When it comes to collecting field data, every minute counts. You don't want to spend hours measuring a single distance or contour when there are dozens more measurements to take. This is where handheld LiDAR (Light Detection and Ranging) technology comes into play. By using a handheld scanner, field data collection can be done quickly and accurately, reducing errors and speeding up the process. In this article, we will delve into the advantages of handheld LiDAR for field data collection and how this technology can revolutionize the way data is collected in various fields.
What is Handheld LiDAR?
LiDAR technology is used to measure distances and map features by sending out pulses of light and measuring the reflections. This technology is commonly used in various fields, including surveying, forestry, archaeology, and construction. Traditional LiDAR systems are large and expensive, mounted on aircraft or vehicles, but handheld LiDAR systems are small, portable devices that can be used by individuals in the field.
Handheld LiDAR is a device that combines a laser rangefinder, a digital camera, and an Inertial Measurement Unit (IMU) to accurately capture and record data. The device calculates a set of points and creates a 3D map of the area being scanned. The system can capture high-resolution data points in a matter of seconds and generate more comprehensive maps than traditional measurement methods.
Advantages of Handheld LiDAR for Field Data Collection
Handheld LiDAR has several advantages that make it an excellent choice for field data collection. Below are some of the benefits that handheld LiDAR offers:
Time-Saving and Efficient Data Collection
Handheld LiDAR systems have significantly reduced the time required to collect data in the field. With conventional methods, field data collection is a lengthy process that requires many tools and takes several hours to complete. In contrast, handheld LiDAR can provide accurate data in seconds, substantially reducing the time required to collect data. The system can capture high-resolution data points and generate more comprehensive maps than traditional measurement methods. This means the surveyors can map larger areas in less time, resulting in higher productivity and efficiency.
Increased Accuracy
Handheld LiDAR can deliver highly accurate data without physical contact. Unlike traditional surveying methods, handheld LiDAR does not require physical contact with the object being measured, allowing surveyors to cover large areas without disturbing the natural environment. This reduces the chances of errors and inaccuracies introduced due to the surveyor's fatigue or limitations, leading to more accurate and reliable results.
Cover More Challenging Terrain
Handheld LiDAR can cover more challenging terrain, including steep and inaccessible areas, that were previously impossible, dangerous, or cost-prohibitive to access. The handheld laser scanner can effectively capture data and generate accurate maps even in rocky, hilly, or heavily vegetated areas.
Reduced Post-Processing Time
Post-processing the collected data in traditional methods requires significant human involvement and can take several days to complete. In contrast, handheld LiDAR systems can transmit the data to a cloud server or local computer, where it is automatically processed within minutes. This reduces the time and cost of data processing, allowing surveyors to receive and analyze the results faster.
Cost Savings
Handheld LiDAR technology ultimately reduces the cost associated with field data collection. The traditional methods of data collection require an enormous amount of time, tools, and personnel, leading to nearly infinite labor costs. The handheld LiDAR technology saves time and resources, allowing companies and surveyors to accomplish more data collection in less time. The lower cost of data collection and processing translates to less time and money spent on the project.
Applications of Handheld LiDAR for Field Data Collection
Handheld LiDAR technology is used in various fields, including surveying, engineering, construction, forestry, mining, and archaeology. Below are some of the examples of applications of handheld LiDAR technology.
Forestry Management
Forestry management is a complex process that requires accurate mapping of forested areas, including tree species, growth rates, root development, and forest structure. Handheld LiDAR technology provides highly accurate measurements of tree heights, stem diameters, and canopy structure, which are crucial parameters for forest growth modeling. Accurately measuring these attributes allows forest managers to optimize the forest growth rate, distribution, and harvest.
Archaeological Surveys
Handheld LiDAR technology has revolutionized the way archaeological surveys are conducted. The technology allows archaeologists to capture precise digital models of historical buildings, architectural features, and other objects of interest. The technology can also be used for detecting archaeological features hidden in thick vegetation or obscured by soil layers, reducing the amount of excavation and excavation work needed.
Construction Management
Handheld LiDAR technology is widely used in construction management to generate accurate site models, topographic features, and building fa?ades. The technology allows the site managers to take measurements, perform quality control assessments, and monitor progress with high accuracy and efficiency.
Conclusion
Handheld LiDAR technology offers several advantages over traditional surveying methods in various fields, including forestry management, archaeology, and construction. The technology allows for faster, more accurate, and efficient data collection with less environmental disturbance and cost savings. Handheld LiDAR technology will likely become more prevalent in the future as it continues to become more affordable, accessible, and easier to use. As the technology advances, it is likely that handheld LiDAR technology will allow surveyors to collect even more comprehensive data in less time, revolutionizing the way data is collected and analyzed.
