Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Example one
Fig. 1 is a flowchart of steps of a picture processing method according to an embodiment of the present invention, which is applied to a terminal, and as shown in fig. 1, the method may include:
In an embodiment of the present invention, the first size data may include a size of the first picture in a horizontal direction, that is, a width of the first picture, and a size of the first picture in a vertical direction, that is, a height of the first picture, where a unit of the width and the height may be a pixel (px). Specifically, the user may set a specific width value and a specific height value according to actual requirements, and after receiving the specific width value and the specific height value, the terminal may draw the first picture according to the width value and the specific height value. For example, assuming a width of 4096px and a height of 2048px, the terminal may draw a rectangular picture of size 4096px 2048px, resulting in the first picture.
And 102, establishing a first coordinate axis in the horizontal direction of the first picture and a second coordinate axis in the vertical direction of the first picture by taking the preset point of the first picture as an origin to obtain a reference coordinate system.
In this step, the preset point may be preset according to a requirement, preferably, the preset point is a central point of the first picture, and the central point of the first picture is used as the preset point, so that after the drawn picture is displayed as a three-dimensional picture in a subsequent process, a viewing angle of a user can fall in the center of the picture, the viewing range of the user is ensured to be maximum, and the viewing effect of the user is further improved. Further, when the first coordinate axis is a horizontal axis, the second coordinate axis may be a vertical axis, and when the first coordinate axis is a vertical axis, the second coordinate axis may be a horizontal axis, that is, when a reference coordinate system is established, the horizontal axis may be established in a horizontal direction, the vertical axis may be established in a vertical direction, or the vertical axis may be established in a horizontal direction, and the horizontal axis may be established in a vertical direction, which is not limited in the embodiments of the present invention.
And 103, adding degree marks to the first coordinate axis and the second coordinate axis based on the visual angle range of the user and the first size data to obtain a second picture.
In the embodiment of the invention, the visual angle range of the user is determined according to the range which can be seen by the sight of the user in an actual scene, wherein the visual angle range can comprise 0-360 degrees of a first visual angle range of the user in the horizontal direction and 0-180 degrees of a second visual angle range of the user in the vertical direction. Accordingly, indicia of degrees may include indicia corresponding to each degree in the first range of angles of visibility and indicia corresponding to each degree in the second range of angles of visibility.
In the step 202, the reference coordinate system established in the first picture, the first coordinate axis and the second coordinate axis use the pixel value as the measurement standard, and in this step, degree marks may be added to the first coordinate axis and the second coordinate axis, that is, both the first coordinate axis and the second coordinate axis can use the degree as the measurement standard to obtain the second picture, which is convenient for drawing in the second picture according to the degree of the object to be drawn in the subsequent steps.
And 104, determining the size degree of the object to be drawn based on the size parameter of the object to be drawn, and determining the position coordinate degree of the object to be drawn based on the relative position of the object to be drawn and the preset point.
In the embodiment of the present invention, in an actual application scene, an actual size parameter of an object to be drawn is usually used to represent a space occupied by an object in reality, but due to an influence of a user's perspective, the objects with different sizes may feel that the two objects have the same size at the same perspective, that is, the objects occupying the spaces with different sizes may be considered to be the same at the user's perception, and therefore, when drawing is performed in the prior art, space conversion needs to be performed according to different distances between each object to be drawn and the user's perspective in the scene to be drawn, thereby increasing workload in the drawing process. In practice, the occupation degrees of objects with the same size are not affected by the distance, so in the implementation of the invention, the dimension degrees of the objects are calculated according to the dimension parameters of the objects to be drawn, and the position coordinate degrees of the objects to be drawn are determined based on the relative position of the objects to be drawn and the preset point, namely, the space occupied by the objects and the distance between the objects and the visual center of a user are reflected by the degrees, so that the operation of space conversion is avoided, and the drawing process can be simplified.
And 105, drawing the object to be drawn in the second picture according to the size degree and the position coordinate degree to obtain a target picture.
In the embodiment of the invention, the planar image of the object to be drawn can be drawn in the second picture according to the size degree and the position coordinate degree of the object to be drawn to obtain the target picture, so that compared with the drawing of a three-dimensional object to be drawn, the difficulty of the drawing process is reduced, and the drawing process is simplified.
106, displaying the target picture to a user through preset display equipment; the preset display equipment is used for generating a virtual focal length based on the target picture and displaying the target picture based on the virtual focal length.
In this embodiment of the present invention, the preset display device may be a virtual panorama player installed inside the terminal, or may be an entity panorama player, such as a cardboard box, and the like, and the panorama player may be integrated with the terminal, or may be separated from the terminal and disposed in front of eyes of the user. Further, the preset display apparatus is capable of generating a virtual focal length based on the target picture and displaying the target picture based on the virtual focal length, so that by generating the virtual focal length, it is possible to pre-distort the two-dimensional target picture, since the viewing angle of each eye of the user looking at things is different, and the binocular vision system in the brain calculates the distance using the difference, so that the user can see the three-dimensional stereoscopic target picture.
In summary, in the image processing method provided in the embodiment of the invention, the terminal can establish the first image according to the first size data input by the user, then, a reference coordinate system is established in a first picture, degree marks are added to a first coordinate axis and a second coordinate axis in the reference coordinate system based on a visual angle range of a user and first dimension data to obtain a second picture, then, the dimension degree of an object to be drawn is determined based on a dimension parameter of the object to be drawn, the position coordinate degree of the object to be drawn is determined based on the relative position of the object to be drawn and a preset point, and then, according to the dimension degree and the position coordinate degree, and drawing the object to be drawn in the second picture to obtain a target picture, and finally displaying the target picture to a user through preset display equipment so that the user can see the three-dimensional target picture. In the embodiment of the invention, the terminal does not need to draw the three-dimensional form of the object to be drawn in the actual scene in the three-dimensional environment, and only needs to draw the plane image of the object to be drawn on the second picture in the plane environment, so that the drawing difficulty is reduced, and the operation process is simplified.
Example two
Fig. 2-1 is a flowchart illustrating steps of a picture processing method according to a second embodiment of the present invention, and as shown in fig. 2-1, the method may include:
Specifically, the step 101 may be referred to in an implementation manner of this step, and this is not limited in this embodiment of the present invention.
Specifically, the step 102 may be referred to in an implementation manner of this step, and this is not limited in this embodiment of the present invention.
Fig. 2-2 is a schematic view of a user visual angle range according to a second embodiment of the present invention, and as can be seen from fig. 2-2, the user can see the angle ranges of 0 to 360 degrees in the horizontal direction and 0 to 180 degrees in the vertical direction, so that in the embodiment of the present invention, the first visual angle range can be set to 0 to 360 degrees, and the second visual angle range can be set to 0 to 180 degrees, thereby ensuring that the user is not hindered and improving the viewing effect of the user. Further, fig. 2-3 are schematic diagrams illustrating a corresponding relationship between a second screen and a visual angle range according to an embodiment of the present invention, as shown in fig. 2-3, a horizontal direction of the second screen represents a first visual angle range of a user in a horizontal direction, and a vertical direction of the second screen represents a second visual angle range of the user in a vertical direction.
Specifically, assuming that the size of the first screen in the horizontal direction is 4096px, and the maximum viewable angle in the first viewable angle range is 360 degrees, the unit of degree that can be obtained for the first coordinate axis is 4096/360 ═ 11.38 (px/degree); assuming that the size of the first screen in the vertical direction is 2048px, and the maximum viewable angle in the second viewable angle range is 180 degrees, the unit of degree of the second coordinate axis is 2048/180 ═ 11.38 (px/degree). Of course, specific values of the size of the first frame in the horizontal direction, the size of the first frame in the vertical direction, the maximum viewing angle in the first viewing angle range, and the maximum viewing angle in the second viewing angle range may be set according to requirements, which is not limited in the embodiment of the present invention.
And 204, adding a mark for the corresponding position of each degree in the first visual angle range on the first coordinate axis based on the degree unit of the first coordinate axis, and adding a mark for the corresponding position of each degree in the second visual angle range on the second coordinate axis based on the degree unit of the second coordinate axis.
Specifically, the product of each degree in the first visual angle range and the degree unit of the first coordinate axis may be calculated, so as to obtain the position of each degree in the first visual angle range on the first coordinate axis, and then a mark may be added to the position corresponding to the degree, where the mark may be a specific value of the degree.
For example, taking 200 degrees in the first visual angle range as an example, the following can be obtained through calculation: 200 x 11.38 — 2276px, a mark with the content "200" may be set at 2276px on the first coordinate axis.
Accordingly, the product of each degree in the second visual angle range and the degree unit of the second coordinate axis can be calculated, so as to obtain the corresponding position of each degree in the second visual angle range on the second coordinate axis, and then a mark can be added to the corresponding position, wherein the mark can be a specific value of the degree.
For example, taking 100 degrees in the second visual angle range as an example, the following can be obtained through calculation: 100 × 11.38 ═ 1138px, then a label with the content "100" may be set at 1138px of the second coordinate axis.
Specifically, in the embodiment of the present invention, the size degree may be a degree of each feature line segment in the to-be-drawn plane image corresponding to the to-be-drawn object. Accordingly, in this step, the determination of the degree of the size of the object to be rendered based on the size parameter of the object to be rendered can be realized by the following substeps (1) to (3):
substep (1): and determining the projection of the object to be drawn on the visual plane of the user by taking the preset point as the visual center of the user to obtain a planar image to be drawn corresponding to the object to be drawn.
In this step, the preset point is taken as the visual center of the user, and the user stands at the position indicated by the preset point to view the object to be drawn. In the embodiment of the invention, the form of the object to be drawn in the user view angle can be predefined according to the design requirement, namely, the relative position relation between the object to be drawn and the user is predefined, and further the planar image to be drawn of the object to be drawn can be obtained. For example, assuming that the object to be drawn is a sofa, and the designer may define the sofa in front of the right of the user in advance, the sofa shape seen by the user, that is, the projection of the sofa on the visual plane of the user, may be determined as the planar image to be drawn.
Substep (2): and selecting at least one characteristic line segment on the plane image to be drawn, and determining the length of each characteristic line segment based on the size parameter of the object to be drawn.
In this step, the characteristic line segment may be a line segment that needs to be drawn when the planar image to be drawn is drawn, and the characteristic line segment may be a straight line segment or a curved line segment, which is not limited in the embodiment of the present invention. Specifically, the designer may pre-define the feature line segments in different planar images to be drawn, so as to facilitate selection by the terminal. For example, assuming that the planar image to be drawn is a rectangular box, the characteristic line segment may include two first line segments in a horizontal direction representing the length of the box and two second line segments in a vertical direction representing the height of the box, it should be noted that, in practical applications, other characteristic line segments may also be included, which is not limited in this embodiment of the present invention. Further, the size parameter of the object to be drawn may be preset according to actual requirements, and the size parameter may be different for different objects to be drawn, for example, when the object to be drawn is a box, the size parameter may include: box length, box width, box height, and box diagonal length, etc., when the object to be drawn is a sphere, the size parameters may include the diameter of the request, etc.
After determining the characteristic line segments, the length of each characteristic line segment may be searched for in the size parameter of the object to be drawn, or the length of the characteristic line segment may be calculated according to the size parameter of the object to be drawn. For example, the length of the first line segment may be the box length in the dimension parameter, and the length of the second line segment may be the box height in the dimension parameter.
Substep (3): and calculating the product of the length of each characteristic line segment and a preset length degree unit to obtain the degree of each characteristic line segment.
In this step, the preset length degree unit represents the corresponding degree when the length is 1. The specific value of the preset length degree unit may be predefined by a designer, specifically, the designer may simulate a basic unit in a three-dimensional environment in advance, and select and determine a suitable degree as the preset length degree unit by adjusting the basic unit. For example, assuming that the degree unit is 5 degrees/cm, the length of the first line segment is 12cm, and the length of the second line segment is 6cm, the degree of the first line segment is 60 degrees, and the degree of the second line segment is 30 degrees.
Further, the position coordinate degrees in the embodiment of the present invention may include a first coordinate axis position coordinate degree and a first coordinate axis position coordinate degree. Correspondingly, in this step, the following substeps (4) to (5) can be used to determine the degree of the position coordinate of the object to be drawn based on the relative position of the object to be drawn and the preset point:
substep (4): and taking the user with the visual center at the preset point as a reference user, calculating the distance between the center point of the orthographic projection of the object to be drawn and the reference user in the horizontal direction to obtain a first distance, and calculating the distance in the vertical direction to obtain a second distance.
In this step, a rectangle can be constructed by using the position point where the reference user is located and the central point of the orthographic projection of the object to be drawn as the points of two opposite angles of the rectangle; then, the length of the side of the rectangle along the horizontal direction is calculated to obtain a first distance, and the length of the side of the rectangle along the vertical direction is calculated to obtain a second distance.
Substep (5): and calculating the product of the first distance and a preset distance degree unit to obtain a first coordinate axis position coordinate degree of the position coordinate degree, and calculating the product of the second distance and the preset distance degree unit to obtain a second coordinate axis position coordinate degree of the position coordinate degree.
In this step, the preset distance degree unit represents the corresponding degree when the distance is 1. The specific value of the preset distance degree unit may be predefined by a designer, and the distance degree unit may be set to be the same value as the length degree unit in the above step, or may be set to be a different value. For example, assuming that the distance degree unit is 6 degrees/cm, the first distance is 5cm, and the length of the second distance is 5cm, the first coordinate axis position coordinate degree is 60 degrees, and the second coordinate axis position coordinate degree is 30 degrees.
Fig. 2-4 are schematic diagrams of a user perspective provided by a second embodiment of the present invention, as shown in fig. 2-4, it can be seen that, according to the principle of similar triangles, a content 1.5m at a position 3 meters away from a user and a content 2.5m at a position 5 meters away from the user are different in size, and the user perceives the two contents to be the same size under the same perspective of the user, so that in the prior art, when performing rendering, space conversion needs to be performed according to different distances between each object to be rendered and the user perspective in a scene to be rendered, whereas in the implementation of the present invention, a terminal calculates a dimension degree of an object according to a dimension parameter of the object to be rendered, and determines a position coordinate degree of the object to be rendered based on a relative position of the object to be rendered and a preset point, that is, a space occupied by the object and a distance from a visual center of the user are embodied in degrees, thereby avoiding, and the rendering process can be simplified.
And step 206, drawing the object to be drawn in the second picture according to the size degree and the position coordinate degree to obtain a target picture.
Specifically, this step can be realized by the following substeps (6) to (7):
substep (6): and determining a point indicated by the position coordinate degrees in the second picture.
