Description

Technical Field

[0001] The present invention relates to the field of camera technology, and in particular to a method for suppressing and eliminating highlights on an object surface which greatly improves the accuracy of photo modeling. Background Art

[0002] Photogrammetry technology has been developed to date and has become a very common technology that uses continuous and overlapping images for modeling.

[0003] However, for some objects with smooth surfaces and high reflections, photo modeling still has major flaws in the final image modeling. The reason is that in non-studio and outdoor situations, smooth surface objects will produce a clear highlight for a clear light source, and the image captured at the position and edge of the highlight loses the surface properties of the object itself, which causes trouble for the final photo modeling. When performing image calculations, the RGB color value of the highlight area is 1, and the calculation results of the image overflow in the sampling process, reflecting that the mesh model will not be generated in this area for many existing objects in reality. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a method for suppressing and eliminating highlight on the surface of an object, which greatly improves the accuracy of photo modeling, thereby avoiding the occurrence of highlight problems and ensuring that the overall brightness of the photo is appropriate.

[0005] The present invention provides a method for suppressing and eliminating highlight on the surface of an object, which greatly improves the accuracy of photo modeling, and comprises the following steps:

[0006] Polarizing the initial light emitted to the object to obtain polarized light with a preset vibration direction;

[0007] After the polarized light propagates to the surface of the object, the surface of the object reflects the polarized light;

[0008] The reflected polarized light is polarized again to enter the camera;

[0009] Brightness enhancement processing is performed so that the camera obtains photos with appropriate brightness.

[0010] In one embodiment, the polarization processing of the initial light emitted to the object to obtain polarized light with a preset vibration direction further includes:

[0011] Arrange a vertical polarizer or a horizontal polarizer in the propagation direction of the initial light emitted by the light source;

[0012] The initial light is polarized by a vertical polarizer or a horizontal polarizer to obtain vertically polarized light or horizontally polarized light.

[0013] In one embodiment, the reflected polarized light is subjected to a re-polarization process to enter a camera, further comprising:

[0014] Arranging a polarizing plate on the camera that is perpendicular to the propagation direction of the polarized light;

[0015] The polarized light is polarized again by the polarizing plate so as to enter the camera.

[0029] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the description of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In the description of the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connection" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0031] The directions or positional relationships indicated by terms such as “upper”, “lower”, “left”, “right”, “front”, “back”, “top”, “bottom”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the inventive product is usually placed when used. They are only for the convenience of description and simplified description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0032] The terms "first", "second", "third", etc. are merely used to distinguish elements of similar nature, and do not indicate or imply relative importance or a particular order.

[0033] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0034] See also Figure 1 The method for suppressing and eliminating highlight on the surface of an object, which greatly improves the accuracy of photo modeling, provided by the present invention, comprises the following steps:

[0035] S1, performing polarization processing on the initial light emitted to the object to obtain polarized light with a preset vibration direction.

[0036] It is understandable that the above steps may further include:

[0037] S101, placing a vertical polarizer or a horizontal polarizer in the propagation direction of the initial light emitted by the light source.

[0038] It can be known that the shooting location can be indoors, the indoors can be a studio, the light source can be an artificial light source, and both artificial light sources and natural light are non-polarized light. Non-polarized light can be understood as light whose vibration plane is not limited to a fixed direction, that is, the vibration plane includes multiple directions. When a vertical polarizer is used, the vertical polarizer only allows vertically polarized light to pass through, and the rest of the light will be filtered. When a horizontal polarizer is used, the horizontal polarizer only allows horizontally polarized light to pass through, and the rest of the light will be filtered.

[0039] S102, the initial light is polarized by a vertical polarizer or a horizontal polarizer to obtain vertically polarized light or horizontally polarized light.

[0040] S2: After polarized light propagates to the surface of an object, the surface of the object reflects the polarized light.

[0041] It is understandable that after polarized light propagates to the surface of an object, it will still be reflected in the original state of light, and the reflection is diffuse reflection, that is, the reflected light of vertically polarized light is still vertically polarized light, and the reflected light of horizontally polarized light is still horizontally polarized light.

[0042] S3, the reflected polarized light is polarized again to enter the camera.

[0043] It is understandable that the above steps may further include:

[0044] S301, arrange a polarizing plate on the camera that is perpendicular to the propagation direction of the polarized light.

[0045] It can be understood that, in the case where the polarized light is vertically polarized light, the polarizer adopts a horizontal polarizer, and in the case where the polarized light is horizontally polarized light, the polarizer adopts a vertical polarizer, which can filter the light once again.

[0046] S302, the polarized light is polarized again through a polarizing plate so as to enter a camera.

[0047] S4, performing brightness enhancement processing so that the camera can obtain photos with appropriate brightness.

[0048] It is understandable that the above steps may further include:

[0049] Change the camera to a larger aperture.

[0050] It is understandable that switching to a larger aperture can increase the overall amount of light entering.

[0051] Increase the ISO (light sensitivity) of your camera.

[0052] It can be known that the purpose of increasing the brightness is to increase the brightness of the photos taken by the camera.

[0053] Keep the camera shutter open longer.

[0054] It is understandable that the longer the shutter is open, the more light enters, thus enhancing the brightness of the photo. The above methods can be selected at will, or used in combination to ensure that the brightness of the photo taken is appropriate.

When the computer program is executed by a processor, any one of the above-mentioned methods for suppressing and eliminating highlights on the surface of an object that greatly improves the accuracy of photo modeling is implemented.

[0062] From the above description, it can be known that the method for suppressing and eliminating highlight on the object surface provided by the present invention, which greatly improves the accuracy of photo modeling, performs polarization processing on the emitted light source to obtain polarized light. After the polarized light is reflected by the object, it is polarized again to be transmitted to the camera, and the amount of reflected light is enhanced, which not only avoids the occurrence of highlight problems, but also makes the overall brightness of the photo appropriate.

[0063] See also Figure 2 , the quality of the model generated by the photos taken by the above method will be much higher, Figure 2 The left side in the middle is a model generated by a picture taken without using the present invention.
