Catia-based hydrogen energy automobile combination instrument imaging checking system and method

Abstract

The invention provides a Catia-based hydrogen energy automobile combination instrument imaging checking system and method. The method comprises the steps of equally dividing the boundary of the internal assembly of the combination instrument into a plurality of points; defining an imaging point on the front windshield; selecting one point on the boundary as a light-emitting point, drawing a straight line formed by the normal, an incident light, a reflected light, a light-emitting point and an imaging point based on the light-emitting point, the imaging point, the eye point, the front windshield and the boundary of the internal assembly of the combination instrument, and judging whether the straight line formed by the light-emitting point and the imaging point coincides with the incident light or not; if yes, selecting one point on the boundary again to serve as a light-emitting point, and repeating the steps; if not, optimizing the position of the imaging point by adopting a simulatedannealing algorithm until a straight line formed by the light-emitting point and the imaging point coincides with the incident light; and finally, repeating the above steps until each point on the boundary is traversed, and obtaining an image of the internal assembly of the combination instrument in the front windshield. According to the invention, the working efficiency can be improved, and the accuracy can be well ensured.

[0002] With the iterative upgrade of automobile design technology, the traditional vehicle design mode has been broken. Looking back at the previous design methods and working methods, the low-end repetitive labor operation methods can no longer adapt to daily tedious tasks. At this time, fast and accurate The operation method of completing the work is extremely eager. The future automobile design stage must belong to efficient and rigorous designers with an international vision. In order to improve the flexibility of updating and modifying to improve work efficiency, the operation process combined with the application concept of knowledge engineering came into being. pregnancy

[0003] The traditional reflective imaging calibration method of combined instrument is calibrated by special modules in UG or CAVA 3D software. This kind of method needs to install several softwares at the same time to convert the data format back and forth, and the results are all in the form of elimination. In the form of parameters, if the input conditions change in the later stage, the output results need to be recreated, which is cumbersome, time-consuming and inefficient; Catia plays an important role in the reflective imaging calibration of the instrument cluster, but Catia does not target the reflective instrument Modules for Image Calibration
