Definitions
- the invention relates to a method for the recognition of surfaces, in particular for the optical detection of structured and / or pictorial surfaces, for example of paintings or sculptures.
- Another stationary optical device for detecting surfaces of a component is described in DE 102008018586 A1.
- Two light sources and a camera device are provided, the camera receiving the light beams of the light sources reflected on the surfaces of the component in order to generate an image of the surfaces.
- FIG. 2 the camera according to FIG. 1 with a glare protection.
- the camera 5 is focused if, for example, there is no refocusing of the lens of the camera 5 within approx. 0.5 seconds.
- the physical position of the lens of the objective is continuously monitored. As far as the average of the obtained lens positions of the lens of the camera 5 from the last approx. 0.5 seconds corresponds to the next obtained lens position, the camera 5 is classified as focused and triggered by the software of the mobile device 4.
- Each individual image of the live video stream is sent to a subroutine in the control electronics for processing (individual frames can be left unprocessed, to the detriment of accuracy).
- High-contrast image points 3 are identified in each image to be processed. Colors, contrasts, distances and / or depths of structures are automatically determined. These image points 3 are surrounded by significantly more or less intense image points.
- Geometric shapes are then projected using the high-contrast image points 3 identified. These pixels 3 form the corners of the projected geometric figures.
- the number, the positions and the sizes of the geometric figures are stored in a data record for each image.
- the target image or target image that is to be found in the video stream is processed.
- the data records of the target image and the single image with the highest level of detail are compared with one another. If the target image is found in the individual image of the video, this can be determined by comparing the data sets.
- the number of projected geometric figures indicates the depth of detail in an image.
- the image with the highest level of detail, ie the greatest number of details, is selected for further processing and saved or saved as a reference (target image). was created and saved at an earlier point in time.
- step 9 To ensure that the saved image is suitable as a reference for a fingerprint, another image of the selected area is created as described above and saved as a secondary reference image. 10. The reference image from step 8 and the secondary reference image from step 9 are used for future comparisons of the selected area.
- the user wants to determine whether a work of art / object available to him corresponds to the object originally recorded in the registration process or is identical to it.
- step 8 of the registration process is now used to obtain the best possible image in accordance with steps 6 and / or 7 of the registration
