产量却占粮食总产量的40%以上；我国有60%以上人口以稻米为主食，尤其是以粳米为主食的城乡居民日益增多[1]。发展水稻生产，对解决我国粮食供给安全具有举足轻重的作用。

考种是水稻品种选育的主要环节之一，可为育种家的决选提供重要依据[2]。我国有上千家农业科研单位需要每年长时间重复开展水稻种粒计数、计量及穗部性状检测等繁重的统计工作。目前，水稻种粒计数、计量一般采用三种方式：人工测量、光电式数粒仪及基于图像处理的数粒仪[3，4]。……
