大型露天料场激光测量方法研究

针对当前大型露天料场测量由于没有载体安装测量设备而采用人工测点测量方法导致效率低、周期长、精度差和人为影响大的问题，提出了在车载平台上安装伸缩机构，集成激光扫描仪、惯性制导、全球定位系统和电子云台，对料场采用分区独立扫描测量，统一坐标变换合并的方法，快速获取料场三维坐标数据，准确计算料场体积从而实现储量换算，实验条件下绝对精度达0.4%。露天堆场现场测试表明8000 m2分十区测量能在1 h内完成，重复测量误差小于0.9%，矿山测量没有现场实验，依据设备参数推算精度要低于以上结论，但能满足行业测量需要。该方法有效解决了散堆露天料场的测量问题，能广泛应用于露天堆场、矿山测量，具有良好的应用前景和推广价值。

Abstract

Artificial measuring point measurement method is used for measurement in large open-air stockyard because of no carrier installed measurement equipment, which can result in low efficiency, long life cycle, poor accuracy and man-made influence. To solve above problem, telescoping mechanism installation on the vehicle platform is proposed. Laser scanner, inertial navigation, GPS and electronic pan/tilt/zoom (PTZ) are integrated, and partition independent scanning measurement of stockyard and unified coordinate transformation combination are used to quick access to the stockyard 3D coordinate data and to accurately calculate the size of the stockyard enabling reserves converter. Under test conditions, the absolute accuracy is up to 0.4%. Open yard field tests show that the separated ten districts measurement of 8000 m2 can be completed within one hour with the error of repeating measurement less than 0.9%. Field test of mine surveying isn′t taken and the accuracy is lower than the above conclusions based on the device parameters, but it can meet the measurement need of the industry. This method is an effective solution to the measurement problem, and can be widely used in the open yard, mine surveying, with good application and promotion prospects.
