High-precision map epoch coordinate conversion method, device, equipment, medium and product

The invention provides a high-precision map epoch coordinate conversion method and device, equipment, a medium and a product, and the method comprises the steps: obtaining plate speed observation data which are plate movement speeds of coordinate points where a plurality of observation stations are located, carrying out the grid division of a high-precision map based on a first proportion, and obtaining a plurality of grid regions; for each grid region, calculating by using an Euler vector method based on the data to obtain a surface velocity; calculating the difference between the surface speeds of any adjacent grid areas, and judging whether the difference meets a preset condition or not; when it is determined that the difference of the surface speeds which do not meet the preset condition exists, the corresponding grid area continues to be processed until the preset condition is met, smoothing processing is conducted on the corresponding surface speed meeting the preset condition through a smoothing differ
