Skeleton extraction and feature recognition method for plane traffic space of building

Abstract

The invention discloses a skeleton extraction and feature recognition method for a building plane traffic space, wherein the method comprises the steps: firstly drawing the contour of the building plane traffic space through a polyline, and marking an emergency exit; using a scanning line algorithm to calculate and obtain the division areas of the Thiessen polygon corresponding to the polylines; checking the Thiessen polygon one by one, deleting the Thiessen polygon if the line is located outside the plane contour, checking the dashed line of the Thiessen polygon one by one, and deleting the dashed line if one end of the dashed line is located on the plane contour; then, calculating the price of each node on the dotted line, representing the end corridor as a one-price node, and extending the end point until the end point intersects with the plane contour, the dotted line being a skeleton diagram corresponding to the plane contour; and extracting recognition features on the skeleton drawing. According to the method, the skeleton and the features of the building plane traffic space are automatically identified by means of computational graphics, the feature result is accurate and rapid, and mistakes and omissions caused by manual judgment are avoided.

Description

technical field [0001] The invention relates to the technical field of architectural design, in particular to a skeleton extraction and feature recognition method of a building plane traffic space. Background technique [0002] The traffic space in the building plan is the link connecting the functional rooms of each part, and its characteristics and properties have a key influence on the design of the building plan. The traffic space acts as a "trunk" in the building plan, and the functional rooms are the "branches" growing on the "trunk". [0003] In the process of architectural plan design, there are technically special adjacency requirements for some specific functional rooms. For example, in the plan design of the canteen, the space corresponding to the storage, cleaning, processing, and cooking of fresh ingredients not only has its own specific order requirements, but also has a room corresponding to the cleaning of recycled dishes and the sorting and recycling of kit...

Problems solved by technology

In addition to the adjacency requirements, in the fire protection design of buildings, there are also different regulations on the distance from different positions of the aisle (bag-shaped aisle and non-bag-shaped aisle) to the safety exit. .P285) defines the pocket walkway as "a walkway with only one evacuation direction, so the rooms located on both sides of the pocket walkway are not conducive to the safe evacuation of personnel". The current general design method can only distinguish the pocket walkway manually. aisle, and further design

For the above problems, for more complex building planes, if all rely on manual inspection and judgment, the workload will be huge, and the design quality of the building plane depends on the quality and skill level of the designers, and it is easy to miss everything.
