Visualization application for interior progress monitoring in 3D environment

In the interior construction of building projects, a significant amount of schedule delay is caused by an inability of realistic appreciation the complicated interior work. Using computer visualization techniques, such as 4D or Augmented Reality (AR) model and color and pattern coding, users may compare the as-planned with the asbuilt interior construction progress. These technologies therefore play an increasing role in automatically analyzing the progress of complicated interior construction works, visualizing its progress condition, and making appropriate and quick corrective decisions. This paper introduces a visualization application that enables the user to monitor interior construction progress efficiently using construction photographs superimposed over a 3D model. This prototype of application represents as-built interior construction photographs, user's viewing point information, and the status of construction progress. This application allows the user to walk-through the 3D environment so that the user has an intuitive understand of the interior construction progress represented with colors and patterns.
