[0046] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] Reference Figure 1 , shows a flowchart of a method for displaying a painting provided by an embodiment of the present invention, and the method for displaying a painting may specifically include the following steps:

[0048] Step 101: Get viewing instructions.

[0049] The embodiment of the present invention can collect images of the painting from multiple lighting angles in advance, thereby forming paintings displayed at multiple lighting angles.

[0050] The process of capturing paintings at multiple lighting angles is described in detail in conjunction with the following specific implementation method.

[0051] In a specific implementation of the present invention, before the above step 101, the following steps may also be included:

[0052] Step A1: Divide the target painting into a plurality of painting areas.

[0053] In the embodiment of the present invention, the target painting refers to a painting that needs to be produced from multiple angles. The target painting may be the painting "xxx" created by the famous painter xxx in xxx. Specifically, it may be determined according to business needs, and the embodiment of the present disclosure does not limit this.

[0054] When collecting images of a target painting at multiple lighting angles, the target painting may be divided into multiple areas. For example, Figure 3 , which shows a schematic diagram of a painting area division provided by an embodiment of the present invention, such as Figure 3 As shown, the painting can be divided into areas I11, I12, I13, I21, I22, . . .

[0055] The number of regions into which the target painting is divided may be 9, 10, etc., and may be determined specifically according to business requirements, and the embodiment of the present invention does not impose any limitation on this.

[0056] For the regions divided into the target painting, each region may be of the same size or of different sizes. Specifically, it may be determined according to business requirements, and the embodiment of the present invention does not impose any limitation on this.

[0057] After the target painting is divided into a plurality of painting areas, step A2 is performed.

[0058] Step A2: setting multiple acquisition angles for acquiring the target painting.

[0059] The acquisition angle refers to the angle at which the target painting is acquired. In the present invention, the target painting can be acquired at the lighting angle. Specifically, Figure 2 This is described in detail as follows.

[0060] Reference Figure 2 , which shows a schematic diagram of the structure of a painting collection device provided by an embodiment of the present invention, such as Figure 2 As shown, a ring light source can be set around the camera, and multiple LEDs can be used to serve as multiple lighting angles, and K LED lighting sources (such as Figure 2 As shown, K is 12), the device is also provided with a two-dimensional electric translation stage and a loading platform, wherein the loading platform is used to carry and place the target painting, and the two-dimensional electric translation stage is fixed on the loading platform to provide movement and positioning for the camera assembly. The camera acquisition area is rectangular, and its area is smaller than the size of the painting. Therefore, the camera needs to step and scan the entire painting driven by the translation stage. Each LED light source provides uniform illumination to the acquisition area with a light beam at an incident angle of about 60°. The preferred range of the incident angle of the LED light source beam is 50-70 degrees.

[0061] After setting a plurality of acquisition angles for acquiring the target painting, step A3 is performed.

[0062] Step A3: capturing a regional image corresponding to each of the painting regions at a plurality of capturing angles.

[0063] Fix the painting on the loading platform and plan the entire acquisition process as the acquisition of the painting area according to the painting area and the camera acquisition area, such as Figure 3 As shown, according to the plan, a two-dimensional electric platform is used to drive the camera to step and shoot at each painting area. During the stepping process, the illumination light sources L1, L2, ..., LK are turned on in sequence for one of the painting areas, and the camera takes regional images: Imn1, Imn2, ..., ImnK respectively.

[0064] It can be understood that the above examples are merely examples listed for better understanding of the technical solutions of the embodiments of the present invention, and are not intended to be the sole limitations on the embodiments of the present invention.

[0065] After the regional images corresponding to each painting area are acquired at multiple acquisition angles, step A4 is performed.

[0066] Step A4: stitching the regional images of the plurality of painting regions captured at the same capture angle to generate target paintings at the plurality of capture angles; the designated angle is one of the plurality of capture angles.

[0067] The regional images with the same illumination angle are stitched into one, for example, M*N photos I111, ..., IMN1 are stitched into photos under the oblique illumination of the light source L1, and K oblique illumination paintings with different illumination directions are obtained.

[0068] At the same acquisition angle, after the regional images of multiple painting areas are spliced, the target painting at the acquisition angle can be generated. Multiple acquisition angles constitute the target painting at multiple angles.

[0069] The specified angle mentioned in the following steps is one of the multiple acquisition angles.

[0070] After the regional images of multiple painting regions captured at the same capture angle are spliced ​​to generate target paintings at multiple capture angles, step A5 is executed.

[0071] Step A5: performing fusion processing on the target paintings at the multiple acquisition angles to generate a fused image.

[0072] After obtaining the target paintings at multiple acquisition angles, the target paintings at multiple acquisition angles may be fused to generate a fused image.

[0073] Step A6: Save the target paintings and the fused images at multiple acquisition angles.

[0074] After obtaining the target paintings at multiple acquisition angles and the fused image formed by fusing the target paintings at multiple acquisition angles, the target paintings at multiple acquisition angles and the fused image may be saved.

[0075] It can be understood that the above specific implementation method is only a method of obtaining target paintings and fused images from multiple acquisition angles for a better understanding of the technical solution of the embodiment of the present invention. In the specific implementation, other methods can also be used to obtain target paintings and fused images from multiple acquisition angles. Specifically, it can be determined according to business needs, and the embodiment of the present invention is not limited to this.

[0076] The viewing instruction refers to the instruction for the user to view the target painting.

[0077] It can be understood that the viewing instruction can be an instruction executed by the user to view the target painting from different angles, or it can be an instruction collected by the face image acquisition device that the user wants to view the target painting from different angles. Specifically, it can be determined according to business needs, and the embodiments of the present invention are not limited to this.

[0078] After obtaining the viewing instruction, step 102 is executed, or step 104 is executed.

[0079] Step 102: When the viewing instruction is the first instruction, obtain the viewing angle of the user.

[0080] The first viewing instruction refers to an instruction for the user to view the target painting of the specified acquisition angle from different angles.

[0081] Of course, when it is determined that watching Zhilin is the first instruction, the distance between the user and the target painting can also be obtained. When the distance is large, the fused image is directly displayed, and when the distance is small, the user's viewing angle is obtained. Specifically, it is described in detail in combination with the following specific implementation method.

[0082] In a specific implementation of the present invention, before obtaining the viewing angle of the user, the following steps may also be included:

[0083] Sub-step B1: Obtaining the distance between the user and the target painting.

[0084] In the embodiment of the present invention, the spacing distance refers to the spacing distance between the user and the target painting.

[0085] In the present invention, the depth camera module of the display device can be used to determine the distance between users. This method of obtaining the distance between users is a relatively mature technology in the field, and the embodiments of the present invention will not be described in detail here.

[0086] After obtaining the distance between the user and the target painting, step B2 is performed.

[0087] Sub-step B2: When the interval distance is greater than a threshold distance, display the fused image.

[0088] The threshold distance refers to the distance for viewing the target painting set in advance by the business personnel. For example, the threshold distance is 1m. When the user distance is greater than 1m, it is difficult for the user to observe the details of the surface of the oil painting at this distance. Therefore, the display device only displays the synthesized painting, that is, it can be directly displayed when the interval distance is greater than the threshold distance.

[0089] Sub-step B3: When the interval distance is less than or equal to the threshold distance, executing the step of obtaining the user's viewing angle.

[0090] When the interval distance is less than the threshold distance, the step of obtaining the user's viewing angle is performed.

[0091] When the interval distance is less than the threshold distance, there are two ways to obtain the user's viewing angle: one is to determine the user's viewing angle based on the user's face image, and the other is to determine the user's viewing angle based on the rotation angle of the user's palm. Specifically, it can be described in combination with the two modes of the display device.

[0092] The painting display is completed based on an art display device with a depth camera module. The target painting and fused images collected from multiple acquisition angles are pre-stored in the memory of the display device. The display device supports two display modes: manual mode and automatic mode.

[0093] 1. Automatic mode

[0094] In automatic mode, the display device can judge the distance of the user based on the depth camera module, and determine whether to display the fused image or the target painting from multiple acquisition angles based on the distance of the user. Specifically, it is described in detail in the following specific implementation method.

[0095] In another specific implementation of the present disclosure, the above step 102 may include:

[0096] Sub-step C1: Acquire the facial image of the user.

[0097] Sub-step C2: determining the viewing angle of the user according to the face image.

[0098] In an embodiment of the present invention, when the distance between the user and the target painting is less than a threshold distance, the camera device can capture the user's facial image, identify the user's facial key points through the facial image, and then analyze the user's facial orientation based on the facial key points, and then obtain the angle between the user and the front orientation based on the facial orientation, and determine the angle as the user's viewing angle.

[0099] It can be understood that the above specific implementation methods are merely examples listed for better understanding of the technical solutions of the embodiments of the present invention, and are not intended to be the sole limitation to the embodiments of the present invention.

[0100] 2. Manual mode

[0101] In the manual mode, the display device can detect the translation and rotation of the observer's palm, which will be described in detail in conjunction with the following specific implementation.

[0102] In another specific implementation of the present invention, the above step 101 may include:

[0103] Sub-step D1: monitoring the rotation operation performed by the user's palm toward the target painting;

[0104] Sub-step D2: According to the rotation operation, obtain the rotation angle of the palm, and use the rotation angle as the viewing angle.

[0105] In an embodiment of the present invention, when the user's palm is facing the target painting, the rotation operation performed by the user's palm toward the target painting can be monitored, and the rotation angle corresponding to the rotation operation can be obtained, so as to use the rotation angle as the user's viewing angle. Figure 4 , shows a schematic diagram of a manual control display provided by an embodiment of the present invention, such as Figure 4 As shown, when the user's palm is facing the display device, a camera module can be used to detect the rotation operation of the user's palm.

[0106] After obtaining the viewing angle of the user, step 103 is executed.

[0107] Step 103: According to the target painting acquired in advance using multiple acquisition angles, the target painting at a specified angle matching the viewing angle is acquired and displayed.

[0108] The display device stores target paintings of multiple acquisition angles that are acquired in advance, and acquires a target painting of a specified angle that matches the viewing angle according to the viewing angle. For example, when the viewing angle is 45°, a target painting of a acquisition angle of 45° can be acquired, and the target painting of a acquisition angle of 45° can be used as the target painting of the specified angle.

[0109] It can be understood that the above examples are merely examples listed for better understanding of the technical solutions of the embodiments of the present invention, and are not intended to be the sole limitations on the embodiments of the present invention.

[0110] After obtaining the target painting at the specified angle, the target painting at the specified angle may be directly displayed.

[0111] Specifically, in manual mode, when the camera module detects that the user's palm is sliding to the right, the display device switches to various oblique lighting display modes. At this time, a digital painting with 0° oblique lighting is loaded, and then the camera module detects whether the palm is rotated. When the palm rotation is detected, it is accumulated on the basis of 0°, clockwise is positive, and counterclockwise is negative. The display device switches to the painting display with the corresponding oblique lighting condition according to the current angle accumulation value.

[0112] In automatic mode, when the face is facing forward, the display device presents a synthetic fused image. When the face is facing tilted, the camera device calculates the angular orientation of the face based on the facial key points, and the display device presents the target painting at the acquisition angle corresponding to the orientation.

[0113] Step 104: When the viewing instruction is the second instruction, display the fused image.

[0114] In the present invention, the second instruction may be an instruction obtained when it is detected that the distance between the user and the target painting is greater than a distance threshold; or it may be an instruction obtained when the camera module detects that the palm slides to the left or to the right.

[0115] When the viewing instruction is the second instruction, the fused image may be directly displayed.

[0116] The painting display method provided by the embodiment of the present invention can provide observers with more accurate oil painting brush and ink texture information, helping observers to understand the painter's creative ideas.

[0117] The painting display method provided by the embodiment of the present invention obtains a viewing instruction, obtains the viewing angle of the user when the viewing instruction is a first instruction, obtains and displays the target painting of a specified angle matching the viewing angle based on the target painting pre-acquired using multiple acquisition angles, and displays a fused image when the viewing instruction is a second instruction. The embodiment of the present invention can provide the observer with more accurate oil painting brush and ink texture information by displaying the target painting acquired at multiple acquisition angles, helping the observer to understand the painter's creative ideas.

[0118] Reference Figure 2 , which shows a schematic diagram of a painting collection device provided by an embodiment of the present invention, such as Figure 2 As shown, the painting acquisition device may include: a stage 210, a light source 220 and a stage moving component (not shown in the figure), wherein:

[0122] In the present invention, the light source may be a ring structure composed of multiple sub-light sources, such as Figure 2As shown, each sub-light source can be an LED (Light-Emitting Diode) light source, the painting acquisition device 230 can be a camera, and the stage moving component can be a two-dimensional electric translation stage. A ring light source can be set around the camera, and multiple LEDs can be used as multiple lighting angles, and K LED lighting light sources (such as Figure 2 As shown, K is 12), the device is also provided with a two-dimensional electric translation stage and a loading platform, wherein the loading platform is used to carry and place the target painting, and the two-dimensional electric translation stage is fixed on the loading platform to provide movement and positioning for the camera assembly. The camera acquisition area is rectangular, and its area is smaller than the size of the painting. Therefore, the camera needs to step and scan the entire painting driven by the translation stage. Each LED light source provides uniform illumination to the acquisition area with a light beam at an incident angle of about 60°. The preferred range of the incident angle of the LED light source beam is 50-70 degrees.

[0123] During the image acquisition process, the target painting can be placed on the stage, and the target painting can be divided into painting areas corresponding to multiple sub-light sources. Each sub-light source is turned on one by one, and the image acquisition device is driven by the stage moving component to align the painting area illuminated by the sub-light source to acquire the painting, thereby obtaining the target painting and fused images at multiple acquisition angles. Figure 2 The specific description is as follows: the painting is fixed on the loading platform, and the entire acquisition process is planned as the acquisition of the painting area according to the painting area and the camera acquisition area, such as Figure 3 As shown, according to the plan, a two-dimensional electric platform is used to drive the camera to step and shoot at each painting area. During the stepping process, the illumination light sources L1, L2, ..., LK are turned on in sequence for one of the painting areas, and the camera takes regional images respectively: Imn1, Imn2, ..., ImnK. The regional images with the same illumination angle are stitched into one, for example, M*N photos I111, ..., IMN1 are stitched into photos under the oblique illumination of the light source L1, and K oblique illumination paintings with different illumination directions are obtained. At the same acquisition angle, after the regional images of multiple painting areas collected are stitched, the target painting at the acquisition angle can be generated. Multiple acquisition angles constitute target paintings at multiple angles. After obtaining the target paintings at multiple acquisition angles, the target paintings at multiple acquisition angles can be fused to generate a fused image.
