Numerical control engraving scanning method and system, storage medium and equipment

Abstract

The invention discloses a numerical control engraving scanning method which comprises the following steps: acquiring laser data recorded at normal time, and continuously moving and continuously scanning the same row of engraved products by adopting a light scanning instrument to obtain the laser data recorded at the normal time, wherein the laser data recorded in the normal time comprises height information when the laser data points are recorded and time information of the laser data points from the beginning of working; subtracting the delay compensation time from the obtained time information of the laser data point from the start of working of the optical scanning instrument to obtain laser time information after delay compensation; obtaining system time coordinates, wherein the system time coordinates comprise horizontal position information of the light scanning instrument and coordinate time information recorded by a control system from the beginning of working; and comparing the laser time information after delay compensation with the coordinate time information to obtain the horizontal position information of the laser data point. The method has the effect of improving the working efficiency of engraving and scanning.

Description

technical field [0001] The present application relates to the field of engraving control, in particular to a numerically controlled engraving scanning method, system, storage medium and equipment. Background technique [0002] CNC engraving refers to the use of CNC equipment to achieve engraving, including engraving stone, glass, wood, etc. This kind of equipment needs to input digital information to be engraved in the computer before engraving. The digital information usually includes the moving distance of the cutter head in the vertical height and the moving distance in the horizontal direction. On this basis, it is also derived to scan the original engraving products and obtain digital information, and finally copy the previously scanned engraving products through the CNC engraving machine. [0003] In related technologies, scanning of engraved products is to use laser measuring instrument or optical scanner and other testing instruments for detecting height to collect ...

Problems solved by technology

[0004] In view of the above phenomenon, the inventor believes that after the detection instruments such as laser measuring instrument or optical scanner detect the digital information of a certain point, the data information needs to pass through the chip circuit Operation and wire transmission can transmit the digital information of this point to the computer. This process takes a certain amount of time. Therefore, in the current scanning operation, the detection instrument has to stay at each point for a period of time, resulting in a decrease in the work efficiency of the entire scan. , still needs to be improved
