It also requires specialized software to view, making it less accessible to the full project team. This reality capture process yields precise and detailed results, but it requires specialized training to do successfully, and comes with a significant price tag. Historically, the construction industry has relied on laser scanning to capture the visual information needed to build 3D models. They are then run through a computer model, which plots ground features and contours. Photos are captured from the air using a drone, airplane, or helicopter.

Similar to photogrammetry, this approach uses a series of photographs to map site terrain for greenfield projects. While the imagery quality typically isnвЂ™t as good as photogrammetry, this method is preferable for accuracy, particularly in hard-to-reach, complex areas of a facility.

The data points are then positioned together to create a вЂpoint cloudвЂ™ and a navigable 360В° photo tour. This LIDAR-based method captures data by running laser scanners from several positions in a facility. Usually used by the surveying industry, they do this with laser technology but is not specifically laser scanning. LIDAR is the overall process of using light to measure the distance to a predetermined target. The software uses this information to align the pictures and assemble a virtual and navigable 3D model of the space. A technician takes multiple photos from different angles around a space and captures the objects in it, then a computer algorithm processes the images to find similar pixels in the photos. Depending on requirements, a team may employ one or more of these on a project. There are several methods for capturing data to produce a 3D model. What are the different reality capture tools?

It also gives clients the advantage of being able to вЂwalkвЂ™ through the new space at the concept phase, giving you the opportunity to make changes and understand the space before construction starts. This information allows us to identify potential problems and detect clashes, and to solve them before they happen. Designers then map the planned project details into the model, allowing everyone to visualize the outcome of a project before it begins.ДЇor example, project teams can see where pipes will enter walls, where equipment will sit, and how it connects to utilities. Regardless of what reality capture method you choose, the data collected is used to create a 3D digital format of the existing space, called a Building Information Model (BIM). These tools improve project efficiency while also giving clients a more detailed look at your future facilities. Construction project teams are increasingly adopting reality capture tools as part of their workstreams.
