Embodiment 1
[0038] refer to figure 1 , which shows a flow chart of an identification method for an aircraft structural profile according to an embodiment of the present invention. This embodiment may specifically include the following steps:
[0039] In step 101, the coordinates of discrete points on the part cross-section boundary of the current profile and the topological connection relationship between the discrete points are acquired.
[0040] The part section of the aircraft structural profile is composed of closed polygons, and the polygon is composed of multiple lines connected by nodes, so several nodes can be selected as discrete points, and then a coordinate system can be established in the part section to obtain the described The coordinates of the discrete points.
[0041] It should be noted that a discrete point is an isolated point set, unlike an interval, which is continuous at every point, and like an integer set, there is a little distance between each element of it. Th...
Embodiment 2
[0058] On the basis of the above embodiments, this embodiment continues to discuss the method for identifying aircraft structural profiles.
[0059] refer to figure 2 , which shows a flow chart of an identification method for an aircraft structural profile according to an embodiment of the present invention. This embodiment may specifically include the following steps:
[0060] In step 201, a profile library is established, and profile template information is stored in the profile library.
[0061] In this embodiment, a profile library with profile template information is first established, and profile template information corresponding to profile templates with different profile types is stored in the profile library, which can be used for type matching in subsequent step 207 and feature matching in step 208, thereby Realize the type identification and feature parameter extraction of the current profile.
[0062] The profile template information includes profile type of th...
Embodiment 3
[0108] On the basis of the above embodiments, this embodiment also discloses an identification device for aircraft structural profiles.
[0109] refer to Figure 8 , shows a structural block diagram of an identification device for aircraft structural profiles in an embodiment of the present invention. This embodiment may specifically include: a coordinate acquisition module 801, a centerline extraction module 802, a type matching module 803, a feature matching module 804, and an output module 805 ,in:
[0110] The coordinate acquiring module 801 is configured to acquire the coordinates of discrete points on the part section boundary of the current profile and the topological connection relationship between the discrete points.
[0111] The centerline extraction module 802 is configured to extract the centerline information of the current profile according to the coordinates of the discrete points and the topological connection relationship between the discrete points. In thi...
