Light reflectance matching camouflage system
An article of manufacture comprises a surface that includes a first region and a surface treatment over the first region. The first region includes a depiction of a real-world object and the surface treatment exhibits a first light reflectance value. The real-world object exhibits a second light reflectance value, and the first light reflectance value is within 30 percent of the second light reflectance value. The article of manufacture may include an article of clothing or a durable good.
1. A method, comprising:
positioning a light source a first distance away from an object, wherein light emitted from the light source strikes a surface of the object at a first angle;
positioning a light reflectance sensor a second distance away from the object, wherein the light reflectance sensor is oriented at a second angle with respect to the surface of the object;
causing the light source to illuminate the object;
measuring, using the light reflectance sensor, a first light reflectance profile of the object;
positioning the light source the first distance away from a candidate camouflage surface, wherein the light emitted from the light source strikes a surface of the candidate camouflage surface at the first angle;
positioning the light reflectance sensor the second distance away from the candidate camouflage surface, wherein the light reflectance sensor is oriented at the second angle with respect to the surface of the candidate camouflage surface;
causing the light source to illuminate the candidate camouflage surface;
measuring, using the light reflectance sensor, a second light reflectance profile of the candidate camouflage surface; and
comparing the first light reflectance profile to the second light reflectance profile to determine an efficacy of the candidate camouflage surface to mimic the object.
2. The method of claim 1 , wherein the light reflectance sensor is configured to detect light having wavelengths from 380 nm to 740 nm.
3. The method of claim 1 , wherein the light reflectance sensor is configured to detect light having wavelengths from 440 nm to 590 nm.
4. The method of claim 1 , further comprising:
positioning the light source a third distance away from the object, wherein light emitted from the light source strikes a surface of the object at a third angle;
positioning the light reflectance sensor a fourth distance away from the object, wherein the light reflectance sensor is oriented at a fourth angle with respect to the surface of the object;
causing the light source to illuminate the object;
measuring, using the light reflectance sensor, a third light reflectance profile of the object;
positioning the light source the third distance away from a candidate camouflage surface, wherein the light emitted from the light source strikes the surface of the candidate camouflage surface at the third angle;
positioning the light reflectance sensor the fourth distance away from the candidate camouflage surface, wherein the light reflectance sensor is oriented at the fourth angle with respect to the surface of the candidate camouflage surface;
causing the light source to illuminate the candidate camouflage surface;
measuring, using the light reflectance sensor, a fourth light reflectance profile of the candidate camouflage surface; and
comparing the third light reflectance profile to the fourth light reflectance profile to determine the efficacy of the candidate camouflage surface to mimic the object.
5. The method of claim 1 , wherein comparing the first light reflectance profile to the second light reflectance profile includes calculating at least one of a Sørensen-Dice distance and a Jaccard distance between a first data set including the first light reflectance profile and a second data set including the second light reflectance profile.
