DETAILED DESCRIPTION

[0017] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. 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 making creative efforts are within the scope of protection of the present invention.

[0018] refer to Figures 1 to 3 , a method for automatically reviewing building setbacks, comprising: Receive drawings for review uploaded by applicants; Detecting whether the drawing to be reviewed is assigned values according to preset layer attribute requirements, wherein the layer attribute requirements include building outlines and control lines; Calculate the building setback distance of the drawing to be reviewed based on the building outline and control line; Calculate the required minimum building setback distance range according to the preset specification requirements; Comparing the building setback distance of the drawing to be reviewed with the minimum building setback distance range required by the specification, and if the setback distance of the drawing to be reviewed is within the minimum building setback distance range required by the specification, then the result is judged to be in compliance; otherwise, the result is judged to be non-compliant; If the judgment result shows that there is any situation that does not meet the requirements, a problem list will be output. If the judgment result is all in compliance, an audit qualification report will be output.

[0019] In this embodiment, through the automated process, the drawings to be reviewed can be quickly received, detected and processed, greatly shortening the time required for manual review. The automated calculation of building setback distances and comparison operations reduces the steps of manual operation and speeds up the review. The detection is based on the preset layer attribute requirements to ensure the consistency and accuracy of the drawing information. Through precise calculation and comparison, calculation errors or judgment deviations that may occur in manual review are avoided. The automated review process is clear and each step has clear judgment criteria and output results. When the drawings do not meet the requirements, a detailed list of problems is output so that the applicant can clearly understand the specific location and reasons for non-compliance with the specifications. Automated review reduces dependence on manual reviewers and reduces labor costs. It can run uninterruptedly for 24 hours, improves work efficiency, and reduces the working time and number of personnel required for manual review.

[0020] Preferably, the calculating of the building setback distance of the drawing to be reviewed based on the building outline and the control line specifically includes: Determine the line type of the building outline and the control line, wherein the control line includes the land boundary line, blue line, green line, and road edge line; According to the line types of the building outline and the control line, the shortest distance between the building outline and the control line is calculated using the point-to-straight line distance formula, the point-to-arc distance formula, the point-to-complex curve distance formula or the point-to-point distance formula.

[0021] In this embodiment, by determining the line type (e.g., straight line, arc, complex curve, or point) between the building outline and the control line, the technical solution can adopt corresponding distance calculation formulas (point-to-straight line distance formula, point-to-arc distance formula, point-to-complex curve distance formula, or point-to-point distance formula) for different line types. This classification processing method can ensure calculation accuracy and avoid calculation errors caused by line type mismatch. Through the automated calculation process, the technical solution can quickly determine the shortest distance between the building outline and the control line, thereby avoiding the tedious and time-consuming traditional manual calculation methods. This not only saves a large amount of human resources, but also accelerates the approval process and improves work efficiency. By automating the distance calculation process between the building outline and the control line, it can achieve rapid and accurate review of architectural drawings, which helps promote the intelligent development of urban planning and management. By accurately calculating the distance between the building outline and the control line, the technical solution can provide more scientific and objective data support for urban planning and management, which helps planning departments better understand urban spatial layout, ensure the compliance of construction projects, and thus improve the overall level of urban planning and management. In addition, the land boundary and building outline must exist, and the road edge lines, green lines, and blue lines are drawn according to the surrounding conditions of the land. If the applicant fails to assign attribute values according to the attribute content requirements, the inspection will fail.

[0022] It should be noted that when the building outline and the control line are both straight segments, the coordinate points of each line segment of the building outline are traversed to calculate the distance from each coordinate point of the building outline to the control line. , the endpoints of the control line are and , solve the shortest distance from the building outline point to the control line Formula 1: ; When one of the building outline and the control line is a straight line segment and the other is a regular curve (circle, ellipse arc segment), the center point of the circle is known. , arc endpoint and , with a radius of r, calculate the distance from the center of the circle to the line segment , its calculation formula is the same as formula 1, the formula Just change it to the center point coordinates, then at this time, the shortest distance Formula 2: ; When the building outline and the control line segments are regular curves, the shortest distance The distance between the center of the circle, the distance between the endpoints, and the distance from the endpoint to the arc are expressed as Formula 3:

[0023] Where d is the distance between the two circle centers, and the calculation formula between the two points is the same as Formula 3; and are the radii of the two arcs; Indicates the distance from the endpoint to the arc. Indicates the end-to-end distance; When the building outline or control line is a complex curve, due to the irregular complex curve, it is impossible to accurately define the curve parameter equation. Therefore, the present invention decomposes the curve into multiple lines and extracts n sampling points on the curve at a certain density. If one of the building outline or land boundary line is a complex curve and the other is a straight line segment, the sampling points of the curve segment are traversed and the distance between all sampling points and the straight line segment is calculated using Formula 1 until the shortest distance to the straight line segment is found. If both the building outline and the control line are curves, their sampling points are respectively 、 , then the shortest distance between the sampling points of the two curves is Formula 4: .

[0024] Preferably, the determining of the line type of the building outline and the control line specifically includes: Determine whether the building outline intersects with the control line. If so, the shortest distance is zero; Determine whether the building outline and control line segments are straight lines, regular curves or irregular complex curves.

[0025] In this embodiment, it is first determined whether the building outline and the control line intersect. This is a fast and intuitive judgment process. If they intersect, the shortest distance is directly concluded to be zero without further complex calculations, thereby greatly improving the processing efficiency. The line segments of the building outline and the control line are divided into three types: straight line segments, regular curves, and irregular complex curves. This classification method helps to select a suitable distance calculation formula for calculation, avoiding calculation errors caused by misjudgment of line types. At the same time, different processing strategies can be adopted for different types of line types. For example, for straight line segments, the point-to-straight line distance formula can be directly used, for regular curves, parametric equations can be used for calculation, and for Irregular and complex curves may require numerical methods or approximation algorithms for calculation; by judging the line type, the technical solution can select the appropriate calculation method based on the actual situation of the building outline and control line. This flexibility enables the algorithm to adapt to building outlines and control lines of different complexities and shapes, thereby improving the algorithm's applicability and practicality; automatically reading drawing information, judging line types, calculating distances and outputting results, which greatly reduces the degree of manual intervention and improves processing speed and accuracy; by automating the distance calculation problem between building outlines and control lines, it can speed up approval, improve approval quality, and provide more scientific and objective data support for urban planning management.

[0026] Preferably, in the process of calculating the building setback distance of the drawing to be reviewed, when the building outline and the control line are both complex curves, the curve is decomposed into multiple line segments, and sampling points are extracted on the curve at a certain density. The distance formula from the point to the straight line is used to calculate the distance between all sampling points and the straight line segment or another curve segment to determine the shortest distance.

[0027] In this embodiment, decomposing a complex curve into polylines and extracting sampling points at a certain density along the curve ensures that subtle changes in the curve are captured during the calculation process. By calculating the distance from each sampling point to other line segments or curve segments, the shortest distance can be more accurately determined, thereby improving the accuracy of the calculation. This technical solution can handle complex curves, demonstrating the algorithm's strong adaptability in processing irregular shapes and complex geometric figures. This adaptability enables the algorithm to be widely applied to various types of building outlines and control lines, improving the algorithm's versatility and practicality. Although decomposing a curve into polylines and extracting sampling points increases the complexity of the calculation, by properly setting the density and number of sampling points, the calculation efficiency can be optimized while ensuring accuracy. In addition, using the point-to-line distance formula for calculation is generally more efficient than directly processing complex curves. The curve decomposition, sampling point extraction, and distance calculation can be completed automatically, greatly improving processing speed and accuracy and reducing the degree of manual intervention.
