嵌入式技术在水稻花粉图像自动采集中的应用
Application of embedded technique in automatic collection of rice pollen image
摘要
Abstract
Wide application of transgenic technology in agriculture brings enormous benefit to the humanity, yet po-ses potential threats to the environment and ecological diversity. The safety concern of transgenic rice has taking the center stage in both public and scientific forum. Being regarded as a main way of gene flow,the rice pollen has be-come an important test subject for monitoring and evaluating of transgenic rice safety. It's of significance to establish the rice pollen diffusion model and calculate the isolation distance for rice gene safety. However, the traditional method of monitoring and collecting rice pollen needs heavy workload and can not provide actual data of rice pollen's space-time distribution, which is just required by the security evaluation model. We develop a portable in-strument for automatic collection of rice pollen image, which can obtain the rice pollen's space-time distribution without disturbing the natural subsidence of rice pollens. Based on the embedded Linux platform with ARM chip as its core component, the instrument adds external equipments such as camera, SD memory card and stepping motor to satisfy the function of the experiment. The instrument collects the pollen data as manual gathering as possible with least disturbance, and provides real-time spatial distribution of rice pollen. Results of application show that the data collected can meet the requirements of safety evaluation, which will enrich the database of rice pollen diffusion mod-el. The instrument saves human resources, and offers help for transgenic rice security monitoring and evaluating.关键词
