Abstract

Systems and methods for automatically grading a user device are provided. Such systems and methods can include (1) a lighting element positioned at an angle relative to a platform, (2) an imaging device positioned at the angle relative to the platform such that light emitted from the lighting element and a field of view of the imaging device form a right angle where the light emitted from the lighting element and the field of view meet at a user device when the user device is positioned at a predetermined location on the platform, and (3) control circuitry that can activate the lighting element, instruct the imaging device to capture an image of a screen of the user device while the user device is at the predetermined location and is being illuminated by the first lighting element, and parse the image to determine whether the screen is damaged.

First claim

What is claimed is:

1. A system comprising:
a first lighting element positioned at an angle relative to a platform;
an imaging device positioned at the angle relative to the platform such that light emitted from the first lighting element and a field of view of the imaging device form a right angle where the light emitted from the first lighting element and the field of view meet at a user device when the user device is positioned at a predetermined location on the platform; and
control circuitry that activates the first lighting element, instructs the imaging device to capture an image of a screen of the user device while the user device is at the predetermined location and is being illuminated by the first lighting element, and parses the image to determine whether the screen is damaged.

2. The system of claim 1 further comprising:
a second lighting element,
wherein the first lighting element is positioned above the platform,
wherein the second lighting element is positioned below the platform, and
wherein the control circuitry activates the second lighting element simultaneously with the first lighting element and instructs the imaging device to capture the image while the user device is at the predetermined location and is being illuminated by the first lighting element and the second lighting element.

3. The system of claim 1 wherein, when the control circuitry determines that the screen is damaged, the control circuitry assigns the user device a low cosmetic grade and directs the platform to maneuver the user device to a first end location dedicated for user devices having damaged screens.

4. The system of claim 3 wherein, when the control circuitry fails to determine that the screen is damaged, the control circuitry parses the image to determine whether the screen is defective, wherein, when the control circuitry determines that the screen is defective, the control circuitry assigns the user device a medium level cosmetic grade and directs the platform to maneuver the user device to a second end location dedicated for user devices having defective screens, and wherein, when the control circuitry fails to determine that the screen is defective, the control circuitry assigns the user device a high level cosmetic grade and directs the platform to maneuver the user device to a third end location dedicated for undamaged and non-defective user devices.

5. The system of claim 4 wherein the control circuitry determines that the screen is damaged when the control circuitry identifies at least a predetermined number of cracks on the screen depicted in the image, and wherein the control circuitry determines that the screen is defective when the control circuitry identifies at least a predetermined amount of scratches on the screen depicted in the image.

6. The system of claim 4 further comprising:
a housing that encloses the first lighting element and the imaging device,
wherein the platform includes a conveyor belt that maneuvers the user device to the predetermined location within the housing and to the first end location, the second end location, or the third end location after the imaging device captures the image.

7. The system of claim 1 wherein, when the control circuitry determines that the screen is damaged, the control circuitry assigns the user device a cosmetic grade associated with user devices having damaged screens and directs the platform to maneuver the user device to a first end location dedicated for user devices having damaged screens.

8. The system of claim 1 , wherein the first lighting element is a planar light defining a two-dimensional illumination.

9. The system of claim 1 , wherein the first lighting element defines a plane perpendicular to a center angle of the light emitted from the first lighting element, wherein the plane and the imaging device are oriented parallel to each other.

10. A system comprising:
a positioning device;
a first lighting element positioned at a first angle relative to ground;
a first imaging device positioned at the first angle relative to the ground such that light emitted from the first lighting element and a first field of view of the first imaging device form a right angle where the light emitted from the first lighting element and the first field of view meet at a back of a user device when the user device is positioned at a first predetermined location and the back of the user device is positioned in a predetermined orientation by the positioning device; and
control circuitry that activates the first lighting element, instructs the first imaging device to capture a first image of the back of the user device while the user device is at the first predetermined location and the back of the user device is being illuminated by the first lighting element, and parses the first image to determine whether the back of the user device is defective.

11. The system of claim 10 further comprising:
a second lighting element; and
a second imaging device,
wherein the control circuitry activates the second lighting element, activates the positioning device to rotate all sides of the user device through a second field of view of the second imaging device and light emitted from the second lighting element, and instructs the second imaging device to capture second images of the sides of the user device while the user device is being illuminated by the second lighting element,
wherein the control circuitry parses the second images to determine whether any sides of the user device are defective, and
wherein, when the control circuitry determines that the back of the user device or any sides of the user device are defective, the control circuitry assigns the user device a low cosmetic grade and directs a platform to maneuver the user device to a first end location dedicated for user devices having defective backs or defective sides.

12. The system of claim 11 wherein the control circuitry determines that the back of the user device or any sides of the user device are defective when the control circuitry identifies at least a predetermined amount of cracks or scratches on the back of the user device depicted in the first image or the sides of the user device depicted in the second images.

13. The system of claim 11 further comprising:
a third lighting element positioned at a second angle relative to the platform; and
a third imaging device positioned at the second angle relative to the platform such that light emitted from the third lighting element and a third field of view of the third imaging device form a right angle where the light emitted from the third lighting element and the third field of view meet at the user device when the user device is positioned at a second predetermined location on the platform,
wherein, when the control circuitry fails to determine that the back of the user device or any sides of the user device are defective, the control circuitry directs the platform to maneuver the user device to the second predetermined location, activates the third lighting element, and instructs the third imaging device to capture a third image of the user device while the user device is at the second predetermined location and is being illuminated by the third lighting element,
wherein the control circuitry parses the third image to determine whether the screen is defective,
wherein, when the control circuitry determines that the screen is defective, the control circuitry assigns the user device a medium cosmetic grade and directs the platform to maneuver the user device to a second end location dedicated for user devices having defective screens, and
wherein, when the control circuitry fai
