An integrated automated remote digital image collection system

[摘要] Executive Summary:Low cost automated digital image collection systems can be integrated into any environmental monitoring station that uses data logger technology.A prototype imaging unit, made from 'off the shelf' components has been successfully deployed at an MLA funded study site in North Queensland, Australia.The primary role of the imaging system is to capture images of runoff events as data is logged and to collect a daily image of the study site, providing a record of how ground cover changes over time.It uses a 2 mega-pixel camera that is able to store around 500 images on a 256 MB Secure Digital media card.This equates to around 500 daily images or over 8 hours of photography at one minute intervals.The unit is housed in a weather proof enclosure and is largely self contained, relying on existing systems only for power and triggering.By integrating into existing infrastructure, the cost of the parts for the prototype system was around AU$400 (March 2004).The digital images that are collected can be correlated with associated datasets enhancing data analysis, interpretation and communication capabilities.This paper details the system comonents, construction and application.
