[0042] According to one embodiment of the present invention, an embodiment of an image processing method is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0043] This method embodiment can be executed on a mobile terminal, computer terminal, or similar computing device. Taking running on a mobile terminal as an example, the mobile terminal can be a smartphone (such as an Android phone, iOS phone, etc.), tablet computer, PDA, mobile Internet Device (MID), PAD, game console, and other terminal devices. Figure 1 This is a hardware structure block diagram of a mobile terminal for an image processing method according to an embodiment of the present invention. For example... Figure 1 As shown, a mobile terminal may include one or more ( Figure 1 Only one is shown in the diagram. A processor 102 (which may include, but is not limited to, a central processing unit (CPU), graphics processing unit (GPU), digital signal processing (DSP) chip, microprocessor (MCU), programmable logic device (FPGA), neural network processor (NPU), tensor processor (TPU), artificial intelligence (AI) type processor, etc.) and a memory 104 for storing data are also shown. Optionally, the mobile terminal may further include a transmission device 106 for communication functions, an input / output device 108, and a display device 110. Those skilled in the art will understand that... Figure 1 The structure shown is for illustrative purposes only and does not limit the structure of the mobile terminal described above. For example, the mobile terminal may also include components that are more... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.

[0044] The memory 104 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the image processing method in this embodiment of the invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, thereby implementing the aforementioned image processing method. The memory 104 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory.

[0048] In related technologies, drawing rotated graphics requires manually creating objects at different angles, a complex process. Figure 2 This is a flowchart of an image processing method based on existing technology, such as... Figure 2 As shown, it can generally be summarized into the following steps:

[0049] Step S202: Draw the front part.

[0050] Step S204: Determine the desired angle and perspective effect.

[0051] Step S206: Draw the front view of the prop according to the perspective structure based on the perspective view.

[0052] Figure 3a It is a schematic diagram of a complex image that needs to be drawn, such as... Figure 3a As shown, the front part of the image can be drawn first. Figure 3b It is a schematic diagram of the desired angle and perspective effect, such as Figure 3b As shown, the desired angle can be set to rotate 15 degrees to the right. Figure 3c It is a schematic diagram of a pre-drawn complex image, such as... Figure 3c As shown, complex frontal images can be drawn according to perspective structure based on perspective effects.

[0053] The methods used in these related technologies are time-consuming and require personnel with a certain level of technical and artistic skill. In traditional game art production, objects have numerous material details and complex structures. Therefore, using these methods for graphic design results in extremely high production costs.

[0054] Figure 4 This is a flowchart of an image processing method according to one embodiment of the present invention, such as... Figure 4 As shown, the method includes the following steps:

[0055] Step S402: Obtain the height map of the drawn image, wherein the drawn image includes multiple first pixels, and the height map is used to represent the height information of each first pixel in the drawn image.

[0056] The images mentioned above can be images from the game scene that need to be drawn. Optionally, the images can be characters, items, tools, etc. in the game, such as masks, clothing patterns, etc.

[0057] The height map described above can include the brightness of each location within the drawn image, where the height of the image represents the brightness of the color at each location. Optionally, the drawn image can be illuminated by the same beam of light, and the height of each location can be determined based on the degree of light reflection from bright to dark at different locations in the drawn image. Brighter locations have higher heights than darker locations. The light source can be X-rays, ordinary white light, etc., and the type of light is not limited here. Optionally, a corresponding detection model can also be used to detect the brightness of the image's colors to obtain the height map of the drawn image.

[0058] In one optional embodiment, the height of an object in a height map can be obtained by establishing a coordinate system in three-dimensional space, with the origin of the coordinate system as the reference, the z-axis pointing downwards as the direction, and the z-axis as the numerical value. For example, if the brightness of a certain position in the drawn image is high, then the height of that position in the three-dimensional image under illumination can be on the same horizontal plane as the coordinate axis. If the brightness of another position in the drawn image is moderate, then the coordinate of that position in the three-dimensional image can be concave downwards along the z-axis. Specifically, the brightness of different positions in the drawn image can be represented by specific numerical values. For example, the height of a certain position on the same horizontal plane as the coordinate axis can be represented by the value 0, and the brightness of another position in the drawn image is moderate, and the coordinate of that position is concave downwards along the z-axis can be represented by the value -1.

[0059] The first pixel mentioned above can be the color information of each position of the object contained in the drawn image. Specifically, the specific pixel value can be determined according to the color lookup table (Red Green Blue, abbreviated as RGB).

[0060] The height information of the first pixel mentioned above can be used to represent the brightness information of each position of an object in the drawn image.

[0061] In another optional embodiment, the drawn image can be illuminated with light, and a corresponding height map can be obtained based on the degree of light reflection by the drawn image. Optionally, the height of brighter areas under the same light beam can be set to a larger value, and the height of darker areas under the same light beam can be set to a smaller value. Optionally, the drawn image can also be captured by a camera, and the height values ​​of different locations in the drawn image can be determined based on the color intensity of different positions in the captured image, wherein the height value of lighter areas is greater than the height value of darker areas, thereby obtaining a height map of the drawn image. Optionally, the brightness information of the image's colors can also be converted into corresponding height values ​​using a conversion function, thereby obtaining a height map of the drawn image, wherein the conversion function can be used to convert the brightness of the image's colors into specific height values.

[0062] Optionally, after obtaining the height map, each position in the drawn image can be mapped to each position in the image obtained after rotating the drawn image. The pixel value of the first pixel at each position in the drawn image can be determined as the pixel value of the same position in the image obtained after rotating the drawn image, thereby reducing the workload of artists and further improving the efficiency of drawing images from all angles.

[0063] Step S404: Rotate the drawn image according to the preset rotation information to obtain a rotated image, wherein the rotated image includes multiple second pixels.

[0064] The aforementioned preset rotation information can be used to represent information such as the rotation angle and direction of the drawn image. The preset rotation information can be set according to requirements; for example, it can be set to rotate 15 degrees to the right or 30 degrees to the left.

[0065] The aforementioned rotated image can be an image obtained by rotating the drawn image according to preset rotation information. The rotated image does not contain the specific pixel value of each position in the image.

[0066] The aforementioned multiple second pixels can be used to represent the color pixel value at each position of the image contained in the rotated image, wherein the second pixel may not contain a specific pixel value.

[0067] In one optional embodiment, the positions of the rotated image and the drawn image can be mapped using a height map, thereby determining the pixel value of the first pixel in the drawn image as the pixel value of the second pixel at the same position in the rotated image. This can be achieved by having the same ray pass through both the drawn image and the rotated image simultaneously, and determining the positional correspondence between them based on the height map. Alternatively, the drawn image and the rotated image can be placed in the same coordinate system, with the origin determined on the rotation axis. Based on the coordinate information and rotation angle, the positional correspondence between the drawn image and the rotated image can be mathematically calculated, thereby determining the pixel values ​​of multiple second pixels based on the positional correspondence.

[0068] Step S406: Based on the drawn image, height map and rotated image, determine the target pixel point corresponding to each second pixel point among multiple first pixel points.

[0069] The target pixel mentioned above can be a pixel in the drawn image that represents the same position as the rotated image, where the target pixel can include the pixel value of that point.

[0070] In one optional embodiment, a coordinate system can be established, and the drawn image can be fixed on the coordinate plane with one edge of the drawn image coinciding with the y-axis. Then, the drawn image is rotated around the y-axis by a preset rotation angle to obtain a rotated image. Simultaneously, light is used to illuminate the drawn image and the rotated image to obtain a height map corresponding to the drawn image. Optionally, three intersection points of the light ray with the drawn image, the rotated image, and the height map can be obtained. Optionally, the first pixel point at the intersection point of the light ray and the height map, perpendicular to the drawn image, can be determined as the target pixel point, and the pixel value of the target pixel point can be determined as the pixel value of the intersection point of the light ray and the rotated image.

[0071] In another alternative embodiment, a mathematical model can be established and a mathematical algorithm can be used to directly correspond the image positions of the drawn image and the rotated image, thereby determining the pixel values ​​in the drawn image as the pixel values ​​at the same position in the rotated image.

[0072] Furthermore, by establishing a correspondence between the drawn image and the rotated image in terms of image position, it is possible to obtain the pixel values ​​of the rotated image without manually redrawing it, thereby greatly improving work efficiency and reducing the cost of image drawing.

[0073] Step S408: Draw the rotated image based on the target pixel corresponding to each second pixel to obtain the target image.

[0074] The target image mentioned above can be a rotated image containing pixel values.

[0075] In one optional embodiment, the position in the rotated image where the pixel value needs to be obtained can be determined first, and the corresponding position in the drawn image at the same position can be determined. Optionally, the pixel at the corresponding position in the drawn image can be determined as the target pixel, and the pixel value corresponding to the target pixel can be determined as the pixel value at the position in the rotated image where the pixel value needs to be obtained. Optionally, the above steps can be repeated until the pixel values ​​at all positions in the rotated image are determined, and the rotated graphic is drawn according to the pixel values ​​to obtain the target image.

[0076] In at least some embodiments of the present invention, a height map of a drawn image is obtained, wherein the drawn image includes a plurality of first pixels, and the height map is used to represent the height information of each first pixel in the drawn image; the drawn image is rotated according to preset rotation information to obtain a rotated image, wherein the rotated image includes a plurality of second pixels; a target pixel corresponding to each second pixel among the plurality of first pixels is determined based on the drawn image, the height map, and the rotated image; the rotated image is drawn based on the target pixel corresponding to each second pixel to obtain a target image. It is readily apparent that after obtaining the height map, the drawn image and the rotated image can be correlated in position using the height map, thereby using the first pixels of the drawn image to determine the second pixels of the rotated image and obtain the target pixel, and then using the target pixel to draw to obtain the target image. This allows the user to obtain the target image without redrawing, improving work efficiency and reducing drawing costs, thereby solving the technical problem of low efficiency in image drawing in related technologies.

[0077] Optionally, obtaining the height map of the drawn image includes: obtaining image information of each first pixel in the drawn image; determining a preset basic shape based on the contour information of the drawn image; determining a preset height map corresponding to the preset basic shape; and obtaining the height map based on the product of the image information of each first pixel and the preset height map.

[0078] The image information described above can be used to represent the information of the first pixel in the drawn image. The image information may include, but is not limited to, the position information of the first pixel and the pixel value corresponding to the first pixel.

[0079] The aforementioned contour information is used to represent the contour of the object depicted in the drawn image.

[0080] The aforementioned preset basic shape can be a shape that closely resembles the objects contained in the drawn image. Optionally, the preset basic shape can be set by the user, such as a sphere, a hexahedron, etc. Optionally, if the drawn image is a mask, the preset basic shape can be set to a circle; if the drawn image is a honeycomb, the preset basic shape can be set to a hexagon.

[0081] The aforementioned preset height map can be used to represent the color and brightness of a preset basic shape.

[0082] In one optional embodiment, the drawn image can be first divided to obtain multiple first pixels at different locations in the drawn image. Optionally, after obtaining multiple first pixels, the pixel values ​​of the multiple first pixels can be obtained based on their color information. Further, a preset basic shape can be determined based on the approximate outline of the image contained in the drawn image. For example, if the drawn image is a kite, the outline information of the drawn image can be considered as the object being close to a rhombus, so the preset basic shape can be a rhombus.

[0083] Furthermore, after determining the preset basic shape, the preset basic shape of the drawn graphic can be converted into a preset height map using a transformation model or corresponding transformation formula. Figure 5 This is a preset height map according to one embodiment of the present invention, such as... Figure 5 As shown, when the preset base shape is a circle, the preset height map obtained under lighting can be a circle whose brightness gradually decreases from the center to the edges. Optionally, the image information of the first pixel can be multiplied with the preset height map to obtain a height map with details.

[0084] Optionally, a height map is obtained based on the product of the image information of each first pixel and a preset height map, including: determining the color information of each first pixel based on the image information of each first pixel in the drawn image; performing a conversion process on the color information of each first pixel to obtain the brightness information of each first pixel; performing a conversion process on the image information of each first pixel to obtain the brightness information of each first pixel; and obtaining the height map based on the product of the brightness information of each first pixel and the preset height map.

[0085] The color information mentioned above can be the color of the first pixel, for example, the first pixel is red, or the first pixel is green.

[0086] In one optional embodiment, the color information of each first pixel can be converted based on the preset formula Height(color)=color·(0.299,0.587,0.114) to obtain the brightness information of each first pixel. Optionally, the preset formula is not limited to this.

[0087] Where Height represents height, color represents color, and 0.299, 0.587, and 0.114 are specific height values. Optionally, preset formulas can be used to convert color and image information into height information. Figure 6 This is a height information map of an image drawn according to one embodiment of the present invention, such as... Figure 6As shown, the contour information of the drawn image can be converted into height information using a preset formula, thereby determining the brightness information of each first pixel in the drawn image. Figure 6 The image can be seen to contain the outline information of the image and the brightness of different positions.

[0088] In another optional embodiment, the color information and image information of each first pixel can be converted using a preset formula to obtain a height information diagram of the drawn image. Optionally, after obtaining the image information of the first pixel and the preset height map, the obtained image information of the first pixel and the preset height map can be multiplied to obtain a height map. Figure 7 This is a height map according to one embodiment of the present invention, such as... Figure 7 As shown, the height map obtained after multiplication contains detailed texture information of the graphics contained in the drawn image.

[0090] The first plane mentioned above can be the plane where the rotated image is located.

[0091] The aforementioned preset point can be a light source point or the starting point of a ray. Optionally, a light ray can be emitted from the preset point and pass through the rotating image to determine the height information corresponding to multiple second pixel points on the rotating image. The preset point can be the location of the virtual camera.

[0092] The target point mentioned above can descend step by step along the ray. Optionally, when the ray passes through the rotated image, the height of the target point on the ray can be calculated, and the target point can be controlled to descend step by step along the ray according to the height of the target point until the target point reaches the position recorded in the height map. Figure 8 This is a schematic diagram of the intersection of a preset point and a first plane according to one embodiment of the present invention, as shown below. Figure 8 As shown, a light beam can be emitted from a preset point and pass through the rotating image.

[0093] The aforementioned target angle can be the angle between the ray and the first plane. Figure 9 This is a schematic diagram of a target included angle according to one embodiment of the present invention, such as... Figure 9 As shown, when the ray passes through the first plane, there is a certain angle between it and the first plane.

[0094] In one optional embodiment, the target point on the ray can be controlled to descend step by step along the ray until the target point reaches the same height in the height map. Optionally, a perpendicular line can be drawn from the intersection point to the drawing image, and the first pixel point at the position perpendicular to the intersection point and the drawing image can be determined as the target pixel point. The pixel value of the target pixel point can be determined as the pixel value at the intersection point of the ray and the rotated image.

[0095] Optionally, the target point is controlled to descend stepwise along the ray based on the target angle between the ray of each second pixel and the first plane until the target point of each second pixel intersects with the height map, thus obtaining the intersection position of the target point of each second pixel with the height map. This includes: controlling the target point to descend stepwise along the ray based on the target angle between the ray of each second pixel and the first plane to obtain the height information of the target point; determining whether the height information of the target point corresponding to each second pixel is consistent with the height information in the height map, and obtaining a comparison result; in response to the existence of a discrepancy between the height information of the target point corresponding to each second pixel and the height information in the height map, continuing to execute the step of descending stepwise along the ray based on the target angle between the ray of each second pixel and the first plane to obtain the height information of the target point in the ray; in response to the consistency between the height information of the target point corresponding to each second pixel and the height information in the height map, determining the current position of the target point corresponding to each second pixel as the intersection position of the ray of each second pixel with the height map.

[0096] The height information of the target point mentioned above can be the height information of the target point at different time points during the ray descent process.

[0097] Figure 10 This is a schematic diagram of target point movement according to one embodiment of the present invention, such as... Figure 10 As shown, the descent height of the ray can be monitored in real time during the descent process. The height information of the target point is compared with the height information in the height map to determine whether the height information of the target point corresponding to each second pixel is consistent with the height information in the height map. If they are inconsistent, it means that the target point has not yet touched the height map, and the descent needs to continue. If they are consistent, it means that the height information of the target point corresponding to each second pixel is consistent with the height information in the height map. Therefore, the current position of the target point corresponding to the second pixel can be determined as the intersection point of the ray and the height map for each second pixel. Furthermore, the pixel value of the current position of the target point corresponding to the second pixel can be determined through this position.

[0098] Optionally, the target point is controlled to descend step by step along the ray based on the target angle between the ray of each second pixel and the first plane to obtain the height information of the target point, including: obtaining the difference between a preset value and the cosine value of the target angle; and controlling the target point to descend step by step along the ray based on the difference to obtain the height information of the target point.

[0099] The above preset values ​​can be set by the user, for example, setting the preset value to 1, but are not limited to this.

[0100] Figure 11 This is a schematic diagram of a ray descent according to one embodiment of the present invention, such as... Figure 11 As shown, the drawn image can be placed on the xy plane with the z-axis set to 0, and the camera looking towards the -z-axis. The drawn image is then rotated based on rotation information. Optionally, after rotating the drawn image, for any point on this plane, there exists a line A, which is the vector from the camera to that point. Simultaneously, a tangent space exists for this plane, containing three standard vectors: the tangent, normal, and bitangent at that point on the plane, forming a Cartesian coordinate system. That is, vector A can be transformed into this tangent space. Optionally, the cosine of the target angle can be calculated within this Cartesian coordinate system and used as a parameter for each ray descent. This parameter is then subtracted from a preset value until the target point contacts the height map.

[0101] Optionally, the drawn image is rotated according to preset rotation information to obtain a rotated image, including: determining the rectangular coordinate system corresponding to the drawn image; determining the first preset axis and rotation angle corresponding to the rectangular coordinate system based on the preset rotation information; and controlling the drawn image to rotate along the preset axis based on the rotation angle to obtain a rotated image.

[0102] The first preset axis mentioned above can be the rotation axis for drawing the image.

[0103] In one optional embodiment, after obtaining preset rotation information, the drawn image can be rotated based on the rotation axis and rotation angle in the preset rotation information to obtain a rotated image. Taking the X-axis of the Cartesian coordinate system as an example, when the first rotation axis is the X-axis of the Cartesian coordinate system, the drawn image can be rotated along the X-axis of the Cartesian coordinate system.

[0104] Optionally, the rotating image is drawn based on the target pixel corresponding to each second pixel to obtain the target image, including: acquiring the pixel value corresponding to the target pixel corresponding to each second pixel; filling each second pixel based on the pixel value corresponding to the target pixel corresponding to each second pixel to obtain the target image.

[0105] In one optional embodiment, after obtaining the target pixel, the pixel value of the target pixel can be collected and determined as the pixel value of the corresponding second pixel. Optionally, the second pixel can be filled using the pixel value until each second pixel is filled, thereby obtaining a target image with color.

[0106] Furthermore, by using the above method, only the drawn image and the desired 3D angle are required to obtain the rotated target image, thereby reducing the image production time and the product production cycle, which in turn increases the output during working hours and reduces production costs.
