Referring to fig. 2, an embodiment of a method for drawing a solar curve according to the present application is provided. In this embodiment, the method for drawing a solar curve includes:
step S10, acquiring sunset time and sunrise time;
In the present embodiment, the sunset time and sunrise time here belong to the same day; in other embodiments, the sunset time and the sunrise time may also belong to two adjacent days, for example, two adjacent days are the first day and the second day, respectively, and the first day is earlier than the second day, and the sunset time may be the sunset time of the first day and the sunrise time may be the sunrise time of the second day.
The sunset time and sunrise time can be obtained by accessing the Internet and obtaining solar time data on the Internet. In addition, the sunset time and sunrise time can also be obtained by acquiring data input by a user.
Specifically, the current date can be obtained, and the sunset time and sunrise time are obtained according to the current date; the current date and the date of the day after the current date can also be obtained, the sunset time is obtained according to the current date, and the sunrise time is obtained according to the day after the current date; the sunset time and sunrise time herein may also be acquired according to a date specified by the user.
Step S20, determining curve control parameters according to the sunset time and the sunrise time;
The curve control parameter is specifically a parameter for limiting the curve characteristics of the solar curve in the drawing process of the solar curve. In this embodiment, the curve control parameter is a position point where the solar curve needs to pass through in the drawing area; in other embodiments, the curve control parameter may be a range of values that cannot be exceeded by the point on the solar curve, such as a maximum or minimum allowed by the point on the curve.
Different sunset times and different curve control parameters corresponding to different sunrise times are different. Specifically, sunset time and sunrise time can be used as curve control parameters; the corresponding characteristic time can be calculated according to the sunset time and the sunrise time and used as a curve control parameter; and taking the sunset time, the sunrise time and the characteristic time obtained by calculating the sunset time and the sunrise time as curve control parameters.
The solar curve to be drawn has different time periods, and the sunset time, sunrise time and curve control parameters have different corresponding relations. Based on the method, the time period represented by the solar curve can be determined, and corresponding relations are acquired according to the time period represented by the solar curve to determine curve control parameters corresponding to the current sunset time and sunrise time.
And step S30, drawing a solar curve according to the curve control parameters, wherein the solar curve represents the change characteristic of the position of the sun relative to the horizon with time.
Specifically, a curve function corresponding to a solar curve may be preset, the curve control parameter is used as a known value or a numerical limitation range of the curve function, and a curve corresponding to the curve function meeting the curve control parameter is drawn as the solar curve.
The sun profile may include a first profile that characterizes the change in position of the sun with respect to the horizon over time when the sun is above the horizon, a second profile that characterizes the change in position of the sun with respect to the horizon over time when the sun is below the horizon, and/or a third profile that characterizes the change in position of the sun with respect to the horizon over time over a target time period (which may be user-set or may be a system default parameter).
In this embodiment, the abscissa of each location point on the solar curve characterizes time and the ordinate of each location point characterizes the position of the sun relative to the horizon (i.e. the solar altitude).
According to the method for drawing the solar curve, the sunset time and the sunrise time are used as curve control parameters to draw the solar curve representing the change characteristic of the position of the sun relative to the horizon, so that the drawn solar curve is not in a fixed mode, the curve characteristic of the solar curve can be dynamically adjusted along with the actual sunset time and sunrise time, and the intuitiveness and the accuracy of the curve characteristic of the sunrise curve on the representation of the position of the sun in different scenes are effectively improved. For example, under the extreme day scene and polar night scenes, due to the obvious difference between the sunset time and the sunrise time, the curve characteristics of the drawn sunrise and sunset curves have obvious differences, and a user can accurately and intuitively acquire the change condition of the sun position under different scenes based on the curve characteristics of the sunrise and sunset curves.
Further, based on the above embodiment, another embodiment of the method for drawing a solar curve according to the present application is provided. In this embodiment, referring to fig. 3, the step S30 includes:
and step S30a, drawing a Bezier curve according to the curve control parameters to obtain the solar curve.
In this embodiment, the curve control parameter includes a plurality of known position points of the bezier curve function, and then a bezier curve passing through the plurality of known position points at the same time is plotted as a sun curve.
In this embodiment, the bezier curve drawn by the curve control parameters adapted to the sunset time and the sunset time is used as the sun curve, which is favorable for ensuring that the applicability of the drawing algorithm of the sun curve is effectively improved, and is convenient for an application platform adopting different computer languages to draw an accurate and visual sun curve based on the sunset time and the sunset time, thereby improving the convenience of transplanting the drawing mode of the sun curve to different platforms.
In other embodiments, the sun curve may also be other types of curves, such as sinusoidal, elliptical, etc.
Further, in this embodiment, the solar curve includes a first curve (such as a curve CDE in fig. 4), where the first curve characterizes a change of a position of the sun with respect to the horizon when the sun is above the horizon, and referring to fig. 5, the step of determining a curve control parameter according to the sunset time and the sunrise time includes:
step S21, determining a first target time, the sunrise time and the sunset time as first curve parameters corresponding to the first curve, wherein the curve control parameters comprise the first curve parameters; the first target time is a time when the sun is at a highest position relative to the horizon or a first average of the sunrise time and the sunset time.
In this embodiment, if the time when the sun is at the highest position relative to the horizon is obtained (for example, the time when the sun is at the highest position relative to the horizon is included in the memory of the electronic device, the data input by the current user, or the sun data obtained based on the internet), the first target time is the time when the sun is at the highest position relative to the horizon; otherwise, the first target time is the first average value. In other embodiments, the parameter may also be set by a user, and one of the first average value and the time when the sun is at the highest position relative to the horizon is determined as the first target time according to the user set parameter.
The first target time, sunrise time and sunset time are used as curve control parameters of the first curve, so that the drawn first curve can accurately and intuitively reflect the related conditions of the sun rising above the horizon and the time when the sun is at the highest point.
It should be noted that, in other embodiments, when the first curve is another type of curve other than the bezier curve, the curve control parameters may also include the first curve parameters herein.
Further, based on the above step S21, referring to fig. 5, step S30a includes:
Step S31, drawing a datum line representing a horizon and marking the sunrise time and the sunset time on the datum line;
The reference line is in particular a straight line extending in the transverse direction. Different points on the reference line may characterize different times. The positions of the sunrise time and the sunset time on the reference line differ depending on the time interval between the sunrise time and the sunset time. Defining a point of the sunrise time on the reference line as a first position point (e.g. a point C in fig. 4), and defining a point of the sunset time on the reference line as a second position point (e.g. a point D in fig. 4), wherein the distance between the first position point and the second position point is in an increasing trend along with the increase of the time interval; the distance between the first location point and the second location point decreases with time interval as a decreasing trend. Specifically, a preset unit distance corresponding to a unit time on a reference line can be used for determining a product of a time interval and the unit distance as a target distance, and two position points with the interval of the reference line as the target distance are respectively used as sunrise time and sunset time.
Step S32, drawing a second-order bezier curve as the first curve on the first side of the reference line with the sunrise time as a first starting point, the sunset time as a first ending point, and the first target time as a first control point; the first side is above the horizon.
In this embodiment, the first side is specifically an upper side of the reference line. In other embodiments, the first side may also be the underside of the reference line or a user-specified side of the two sides of the reference line.
Specifically, positions corresponding to a first starting point, a first ending point and a first control point are determined in an area where the datum line is located, coordinates corresponding to the positions are obtained to serve as known values of a second-order Bezier curve function, a second-order Bezier curve (namely a first curve, such as a curve CDE in fig. 4) is drawn in an area above the datum line based on the second-order Bezier curve function with the known coordinates, a convex portion of the drawn first curve protrudes towards the upper side of the datum line, the starting point of the first curve is a mark point corresponding to the sunrise time on the datum line, the ending point of the first curve is a mark point corresponding to the sunset time on the datum line, the position corresponding to the first control point is located above the datum line, and a convex portion of the first curve passes through the position corresponding to the first control point.
In this embodiment, the first curve is drawn according to the above manner, so that the drawn first curve can be ensured to accurately reflect the related situation of the time when the sun rises above the horizon and the time when the sun is at the highest point.
Further, in this embodiment, the solar curve includes a second curve (such as the curve ABC and/or EFG in fig. 4), where the second curve characterizes a change of the position of the sun with respect to the horizon when the sun is below the horizon, and referring to fig. 6, step S20 includes:
step S22, determining a second target time, the sunrise time and the first time as second curve parameters corresponding to the second curve; the first time is earlier than the sunrise time, and the second target time is a second average value of the sunrise time and the first time;
the reference line is in particular a straight line extending in the transverse direction. Different points on the reference line may characterize different times. The positions of the sunrise time and the sunset time on the reference line differ depending on the time interval between the sunrise time and the sunset time. Defining a point of the sunrise time on the reference line as a first position point (e.g. a point C in fig. 4), and defining a point of the sunset time on the reference line as a second position point (e.g. a point D in fig. 4), wherein the distance between the first position point and the second position point is in an increasing trend along with the increase of the time interval; the distance between the first location point and the second location point decreases with time interval as a decreasing trend. Specifically, a preset unit distance corresponding to a unit time on a reference line can be used for determining a product of a time interval and the unit distance as a target distance, and two position points with the interval of the reference line as the target distance are respectively used as sunrise time and sunset time. In addition, a point of the first time on the reference line is defined as a third position point (e.g., point a in fig. 4), a point of the second time on the reference line is defined as a fourth position point (e.g., point G in fig. 4), the third position point and the fourth position point may be fixed points set in advance on the reference line, the unit distance may be determined based on the third position point and the fourth position point, and the unit time corresponding to the unit distance may be determined based on the interval length between the first time and the second time.
Step S23, determining a third target time, the sunset time and a second time as third curve parameters corresponding to the second curve; the second time is later than the sunset time, and the third target time is a third average value of the sunset time and the second time; the curve control parameters include the second curve parameter and the third curve parameter.
The first time and the second time may be fixed times set in advance, or may be times determined according to setting parameters input by a user. In this embodiment, the sunrise time and the sunset time belong to the same day, and the first time may be less than the second time, for example, the first time may be 0 point and the second time may be 24 points. In other embodiments, the sunrise time and the sunset time respectively belong to two adjacent days, and the first time and the second time may be the same time, for example, may each be 0 point between two adjacent days.
In this embodiment, the curve control parameters are determined according to the above steps S22 and S23, so that it is ensured that the drawn second curve can further accurately and intuitively reflect the position of the sun before and/or after sunrise with respect to the horizon at different times.

In this embodiment, the second side is specifically the underside of the reference line. In other embodiments, the first side may also be the upper side of the reference line or a user-specified side of the two sides of the reference line.
Specifically, the positions corresponding to the second starting point, the second ending point and the second control point are determined in the region where the datum line is located, the coordinates corresponding to the positions are obtained to serve as the known values of the second-order Bezier curve function, a second-order Bezier curve (namely, a first sub-curve, such as curve ABC in FIG. 4) is drawn in the region below the datum line based on the second-order Bezier curve function with the known coordinates, the convex part of the drawn first sub-curve protrudes towards the lower side of the datum line, the starting point of the first sub-curve is a mark point corresponding to the first time on the datum line, the ending point of the first sub-curve is a mark point corresponding to the sunset time on the datum line, the position corresponding to the second control point is located below the datum line, and the convex part of the first sub-curve passes through the position corresponding to the second control point.
