Augmented reality technology based printed circuit board information indication method and apparatus

Abstract

The present invention discloses an augmented reality technology based printed circuit board information indication method and apparatus. The method comprises the steps of: 1) acquiring a real scene image of a target printed circuit board; 2) acquiring a theoretical design model of the target printed circuit board, and calculating an image mapping relationship between the theoretical design model and the real scene image; 3) acquiring a theoretical design coordinate position of a specified part on the target printed circuit board, and calculating an image coordinate position of the specified part in the real scene image; and 4) projecting and displaying indication information corresponding to the specified part onto a projection position, wherein the projection position is a position, which corresponds to the image coordinate position of the specified part, on the target printed circuit board. The apparatus comprises a corresponding image acquisition module, a corresponding image mapping relationship calculation module, an corresponding image position calculation module and a corresponding indication information display module. The method and apparatus disclosed by the present invention have the advantages of being simple for implementation, capable of directly displaying information of the printed circuit board onto the corresponding position and convenient for rapidly searching for and recognizing the part and the like.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a printed circuit board information indication method and device based on augmented reality technology. Background technique [0002] Printed circuit boards (hereinafter referred to as circuit boards) are the core components of various electronic devices. Therefore, with the development of human society and technology, the number of circuit boards is huge, and the circuit structure is becoming more and more complex. The most specific manifestation is the components on the circuit board. The number is increasing, while the volume of components is getting smaller and smaller. In the stage of manual assembly and welding of circuit boards, the stage of R&D and debugging, and the repair stage of failures, it is often necessary for staff to repeatedly search for a specified component, pin, and pad on the circuit board. Repeatedly looking for the corresponding relationship betwe...

Problems solved by technology

In the stage of manual assembly and welding of circuit boards, the stage of R&D and debugging, and the repair stage of failures, it is often necessary for staff to repeatedly search for a specified component, pin, and pad on the circuit board. Repeatedly look for the corresponding relationship between the actual circuit board and the circuit board design drawing, this time-consuming and laborious operation greatly reduces the efficiency of circuit board assembly, welding and debugging
