Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
In order to illustrate the technical means of the present invention, the following description is given by way of specific examples.
Example 1
As shown in fig. 1, a preferred embodiment of the live view method of the panoramic camera in the present embodiment includes the following steps.
S1, generating a longitude and latitude map mapping table according to the calibration parameters of each lens of the panoramic camera.
The panoramic camera in this embodiment includes at least two lenses (e.g., fisheye lenses or wide-angle lenses), and the partial fields of view of two adjacent lenses overlap to form a 360 ° panoramic field of view. The process of generating the longitude and latitude map mapping table in this embodiment is as follows: firstly, carrying out parameter calibration on real-time image data (video) shot by a panoramic camera to obtain calibration parameters, wherein the contents of the calibration parameters comprise the horizontal angle, the pitching angle, the spinning angle and the like of each lens; and then establishing a corresponding lens longitude and latitude table for each lens, and combining the longitude and latitude map table by combining the calibration parameters, so that each point in the space can find the coordinates and the weight of the real-time image data corresponding to at least one lens. The longitude and latitude map mapping table comprises an abscissa, an ordinate and a weight value, wherein the abscissa represents longitude of a spherical surface with the panoramic camera as a center, and the ordinate represents latitude of the spherical surface with the panoramic camera as the center. Wherein, the taking of the panoramic camera as the center comprises taking the geometric center of the overall shape of the panoramic camera or the gravity center of the panoramic camera as the center; in this embodiment, the geometric center of the focal points of the respective lenses of the panoramic camera may also be taken as the center, for example, when the number of lenses is two, the center is the midpoint of the connecting line of the two lens focal points; when the number of the lenses is three, the center is the gravity center of a triangle formed by three lens focuses; when the number of the lenses is four, the center is the intersection point of the diagonals of the quadrangle formed by the four lens focuses.
In the process of synthesizing a longitude and latitude map mapping table by using a lens longitude and latitude table, setting a weight for a point which is simultaneously located in images generated by two adjacent lenses according to a distance from the point to the center position of the images generated by the two lenses, wherein the closer the point to the center of the image generated by a certain lens, the larger the weight is, and the sum of the two weight values is 1, so as to effectively eliminate a splicing gap between the two lens images, for example, the weight of each lens to a certain point can be calculated in a weighted average manner, specifically, assuming that the distance from a certain point to a first lens is d1 and the distance from the certain point to a second lens is d2, the weight of the first lens is d 2/(d 1+ d 2), and the weight of the second lens is d 1/(d 1+ d 2); for a point in the image generated by only one shot, the weight of the shot at the point is set to be 1, so as to ensure the definition of the full-space image. In the above process, for a point located in an image generated by three or more lenses at the same time, two lenses with the smallest distance from the point to the center position of the image are selected, and different weights are set according to the distance between the point and the center position of the image generated by the two lenses.
And S2, calculating a first three-dimensional coordinate of an image displayed on a screen of a touch display screen of the panoramic camera.
In the line projection mode, assuming that the front of the panoramic camera is framed, the coordinates of the image displayed on the screen of the touch display screen are calculated as follows.
For a screen coordinate (i, j) of any point in the screen, a method for calculating a first three-dimensional coordinate (X1, Y1, Z1) of a display image thereof is: x1= tan (PI 0.5-fov PI/180 0.5) rayW 0.5; y1= (j-rayw0.5); z1= (i-rayH 0.5); here, rayW represents the width of the screen, rayH represents the height of the screen, fov represents the angle of view of the image displayed on the screen, and PI represents the circumferential ratio PI.
In this way, the first three-dimensional coordinates of all the points in the touch display screen of the panoramic camera can be obtained.
And S3, calculating a second three-dimensional coordinate according to the detected touch direction and angle of the touch display screen and the first three-dimensional coordinate.
In this step, a sliding state of a finger or a touch pen on a screen of the touch display screen is detected. In this embodiment, the left-right sliding on the screen indicates that the viewing angle swings on the yaw axis, the up-down sliding on the screen indicates that the viewing angle swings on the pitch axis, and since the sliding of the finger or the stylus on the screen of the touch display screen does not involve the turning of the screen, there is no roll axis swing, that is, the roll axis angle is kept at 0, the detected arc of the left-right sliding of the screen is represented by θ, and the detected arc of the up-down sliding of the screen is represented by Φ, then rot of the 3*3 rotation matrix can be calculated:
rot(0, 0) = cos(φ) * cos(θ);
rot(0, 1) = - sinf(θ);
rot(0, 2) = sinf(φ) * cosf(θ);
rot(1, 0) = cosf(φ) * sinf(θ);
rot(1, 1) = cosf(θ);
rot(1, 2) = sinf(φ) * sinf(θ);
rot(2, 0) = -sinf(φ);
rot(2, 1) = 0;
rot(2, 2) = cosf(φ);
for any one of the first three-dimensional coordinates (X1, Y1, Z1), the second three-dimensional coordinate (X2, Y2, Z2) of the display image is calculated by:
X2 =X1* rot(0, 0) + Y1 * rot(0, 1) +Z1 * rot(0, 2);
Y2= X1 * rot(1, 0) + Y1 * rot(1, 1) + Z1 * rot(1, 2);
Z2 =X1 * rot(2, 0) + Y1 * rot(2, 1) + Z1 * rot(2, 2);
substituting rot of 3*3 rotation matrix to obtain a calculation formula of a second three-dimensional coordinate (X2, Y2, Z2):
X2 =X1 * cos(φ) * cos(θ) + Y1* (- sinf(θ)) + Z1* sinf(φ) * cosf(θ);
Y2 =X1 *cosf(φ) * sinf(θ) + Y1 * cosf(θ) + Z1 * sinf(φ) * sinf(θ);
Z2 =X1 * (-sinf(φ)) + Y1 *0 +Z1 * cosf(φ)。
and S4, mapping the second three-dimensional coordinate into longitude and latitude.
For any second three-dimensional coordinate (X2, Y2, Z2), the longitude and latitude (fi, theta) calculation method comprises the following steps:
fi=atan2f(Y2，X2);
theta=PI * 0.5-atan2f(Z2，sqrt(X2*X2+Y2*Y2));
and when the calculated fi value is less than 0, adjusting the fi value to be 2 × PI-fi to ensure that the fi range is between 0 and 2PI. Where PI denotes the circumferential ratio π, and atan2f (a, b) is the arctangent of b/a in radians.
And S5, generating a real-time preview picture on the touch display screen according to the longitude and latitude, the longitude and latitude map mapping table and the acquired real-time image data of each lens.
Searching the coordinates and weighted values of the real-time image data (video) of the longitude and latitude map mapping table according to the longitude and latitude of the second three-dimensional coordinate obtained in the step S4; and copying the corresponding color value or the color value after weight calculation in the coordinate into a target picture to obtain a real-time preview picture, and displaying the real-time preview picture through a screen of a touch display screen.
According to the embodiment, the content to be displayed on the touch display screen of the panoramic camera only needs to be spliced, and the overall splicing of the pictures of all the lenses is not needed, so that the processing speed is high, and the method and the device are suitable for the real-time framing of the panoramic camera.

The panoramic camera further includes: the longitude and latitude map mapping table module is used for generating a longitude and latitude map mapping table according to the calibration parameters of each lens of the panoramic camera; the first calculation module is used for calculating a first three-dimensional coordinate of an image displayed on a screen of a touch display screen of the panoramic camera; the second calculation module is used for calculating a second three-dimensional coordinate according to the detected touch direction and angle of the touch display screen and the first three-dimensional coordinate; the mapping module is used for mapping the second three-dimensional coordinate into longitude and latitude; and the preview picture module is used for generating a real-time preview picture on the touch display screen according to the longitude and latitude, the longitude and latitude map mapping table and the acquired real-time image data of each lens.
