s10, building an engineering construction model by the aid of a proctoring base on the basis of a construction design drawing, setting a plurality of observation points with fixed positions in the engineering construction model, and taking the observation points as datum points and the obtained image of the engineering construction model as a basic reference image. In the embodiment, the supervision terminal comprises an image acquisition terminal for shooting a construction site and a processing terminal for data processing.
In this embodiment, the processing terminal establishes a visual engineering construction model of the engineering construction building according to the size data on the construction design drawing, in this embodiment, the engineering construction model is a three-dimensional model, and the engineering construction model is reduced and presented in a certain proportion according to the effect of design construction. In the engineering construction model, the building details inside the model can be observed by moving the visual angle. It can be understood that the engineering construction model is observed like the VR technology.
A plurality of points are selected from the engineering construction model as observation points, the positions of the observation points are fixedly arranged relative to the engineering construction model, the observation points can be distributed inside and outside the engineering construction model, and each observation point comprises name information and position information relative to the engineering construction model. The observation point is used as a reference point, the visual angle of the observation point is adjusted, so that a plurality of images of the engineering construction model are acquired, and the plurality of images are integrated to obtain a basic reference image about the observation point. And recording relevant parameter information of the engineering construction model, wherein the parameter information comprises the size information of the building design and the mutual matching relationship between the building structures.
S20, acquiring sampling information of sampling observation points from a construction site, wherein the sampling observation points correspond to the observation points one to one, matching the sampling observation points with the observation points to obtain a position of a construction position on the construction site corresponding to an engineering construction model, and updating the inspection record of the observation points.
In the construction process, a plurality of sampling observation points are arranged on a construction site, the positions of the sampling observation points are also fixedly arranged relative to a construction building, the sampling observation points are used as reference points for proctoring personnel and an image acquisition end to observe the actual construction building, and the sampling observation points are in one-to-one correspondence with the observation points. The sampling observation point comprises the name and the position information of the sampling observation point and the position information of a construction site.
The image acquisition end scans the readable electronic identification at the sampling observation point on site, acquires the position information and the name information of the sampling observation point, integrates the position information and the name information into sampling information, and uploads the sampling information to the supervision end. The supervision terminal matches the sampling observation points with the observation points in the engineering construction model according to the sampling information, thereby confirming the area where the supervision personnel is located and the surrounding buildings, updating the inspection records of the corresponding observation points, and executing the following step S30. In other embodiments, the connection between the administrator and the readable electronic identifier may be a wireless connection, a bluetooth connection, or a GPRS connection.
And S30, acquiring the space distance between the actual shooting point and the sampling observation point, calculating the actual shooting point relative to the reference point in the engineering construction model, and acquiring the image of the engineering construction model at the reference point as an actual reference image.
Due to the fact that the site construction situation is complex, the preset sampling observation point may be shielded by construction facilities or the condition that a supervisor cannot conveniently check at the sampling observation point exists, so that the actual shooting point of the supervisor during the site construction is inconsistent with the preset sampling observation point, and the position relation between the actual shooting point and the sampling observation point needs to be calculated.
S31, referring to fig. 2, a three-dimensional space coordinate system is established with the sampling observation point as the origin of coordinates. The X axis and the Y axis of the three-dimensional space coordinate system are both horizontally arranged, and the Z axis of the three-dimensional space coordinate system is vertically arranged. Wherein, the X-axis extends to the construction position direction with the origin of coordinates, and the Y-axis is arranged perpendicular to the X-axis.
And S32, after scanning the readable electronic mark at the sampling observation point, the proctor establishes communication connection with the readable electronic mark for positioning the spatial position of the actual shooting point. The image acquisition end identifies the distance and the position direction of the actual shooting point relative to the readable electronic identifier, so that a space vector of the actual shooting point relative to the three-dimensional space coordinate system can be obtained, wherein the mode of the space vector is the distance of the actual shooting point relative to the readable electronic identifier, and the symbol of the space vector is the direction of the actual shooting point relative to the readable electronic identifier. The image acquisition end sends the space vector to the supervision end.
And S33, matching the actual shooting point with the engineering construction model. And after receiving the space vector, the processing terminal sets an observation point matched with the actual shooting point as a coordinate origin to establish a three-dimensional space coordinate system, wherein an X axis and a Y axis of the coordinate system are respectively arranged along the horizontal direction of the engineering construction model, and a Z axis of the coordinate system is arranged along the vertical direction of the engineering construction model.
And acquiring space vector data of the sampling observation point, and calculating the position in the three-dimensional space model which is relative to the observation point and is taken as the coordinate origin according to the space vector to be taken as the reference point of the actual shooting point.
And S34, acquiring an actual reference image. The reference point is used as the reference point, the visual angle of the reference point is adjusted, so that the images of the engineering construction models are obtained, the images are integrated to obtain an actual reference image about the reference point, and the actual reference image is sent to the image acquisition end.
And judging the position relation between the actual shooting point and the sampling observation point. When the actual shooting point is positioned at the sampling observation point, namely the modulus of the space vector is smaller than a preset vector threshold value, the transmitted actual reference image is the basic reference image; when the actual shooting point and the sampling observation point have deviation, the modulus of the space vector is larger than the preset vector threshold, the actual reference image sent by the processing terminal to the image acquisition end is an image of the engineering construction model acquired by taking the calculated reference point as the reference point, and the following step S40 is executed.
S40, obtaining a construction result image shot by the construction building at the actual shooting point by taking the actual reference image as a comparison, carrying out contour recognition on the construction result image to obtain contour data of the construction result image, carrying angle information, comparing the construction result image with the actual reference image, correcting the angle of the construction result image, and comparing the construction result image with a construction design drawing to obtain a construction quality evaluation value.
S41, referring to fig. 3, the processing terminal processes the actual reference image, extracts only the edge contour lines of the buildings in the actual reference image, and integrates the edge contour lines to form a reference contour map. And adjusting the actual shooting angle, taking the actual shooting point as the sampling circle center, taking the reference contour map as a reference, enabling the reference contour map to be approximately overlapped with the actual construction building, and shooting the construction building on site to obtain a construction result image. The construction result image includes appearance information of an actual construction building. It can be understood that the supervisor compares the structures in the actual construction building in sequence at the actual shooting point by taking the contour lines in the reference contour map as a comparison template, and shoots the most similar position to the contour lines in the construction building to obtain a construction result map, so that the angle and the image of the construction building shot at the actual shooting point are consistent with the angle and the image of the engineering construction model shot at the reference point, and the construction result map is compared and processed conveniently.
And S42, performing image processing on the construction result image. The processing terminal receives the construction result image collected by the image collecting terminal, firstly carries out image processing on the construction result image to obtain a construction result processing image, and the image processing comprises image gray processing, image edge sharpening processing and image denoising processing.
Specifically, when the construction result image is subjected to the gradation processing, a process of converting the color image into the gradation image is referred to as the gradation processing of the image. The color of each pixel in the color image is determined by R, G, B three components, and the preferred value of each component is 255, so that a pixel can have a range of 1658 thousands (255 x 255) of colors. The image gray processing is to make R, G, B components of a color image equal to form a gray image, and since R, G, B components are equal, the variation range of one pixel is reduced to 255, so that in the digital image processing, images in various formats are generally converted into gray images, so that the calculation amount of subsequent images is reduced.
The description of a grayscale image, like a color image, still reflects the distribution and characteristics of the chrominance and luminance levels, both globally and locally, of the entire image. The color construction result image is converted into a gray level image, the quality of the construction result image is improved, and the construction result image can display more details so as to be convenient for subsequent identification and analysis of the construction result image. In this embodiment, the grayscale processing method for the construction result image may be any one of a component method, a maximum value method, an average value method, and a weighted average value method, so as to obtain a grayscale image.
And carrying out sharpening on the gray-scale image after the gray-scale processing, wherein the sharpening is to reduce the blur in the image by enhancing high-frequency components, enhance the detail edge and contour of the image, enhance the gray-scale contrast and facilitate the identification and processing of the target in the later period.
In this embodiment, a common algorithm for image sharpening is called as an unsharp Mask USM sharpening enhancement algorithm (unsharp Mask algorithm), abbreviated as an USM sharpening algorithm, in the sharpening method, a gaussian blur is first performed on an original image to obtain a passivated blurred image, the passivated blurred image is subtracted from the original image to obtain a high-frequency partial image, the high-frequency partial image is multiplied by an amplification factor to obtain an amplified high-frequency partial image, and the amplified high-frequency partial image and the original image are finally superimposed to obtain a sharpened image, so that edge information in a gray image is clearer, and some fine interference details and noise in the gray image can be removed. Compared with the image sharpening result obtained by directly using a convolution sharpening operator, the USM sharpening algorithm is more real and credible.
The computational formula of the USM sharpening algorithm is expressed as follows:
sharpened image = original image + (original image-w gaussian blur)/(1-w);
wherein w represents a weight (0.1-0.9), and w is 0.6 as default; (1-w) represents an amplification factor.
