Abstract

The present disclosure provides a color recognition device and a color recognition method, and belongs to the technical field of color recognition. In an embodiment, the color recognition device includes a head portion and a main body portion; the head portion has a groove in which a sensor module configured to capture color information of the object to be detected is disposed; and the main body portion includes: a storage module configured for storing standard color parameters of a variety of colors, and a central processing unit configured for comparing color information of the object to be detected with the standard color parameters of the variety of colors stored in the storage module, to recognize color of the object to be detected.

First claim

What is claimed is:

1. A color recognition device, comprising a head portion and a main body portion; wherein:
the head portion has a groove in which a sensor module configured to capture, by virtue of ambient light, color information of an object to be detected is disposed;
the main body portion comprises: a storage module configured for storing standard color parameters of a variety of colors, and a central processing unit configured for comparing color information of the object to be detected with the standard color parameters of the variety of colors stored in the storage module, to recognize color of the object to be detected; and
the groove is provided therein with a light source configured to offer brightness to the object to be detected in a darkroom state which is formed when the groove is in contact with the object to be detected, the light source comprising a standard white-color light source.

2. The device of claim 1 , wherein the sensor module comprises an imaging unit, a color filtering unit and a color processing unit;
the imaging unit is configured to perform an imaging process on the object to be detected;
the color filtering unit is configured to separate color in an image of the object to be detected into red, green and blue gray scale brightness; and
the color processing unit is configured to capture values of the gray scale brightness in the image of the object to be detected.

3. The device of claim 2 , wherein the imaging unit comprises a lens.

4. The device of claim 2 , wherein the color filtering unit comprises a Complementary Metal Oxide Semiconductor (CMOS) sensor.

5. The device of claim 1 , wherein the main body portion further comprises a communication module and a power module;
the communication module is configured to transmit the color information of the object to be detected to an upper computer; and
the power module is configured to supply the power to the device.

6. The device of claim 5 , wherein the communication module comprises one of a Bluetooth module, a wireless fidelity (Wi Fi) module, an infrared module and a Near Field Communication (NFC) module.

7. The device of claim 5 , wherein the power module comprises a battery cell and a power management unit.

8. The device of claim 1 , wherein the device further comprises: a standard white board configured to correct the color information of the object to be detected when the object to be detected is in a state of non-darkroom.

9. A color recognition method applied to the color recognition device of claim 1 , the method comprising the following steps of:
capturing, by the sensor module, color information of the object to be detected;
judging, by the central processing unit, whether or not there is ambient light in the groove; and
acquiring, by the central processing unit, standard color parameters of a variety of colors pre-stored in the storage module, and, comparing, by the central processing unit, color information of the object to be detected with the standard color parameters of the variety of colors, to obtain a color recognition result.

10. The method of claim 9 , wherein the sensor module comprises an imaging unit, a color filtering unit and a color processing unit, and the step of capturing, by the sensor module, color information of the object to be detected, further comprises the following sub-steps of:
performing, by the imaging unit, an imaging process on the object to be detected;
separating, by the color filtering unit, color in an image of the object to be detected into red, green and blue gray scale brightness; and
capturing, by the color processing unit, values of the gray scale brightness in the image of the object to be detected.

11. The method of claim 10 , further comprising the following step of:
transmitting, by the communication module, the color recognition result to an upper computer.

12. The method of claim 9 , wherein before the step of comparing, by the central processing unit, the color information of the object to be detected with the standard color parameters of the variety of colors, to obtain a color recognition result, the method further comprises the following steps of:
converting, by the central processing unit, the color information of the object to be detected into a digital signal; and
comparing, by the central processing unit, the color information of the object to be detected with the standard color parameters of the variety of colors, to obtain the color recognition result.

13. The method of claim 12 , further comprising the following step of:
transmitting, by the communication module, the color recognition result to an upper computer.

14. The method of claim 9 , wherein after the step of judging, by the central processing unit, whether or not there is ambient light in the groove, the method further comprises the following steps of:
in response to judging that there is no ambient light in the groove, acquiring, by the central processing unit, standard color parameters of the variety of colors pre-stored in the storage module, and, directly comparing the color information of the object to be detected with the standard color parameters of the variety of colors, to obtain the color recognition result; or
in response to judging that there is ambient light in the groove, capturing, by the sensor module, color information of a standard white board in the current condition; correcting, by the central processing unit, the color information of the object to be detected in accordance with the color information of the standard white board; and, comparing, by the central processing unit, the corrected color information with the standard color parameters of the variety of colors, to obtain the color recognition result.

15. The method of claim 14 , further comprising the following step of:
transmitting, by the communication module, the color recognition result to an upper computer.

16. The method of claim 9 , further comprising the following step of:
transmitting, by the communication module, the color recognition result to an upper computer.
