Description

基于视频的农产品溯源方法及系统 Traceability of agricultural products based method and system for video

技术领域 FIELD

[0001] 本发明涉及农产品溯源技术领域,具体地说,是一种基于视频的农产品溯源方法及系统。 [0001] The present invention relates to the field of agricultural technology tracing, in particular, a method and system for agricultural production was based video.

背景技术 Background technique

[0002] 在农业生产的应用中,对于生产过程的记录已经成为很多厂家证明自身品质的一种方式。 [0002] Application of agricultural production in the production process for many manufacturers recording has become a way to prove their quality. 通过记录下农产品生产的每个环节,生产商可以实现问题追溯和责任到人的管理方式。 By record every aspect of agricultural production, manufacturers can achieve traceability and liability issues to people management. 目前对生产过程的记录大都采用文字记录或者拍照记录的方式。 At present most of the production process records by way of written records or photographs record. 这种记录方式的缺点是:一方面文字和拍照记录的方式不可靠,有作假的可能性;另一方面这两种记录的方式不够全面,一些可能有用的信息会被漏掉。 The disadvantage of this approach is the record: on the one hand and the camera records the way the text is not reliable, there is the possibility of fraud; on the other hand the way these two records is not comprehensive enough, a number of potentially useful information will be missed.

[0003] 另外,现有的基于软件信息录入、或是RFID等射频标签卡扫描标记录入的农产品溯源数据信息已经经过了人工的“二次加工”,并不能直接、可信地展示出农作物整个生长过程的种植操作流程,而空气温湿度等传感器网络感知的农产品溯源数据则均为环境参数的参数化量化,并不能直观的展示出农作物整个生长过程中的环境状况。 [0003] Further, the conventional software-based agricultural traceability data information entry, or other radio-frequency tag RFID tag scan card entry has elapsed artificial "secondary processing", not directly, credibly demonstrate entire crop planting operational flow growth process, the air temperature and humidity sensors and other network-aware agricultural traceability data of the environmental parameters are quantized parameters, environmental conditions and does not exhibit an intuitive crops throughout the growth process.
