Abstract
There is provided a robot including a first light source, a second light source, an image sensor and a processor. The processor is used to calculate an image quality of an image frame captured by the image sensor when the second light source is being turned on. The processor then determines whether to switch the second light source back to the first light source according to the image quality to accordingly identify the material of an operation surface.
Claims20
A movable robot, comprising:
- a first light source, configured to illuminate an operation surface;
- a second light source, configured to illuminate the operation surface;
- an image sensor, configured to capture reflected light from the operation surface to output image frames;
- and
- a processor, coupled to the first light source, the second light source and the image sensor, and configured to
- switch an operating light source from the first light source to the second light source in identifying a material of the operation surface, and
- determine the material of the operation surface according to whether the operating light source is switched back to the first light source or not.
