digital engineering techniques Flashcards
What is a total station?
An electronic transit theodolite integrated with electronic distance measurement (EDM) to measure both vertically and horizontal angles and the slope distance from the instrument to the point, and an on-board computer to collect data and perform triangulation.
Total stations are essential tools in surveying for precision measurements.
What is photogrammetry?
Involves taking overlapping photographs of an object, structure or space and converting them into 2D or 3D models.
It is used by surveyors, architects, engineers, and contractors to create photographic maps.
What are the key uses of photogrammetry?
- Surveying structures or property
- Creating photographic maps
- Producing fully immersive 3D visuals
- Documenting on-ground conditions for construction teams.
What does LIDAR stand for?
Light Detection and Ranging.
What is the primary function of LIDAR?
Uses points of light to create detailed maps of objects’ positions in space.
What are some applications of LIDAR?
- Automated driving technology
- Augmented Reality (AR)
- Measuring height and density of land and vegetation.
What is the role of guidance systems in machine control?
Controls cutting-edge equipment through automation and connects to hydraulics while the operator manages the equipment.
What are the benefits of using laser augmented GPS?
- Near exact position of vehicle in real time
- High degree of accuracy
- No grade checker needed.
What can 3D camera systems create?
Virtual tours of free space and 3D renderings of locations.
How do digital artist impressions benefit clients?
Help clients visualize what a project will look like before building starts, serving as a proven selling tool.
What are the benefits of Virtual Reality (VR) in construction?
- Saves time and money
- Improves training safety
- Enhances collaboration
- Improves quality
- Shorter timescale.
What does Augmented Reality (AR) do?
Overlays digitally created content on top of the real world.
What are the limitations of AR?
- Expensive
- Not all headsets allow hard hats to be worn
- Distraction factor
- Health and safety risks
- Bad internet connections.
What are some benefits of using GPS guidance systems on construction sites?
- No stakes needed
- No grade checker needed
- Recorded data for quality control
- Real-time data transmission.
What is the purpose of structural analysis simulation?
Determines the effects of loads on physical structures and their components.
What types of structural analysis methods exist?
- Finite element analysis
- Hand calculations
- Prototype testing.
What are wind load simulations?
- Uplift load
- Shear wind
- Lateral load.
Define CGI in the context of building assets.
A 3D rendering process using computer software to create images.
What is the significance of augmented reality in underground asset mapping?
Helps view and map underground services prior to excavation, improving safety and efficiency.
What is 3D modeling?
The process of creating mathematical representations of a 3-dimensional object or shape using software.
What are NURBS?
Non-uniform rational basis splines, a mathematical model used in computer graphics to represent curves and surfaces.
What advantages does 3D construction offer?
- Error checking in drawings
- Better insight for surface patterns
- Virtual tours through walkthroughs
- Cost efficiency
- Improved collaboration.
