predicts an incorrect polygon with upload geo image

### Steps to reproduce
- input coordinates(extent for geo image): 118.2596535119999999,30.9013170959999997;118.2914085419999992,30.9297128549999982
- result by clicking on the map:

### What is expected?
The predicted polygons should be within the input coordinates (extent for geo image).

### What is actually happening?
The predicted polygons is not within the input coordinates (extent for geo image).
