When it comes to collecting data with a lidar-equipped unmanned aerial vehicle (UAV), there are several steps that must be taken to ensure the accuracy and reliability of the data. This includes checking the alignment of the sensor, adjusting its settings, and performing a test flight to make sure the data is accurate. Additionally, it is essential to maintain and regularly update the sensor to guarantee it works properly. This may include cleaning the sensor, checking for damage, and updating the firmware.
Another common mistake made in lidar topography is not using the right flight plan. The flight plan for a lidar study with drones is critical for data quality, as it determines how the drone will collect the data and cover the study area. If the flight plan is not designed correctly, the data may be incomplete or inaccurate, which can compromise the entire survey. To avoid this, it is important to use a flight plan designed specifically for lidar inspection.
This usually means flying in a grid pattern, keeping the drone at a constant altitude and speed, and making multiple passes over the reconnaissance area. This allows the lidar sensor to collect data from different angles and ensure full coverage of the study area. It's also a good idea to use flight planning software to monitor the position and status of the drone. This allows you to make adjustments to the flight plan as needed to ensure that the data collected is accurate.
Another common mistake in lidar topography is not processing lidar data correctly. The lidar data collected by the drone must be processed and analyzed to help create maps and models. If the data is not subsequently processed correctly, inaccuracies in the final results can result and compromise the entire survey. It is essential to use software specifically designed for post-processing of lidar data.
This software will normally include tools for filtering, classifying, and analyzing data. It is also important to have a team of experienced professionals trained in lidar data post-processing to ensure that the data is processed correctly. ROCK Cloud post-processing software does most of the work for you and produces highly accurate, survey-friendly results. Our support team provides live support throughout the United States during business hours, checking the quality of each project before sending you the results.
ROCK Cloud produces products from any lidar file, including orthomosaics and images. By avoiding these three common drone lidar mistakes, your projects will be more successful, your data will be more accurate, and your customers will be satisfied. Meet with the ROCK Robotic sales team today to explore ROCK Lidar hardware and software. A lidar drone is a drone that carries a lidar sensor for data collection.
The data collected by lidar-equipped drones can be used to create 3D models down to the smallest detail, allowing users to identify features, structures or areas of interest in perfect detail. GCP Lidars are no different; however, the way they see is different from that of a typical RGB sensor, so there are some considerations to consider. With lidar drones, both the drone itself, its lidar sensor, and their integration are equally important. Different combinations of lidar sensors and drone models and designs will produce different types of results; in some cases, lidar may not be the best method for 3D modeling.
While integrating lidar sensors into commercial drones makes lidar mapping more affordable, cost remains difficult to estimate. As mentioned above, lidar drones and their associated sensors can save millions of dollars in several different sectors; since cost of entry continues to plummet, it's almost certain that lidar drone technology will continue to be implemented in several sectors. Next we'll discuss different ways in which lidar is currently used and discuss best lidar drone sensors currently on market. However, while there are all-in-one drones and full-service lidar packages available, best investment for hobbyists, enthusiasts or even smaller companies is high-quality lidar sensor.
This particular lidar integrates a lidar sensor with an RGB camera to simultaneously acquire point cloud data and visible light images; this results in high-density true color dot cloud with vertical accuracy greater than 2 cm without ground control points. These advances together with advances in technology used to integrate drones with lidar data have led rapid increase in number of companies using drones equipped with lidar as comprehensive full-scale 3D mapping system. The best lidar drone for building inspection may not be best for planning irrigation so it's important to know intended use case before buying lidar sensor. This lidar sensor detects targets with range up to 215 meters and has light weight of 75 grams making it fantastic lightweight lidar sensor that will work with several drones.
However lidar technology which used cost thousands dollars now only costs couple hundred dollars; in few years even these lidar sensors will start come down in price.
