Description

基于LiDAR技术对建筑进度管理的系统
本发明涉及一种利用LiDAR技术对建筑物进行测量并与BIM进行对比以实现对建筑进度及建筑商，物业管理商，及运营商进行管理的系统。
BIM（Building Information Modeling建筑信息模型）可以帮助实现建筑信息的集成，从建筑的设计、施工、运行直至建筑全寿命周期的终结，各种信息始终整合于一个三维模型信息数据库中，设计团队、施工单位、设施运营部门和业主等各方人员可以基于BIM进行协同工作，有效提高工作效率、节省资源、降低成本、以实现可持续发展。
BIM的核心是通过建立虚拟的建筑工程三维模型，利用数字化技术，为这个模型提供完整的、与实际情况一致的建筑工程信息库。该信息库不仅包含描述建筑物构件的几何信息、专业属性及状态信息，还包含了非构件对象（如空间、运动行为）的状态信息。借助这个包含建筑工程信息的三维模型，大大提高了建筑工程的信息集成化程度，从而为建筑工程项目的相关利益方提供了一个工程信息交换和共享的平台。
在使用BIM等软件对建筑模型进行管理外，在建筑物的施工过程中为了保证大型建筑工程能够按照既定的工程建设进度安排进行实施，需要对建筑工程进度进行监理，其中工程质量是最为重要的部分。但现有对建筑工程进度监理的过程是指派监理人员定期到施工现场对已完成的工程进度进行度量及检查，看是否符合施工要求。但是传统的监理过程无法实时利用BIM模型对工程的质量及进度进行跟进。
针对上述现有技术的不足，本发明提供了一种基于LiDAR技术对建筑进度管理的系统，用户可以通过使用手持LiDAR设备对建筑现场进行实时扫描以获取测量数据，然后将实时的测量数据与历史测量数据进行比对，以实现工程进度的实时检查。
本发明是这样实现上述目的的：
基于LiDAR技术对建筑进度管理的系统，包括基于云端的服务器以及手持测量设备，手持测量设备中设有LiDAR以及定位装置；使用上述装置对建筑物的建筑进度的管理方法包括以下步骤：
S1.持手持测量设备进入建筑物中，利用手持测量设备的LiDAR对建筑物进行测量并记录测量数据，同时定位装置记录测量位置的定位数据；
S2.手持测量设备实时将测量数据及定位数据传输至云端的服务器，服务器记录下测量数据、定位数据以及测量时间；并根据定位数据调取该定位位置过往所记录的历史测量数据，将实时的测量数据与历史测量数据进行比对，生成比对结果数据；
S3.服务器将对比结果数据实时传输至手持测量设备，手持测量设备将对比结果数据通过显示装置实现增强/混合现实显示。
其中，所述手持测量设备还设有摄像装置，摄像装置在LiDAR对建筑物进行测量时同步记录图像数据，并传输至云端的服务器。
其中，步骤S3中，手持测量设备将对比结果数据转换为图形数据并迭加至摄像装置的图像数据中，再送至显示装置实现增强/混合现实显示，具体步骤为：服务器设置指定的误差值，将测量数据与过往所记录的历史测量数据对比并计算偏差值，如偏差值在误差值内，则认为测量数据与过往所记录的历史测量数据一致；否则认为测量数据与过往所记录的历史测量数据不一致，并将偏差值形成质量检测数据，并将质量检测数据在显示装置中突出显示。
其中，所述服务器中还装载有正在施工建设的建筑物BIM，将实时的测量数据与BIM数据进行对比，进行建筑质量管理，具体包括以下步骤：手持测量设备实时将测量数据及定位数据传输至云端的服务器，服务器根据定位数据取得建筑物BIM中与定位数据相对应位置的BIM数据，将测量数据与BIM数据进行比对，生成质量检测数据；服务器将质量检测数据实时传输至手持测量设备，手持测量设备将质量检测数据通过显示装置实现增强/混合现实显示。
其中，服务器设置指定的误差值，将测量数据与BIM数据对比并计算偏差值，如偏差值在误差值内，则认为测量数据与BIM数据一致；否则认为测量数据与BIM数据不一致，并将偏差值形成质量检测数据，并将质量检测数据在显示装置中突出显示。
其中，所述建筑物BIM中存储有建筑构件的属性数据，云端的服务器实时将建筑构件的属性数据传输给手持测量设备，手持测量设备的显示装置实时展示属性数据。
其中，测量数据与BIM数据不一致，手持测量设备实时将测量数据所形成的图形数据在显示装置显示突出显示并发出警示。
其中，所述定位装置包括分布安装于建筑物中以及设置于手持测量设备中进行通信的可见光无线通信装置，手持测量设备中的可见光无线通信装置与建筑物的其中一可见光无线通信装置连通时，根据建筑物可见光无线通信装置的设置位置对手持测量设备进行定位；同时手持测量设备通过可见光无线通信装置连接至云端的服务器。
其中，所述定位装置为iBeacon定位设备或为设置于建筑物现场中的QR Code, Barcode，RFID及室内移动网络，如4G、5G等定位设备。
其中，所述云端的服务器运用基于区块链的数据存储，包括测量记录及时序数据库、建筑物构件属性数据库、建筑物BIM数据库、用户权限及资料数据库。
本发明的有益效果：用户通过手持式LiDAR到建筑物的指定位置对该处的建筑结构、构件及设备等进行扫描，并实时获得现场的建筑结构、构件及设备的3D测量数据，即点云数据（point cloud data），通过网络传送至云端的服务器。因每次对使用LiDAR对建筑物进行扫描时都会在服务器中形成当时的测量数据，将不同时间的测量数据进行比对即可以清晰的获取建筑物的建筑进度。用户对建筑结构、构件及设备进行实时扫描时，通过实时测量数据与历史测量数据进行对比即可实时获取对比结果，然后再通过手持测量设备的显示屏幕采用增强/混合现实显示技术（Augmented Reality/Mixed Reality）将对比结果进行显示，例如用不同的颜色显示实时扫描获取并识别已经完成建筑物构件以及以往完成的建筑物构件等，或实时显示应有设备的存放数量及位置等，使得用户可以快速、直接、清晰的了解到那些工程已经完成、进行中等建筑构件属性等资讯，用以更加方便的了解到建筑进度，并进行项目进度记录及汇报，并通过云端系统自动或手动通知有关人员跟进。

实施例
参照图1至图3所示，基于LiDAR（Light Detection and Ranging，光学探测与测量，又称光学雷达）对建筑进度管理的系统，包括基于云端的服务器，所述服务器中装载有正在施工建设的建筑物BIM；以及手持测量设备，手持测量设备中设有LiDAR 1以及定位装置。其中所述手持测量设备可以是手提电脑、手机或平板电脑等，如苹果公司的iPad Pro2020，在其摄像头的位置设置了LiDAR 1模块。由于建筑物内无法接受GPS信号，因此其定位装置需要采用可以实现室内定位功能的相应技术，如目前市面上常见的QRCode、RFID、Wifi、UWB、蓝牙、红外、超声波、ZigBee、室内移动网络如4G、5G等室内定位技术，其中苹果公司的iBeacon定位技术是直接采用手机或平板电脑内的蓝牙模块，与外置的iBeacon通信模块进行通信并定位。
除上述定位装置外，还可以采用可见光无线通信（Visual Light Communication，简称VLC）技术实现室内定位，需要在建筑物内按照需要将VLC装置分布设置与建筑物内。VLC的工作原理是利用LED灯通过PWM技术将数据转化为高频的明暗闪烁信号实现通讯，由于频率较高，人眼无法察觉到LED灯的闪烁，并不影响正常的照明，而且通信只能在LED灯所发出的可见光所覆盖的范围内有效，相应的手持测量设备中也设置VLC装置，当手持设备进入某VLC装置的光范围内进行通信时，即可根据建筑物中该VLC装置的位置进行定位。同时手持测量设备还可以通过VLC装置连接至云端的服务器进行数据传输。
通过室内定位装置，能够实时记录用户使用LiDAR 1对建筑物进行测量时的位置，并将定位数据和LiDAR 1测量的点云数据传输至云端的服务器，以便于服务器能够将根据定位数据找到BIM中相应位置的模型数据与点云数据进行对比。同时服务器也记录下测量时间，通过时间记录实现工程进度的管理。
使用上述装置对建筑物的建筑进度的管理方法包括以下步骤：
S1.用户按照预定的监理进度持手持测量设备进入建筑物的指定检测位置，利用手持测量设备的LiDAR 1对该位置的工程构建进行测量形成点云数据，同时定位装置记录测量位置的定位数据。
S2. 手持测量设备通过无线网络，如移动数据网络、Wifi、蓝牙等，实时将点云数据以及定位数据传输至云端的服务器并记录测量时间，服务器获取到点云数据及定位数据后可进行建筑进度管理及建筑质量管理。
其中建筑进度管理：云服务器首先会根据定位数据从数据库中调取该定位位置过往所记录的历史测量数据，一般为上一次完成的测量数据，将实时的测量数据与历史测量数据进行比对，以发现实时测量的数据与历史测量数据的差别，而该差别就是此段时间完成的施工进度；然后服务器会记录这些差别并形成比对结果数据。
其中建筑质量管理：服务器根据定位数据从建筑物的BIM中取得该应位置的BIM数据，云端服务器利用点云数据构建出现场实时的3D建筑模型，将3D建筑模型与BIM数据进行比对。具体为将点云数据与BIM数据对比并计算偏差值，如偏差值在误差范围内，则认为该建筑构件的点云数据与BIM数据一致，建筑构件的规格符合BIM设计的要求。但如果偏差值超出误差范围，则可能是建筑构件没有完成或建筑构件的规格超出BIM设计的要求，服务器将记录偏差值形成对比结果数据。
S3.服务器也实时的将对比结果数据实时传输至手持测量设备。手持测量设备除了设有LiDAR 1对建筑物进行测量外还会设有摄像装置2，如拍摄镜头等，用于实时记录LiDAR 1所测量的建筑构件的图像信息同时将图像信息在其显示屏上实时显示。同时将对比结构数据转换为图形数据迭加在拍摄镜头的实时图像上进行显示，实现增强/混合现实技术的显示并发出警示，例如建筑构件规格符合BIM内的设计，则可在实时拍摄的建筑构件外渲染不同的确认颜色，如绿色、蓝色等的外轮廓；如建筑构件规格不符合BIM设计的要求，则将BIM内的设计数据用警报颜色，如红色、橙色、黄色等外轮廓线进行显示，用户可通过上述技术从手持测量设备直观的观察测量位置的所有建筑构件是否符合BIM内的设计，以便于用户可以方便地实时观察到建筑物中各个建筑构件的工程进度及质量等等。
另外，建筑物BIM中还会存储有建筑构件的属性数据。由于建筑现场的建筑构件可能未有完成且没有识别标签，用户可能无法通过直接观察来识别建筑构件，而通过点云数据与BIM对比，服务器可智能识别出点云数据中的不同建筑构件，然后再实时将识别的建筑构件的属性数据传输给手持测量设备，如包括建筑构件的名称、规格、要求等等，手持测量设备的显示装置可以实时向用户展示各种建筑构件的属性数据，以便用户可以快速识别并进行检查。
上面提及的建筑进度管理及质量管理并不只限定于建筑物或建筑构件的施工，还可能涉及到建筑物BIM设计中其他物件的安装与布置，例如建筑物管道的铺设，消防物品、照明灯、指示标志的放置、数量及规格等等。只要BIM设计中所涉及的所有物件，均可以利用本发明所提供的系统及方法对建筑进度及质量进行有效的管理。此功能不只限于施工中的建筑物内使用，更可延展至已运营中的建筑物上，给予物管人员更方便快捷的管理。
为了保证云端数据的可靠性，云端的服务器采用基于区块链的数据存储，包括测量记录数据的数据库、建筑物BIM的数据库，区块链技术能够确保数据被保存后不被修改，从而确保数据的可靠性及法律效力。
系统还可以针对不同的人员，设置不同权限的用户。每一个用户利用LiDAR 1扫描资料都可以作为其他相关及/或项目用户的参考数据。

  5. 根据权利要求4所述基于LiDAR技术对建筑进度管理的系统，其特征在于：服务器设置指定的误差值，将测量数据与BIM数据对比并计算偏差值，如偏差值在误差值内，则认为测量数据与BIM数据一致；否则认为测量数据与BIM数据不一致，并将偏差值形成质量检测数据，并将质量检测数据在显示装置中突出显示。
  6. 根据权利要求4所述基于LiDAR技术对建筑进度管理的系统，其特征在于：所述建筑物BIM中存储有建筑构件的属性数据，云端的服务器实时将建筑构件的属性数据传输给手持测量设备，手持测量设备的显示装置实时展示属性数据。
  7. 根据权利要求4所述基于LiDAR技术对建筑进度管理的系统，其特征在于：测量数据与BIM数据不一致，手持测量设备实时将测量数据所形成的图形数据在显示装置显示突出显示并发出警示。
  8. 根据权利要求1所述基于LiDAR技术对建筑进度管理的系统，其特征在于：所述定位装置包括分布安装于建筑物中以及设置于手持测量设备中进行通信的可见光无线通信装置，手持测量设备中的可见光无线通信装置与建筑物的其中一可见光无线通信装置连通时，根据建筑物可见光无线通信装置的设置位置对手持测量设备进行定位；同时手持测量设备通过可见光无线通信装置连接至云端的服务器。
  9. 根据权利要求1所述基于LiDAR技术对建筑进度管理的系统，其特征在于：所述定位装置为iBeacon定位设备或为设置于建筑物现场中的QR Code, Barcode，RFID及室内移动网络定位设备。
  10. 根据权利要求1所述基于LiDAR技术对建筑进度管理的系统，其特征在于：所述云端的服务器运用基于区块链的数据存储，包括测量记录及时序数据库、建筑物构件属性数据库、建筑物BIM数据库、用户权限及资料数据库。
