Construction and Inspection Drones

Here are six ways that drones for construction inspection and drone construction inspection are revolutionizing the field.

Here's how drones are being used in construction and inspection:

1. Site Surveying: Drones for construction inspection allow you to quickly survey a site, gathering accurate data to create 3D models or topographic maps. This data can be used for site planning, design, and management.
2. Building Inspections: Want to inspect that hard-to-reach spot on the rooftop? No need for a ladder or scaffolding. Just send up a drone and get all the details you need without breaking a sweat. Plus, it saves time and avoids the risks of accidents.
3. Progress Monitoring: Drones can provide real-time updates on construction progress, making it easier for project managers to monitor workflows, allocate resources efficiently, and make informed decisions.
4. Thermal Imaging: Some of the best drones for building inspection come equipped with thermal imaging cameras. These are particularly useful for detecting issues related to insulation, water leaks, or electrical problems.
5. Structural Inspections: Inspecting large structures like bridges, dams, or towers has never been easier. Drones provide high-resolution images and videos to catch structural issues or wear and tear.
6. Safety Compliance: Drones can be used to monitor a construction site for safety compliance, ensuring that all safety protocols are being followed and identifying potential hazards.
7. Volumetric Analysis: Need to measure huge amounts of materials on a site? Drones with LiDAR or photogrammetry come in to analyze the volumes of materials on construction sites, such as earthworks or stockpiles.
8. As-Built Surveys: Once your project is done, drones can do a final sweep to provide data for facility management and future maintenance.
9. Risk Assessment: By providing an aerial perspective of a construction site, drones can assist in identifying potential risks and planning for risk mitigation.
10. Documentation: Drones can capture high-quality images and videos of a construction project, which can be used for marketing purposes, client updates, or project documentation.

Each of our professional drone kits are designed to quickly, safely and efficiently provide you with actionable data. Ultimately, determining which solution is best depends on your specific needs, and which sensor/camera payload technology is best suited to capture that data.

Main Types of Sensors

Whether you work in urban planning or land surveying and need an aerial surveying solution to easily capture drone images for use in digital elevation models or you require the absolute accuracy of LiDAR to generate point cloud digital terrain models, or radiometric thermal imaging to quickly and safely acquire accurate measurements of industrial infrastructure heat signatures, DSLRPros has specific equipment tailored to that use case.

Most drones payloads incorporate one or more of these three types of imaging sensors-

Optical Cameras

Payloads like the DJI Zenmuse H20 or Zenmuse P1 capture very high resolution images in the visible spectrum.  In other words, they capture traditional photos and videos.  But these are more certainly not your average drone cameras for taking selfies and vacation videos.  Each payload carried utilizes highly sophisticated drone mapping technology and precise gps coordinate data that is shared with the airframe.  When paired with the M300 drone, these payloads are able to capture data that can be used for a variety of specialty use cases.

The P1 is a full frame camera specifically designed for drone photogrammetry. Photogrammetry is the process of gathering numerous aerial photographs of a subject and transforming them into high-resolution 2D or 3D models from which precise measurements may be deduced. This can be accomplished with specialized drone mapping software used for image processing that finds common features in images and combines them to construct a photo mosaic that accurately depicts a place.

Orthomosaic Mapping

Using different photogrammetry software can result in different outputs from the aerial data and images captured, such as orthomosaic maps, 3D point cloud models, and Digital Surface Models.

Photogrammetry can also be used to accurate volumetric measurement, allowing for data analysis of the resulting 3D map, which provides a very accurate model from which measurements of materials and supplies can be easily made.

The H20 is a high resolution 20 MP camera that offers an incredible 23x hybrid optical zoom with active image stabilization and EIS- perfect for drone inspection uses where you need detailed imagery but can't get too close to the subject.  With a 1200m laser rangefinder, night scene mode and an IP44 rating, the H20 is a powerhouse tool for professional drone operations.

Thermal Sensors

Unlike Optical sensors, thermal sensors don't capture light that we can see with the naked eye.  They capture heat.  More specifically, they capture infrared radiation that objects emit, known as a heat signature.  Thermal cameras with radiometric capabilities are able measure the exact temperature of any item in their field of view.

This data is incredibly important in industrial inspection. Accurate temperature data can be used to determine errors or issues in a number of inspection scenarios.

During a building or roof inspection, thermal aerial images can help pinpoint where insulation is thin and heat is escaping.  This imaging ability allows you to safely and quickly check the status of a building to find defects, leakages, and corrosion issues without needing to spend on additional personnel and equipment.

Thermal drones are often used to inspect solar panels.  As the drone flies over the solar panels, it is able to take a wide image of the surface, and very easily detect thermal anomalies which signal an issue.

Thermal camera images are able to be customized for different types of data analysis through the use of various color palette settings.

The thermal imaging color palettes typically range from a hot white configuration in which hot items are displayed in white and cooler ones in black, to a hot black configuration in which the color patterns are reversed. Color palettes can show heat in different ways, such as the rainbow setting, which displays the hottest items as red, yellow, or orange, while the coldest are displayed as blue or black.

There are many exciting thermal payloads available for different use cases.

For drone pilots who want to be able to capture both optical and thermal imagery, many commercial drones offer Electro-Optical/Infra-Red (EO/IR) solutions that integrate both visible and thermal sensors.

This is helpful when an inspection requires the ability to take accurate heat measurements, as well as traditional images, which can aid in identifying any externally visible damage to the subject, or aid in locating the exact spot that needs repair.

The DJI H20T is a EO/IR version of the H20.  It offers the same specs as the H20, but with the added benefit of an integrated radiometric thermal camera. The Mavic 3 Enterprise Series, Autel EVO II Enterprise 640T, and the Autel Evo II DUAL R also include dual sensors.

The FLIR Vue TZ20-R is a unique payload as it offers something others don't.  With two thermal sensors with different focal length lenses, the TZ20-R is able to provide thermal imaging at up to 20x zoom with far more clarity than competitors.  Because of the dual sensors, the TZ20-R has four times as many thermal pixels on target as other thermal payloads, which rely on digital enhancement to get a closer look at the subject.  This results in a blurrier picture the more the image is zoomed in.

While not a EO/IR payload on its own, the TZ20-R can be paired with an optical payload like the H20 on the M300 or M200 v2 series platforms using a dual mount.  This allows for the simultaneous capture of both spectrums.

LiDAR

One of the most exciting technologies to become much more accessible with the rising popularity of drone surveying and inspections is LiDAR.

LiDAR, which stands for Light Detection and Ranging, involves sending laser pulses and determining how long it takes for the lasers to return to the sensor. With the help of inertial measurements and satellite positioning data, the drone's LiDAR sensor can determine exactly where a point is located in space.

LiDAR point clouds are formed by combining these points with specialized point cloud software. The method is highly accurate, though the maps need to be paired with other data to add more detail, including color.

Compared to other methods used by mapping drones, LiDAR is excellent for mapping very small items. LiDAR data, for instance, can be used to generate a point cloud that includes thin cables and electrical lines. In addition to being able to work in low-light conditions, the technology can also penetrate through thick foliage to collect spatial data, resulting in an accurate digital terrain model.

A second advantage is that, since LiDAR point clouds are direct measurements, they have a relatively smaller file size than high-resolution photographs used in photogrammetry. As a result, it is faster to post-process LiDAR survey data than photogrammetry models, which can be very valuable for customers who prioritize efficiency or want to complete an aerial mapping mission within a fixed time.

The DJI L1 is a compact and affordable LiDAR + RGB aerial survey solution for the M300.

The L1 integrates a Livox Lidar module, a high-accuracy IMU, and a RGB (optical) camera with a 1-inch CMOS sensor, all on a 3-axis stabilized gimbal. When used with the P1 and the DJI Phantom 4 RTK, the L1 becomes a triple-sensor solution for aerial surveying, capable of producing photogrammetry, LiDAR point clouds, and high accuracy PPK results. This package is a one-box-solution for creating a digital twin from above and can be used for a wide range of applications.
