Introduction

Objective

Develop a software solution for creating

accurate photo-realistic polygon models

from high density point clouds and digital

imagery.

Latest Specifications

Developed Components

• ZE Point Cloud Registration Module

• ZE Point Cloud Geo-referencing Module

• ZE Surface Modelling Module

• ZE Texture Mapping Module

Progress to Date

• Point Cloud Registration/Geo-referencing• Implemented adjustment module for point cloud

registration• Developed and tested ATR algorithm • GUI is undergoing development

Progress to Date• Surface Modelling

• Decreased run-time ten fold• Able to model more accurately

Texture Mapping Components I• Tie Point Acquisition & Camera solution

Texture Mapping Component II

Progress to Date• Synchronizing Frame Controls

with Viewport• Implementing Movement

of Camera• Finalizing Import File Format• Finalizing Efficient Display Method• Optimizing Frame Controls • Inverse Kinematics of Geographic Points

Resolved Risks

• Huge data set Long run-times• Require efficient data structures and data processing

techniques• Set appropriate thresholds and parameters in data

collection and processing

• Back up methods• Have a backup method for every module, if component

fails, attempt second method• Trade off between ease of implementation and quality of

output
