[0003] Power infrastructure project progress management is an important part of power enterprise management. Combining project quality management, safety management, investment management and other factors to carry out management work can promote the development of power enterprises to a certain extent and make power infrastructure enterprises invincible in the fierce social economy. Progress management plays a very important role in all engineering projects, especially in power infrastructure construction projects.

[0004] The most intuitive feature of the Grid Information Model (GIM) is the three-dimensional visualization.

During the construction phase of the power infrastructure project, a large number of high-definition cameras will be configured on site. However, combining GIM technology with construction plans, construction simulations and on-site video monitoring, and using artificial intelligence to accurately judge the progress of power infrastructure construction has become a major problem facing the industry.

In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0038] Embodiment 1

[0039] like Figure 1 As shown, this embodiment provides a method for monitoring the progress of power infrastructure construction, which specifically includes the following steps:

[0040] Step 1: Obtain an initial three-dimensional model of the power infrastructure project, wherein the initial three-dimensional model of the power infrastructure project is a GIM model of the power infrastructure project.

[0041] In the preliminary design stage of power infrastructure projects, designers will establish a high-precision initial GIM model for the infrastructure. Specifically, based on the principle of "standard unification, compatible interaction, and universal model", a unified substation, converter station, and line universal model library is established by applying universal design and universal equipment. GIM's three-dimensional technology can be used to perform collision checks in the early stage, optimize engineering design, reduce the possibility of errors and rework that may exist during the construction stage, and optimize clearance and pipeline layout. Finally, construction personnel can use the collision-optimized three-dimensional pipeline plan to conduct construction briefings and construction simulations to improve construction quality, while also improving the ability to communicate with owners.

[0042] Step 2: Obtain the installation parameters (coordinate position and installation angle of each image acquisition device in each image acquisition device group) and rotation angle of each image acquisition device group at the power infrastructure project site, as well as the on-site pictures of the power infrastructure project collected by each image acquisition device group and the perception angle of each pixel point (observation point) in the on-site pictures, and crop out the overlapping observation area of ​​the on-site pictures collected by two image acquisition devices in each image acquisition device group.

[0043] As an implementation method, the image acquisition device is a camera or a webcam. When a webcam is used, the webcam transmits back the real-time acquisition of the live video, the camera's installation parameters, the rotation angle, and the perception angle of each pixel in the video frame, and converts the live video into multiple frames of images.

[0044] Among them, Figure 2 As shown in the figure, the direction pointed by the central observation line (main optical axis) of the image acquisition device is the observation center direction; the installation angle is the angle (counterclockwise angle) between the central observation line of the image acquisition device and the specified direction (due north direction) when the image acquisition device is installed and the rotation angle is 0, and the observation center direction of the image acquisition device is the initial direction; the rotation angle is the angle between the observation center direction of the image acquisition device and the initial direction; the perception angle is the angle (counterclockwise angle) between the line connecting the observation point of the image acquisition device in the on-site picture and the center point (focus) of the image acquisition device and the central observation line of the image acquisition device.

[0045] At the site of the power infrastructure project, a large number of image acquisition devices will be deployed during the construction phase of the power infrastructure project. Each group of two image acquisition devices is composed of two image acquisition devices. The coordinate positions and installation angles of the two image acquisition devices in each group are different, but the site pictures collected by the two image acquisition devices have overlapping observation areas. Combining the three-dimensional coordinate information of the power transmission and transformation project of the power infrastructure project can form a three-dimensional scene of the power transmission and transformation project and the distribution of image acquisition devices.

[0046] Step 3: Input any one of the two on-site pictures containing the overlapping observation area into the recognition model based on the deep neural network to identify all target objects in the overlapping observation area, including people, machines, materials and buildings.

[0047] The recognition model based on deep neural network needs to be trained using a training set. Specifically, it is necessary to collect pictures of any infrastructure site including people, machines, materials, or buildings, and mark the people, machines, materials, or buildings in the pictures as training sets, and build a neural network on a large data set. This neural network is a general visual system neural network.

[0048] This universal visual system neural network processes the on-site images sent back by the image acquisition device at the infrastructure site. For example, this universal visual system neural network processes the real-time video stream sent back by the camera at the infrastructure site, and uses the video stream to identify all personnel, machinery, equipment and other objects in the three-dimensional scene of the power transmission and transformation project through pure vision.

[0049] Step 4: based on the installation parameters, rotation angle, overlapping observation area and the perception angle of each pixel point in the overlapping observation area of ​​each set of image acquisition devices, a triangle formed by two image acquisition devices in each set of image acquisition devices and a common observation point in the overlapping observation area is obtained;

[0050] Specifically, the distance between two image acquisition devices in each group of image acquisition devices is calculated through the coordinate position of each group of image acquisition devices, and the installation angle, rotation angle and perception angle of the two image acquisition devices to the same observation point in the overlapping observation area are combined to obtain the triangle formed by the two image acquisition devices and the same observation point in the overlapping observation area. Step 5: The distance from the two image acquisition devices to the same observation point is obtained by analyzing the triangle, and the coordinates and sizes of all target objects in the overlapping observation area are obtained in combination with all the target objects identified in the overlapping observation area, so as to construct a three-dimensional model of the construction site.

[0051] like Figure 3As shown in FIG. 1 , it is a schematic diagram of camera triangulation (simplified to a horizontal plane). In the figure, there is a group of image acquisition devices (i.e., camera 1 and camera 2). Assume that the coordinate positions of two image acquisition devices in a group of image acquisition devices are A (x1, y1) and B (x2, y2), respectively. A certain pixel point in the overlapping observation area of ​​the group of image acquisition devices is C (i.e., any common observation point on the object within the field of view of the image acquisition device). The triangle formed by the group of image acquisition devices and the pixel point C is △ABC:

[0052] (1) According to the coordinate positions of the two image acquisition devices, A(x1, y1) and B(x2, y2), the distance formula Calculate the distance LAB=|AB| between the two image acquisition devices;

[0053] (2) Calculating the observation angles of the two image acquisition devices based on the observation angles and rotation angles of the two image acquisition devices; the observation angle is the angle (counterclockwise angle) between the observation center direction of the image acquisition device and the specified direction (due north direction), and the observation angle is the sum of the installation angle and the rotation angle;

[0054] (3) Based on the observation angle and the perception angle, calculate the angles of the two base angles of the triangle;

[0055] (4) The distances from the two image acquisition devices to the same observation point C can be obtained by analyzing a triangle with a known base length LAB and two base angles;

[0056] (5) Combining the coordinate positions of the two image acquisition devices, A and B respectively, the coordinates of pixel point C are obtained.

[0057] According to the coordinates of all pixel points, combined with all the target objects in the identified overlapping observation area, the coordinates and sizes of all the target objects in the overlapping observation area are obtained, thereby constructing a three-dimensional model of the construction site.

[0058] In the actual three-dimensional case, the actual triangle is the plane determined by AB and the common observation point C rather than the horizontal plane. The coordinates of any common observation point in the three-dimensional environment are analyzed by calculating the elevation information in the longitude and latitude coordinates and the included angle in the vertical direction. Because C is any point within the field of view of the two cameras on the object, the coordinates of any boundary point of the observed object can be obtained, thereby obtaining the size of the observed object.

[0059] That is, the distance between the two cameras can be calculated by the precise coordinate position obtained by the camera. According to the installation angle and observation angle of the two cameras, when the two cameras observe the same point, the angle between the line between the camera and the observation point and the line between the two cameras is obtained to construct a triangle. By analyzing the triangle, the position of the camera to this point can be calculated. The distance of all points within the observable range of the two cameras can be obtained through triangulation. Thus, the coordinates and size of each object within the observation range are constructed. Combined with the identified object category, a 1:1 high-precision model with the actual object is automatically constructed.

[0060] Step 6: By comparing the engineering site model obtained by the image acquisition device with the high-precision three-dimensional model established by the user in the initial design stage, the actual progress of the power infrastructure project is analyzed. Correction analysis is also performed based on the personnel and machinery conditions on site.

[0061] The present invention does not need to be based on a completed power infrastructure project video surveillance image as a learning sample, and does not judge the progress and quality by the difference between the current infrastructure project and the infrastructure project being learned. Instead, a universal visual system neural network is used to identify various types of personnel, tools, and buildings on site, and the progress of the infrastructure project is determined by matching them with the infrastructure GIM three-dimensional model constructed in the early stage. Compared with the traditional method, the method of the present invention eliminates the tedious process of collecting and acquiring all the video surveillance images of an electric power infrastructure project to train the progress monitoring model. At the same time, because the infrastructure project is not a simple copy of a template, when a new infrastructure project is built or the infrastructure project is different from the sample, the traditional method will fail or the cost will be incalculable. This case is more extensive and has lower cost by comparing the CIM model.
