What is a Point Cloud Survey?
In 3D laser scanning, technology maps millions of points throughout the entirety of a building or space. These points help to accurately capture and measure the dimensions and physicality of varying objects of all shapes and sizes. Rather than rely on physical measuring standards, architects, designers, and project managers use laser scanning to accurately pinpoint vertices, corners, edges, elevations and more. This process involves creating a point cloud file and is often referred to as a point cloud survey. Point cloud surveys can take place in spaces of all sizes and are particularly useful when measuring and analysing awkward architecture or interior fixtures which are difficult to reach.
From a point cloud survey, users can access data and manipulate it in various ways. To some, the process is known as 'scan to BIM'. A BIM is a Building Information Model and is a fully 3D object or walkthrough of a space. This will allow users to easily adapt, transform and edit their physical spaces in a variety of suites. Crucially, point cloud surveys and mapping will allow users and surveyors to carefully capture all the dimensions they need from a space to be able to work with it from afar. It has become the leading modern standard for building planning, both inside and outside of a premises. Laser scanners emit beams at exceptionally high speeds, with some of the best equipment able to plot a million or more points across a given area every second. Scanners capture data once laser beams hit objects and bounce back towards the tools, allowing users to capture large spaces and awkward interiors across three axes in X, Y and Z. This is superior to traditional measurement in the sense, too, that it offers zero room for human error. While many people prefer to continue measuring by hand, it is ultimately far more accurate and reliable to map points through a device for careful analysis and editing at a later date.
Data is easy to extract from laser scanning. Point cloud surveys allow you, initially, to completely analyse and move through a space before converting it all into a portable, shareable file. Point cloud files are easy to access and edit through various suites, and what's more, users will be able to use such data to transform into 3D BIMs and 2D drawings. This means that you will be able to push point cloud data into a number of file types for easy digestion and editing. There are plenty of benefits in running point cloud surveys, and not just in the simple data capture and flexibility. Point cloud data capture is amazingly cost-effective. Laser scanning and point manipulation will cut down on the need for costly and time-consuming labour hire and project setup. Therefore, it is entirely possible that 3D laser scanning will help to enhance your project efficiency and to reduce your overheads. It is little wonder why point cloud editing and laser scanning in general are quickly becoming leading standards in the industry.
