53197 然而,由于现场环境光照条件复杂、清水倒影、成像分辨率低和视角倾斜的影响,水尺表面字符和刻度线的识别相当不可靠。 However, due to the effects of complex on-site ambient lighting conditions, clear water reflection, low imaging resolution, and oblique viewing angles, the recognition of characters and tick marks on the water gauge surface is quite unreliable.
53198 为提高复杂光照条件下水位值的精度,本文设计了一种基于灰度拉伸的水位线检测方法。 In order to improve the accuracy of the water level value under complex lighting conditions, a detection method of the water level is designed based on grayscale stretching.
53199 首先,构造一种新的结合卷积神经网络(CNN)和残差的去噪模型,在去除水尺图片噪声的同时能够较好地保持水尺的细节。 First of all, a new denoising model is constructed based on residual learning and convolutional neural network(CNN), which can maintain the details of the water gauge while removing the noise of the water gauge image.
53200 然后,通过灰度直方图统计水面、背景、水尺部分的灰度值并进行分析,确定灰度拉伸的范围,明确水尺与水体部分的分界线来定位水位线。 And then, the grayscale histogram is used to count the grayscale values of the water surface, background, and water gauge, and analyze to determine the range of gray stretch, and clarify the boundary between the water gauge and the water body to locate the water level.
53201 矿产资源过度开采极易诱发地面塌陷等地质灾害,对矿区的生产生活造成了严重的威胁。 Excessive exploitation of mineral resources can easily induce ground deformation and other geological disasters, which poses a serious threat to the production and lives of the mining area.
53202 采用2017年5月至2018年11月21景Sentinel-1A数据,设置时间基线(365 d)和空间基线(2371 m)并生成连接图, 21 Sentinel-1 A scenes from May2017 to November 2018 are adopted, then a connection chart is generated by setting the temporal(365 d) and spatial(2371 m) baselines.
53203 采用小基线集技术(SBAS)对生成的影像对进行干涉处理,通过生成的干涉相位进行地面沉降的参数反演,获取了巨野煤田的形变场和监测点的形变序列。 Based on this, the image pairs are interfered by small baseline subset(SBAS) technique. The parameters of land subsidence are inverted through the generated interferometric phase, and the deformation field and point monitoring sequence of the Juye coalfield are obtained.
53204 结果发现,巨野煤田发生24 mm以上地面沉降的区域面积占比高达87. 12%,而郭屯矿区的地面沉降最为严重,中心沉降量超过70 mm,年沉降速率达到45 mm/a。 The results show that the cumulative settlement over 24 mm occurs in 87. 12% of the land in Juye coalfield, and the maximum land subsidence occurs in Guotun coal mine, the settlement rate is 45 mm/a and the cumulative settlement is more than 70 mm.
53205 巨野煤田的地面沉降由自然和人为因素造成,其中人为煤炭开采和地下水的过量使用是主要原因。 The land subsidence in Juye coalfield is caused by natural and human factors, of which the exploitation of coal mine and the overuse of groundwater are the main reasons.
53206 与水准测量的对比结果表明,二者沉降监测的总体趋势吻合。该项研究工作表明,小基线集雷达干涉测量(SBAS-InSAR)技术可以很好地应用于矿区沉降的监测, Compared with the leveling data, the overall trend of subsidence monitoring is consistent, which demonstrates that the surface deformation monitoring results based on the small baseline subset interferometric synthetic aperture radar(SBAS-InSAR) method are reliable.
