Pix4D is a suite of software products that use photogrammetry and computer vision algorithms to transform both RGB and multispectral images into 3D maps and models.

Volume measurement with Drones is an extremely fast, accurate and cost-effective method to analyze volumes on your maps from any device. User tests have found that when following best practices Drone's volume measurements are accurate within 1-2% of traditional ground-based laser measurements.
Sometimes a 3D representation isn’t enough to get the job done, so we wanted to provide a tool that combines the best of both worlds in a single environment. The rayCloud provides a seamless integration between a 3D representation of the project area and the original images.
The accuracy of a volume measurement depends on the quality of the reconstruction and on how well the base surface is defined. This means that I would first make sure that the project itself is well reconstructed by checking the quality report and the point cloud.
