AI Technical Summary

Technical Problem

In tunnel blasting operations, traditional visible light imaging and manual sampling methods are difficult to accurately and in real time estimate the size of blasted fragments in complex environments. Existing infrared technology has failed to effectively combine fragment kinematic models, resulting in insufficient accuracy and safety in fragment size analysis.

Method used

By employing dual-band infrared imaging technology, combined with debris trajectory modeling, thermodynamic-morphological correlation analysis, and block size classification statistics, the system enhances debris edge identification by penetrating smoke with long-wave infrared and sensitive high-temperature targets with mid-wave infrared. By combining inertial motion equations and air resistance models, it achieves non-contact debris mass and volume measurement.

Benefits of technology

It enables accurate and real-time statistics of the size of blasted blocks in harsh environments, improves the image signal-to-noise ratio and target segmentation accuracy, avoids the safety risks and errors of manual sampling, and provides a scientific basis for parameter adjustment.

Abstract

本发明公开了一种基于红外成像的隧道爆破块度统计方法,涉及隧道工程爆破技术领域,所述方法包括以下步骤:S1、双波段红外成像:采用长波红外与中波红外双波段协同成像,穿透烟雾并增强碎片边缘识别;S2、碎片运动轨迹建模:通过高速红外摄像连续捕获碎片飞行轨迹,结合惯性运动方程,推算碎片初速度、加速度及抛物线特征。本发明通过双波段协同成像技术:LWIR波段穿透烟雾与灰尘能力优异,可在恶劣环境中获取碎片轮廓;MWIR波段对高温目标敏感,增强碎片边缘识别,双波段数据融合显著提升图像信噪比与目标分割精度,有效解决了传统可见光摄像在复杂爆破环境下成像质量差的问题。
