Reality Capture involves capturing and processing information from the real world to create accurate and detailed 3D digital models. It is a technique used in areas such as architecture, engineering and construction, among others. To carry out this technique, it is essential to have the right technology. Some of the best reality capture devices are:
- LiDAR cameraSome devices have already integrated it, for instance the current models of iPad Pro and iPhone Pro.
- 3D laser scanner
- Drone (it can work with some of the previous devices)
Reality capture devices for construction and engineering
Data capture for reality capture is very useful in construction because of all the benefits of creating a point cloud. It is important to know which reality capture device to use, depending on the purpose of your 3D scan.
Once have defined and select our device, we go to the construction site to capture the current as-built construction, creating a point cloud.
In some occasions, the data is processed and can be visualized in a 3D web viewer. It allows engineers, contractors and architects to improve planning, design and project management.
Data capture with LiDAR Camera
LiDAR camera devices are those that use LiDAR (Light Detection and Ranging) technology, which is based on the emission of laser light pulses to measure distance and create 3D maps of the environment.
This type of device offers significant advantages. First, it is capable of capturing precise and detailed details, such as shapes, textures and depths. They are able to capture data in very low light or even in complete darkness, making them ideal for indoors.
The most common devices to have a LIDAR camera are some high-end smartphones and tablets, although it is becoming more and more popular (i.e current models of iPad Pro and iPhone Pro). This technology improves the quality of the camera and enables the creation of 3D maps easily.
3D laser scanner
The 3D laser scanner uses lasers to measure distance and create 3D digital models of environments and objects. In architecture, it is used to create accurate and detailed models of existing buildings, allowing them to plan renovations, repairs or improvements. The most common types of lasers are:
- Terrestrial laser scanner: used on land and designed to scan large outdoor areas. They are very accurate and can capture data over long distances. It is set on a tripod. From each scanning position, the scan captures all the points and performs the data acquisition of those planned..
- Laser SLAM (Simultaneous Localization and Mapping): it is based on a laser sensor on a vehicle or robot. It allows the creation of a three-dimensional map in real time and the simultaneous localization of the vehicle on the map using laser sensors.
- Mobile laser scanner: this type of scanner is mounted on a vehicle and is used for large outdoor areas. They are faster and more efficient than terrestrial scanners, but less accurate.
- Handheld laser scanner: this is a portable scanner that is used for small objects or indoors. They are fairly accurate and easy to transport, but are usually slower in processing data than terrestrial or mobile scanners.
Drone data collection
Drone data capture refers to the use of drones equipped with cameras and other sensors (i.e: LiDAR) to gather information in different situations
Drones can capture data from areas that are difficult or dangerous to reach. Also they are able to cover large areas in a short time and with high accuracy, saving time on inspection and mapping projects.
To achieve the best reality capture results, it is important to use the right device These technologies are often expensive and sometimes data is not properly captured due to lack of experience.
