[0052] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0053] In a first aspect, an embodiment of the present invention provides an image deformation device.

[0054] Reference Figure 1 , Figure 1 Schematic diagram of the hardware structure of an embodiment of the image deformation device of the present invention. In an embodiment of the present invention, the image deformation device may include a processor 1001 (such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components; the user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard); the network interface 1004 may optionally include a standard wired interface, a wireless interface (such as a wireless fidelity WIreless-FIdelity, WI-FI interface); the memory 1005 may be a high-speed random access memory (random access memory, RAM), or a stable memory (non-volatile memory), such as a disk memory. The memory 1005 may also be a storage device independent of the aforementioned processor 1001. Those skilled in the art will understand that Figure 1 The hardware structure shown in the figure does not constitute a limitation of the present invention, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0055] Continue to refer to Figure 1 , Figure 1 The memory 1005 as a computer storage medium may include an operating system, a network communication module, a user interface module, and an image deformation program. The processor 1001 may call the image deformation program stored in the memory 1005 and execute the image deformation method provided by the embodiment of the present invention.

[0056] In a second aspect, an embodiment of the present invention provides an image deformation method.

[0057] In order to more clearly demonstrate the image deformation method provided in the embodiment of the present application, the application scenario of the image deformation method provided in the embodiment of the present application is first introduced.

[0058] The image deformation method provided in the embodiment of the present application is applied to embedded vehicle-mounted devices. By using the cross-programming language and cross-platform OpenGL ES open graphics interface, the deformation effect of the original image is displayed. For example, when we need to display a navigation lane line, because the shape of the route will change randomly according to the actual road conditions, if the image is drawn by using the original navigation image in a proportional manner, a good display effect cannot be achieved. At this time, it is necessary to consider the real-time changing shape of the route, and draw the route into a corresponding shape according to the navigation data without causing image display distortion. In addition, in some cases, it is necessary to deform the image into an arbitrary shape to achieve a cool display effect.

[0059] In one embodiment, referring to Figure 2 , Figure 2 FIG. 1 is a flow chart of an embodiment of an image deformation method according to the present invention. Figure 2 As shown, the image deformation method includes:

[0060] Step S10 : selecting a preset number of first feature points from the initial image based on the texture coordinate system.

[0061] In this embodiment, refer to Figure 3 , Figure 3 Schematic diagram of the texture coordinate system and vertex coordinate system of an embodiment of the image deformation method of the present invention. Figure 3 As shown, the texture coordinates in the texture coordinate system represent the mapping relationship between the texture and the image. In the texture coordinate system, each point in the image corresponds to a texture coordinate, which means that the texture data of the image is read from that position. The range of texture coordinates is between 0 and 1. The default lower left corner of the texture coordinate is (0, 0) and the upper right corner is (1, 1). The initial image is the initial image to be deformed in this embodiment. In the field of image processing, a feature point refers to a point where the grayscale value of the image changes dramatically or a point with a large curvature on the edge of the image (i.e., the intersection of two edges). It usually has the characteristics of rotation invariance, illumination invariance, and perspective invariance.

[0062] In step S20, a deformed shape is set based on a vertex coordinate system, and a preset number of second feature points are selected from the deformed shape. The second feature points correspond one-to-one to each of the first feature points, and the order between each of the second feature points is consistent with the order between each of the first feature points.

[0063] In this embodiment, continue to refer to Figure 3 ,like Figure 3 As shown, the vertex coordinates in the vertex coordinate system represent the mapping relationship between the image and the screen, that is, the feature points in the image are displayed at that position on the screen. The range of vertex coordinates is between -1 and 1. Generally, the center point of the vertex coordinate system is set to coincide with the center point of the screen. The deformation shape can be customized according to the deformation requirements. The second feature point in the vertex coordinate system and the first feature point in the texture coordinate system must be a one-to-one mapping relationship, and the position order between each point must also remain unchanged to avoid misalignment and distortion of the drawn image.

[0064] Step S30: setting the distribution positions of the second feature points according to the deformed shape.

[0065] In this embodiment, after the deformation shape is set, the distribution position of the second feature point is set according to the deformation shape. Since the vertex coordinates of the second feature point represent the display area on the screen, according to the desired deformation effect, for example, if you want to highlight the head area of ​​the deformation shape, you can distribute a larger number of feature points in the head area and a smaller number of feature points in other limbs and torso areas.

[0066] Step S40 , performing drawing based on the texture coordinates of the first feature point and the vertex coordinates of the second feature point to obtain a drawn deformed image.

[0067] In this embodiment, refer to Figure 4 and Figure 5 , Figure 4 This is a flow chart of drawing a normal image in accordance with an embodiment of the image deformation method of the present invention. Figure 5 FIG. 1 is a flow chart of drawing a deformed image according to an embodiment of the image deformation method of the present invention, as shown in FIG. Figure 5 As shown, after the texture coordinates of the first feature point and the vertex coordinates of the second feature point are determined, image data can be taken from the initial image according to the position of the texture coordinates, and then the image data is displayed on the screen at the position where the vertex coordinates are located, thereby realizing the drawing of the deformed image.

[0068] In this embodiment, since the texture coordinates of the first feature point represent the position of the initial image from which the image data is taken, and the vertex coordinates of the second feature point represent the position on the screen where the image data is displayed, drawing can be performed based on the texture coordinates of the first feature point and the vertex coordinates of the second feature point to obtain a drawn deformed image. The deformed shape can be set as needed, thereby realizing the deformation of the initial image into any shape. Since OpenGL ES will automatically perform interpolation operations between each vertex, the drawn deformed image will not produce abnormal distortion of the image display. In addition, the deformation shape can be adjusted in real time to achieve a cool effect of dynamic deformation of the image.

[0069] Furthermore, in one embodiment, before step S10, the following steps are included:

[0070] Set the size of the preset number based on the drawing accuracy of the deformed image.

[0071] In this embodiment, the number of feature points is set accordingly according to the rendering accuracy of the deformed image. For example, if the rendering accuracy requirement of the deformed image is high, a larger number of feature points is selected accordingly to improve the rendering accuracy of the image.

[0072] Furthermore, in one embodiment, step S10 includes:

[0073] Based on the texture coordinate system, an initial image is selected from the image to be deformed according to the deformation area to be processed;

[0074] According to the main content to be drawn, a preset number of first feature points are selected from the initial image.

[0075] In this embodiment, we can choose to deform the entire image or select part of the image area for deformation. For example, for a full-body image of a person, we can select the image area where the head is located for deformation. According to the main content of the drawing, the position of the first feature point is set accordingly. For example, for an image of a person's head, we want to focus on the person's eyes, that is, we can select a larger number of feature points in the image area where the eyes are located, and select a smaller number of feature points in other head image areas except the eyes.

[0076] Furthermore, in one embodiment, step S40 includes:

[0077] Constructing a first array based on the texture coordinates of the first feature point;

[0078] Constructing a second array based on the vertex coordinates of the second feature point;

[0079] Based on the first array and the second array, shading is performed through the OpenGL ES API;

[0080] Based on the first array and the second array, create a texture through the OpenGL ES API;

[0081] Drawing is performed through the glDrawArrays function of the opengles API.

[0082] In this embodiment, the texture coordinates of the first feature point and the vertex coordinates of the second feature point are respectively organized into the form of arrays, each element in the array is the coordinate value of each feature point, which is transmitted to the shader through the OpenGL ES API for shading, and then the texture is created to finally realize drawing.

[0083] Furthermore, in one embodiment, step S40 further includes:

[0084] Based on the first feature points, performing triangular cutting on the initial image to obtain a first triangular network;

[0085] Based on the second feature point, performing triangular cutting on the deformed shape to obtain a second triangular network;

[0086] Constructing a third array based on the texture coordinates of the first triangle network;

[0087] Constructing a fourth array based on the texture coordinates of the second triangle network;

[0088] Based on the third array and the fourth array, shading is performed through the OpenGL ES API;

[0089] Based on the first array and the second array, creating a texture through the opengles API;

[0090] Drawing is performed through the glDrawArrays function of the opengles API.

[0091] In this embodiment, as needed, the initial image can be triangulated according to the first feature point, and the deformed shape can be triangulated according to the second feature point. The image deformation process and the expected deformation effect can be observed intuitively. Since the objects drawn by the opengles bottom layer for image drawing only include points, lines and triangles, cutting in advance can correspondingly improve the processing efficiency of image deformation. In the case of cutting triangles, it is necessary to construct a two-dimensional array for the texture coordinates of the first feature point and the vertex coordinates of the second feature point respectively, wherein the first dimension includes all the cut triangles, that is, each element of the array corresponds to each triangle, and the second dimension includes the coordinate values ​​of each point of each triangle. The constructed two-dimensional third array and fourth array are transferred to the shader through the opengles API for shading, and then the texture is created to finally realize drawing.
