When it comes to surveying, photogrammetry with drones can be more efficient than LiDAR in several ways.
Firstly, photogrammetry can capture high-resolution images that provide a detailed representation of the terrain, allowing for accurate and precise measurements. Drones can capture images from various angles and altitudes, enabling the creation of 3D models with great detail. In contrast, LiDAR uses lasers to measure distances, and while it can create precise 3D models, it may not capture small details as effectively as photogrammetry.
Secondly, photogrammetry with drones can cover large areas in a short amount of time. Drones can fly over large swaths of land and capture images quickly, allowing surveyors to collect data efficiently. This process is particularly useful in areas that are difficult to access, such as rugged terrain, coastal areas, or wetlands. In contrast, LiDAR requires more time and resources to capture data and process it into usable 3D models.
Thirdly, photogrammetry is generally more cost-effective than LiDAR. LiDAR sensors and equipment are expensive, and the data processing requires specialized knowledge and training. In contrast, photogrammetry with drones is more accessible and requires less specialized equipment, making it more affordable and easier to operate for many users.
Overall, photogrammetry with drones can provide accurate and detailed 3D models quickly and cost-effectively, making it an efficient tool for surveying. While LiDAR can also be useful in certain situations, photogrammetry with drones is often a more practical and efficient option for many surveying projects.
