Detailed Description
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1 to 3, the present invention provides a color sampling device for isolating ambient light interference, which mainly includes a light shield 100 and a sampling platform 200.
The top of the light shield 100 is provided with a guide surface 110, the guide surface 110 has a shooting hole 120, the sampling platform 200 is obliquely arranged at the bottom of the light shield 100, the object 300 to be tested is placed on the sampling platform 200, and the standard color carrier 400 is arranged around the object 300 to be tested, so that the sampling platform 200 presents an inclination angle theta relative to the guide surface 110.
The color sampling device of the present invention needs to be used with a handheld camera 500, the handheld camera 500 can be a camera, a mobile phone, a tablet computer, etc., and has a lens 510 for shooting, the handheld camera 500 is close to the guiding surface 110, so that the lens 510 of the handheld camera 500 is aligned with the shooting hole 120, and the lens 510 shoots the object 300 to be tested and the standard color carrier 400 on the sampling platform 200 in an oblique direction.
The key point of the present invention is to eliminate the influence of ambient light on the photographing to ensure the real color of the object 300 to be measured, so the light-shielding cover 100 is first used to isolate the interference of ambient light from the outside, and then the lens 510 is prevented from being directed to the sampling platform 200, but facing the sampling platform 200 in an inclined direction, so that the light in the light-shielding cover 100 is not directly emitted into the lens 510 from the sampling platform 200 to affect the photographing result.
The color sampling device of the present invention, which is composed of the above structure, has the following practical operation mode:
1. fixing the object 300 on the sampling platform 200, and selecting a suitable standard color (e.g. test paper, color card) according to the type of the object 300 to be tested to be installed on the standard color carrier 400, so that the standard color carrier 400 is disposed around the object 300 to be tested;
2. positioning the handheld camera 500 on the guiding surface 110 such that the lens 510 passes through the camera hole 120 and faces the sampling platform 200, wherein the lens 510 also faces the sampling platform 200 in an inclined direction due to the inclination angle θ of the sampling platform 200 relative to the guiding surface 110;
3. the object 300 and the standard color carrier 400 on the sampling platform 200 are photographed to obtain a target image.
The target image obtained as described above can eliminate the interference of ambient light to the greatest extent, has the most real color of the object 300 to be measured, and then provides the relevant color inspection equipment for subsequent processing.
Although the light shield 100 and the sampling platform 200 isolate the interference of ambient light to the greatest extent, it is still inevitable that a small amount of light may affect the real color of the object 300 to be tested, therefore, the present invention provides the standard color carrier 400 to further provide the standard color under the same environment, so that the color inspection equipment can compare the color difference between the object 300 to be tested and the standard color carrier 400 to obtain a more accurate result.
The sampling platform 200 is provided with a movable supporting plate 210 for supporting the object 300 to be tested, and the movable supporting plate 210 can be movably inserted into or removed from the sampling platform 200, so as to conveniently place or replace the object 300 to be tested, thereby improving the operation efficiency.
In order to precisely control the light distribution in the light shield 100, an auxiliary light source 130 may be disposed inside the light shield 100 to irradiate the object 300 and the standard color carrier 400, so as to maintain the accuracy of the photographing result.
Besides the auxiliary light source 130 is disposed inside the light shield 100, the flashlight 520 disposed in the handheld camera 500 can also provide illumination on the object 300 and the standard color carrier 400.
In addition, the two standard color carriers 400 can be disposed at the same time and placed at the front and back or the left and right sides of the object 300 to be tested, and further more standard color carriers 400 can be disposed on the sampling platform 200 to shoot the object 300 and the plurality of standard color carriers 400, thereby providing the subsequent color inspection equipment for more accurate color inspection.
The above embodiments are merely illustrative of the technical concept and features of the present invention, and the present invention is not limited thereto, and any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of the present invention.
