Title Proper : Accurate and cost-effective natural resource data from super large scale aerial photography
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : Increasing amounts and types of timely and accurate data are required for monitoring toensure compliance with natural resource regulatory requirements. This study developeda cost-effective method to partially fulfill these data requirements using super largescale aerial photography (Scale: greater than 1:2,000). Two synchronized, metric,Rolleiflex 70mm (2.76in) cameras mounted 12m (40ft) apart on a rigid platform andcarried at 5.6 kmlhr (3 knots) by a helicopter collected this high resolution, 3D imageryfrom Alaska and Washington. The overlapping photo pairs provided 3D views ofnatural resource objects as fine as twigs. The 12m (40ft) inter-camera distanceimproved ground visibility between tree crowns of dense old growth forests. Analyticalstereoplotters and the application of photogrammetric principles enabled measurementand interpretation of photo objects such as trees and their height in a cost-effective way.Horizontal and vertical measurement accuracy....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
