Problems solved by technology

[0004] However, the current map compiler does not have the function of batch importing CAD points. When the project has a large number of cameras that need to be marked and devices that need to be bound, it will take a lot of time and labor costs

Embodiment 1

[0030] A method of importing CAD drawing elements into a 3D map, such as Figure 7 As shown, the coordinate system of the CAD engineering drawing and the 3D map are the same, such as figure 1 Shown, the figure that several floors and camera are arranged in described CAD engineering drawing, the bottom of described camera corresponds to marking camera ID code; The information output in CAD engineering drawing is in the EXCEL table, as figure 2 As shown, all coordinate points are classified into floors, all coordinate points of each floor are obtained, and the points of each partition are aggregated, and the camera is associated with the camera ID code.

[0031] The invention realizes the import of the camera in the CAD engineering drawing into the three-dimensional map, and realizes the automatic labeling of the camera's point position, better displays the position of the camera on each floor in the three-dimensional map, improves the work efficiency, and has better practical...

Embodiment 2

[0033] This embodiment is optimized on the basis of Embodiment 1, marking the boundary points and floor numbers of each floor, such as image 3 , Figure 4 As shown, set points in half at the lower left corner and upper right corner of the boundary of each floor, and mark them with F n , as the boundary point; where n is the floor number.

[0034] Such as Figure 5 As shown, analyze the EXCEL table to get the name, coordinates and corresponding values ​​of each block in the CAD engineering drawing, where the dots whose names are letters represent the blocks of the camera; where the blocks whose names are text are the blocks identified.

[0035]Traverse and filter all point information in the EXCEL table, find the set of area identification points through the value; classify the value of the boundary point set again, classify the coordinate point information of the boundary point with the same value into one category, and classify the value Map with the point information set...

Embodiment 3

[0039] This embodiment is optimized on the basis of Embodiment 1 or 2. The CAD engineering drawing draws a camera pattern according to the actual position, and the camera ID code corresponding to the camera is marked under the pattern; the center of the number in the camera ID code is the same as The distance between the X and Y axes of the center point of the pattern shall not exceed 200.

[0040] Filter out the point information set nameList corresponding to the camera ID code, filter out the point information set pointList corresponding to the camera icon, traverse the pointList and use the coordinates as the coordinate information of the camera, compare the coordinate values ​​of each element in the nameList, and filter out the coordinate difference The point information less than or equal to 200, and the value of the filtered point information is used as the serial number information of the device, and put into a new object; after the traversal is completed, a new collecti...

Abstract

The invention discloses a method for importing CAD engineering drawing elements into a three-dimensional map. The coordinate systems of the CAD engineering drawing and the three-dimensional map are the same. The CAD engineering drawing is provided with pictures of several floors and cameras, and the bottom of the camera corresponds to Mark the camera ID code; output the information in the CAD drawing to the EXCEL table, classify all coordinate points into floors, obtain all coordinate points on each floor, and aggregate the points of each partition to combine the camera with Camera ID encoding association. The invention realizes batch importing of cameras in CAD engineering drawings into a three-dimensional map, and realizes automatic point position labeling of the cameras, more quickly and accurately displays the position of the cameras on each floor in the three-dimensional map, improves work efficiency, and has a higher Good practicality.

Description

technical field [0001] The invention belongs to the technical field of data conversion, and in particular relates to a method for importing CAD engineering drawing elements into a three-dimensional map. Background technique [0002] With the development of society, artificial intelligence plays a huge role in more and more fields and promotes the development of society. This scene is especially obvious in the field of security. In the field of security, the accuracy of the position of the camera on the map determines the speed of our response to emergency incidents. Therefore, in security engineering, the positioning of the camera in the middle of the map is a very important task. [0003] The existing map editing software is compatible with tile maps (Baidu, Gaode, Google, etc.), picture maps (hand-painted) or web three-dimensional maps (third-party), and can manually add camera points to the map and bind IP stream addresses If specified, the map relationship hierarchy ca...
