An auto clean machine, comprising:
- a light source configured to emit light to illuminate at least one light region;
- a first image sensing area, configured to sense a first brightness distribution of the light region, wherein a resolution for a horizontal direction of the first image sensing area is higher than a resolution for a vertical direction of the first image sensing area;
- a second image sensing area below the first image sensing area, configured to sense a second brightness distribution of the light region, wherein a resolution for a vertical direction of the second image sensing area is higher than a resolution for a horizontal direction of the second image sensing area;
- and
- a processor, configured to control movement of the auto clean machine according the first brightness distribution and the second brightness distribution.
An auto clean machine control method, comprising:
- emitting light to illuminate at least one light region;
- sensing a first brightness distribution of the light region by a first image sensing area, wherein a resolution for a horizontal direction of the first image sensing area is higher than a resolution for a vertical direction of the first image sensing area;
- sensing a second brightness distribution of the light region by a second image sensing area below the first image sensing area, wherein a resolution for a vertical direction of the second image sensing area is higher than a resolution for a horizontal direction of the second image sensing area;
- and
- controlling movement of the auto clean machine according the first brightness distribution and the second brightness distribution.
