Claim 8:
9. A wafer detection device, comprising:
a processor; and
a memory configured to store instructions executable by the processor;
wherein the processor is configured to:
receive an original wafer picture to be detected;
perform picture segmentation on the original wafer picture to acquire a plurality of first pictures, the plurality of first pictures being partially overlapped;
perform picture zooming on the original wafer picture to acquire a second picture;
perform the picture zooming on the plurality of first pictures to acquire a plurality of third pictures;
sequentially input the second picture and the plurality of third pictures into a wafer detection model to acquire a first detection result corresponding to the second picture and a second detection result corresponding to each third picture; and
determine a total detection result of the original wafer picture according to the first detection result and the plurality of second detection results.
