Abstract
An image capturing apparatus and a mobile cleaning robot are provided. The image capturing apparatus includes a light emitter, an image sensor, and a filter. The light emitter is configured to emit an invisible light to a target. The image sensor includes a field of view (FOV) covering an area of the target from near to far and is configured to sense the invisible light reflected from the area of the target and generate an image of the area of the target. The filter is configured to filter the invisible light to transform the invisible light into a non-uniform invisible light.
Claims17
An image capturing apparatus, comprising:
- a light emitter emitting an invisible light to a target;
- an image sensor having a field of view (FOV) covering an area of the target from near to far, sensing the invisible light reflected from the area of the target and generating an image of the area of the target;
- and
- a filter filtering the invisible light to transform the invisible light into a non-uniform invisible light with intensity variation, wherein the filter adjusts a gradient transmission rate of the light emitter, so that the invisible light emitted by the light emitter is transformed into a non-uniform invisible light whose intensity changes in a gradient, and wherein a light transmittance of the filter used varies depending on a distance indicated by an included angle between a camera direction and a horizontal line.
A mobile cleaning robot, comprising:
- a body;
- and
- an image capturing apparatus configured in the body, comprising:
- a light emitter emitting an invisible light to a target;
- an image sensor having an FOV covering an area of a target from near to far, sensing the invisible light reflected from the area of the target and generating an image of the area of the target;
- and
- a filter filtering the invisible light to transform the invisible light into a non-uniform invisible light with intensity variation, wherein the filter adjusts a gradient transmission rate of the light emitter, so that the invisible light emitted by the light emitter is transformed into a non-uniform invisible light whose intensity changes in a gradient, and wherein a light transmittance of the filter used varies depending on a distance indicated by an included angle between a camera direction and a horizontal line.
