The construction area needs to be inspected frequently, potential safety hazards are inspected timely, the construction progress is tracked, and the construction can be smoothly carried out according to the expected planning. As shown in fig. 1, in the related art, the routing path of the inspection machine is generally formed by a constructor simply set up in the inspection machine based on a third party map, and such a scheme can easily generate the condition that the place to be inspected is missed to be inspected or the place to be inspected is not mistakenly inspected when the inspection machine is inspecting, so that the inspection data collected by the inspection machine is not complete and accurate enough, and finally the accurate construction condition of the target construction area cannot be obtained.

Therefore, the embodiment of the invention provides a construction inspection method, which is characterized in that BIM (Building Information Modeling, building information model) inspection model data are sent to an inspection machine by a server 1, wherein the BIM inspection model data comprise a road line and an inspection project. As shown in fig. 2, a routing inspection anchor point is further disposed on the routing path, where the routing inspection anchor point is used to enable the routing inspection machine 2 to stay in a check point area of the target construction area for a period of time, and continuously collect routing inspection data of the check point area, so that the occurrence of missing inspection or false inspection of the routing inspection machine can be reduced. The server 1 can be more accurate and complete after receiving the inspection data collected by the inspection machine 2, so that the construction condition of the target construction area can be more accurately analyzed and determined.

The construction inspection method provided by the embodiment is applied to a server 1 of a construction inspection system, as shown in fig. 3, the construction inspection system further comprises an inspection machine 2, and the server 1 is in communication connection with the inspection machine 2. The inspection machine 2 is provided with a plurality of information collecting probes, such as a camera, an air quality detection sensor, a noise detection sensor and the like. The inspection data acquisition can be performed aiming at inspection projects such as construction progress, air quality, noise data, environmental sanitation conditions and the like. The server 1 may be a cloud server 1.

Further, the construction inspection system can further comprise an upper computer 3, BIM design software is loaded on the upper computer 3, and a target construction area can be accurately displayed in a three-dimensional model mode.

The construction inspection method in this embodiment specifically includes the following steps performed by the server 1, as shown in fig. 4:

step 101, BIM inspection model data of a target construction area are obtained, wherein the BIM inspection model data comprise a road line and inspection items.

Wherein the inspection items may include at least one of construction progress, air quality, noise data, and sanitation conditions. Meanwhile, a routing inspection anchor point is arranged on the travelling path, and the routing inspection anchor point can enable the routing inspection machine 2 to stay for a long enough time when moving to a check point area of a target construction area so as to continuously collect routing inspection data of the check point area, so that the condition of missing inspection of the routing inspection machine can be reduced. If the target construction area is a floor in a building, the inspection anchor point can comprise areas such as a corridor, an elevator, doors and windows, a strong electric well, a weak electric well and the like.

BIM inspection model data can be obtained through setting in a BIM model corresponding to a target construction area by the upper computer 3. Specifically, a floor plan of the target construction area is developed in the BIM model, and then the route of the inspection machine 2 and the inspection items are planned in the floor plan, so that BIM inspection model data is generated.

Step 102, transmitting BIM inspection model data to the inspection machine 2, so that the inspection machine 2 moves in the target construction area according to the road path, and collecting inspection data of the target construction area according to the inspection project.

The server 1 and the inspection machine 2 may be connected by wireless communication. The server 1 compresses the BIM inspection model data and then sends the compressed BIM inspection model data to the inspection machine 2 so as to improve the data transmission rate. The inspection machine 2 receives and stores BIM inspection model data, then automatically moves along a path in the BIM inspection model data, and shoots a target construction area according to a set inspection project in the moving process to obtain image and/or video data, wherein the image and video data are inspection data.

Step 103, receiving inspection data from the inspection machine 2.

The inspection data sent by the inspection machine 2 may be continuously received, or the inspection data may be received at intervals.

And 104, determining the current construction condition of the target construction area according to the inspection data.

The server 1 is provided with an image recognition model, specifically, the image recognition model is used for recognizing and extracting information in the inspection data to obtain recognition information, and the recognition information can comprise construction completion degree, environmental sanitation degree and construction potential safety hazard; and then determining the current construction condition of the target construction area according to the identification information.

In the construction inspection method of the embodiment, the routing path of the inspection machine 2 can be accurately planned through BIM design software, so that the inspection machine 2 automatically inspects according to the routing path, and the inspection data with enough quantity stays and collects at the inspection anchor point, thereby reducing the conditions of missing inspection and false inspection. The server 1 can obtain accurate and complete inspection data of the inspection machine 2 in real time, so that the current construction condition of the target construction area can be accurately obtained through analysis, and the inspection efficiency of the target construction area is improved.

In this embodiment, the processing procedure of the image recognition model may be as follows:

1) And carrying out gray scale processing on the original image in the inspection data to obtain a gray scale image.

The method comprises the following steps: the channel values of three channels of each image R, G, B are subjected to weighted average operation, and the operation result is assigned as the gray value of the point.

2) And carrying out sequential filtering processing on the gray scale image to remove noise in the gray scale image.

3) Identifying boundary information in the gray scale map by an edge operator and determining an ROI (Region of Interest ) in the image; in the process of determining the ROI, setting whether the ROI area is in the boundary or out of the boundary according to the identified actual object; the edge operator may be any one of sobel (sobel operator), roberts (Roberts operator), prewitt (pu Li Weite operator), and Canny (edge detection operator).

4) And according to the boundary information in the gray level diagram, a corresponding ROI area is cut out from the original image along the boundary.

5) Scaling the cut ROI area to a fixed size, and then pasting the ROI area into a white blank bottom plate picture with a preset size.

The processing steps can effectively avoid the influence of the background on the image recognition, are beneficial to improving the accuracy and the efficiency of the image recognition, and the image processing method is simpler and has smaller calculated amount. The inspection data collected by the inspection machine can be accurately identified, and the construction conditions such as the construction progress, the construction environmental sanitation degree, the existence of construction potential safety hazards and the like of the target construction area can be accurately identified and judged.

For example, when the inspection machine 2 inspects the ventilation opening of the corridor, the inspection machine is an inspection anchor point, images of the inspection anchor point are shot and uploaded to the server 1, the image recognition model recognizes whether the inspection anchor point is provided with a ventilation window, and if the recognition result is that the ventilation window is not provided, the inspection machine is not matched with the design in the BIM model, and the construction condition is not compliant.

The image recognition model of the embodiment includes a convolutional neural network, which adopts a SimpleCNN (Simple Convolutional Neural Network ) algorithm improved by knowledge distillation, and guides the SimpleCNN algorithm which is not completely trained to train through a VGG (Visual Geometry Group ) network which is already trained, so as to obtain a lightweight neural network model. The training of the simpleCNN network which is not completely trained is guided by the VGG network (which can be particularly a VGG19 network), so that the overfitting of the simpleCNN network can be avoided, the convergence of the simpleCNN network faces the VGG network, the simpleCNN network has the recognition capability of the VGG network, and the light weight of the simpleCNN network is ensured.

Firstly, training a teacher neural network (VGG network in the embodiment) by utilizing a data set, so that the teacher neural network fully learns the knowledge contained in the data; then, when training the student neural network (SimpleCNN in this embodiment) by using the data set, the learned knowledge in the teacher neural network is extracted by a distillation method to guide the training of the student neural network, so that the student neural network is equivalent to acquiring prior information about the data set from the teacher neural network.

In knowledge distillation, the teacher neural network is trained on the data set in advance, and then the training process of the student neural network is guided by the knowledge learned by the teacher neural network, so that the accuracy of the student neural network is improved.

Further, in order to improve the accuracy of the image recognition model, training optimization is required. And taking the image data set as input, distilling the simpleCNN network through the VGG19 network, obtaining different loss functions through setting different distillation temperatures, then carrying out back propagation, and then storing model parameters to obtain the neural network model for identifying the image. The method comprises the following specific steps:

1. The pixel mean of each image in the dataset is calculated and each image is adjusted to 224 x 224 pixels.

2. And subtracting the obtained pixel mean value from the pixel value of each channel of the adjusted image to obtain image processing data.

3. Constructing a knowledge distillation module, wherein the knowledge distillation module consists of a VGG19 network with trained parameters and an untrained simpleCNN network, and the simpleCNN network is guided to train through the VGG19 network; when training simpleCNN, the images are input in batches, and 3D convolution, batch standardization, maximum pooling, reLU (Rectified Linear Activation Function, correction of linear activation function) and 2DLSTM (2D Long Short-Term Memory) operation are carried out on each batch of images to obtain characteristic images.

4. And flattening the characteristic image in a multi-channel manner, removing unnecessary neurons through a Dropout (inactivation) layer, linearly mapping to deepen network depth, and finally classifying and outputting through Softmax (normalized exponential function) to obtain a loss function and characteristic data.

5. And replacing the loss function of the whole network with knowledge distillation of linear weights of each soft target and each hard target, carrying out back propagation on the loss function, and continuously carrying out parameter correction to obtain deep features.

And finally, inputting the verification set image into a neural network, comparing the obtained result with an image label, calculating an error, performing reverse calculation according to the error, updating model parameters, and storing the model parameters to obtain a neural network model for identifying the image.

In one embodiment, the travel route is a circular route at the patrol anchor. Therefore, when the inspection machine 2 moves to the inspection anchor point, the inspection machine can rotate for a circle to carry out 360-degree panoramic shooting and information acquisition on the key area, obtain more specific inspection data of the key area and avoid missing inspection and false inspection.

In order to ensure that the inspection machine 2 can stay for a period of time and rotate when moving to the inspection anchor point, an electronic fence can be arranged at the inspection anchor point, an annular route is defined through the electronic fence, a module which is induced by the electronic fence is arranged on the inspection machine 2, and the electronic fence can limit the inspection machine 2 to move in a key area.

In an embodiment, the electronic fence may also be a virtual electronic fence designed in the BIM model, and the virtual electronic fence defines a circular route of the important inspection area on the path route.

In an embodiment, as shown in fig. 5, the construction inspection method may further specifically include the following steps:

step 201, BIM inspection model data of a target construction area is obtained.

The BIM inspection model data comprise a road path, inspection items and standard data corresponding to the inspection items; the standard data can comprise a standard value of an air pollution index, a standard value of noise decibels and a standard value of construction progress; the routing is provided with the routing anchor point, and the routing anchor point can enable the routing machine 2 to stay for a period of time enough when moving to the check point area of the target construction area so as to continuously collect routing data of the check point area, so that the condition of missing inspection of the routing machine can be reduced.

Step 202, determining whether the BIM inspection model data is correct.

Specifically, firstly, BIM inspection model data and historical BIM inspection model data are compared to obtain a comparison result; and then judging whether BIM inspection model data are correct or not according to the comparison result.

For example, the route in the BIM inspection model data is compared with the route in the historical BIM inspection model data to determine whether the two are consistent or whether the similarity is within a set range. If yes, judging that the path line in the BIM inspection model data is correct. Meanwhile, the inspection items in the BIM inspection model data can be compared with the inspection items in the historical BIM inspection model data to judge whether the two inspection items are consistent or whether the similarity is within a set range; if yes, judging that the inspection items in the BIM inspection model data are correct.

And 203, if not, correcting the BIM inspection model data.

Through the steps, BIM inspection model data transmitted to the inspection machine 2 can be ensured to be correct, and the inspection machine 2 is prevented from inspecting according to a set travelling path. When BIM inspection model data are correct, the BIM inspection model data are directly sent to the inspection machine 2, when errors exist, the BIM inspection model data are corrected, and then the corrected correct BIM inspection model data are sent to the inspection machine 2.

Step 204, transmitting the correct BIM inspection model data to the inspection machine 2, so that the inspection machine 2 moves in the target construction area according to the road path, and collects the inspection data of the target construction area according to the inspection project.

Step 205 receives inspection data from inspection machine 2.

Specifically, the inspection data transmitted by the inspection machine 2 may be received by way of wireless communication. The wireless communication means may employ the following networks or techniques including, but not limited to: cellular networks (e.g., 3G networks, 4G networks, 5G networks, etc.), WLAN wireless local area networks, bluetooth, RFID (radio frequency identification).

The road path is a circular path at the inspection anchor point. Therefore, when the inspection machine 2 moves to the inspection anchor point, the inspection machine can rotate for a circle to carry out 360-degree panoramic shooting and information acquisition on the key area, obtain more specific inspection data of the key area and avoid missing inspection and false inspection.

And 206, identifying and extracting information in the inspection data through the image identification model to obtain identification information.

The identification information can include information such as construction completion, environmental sanitation, construction safety hazards and the like. In the embodiment, the image recognition model can adopt a convolutional neural network, and can accurately recognize the characteristics in the image and the video after multiple training optimization.

Step 207, comparing the identification information with the standard data to obtain a comparison result.

The comparison result may be a magnitude relation between the collected value of the inspection item in the identification information and the standard data value.

And step 208, determining the current construction condition of the target construction area according to the comparison result.

For example, comparing the picture of the construction condition at the inspection anchor point shot by the inspection machine 2 with the design in the corresponding BIM model, judging whether the construction condition of the inspection anchor point meets the design requirement in the BIM model, and if so, judging that the construction condition at the inspection anchor point is compliant; if the construction conditions are not in conformity with the inspection anchor points, the construction conditions at the inspection anchor points are judged to be not in compliance.

For another example, the air pollution index collected by the inspection machine 2 is a, the air pollution index standard value set in the server 1 is a, and if a is less than a, the air pollution at the inspection anchor point is judged to be out of standard; if a is more than or equal to A, judging that the air quality at the inspection anchor point reaches the standard. Assuming that the noise decibel number collected by the inspection machine 2 is B, the noise decibel number standard value set in the server 1 is B, and if B is less than B, judging that the noise at the inspection anchor point is compliant; if B is more than or equal to B, the noise at the inspection anchor point is judged to exceed the standard.

Step 209, if it is determined that the construction condition is not compliant, an alarm message is sent to the management unit.

The alert information includes category and location information for non-compliant inspection items. Specifically, alarm information can be sent to a management unit through modes such as APP message pushing or short messages, and the management unit is reminded to carry out rectification on places and projects which are not in compliance in a construction area.

Step 210, acquiring a patrol data set of the patrol machine, and storing the patrol data set and the BIM patrol model data as historical data.

On one hand, the historical data can be used as a training sample of the image recognition model so as to further improve the accuracy of the image recognition model. On the other hand, the historical data can facilitate the data retrieval of each inspection at the later time, and the traceability of the construction project data is improved.

In the construction inspection method of the present embodiment, inspection model data is sent to an inspection machine by a server 1, wherein the BIM inspection model data includes a route and an inspection item. As shown in fig. 2, a routing inspection anchor point is further disposed on the routing path, where the routing inspection anchor point is used to enable the routing inspection machine 2 to stay in a check point area of the target construction area for a period of time, and continuously collect routing inspection data of the check point area, so that the occurrence of missing inspection or false inspection of the routing inspection machine can be reduced. The server 1 can be more accurate and complete after receiving the inspection data collected by the inspection machine 2, so that the construction condition of the target construction area can be more accurately analyzed and determined.

According to which the profile data includes the course and corresponding standard data, e.g. emphasis of the target construction area

In an embodiment, after the inspection machine 2 reaches the target construction area, a self-inspection program is started first, the inspection machine 2 starts a pre-inspection program to scan the target construction area, and the coordinate system of the target construction area is matched with the coordinate system of the BIM inspection model, so that the inspection machine 2 can move in the target construction area according to the path in the BIM inspection model data.

Therefore, the processing process of the image recognition model is simpler, the calculated amount is smaller, and the accurate recognition of the inspection data collected by the inspection machine is facilitated.

S209, the server 1 determines the current construction status of the target construction area.
