Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0031] Reference Figure 1 As shown, the present invention discloses an intelligent inspection and report generation method based on panoramic data, comprising the following steps:

[0032] Virtual data entry step: input the floor plan and BIM data model of the engineering design into the workbench;

[0033] Coordinate matching step: Establish a plane rectangular coordinate system based on the plan, and match the coordinate system with the BIM data model;

[0034] Observation point selection steps: The staff selects the observation point in the plan and determines the actual building point corresponding to the observation point;

[0035] Real-scene data acquisition steps: The inspectors wear safety helmets with camera functions, take images of actual building locations, obtain real-scene data and store them in the cloud database;

[0036] Observation point comparison steps: The staff selects the observation point in the plan, and the workbench retrieves the BIM data model position and real-scene data corresponding to the observation point and compares them to obtain the comparison result;

[0037] Report generation steps: Generate an inspection report based on the comparison results and output it.

[0038] Furthermore, in the coordinate matching step, coordinate system matching includes converting plane rectangular coordinates into BIM model coordinates using a coordinate conversion matrix.

[0039] Furthermore, the coordinate system conversion is specifically: performing three types of transformations between the plane rectangular coordinate system and the BIM model coordinate system: translation, rotation and scaling. The conversion matrix can be expressed as:

[0040]

[0041] Where (m',n') is the BIM model coordinate, k is the scaling factor, is the rotation matrix, θ is the rotation angle, and (p,q) is the displacement.

[0042] Furthermore, in the observation point selection step, the observation points are selected as points of important units that can cover the surveying and mapping area.

[0043] Specifically, when selecting observation points, try to choose those that are stable and not easily disturbed by external factors. In addition, the location of the observation point should be as far away as possible from factors that may cause interference, such as high-voltage cables, water pipes, etc.

[0044] Further, see Figure 2 As shown in the figure, in the model building step, in the observation point selection step, locating the actual building point includes:

[0045] S1. Identify all entity units in the BIM model, obtain the outer rectangular frames of all entity units, obtain the vertex coordinates of each outer rectangular frame, and obtain the center point coordinates based on the vertex coordinates of the outer rectangular frame;

[0046] S2, calculating the distance between the selected coordinates of the BIM model and the coordinates of the center point of each outer rectangular frame as the first distance;

[0047] S3, selecting the minimum value among all the first distances as the unit distance, and determining the position distance between the selected coordinates and the entity unit and the first outer bounding rectangular frame;

[0048] S4, calculating the distance between all planes of the first outer rectangular frame and the selected coordinates as the second distance;

[0049] S5. Select the shortest second distance as the plane distance, determine the second plane, and finally determine the actual building point.

[0050] Further, a vertical projection of the selected coordinates on the second plane is determined, the actual building point position is determined based on the projection point position, and the building point position is sent to a cloud storage unit.

[0051] Furthermore, the safety helmet receives the observation points in the cloud storage unit, and the inspectors go to inspect. When the safety helmet detects that the inspectors have arrived at the corresponding points, the camera function is automatically turned on to take pictures of the corresponding images of the observation points.

[0052] Furthermore, a memory card and a wireless communication unit are arranged inside the safety helmet;

[0053] When a wireless signal is detected, the wireless communication unit is controlled to transmit data;

[0054] When the wireless signal strength is not enough for stable transmission, the memory card stores the video data.

[0055] Furthermore, when the video data is stored in a memory card, the inspection personnel need to use an internet-enabled terminal to read the contents of the memory card and upload it to a cloud storage unit.

[0056] Furthermore, the observation point comparison step includes algorithm comparison and manual comparison.

[0057] Specifically, the algorithm comparison includes capturing image data in the video and image data of the BIM model, respectively extracting image contours and performing comparative detection.

[0058] Furthermore, in the report generation step, the generated report is stored in a cloud storage unit according to the date to facilitate subsequent verification.
