The remote sensing technique known as LiDAR (Light Detection and Ranging) uses laser light to measure distances and build accurate three-dimensional models or maps of objects and environments.
LiDAR in construction refers to the use of this technology in the building sector to enhance a number of planning, design, execution, and monitoring processes.
Due to its capacity to deliver precise and high-resolution data regarding topography, existing structures, and development progress, LiDAR is extremely useful in the construction industry.
Here are a few applications using LiDAR in construction:
Site mapping and surveying: Construction sites’ rich topographical data, including existing structures, trees, topography, and other features, may be swiftly and precisely captured using LiDAR.
This information can be utilized to produce precise site models and maps, which will help with project planning and design in its early phases. LiDAR can provide accurate measurements of elevations, volumes, and cut-and-fill requirements, which can help with grading and earthwork calculations.
This enhances the efficiency of the earthmoving and site preparation processes. Verification of the Design: LiDAR data can be compared to the project’s design plans to ensure that construction is continuing as planned.
Early detection of design deviations enables prompt modifications and decreases errors. Monitoring the Progress of Construction: LiDAR scans can be performed at different stages of construction to produce precise as-built models.
To track development and spot any differences from the initial concept, these models can be put side by side. Quality Control and Inspection: LiDAR is a tool that may be used to do quality control inspections to find flaws, inconsistencies, and design deviations.
This can lessen work and enhance the quality of construction. LiDAR technology is improving and becoming more practical and affordable for use in construction applications. It offers helpful insights to industry professionals, lowers project risks, increases productivity, and adds to the overall success of building projects.
The Global LiDAR In Construction Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Innoviz demonstrated its recently unveiled Innoviz360 system, which the company claims breaks through the performance, size, and cost restrictions that currently exist for spinning LiDAR.
The Innoviz360 has a 300m range, 0.05°x0.05° resolution, variable frame rate, and up to 1,280 scanning lines per frame.
Its architecture makes use of a single laser, detector, and ASIC, as well as other hardware improvements over its predecessor, the InnovizTwo.
Achieving Level 4-5 automation in applications like robotaxis, shuttles, trucks, and delivery vehicles may present significant hurdles for original equipment manufacturers (OEMs), but the Innoviz360’s high resolution, great vertical field of view, and low cost may help.
Additionally, it makes autonomy possible in non-automotive applications including heavy equipment, smart cities, logistics, buildings, and more.
