Abstract

The invention discloses a point location coordinate automatic measurement method based on a user coordinate system in a CATIA environment. The method comprises the following steps: step 1, establishing a point location positioning transformation super copy model in CATIA software; step 2, opening a to-be-tested point location model in CATIA software; step 3, selecting a user coordinate system and a to-be-tested point set P in the to-be-tested point position model in the CATIA software; and step 4, performing coordinate transformation on each to-be-measured point in the to-be-measured point set P selected in the step 3 from the user coordinate system to the system coordinate system by cyclically calling the point location positioning change super copy model in the step 1, and completing automatic point location coordinate measurement based on the user coordinate system in the CATIA environment. The invention solves the problems that the existing point location coordinate data is usually realized under a system coordinate system, and the point location measurement based on a user coordinate system usually needs to be manually measured under the system coordinate system after the point location is positioned and transformed by a user, so that the operation process is complicated, and the name of the original point location is lost.

Description

Technical Field

[0001] This invention relates to the field of digital design and manufacturing technology, and specifically to a method and apparatus for automatic measurement of point coordinates based on a user coordinate system in a CATIA environment. Background Technology

[0002] Digital design and manufacturing rely on precise spatial data to construct digital models and optimize design schemes through simulation and analysis to implement precision manufacturing. Point coordinates, as a key element in realizing digital model design, play a central role in the entire process. Precise point coordinate measurement is the core support for digital precision manufacturing and plays a crucial role in modern manufacturing and engineering fields. Whether it's aircraft, automobiles, spacecraft, or ships, the design and realization of these complex products depend on precise point data to ensure their geometric accuracy, performance, and functionality. The core competitiveness of digital precision manufacturing stems from the precise control of spatial information, and the foundation of this process is high-precision point coordinate measurement and application. Position coordinate measurement technology in the user coordinate system is the key means of obtaining this critical point information.

[0003] While CATIA allows for the rapid acquisition of point coordinates in the system coordinate system through programming, it lacks a direct interface for developing point measurement solutions in the user coordinate system. Point measurement based on the user coordinate system typically requires manual transformation of the point location before measurement in the system coordinate system. This process is complex, and programming for coordinate system modeling and point location transformations is difficult, often resulting in the loss of original point names. Even performing coordinate system matrix transformations between the user and system coordinate systems cannot preserve the original point names and requires strong mathematical foundations and complex mathematical calculation and programming skills. Summary of the Invention

[0004] The purpose of this invention is to solve the above problems by proposing an automatic measurement method and device for point coordinates based on the user coordinate system in the CATIA environment. This addresses the issue that existing point coordinate data is usually implemented in the system coordinate system, and point measurement based on the user coordinate system usually requires the user to manually transform the point location before measurement in the system coordinate system, which results in a complex operation process and the loss of the original point name.

[0024] This embodiment provides an automatic point coordinate measurement method based on a user coordinate system in a CATIA environment, including the following implementation steps: Step 1: Create a super-copy model of the point location transformation in CATIA software; Step 1 includes: In CATIA software, a reference coordinate system 2 is established using four points, and an instance point 8 is established to perform a point positioning transformation from the reference coordinate system 2 to the system coordinate system 1, thereby obtaining the instance target point 7 in the system coordinate system 1 after transformation. Based on the four points used to establish the reference coordinate system 2, the instance point 8, and the instance target point 7, a point positioning transformation super copy model is established for the instance point 8 to perform a positioning transformation from the reference coordinate system 2 to the system coordinate system 1.

[0025] In one implementation of this invention, step 1 includes: Step 11: Establish system coordinate system 1 in CATIA software; Step 12: In CATIA software, establish four points P1, P2, P3, and P4 as control points for modeling the reference coordinate system. Points P1, P2, P3, and P4 represent the origin (3), X-axis control point (4), Y-axis control point (5), and Z-axis control point (6) of the reference coordinate system, respectively. Each control point can be any point on the corresponding axis of the reference coordinate system. In this embodiment, P1, P2, P3, and P4 are established with the following coordinates: P1=(300,300,300), P2=(350,300,300), P3=(300,350,300), P4=(300,300,350) Step 13: Establish a reference coordinate system 2 based on the four points P1, P2, P3, and P4, and establish a point as instance point 8 under the reference coordinate system 2. In this embodiment, the coordinates of instance point 8 are (400, 410, 420). Step 14: Establish the point positioning transformation of instance point 8 from reference coordinate system 2 to system coordinate system 1, so as to obtain instance target point 7 in system coordinate system 1 after transformation; Step 15: Using the four points P1, P2, P3, and P4 in reference coordinate system 2 as input elements, the coordinates of instance point 8 as input parameters, and instance target point 7 as output elements, establish a super copy model for the positioning transformation of instance point 8 from reference coordinate system 2 to system coordinate system 1.

The total number of points n and the information of each point to be measured are obtained. Four control points are established in the user coordinate system 10. For each point to be measured in the set of points to be measured, the target point in the system coordinate system 1 after transformation is obtained by iteratively calling the super copy model of point positioning change established in step 1. The coordinates of each target point are measured. The coordinate transformation of all points to be measured in the set of points to be measured is completed to obtain the point information of each target point set TP, and the data is output.

Where i is the loop variable, with an initial value of 1 and a value range of (1, n); sna is the name of the i-th test point; sx is the X-coordinate of the i-th point to be measured; sy is the Y-coordinate of the i-th point to be measured; sz is the Z-coordinate of the i-th point to be measured; In this embodiment, the point information of the set of points to be measured P is shown in Table 1, and the total number of points n=4.

The four points UP1, UP2, UP3, and UP4 are the origin 11, X-axis control point 12, Y-axis control point 13, and Z-axis control point 14 of the user coordinate system, respectively. The control points of each axis can be any point on the corresponding axis of the user coordinate system. In this embodiment, UP1, UP2, UP3, and UP4 are established in the user coordinate system, with the following coordinates: UP1=(120,150,240); UP2=( 123.4810, 112.5344, 272.9274); UP3=(164.3525, 137.2240,220.7743); UP4=(142.8196, 180.5467,272.3445); Step 43: By calling the super copy model of the point location change established in Step 1, obtain the i-th target point TPi in the system coordinate system 1 after transformation; Step 44: Measure the coordinates TPi(tx,ty,tz) of the i-th target point TPi in the transformed system coordinate system 1 using the measurement function. Step 45: Assign the name in the information Pi(sna,sx,sy,sz) of the i-th point to be measured in the system coordinate system 1 to the i-th target point TPi, that is, obtain the point information TPi(sna,tx,ty,tz) of the i-th target point TPi. Step 46: Repeat steps 41 to 45 to complete the coordinate transformation of all points in the set of points to be measured P, and establish the point information of the target point set TP in the system coordinate system 1 after the transformation. Step 47: Output the point information of the changed target point set TP (as shown in Table 2) to complete the automatic measurement of point coordinates based on user coordinate system 10 in the CATIA environment.
