Depth Estimation: A Solution for Earth Volume Measurement

Based on Patent Research | US-11441291-B2 (2022)

Accurately determining the volume of excavated earth presents a persistent challenge in mining and quarrying operations. Traditional methods often lack precision, requiring manual checks that slow down workflows and increase costs. Depth estimation, a computer vision task, directly addresses this. It uses sensor data to measure distances, creating precise 3D digital terrain models of excavated areas. Automating this volume checking enhances site modeling, speeds up excavation processes, and reduces operational expenses.

SOLUTION OVERVIEW

Reimagining Manual Volume with AI Analysis

Depth Estimation technology directly addresses the persistent challenges of accurately measuring excavated earth volumes in mining and quarrying operations. It works by utilizing specialized sensors to capture detailed spatial data, which is then processed to construct precise 3D digital terrain models. These models allow for continuous, automated calculation of material quantities, moving beyond the inaccuracies and delays of traditional manual methods. This objective data provides a clear picture of site progress, enhancing overall operational visibility.

This automated approach significantly streamlines workflows by reducing the need for labor-intensive, time-consuming manual checks. The technology integrates seamlessly with existing site management systems, providing consistent, reliable data for better resource allocation and planning. Consider it like a surveyor instantly knowing the exact volume of a spoil pile or pit after every shift, without needing to physically measure it. This capability enables more efficient operations, optimizes material handling, and supports enhanced decision-making across the entire mining lifecycle.

HOW IT WORKS

Processing Scans for Earth Volume

Collecting Spatial Site Data

Specialized sensors continuously gather detailed spatial information across the mining or quarrying site, capturing every contour. This raw data includes precise measurements of distances and surface elevations, forming the essential input for subsequent analysis. It ensures a comprehensive understanding of the physical environment.

Generating Accurate Depth Maps

The system processes this raw sensor data to perform the core depth estimation task, creating highly accurate depth maps of all excavated areas. These maps precisely represent the varying elevations and distances from the sensors to the ground. This critical step translates raw measurements into a structured visual format.

Building Precise 3D Models

These generated depth maps are then expertly utilized to construct precise 3D digital terrain models of the entire operational area. This creates a comprehensive virtual representation, capturing every detail of the excavated earth and existing topography. These models serve as the accurate foundation for all volumetric calculations.

Quantifying Excavated Material Volumes

Finally, the detailed 3D models enable automated and continuous calculation of excavated material quantities with high precision. This provides objective, real-time data for optimized resource allocation, inventory management, and enhanced operational planning. Operators gain clear insights into site progress, improving decision-making.
