Detailed Description
The embodiment of the invention provides a panoramic image acquisition method and a panoramic camera, which are used for improving the splicing quality of panoramic images.
In order to clearly understand the panoramic image capturing method and the panoramic camera provided by the embodiment of the present invention, some technical terms involved in the method and the panoramic camera are described in detail below.
1) A panoramic image.
A PANORAMIC image (or PANORAMA, english name) generally refers to an image photographed over a normal effective visual angle of both eyes (about 90 degrees horizontally, 70 degrees vertically) or over a visual angle including the residual light of both eyes (about 180 degrees horizontally, 90 degrees vertically), or even over a full scene range of 360 degrees.
2) The jelly effect.
The formation of the jelly effect is determined by the characteristics of the camera itself, and most of the cameras using a Complementary Metal Oxide Semiconductor (CMOS) sensor use a rolling shutter, which takes pictures by exposing an image sensor line by line.
The exposure process of the CMOS sensor can be roughly understood as power-off (electrical signal clearing) -exposure-power-on (light source converting electrical signal imaging). Moreover, the exposure process of the CMOS sensor is performed in a line-by-line or column-by-column scanning manner, and as shown in fig. 1, this operation mode of the CMOS sensor is called a rolling shutter operation mode.
When a camera using a CMOS sensor uses a rolling shutter, if an object to be photographed moves at a high speed or vibrates at a high speed with respect to the camera, the image is photographed using the rolling shutter, and the scanning speed of the CMOS sensor is insufficient, so that the photographing result may have "tilt", "sway" or "partial exposure", that is, a jelly effect. For example, as shown in fig. 2, a person is shot by a camera, and the person moves rapidly from right to left along a moving direction 201, and at this time, the exposure process of the CMOS sensor of the camera is performed in a manner of scanning line by line along a scanning direction 202 from top to bottom. Due to the relative movement of the person and the camera, a jelly effect is generated, as shown in fig. 3, when the imaging of the light sensed by the CMOS sensor is tilted.
The panoramic image acquisition method is applied to the panoramic camera, the panoramic camera is provided with at least two cameras, and after the cameras acquire images, the images acquired by the cameras are spliced to obtain the panoramic image.
Fig. 4 is a schematic structural diagram of a panoramic camera according to an embodiment of the present invention. As shown in fig. 4, the panoramic camera is provided with four cameras 401. The panoramic camera can acquire images through the four cameras respectively to obtain four images. Then, the four images are spliced on the panoramic camera or other equipment, and the panoramic image can be obtained.
The panoramic image acquisition method of the embodiment of the invention can be applied to the panoramic camera shown in FIG. 4.
It should be understood that the panoramic camera shown in fig. 4 is only an exemplary camera and does not specifically limit the panoramic camera according to the embodiment of the present invention.
Fig. 5 is a flowchart of a panoramic image acquisition method according to an embodiment of the present invention. The panoramic image acquisition method is applied to a panoramic camera, and the panoramic camera is provided with a first camera and a second camera.
Referring to fig. 5, the panoramic image capturing method according to the embodiment of the present invention includes the following steps.
Step 501: and controlling a photosensitive chip of the first camera to scan along a first direction so as to obtain a first image.
The panoramic image acquisition method is applied to the panoramic camera, and the panoramic camera can respectively acquire images to be spliced through the first camera and the second camera arranged on the panoramic camera.
As shown in fig. 6, the first camera includes a photosensitive chip 601, and an image can be captured by the photosensitive chip 601. Specifically, the panoramic camera controls the photosensitive chip 601 of the first camera to scan along the first direction 602, so that the first camera captures a first image.
Step 502: and controlling the photosensitive chip of the second camera to scan along the second direction so as to obtain a second image.
The first direction and the second direction are opposite, specifically, the first direction and the second direction are opposite directions, or the first direction and the second direction are opposite directions. The first direction faces or deviates from the photosensitive chip of the second camera, and the second direction faces or deviates from the photosensitive chip of the first camera. The photosensitive chip of the first camera and the photosensitive chip of the second camera are CMOS image sensors.
As shown in fig. 6, the second camera includes a photosensitive chip 603, and an image can be captured by the photosensitive chip 603. Specifically, the panoramic camera controls the photosensitive chip 603 of the second camera to scan along the second direction 604, so that the second camera captures a second image.
In the embodiment of the invention, the photosensitive chip of the first camera and the photosensitive chip of the second camera are CMOS image sensors, the photosensitive chip of the first camera and the photosensitive chip of the second camera are provided with pixel points arranged in an array, and the photosensitive chips scan line by line or column by column according to a specific arrangement mode during specific light sensing.
The first direction is a direction in which the photosensitive chip of the first camera scans line by line or row by row sequentially, and the second direction is a direction in which the photosensitive chip of the second camera scans line by row or row by row sequentially.
In the embodiment of the invention, the first direction faces or deviates from the photosensitive chip of the second camera, and the second direction faces or deviates from the photosensitive chip of the first camera. And the first direction and the second direction are opposite, so that, in one example, as shown in fig. 6, the first direction and the second direction are two opposite directions, the first direction is a direction from the photosensitive chip of the first camera to the photosensitive chip of the second camera, and the second direction is a direction from the photosensitive chip of the second camera to the photosensitive chip of the first camera. In another example, the first direction and the second direction are opposite directions, the first direction is a direction from the photosensitive chip of the second camera to the photosensitive chip of the first camera, and the second direction is a direction from the photosensitive chip of the first camera to the photosensitive chip of the second camera.
Because the sensitization chip of first camera and the sensitization chip of second camera are CMOS image sensor to when being shot the relative motion of object relatively panoramic camera high speed, the first image that first camera was gathered and the second image that the second camera was gathered produce the jelly effect easily.
In the embodiment of the present invention, if the object moves in the direction perpendicular to the first direction and the second direction with respect to the panoramic camera, the shape of the object is closer to the adjacent position between the first image and the second image because the first direction is opposite to the second direction.
Specifically, when the first direction and the second direction are opposite directions, the photosensitive chip of the first camera scans to a position close to the photosensitive chip of the second camera along the first direction, and the photosensitive chip of the second camera also scans to a position close to the photosensitive chip of the first camera along the second direction, so that the information of the object to be photographed, which is collected by the photosensitive chip of the first camera at the position close to the photosensitive chip of the second camera and the photosensitive chip of the second camera at the position close to the photosensitive chip of the first camera, is the same or close to each other.
When the first direction and the second direction are opposite to each other, the photosensitive chip of the first camera starts scanning from the position close to the photosensitive chip of the second camera along the first direction, and the photosensitive chip of the second camera starts scanning from the position close to the photosensitive chip of the first camera along the second direction, so that the information of the shot object collected by the photosensitive chip of the first camera at the position close to the photosensitive chip of the second camera is the same as or close to the information of the shot object collected by the photosensitive chip of the second camera at the position close to the photosensitive chip of the first camera.
In the two situations, the information of the shot object is the same or close to the adjacent position of the first image and the second image, so that after the first image and the second image are spliced, the splicing gap is not obvious at the adjacent position of the first image and the second image, the first image and the second image are excessively smooth at the adjacent position, and the splicing quality is improved.
Step 503: and splicing the first image and the second image to obtain a panoramic image.
After the first image and the second image are acquired, the first image and the second image can be stitched on the panoramic camera to obtain a panoramic image. Or, the other device acquires the first image and the second image sent by the panoramic camera, and then splices the first image and the second image to obtain the panoramic image.
The panoramic image may be composed of the first image and the second image, or the first image and the second image are partial images in the panoramic image. Wherein, in the panoramic image, the first image and the second image are connected.
The following describes advantageous effects of the panoramic image capturing method according to the embodiment of the present invention with a specific example.
Referring to fig. 7 to 9, in the panoramic camera shown in fig. 4, the panoramic image capturing method according to the embodiment of the present invention is performed. When the shot object and the panoramic camera do not move relatively, the images collected by the panoramic camera do not have the freezing effect, the images collected by the 4 cameras are spliced by the panoramic camera to obtain the panoramic image shown in fig. 7, wherein fig. 7 is the panoramic image after plane projection. If the object to be shot moves highly relative to the panoramic camera, for example, moves at a high speed along the vertical direction, at this time, the images collected by the cameras of the panoramic camera can generate a jelly effect, and if the scanning directions of the photosensitive chips of the cameras of the panoramic camera are the same, at this time, after the images collected by the cameras are spliced, the splicing gaps among different images are large, so that the obtained panoramic image has a poor effect. For example, 4 cameras of the panoramic camera are arranged along a ring, the ring is parallel to the horizontal plane, the object to be photographed moves upward relative to the panoramic camera along the vertical direction, and at this time, if the scanning directions of the photosensitive chips of the cameras of the panoramic camera are the same and all are from left to right, the images collected by the cameras are subjected to panoramic stitching, and the obtained panoramic image is as shown in fig. 8. As can be seen from fig. 8, in the panoramic image, the image difference at the stitching position of the images acquired by each camera is large, so that the stitching gap is obvious.
If the panoramic image acquisition method provided by the embodiment of the invention is used, the images acquired by the camera of the panoramic camera still generate the jelly effect, but the image information of the shot object at the adjacent positions among different images is relatively similar or identical. For example, 4 cameras of a panoramic camera are arranged along a ring, the ring is parallel to a horizontal plane, a photographed object moves upward relative to the panoramic camera along a vertical direction, at this time, the scanning direction of the photosensitive chip of each camera of the panoramic camera is as shown in fig. 6, the scanning direction of the photosensitive chip of the adjacent camera is opposite, at this time, images collected by each camera are spliced, and a panoramic image is obtained as shown in fig. 9. In the panoramic image, images at the splicing positions of the images acquired by the cameras can be free of difference, so that the images at the splicing positions are identical, splicing gaps are not obvious, and the splicing quality of the panoramic image is improved.
Optionally, a length of the photosensitive chip of the first camera along the first direction is smaller than a length along a direction perpendicular to the first direction. The length of the photosensitive chip of the second camera along the second direction is smaller than the length of the photosensitive chip along the direction perpendicular to the second direction. Because the length of the photosensitive chip is in direct proportion to the pixels of the photosensitive chip, the photosensitive chip of the first camera in the direction perpendicular to the first direction can acquire more image information, and the photosensitive chip of the second camera in the direction perpendicular to the second direction can acquire more image information. And along the first direction or along the second direction, the first image and the second image are spliced to realize expansion. Therefore, more image information can be acquired through the photosensitive chip of the first camera and the photosensitive chip of the second camera.
It should be understood that the panoramic camera according to the embodiment of the present invention may be provided with two or more cameras. In some specific embodiments, the panoramic camera of embodiments of the present invention is provided with a plurality of cameras, such as 3, 4, or more cameras. The first camera and the second camera belong to two of the plurality of cameras. The plurality of cameras are arranged in a surrounding mode in sequence. The scanning directions of the photosensitive chips of the adjacent cameras in the plurality of cameras are opposite. In this way, the directions indicated by the scanning directions of the photosensitive chips of the different cameras are alternately arranged. The photosensitive chips of the cameras are CMOS image sensors. However, by using the method of the embodiment of the invention, after the images acquired by different cameras are spliced, the images at the splicing positions can have no difference, so that the images at the splicing positions are identical, the splicing gaps are not obvious, and the splicing effect of the panoramic image is improved.
In order to further improve the similarity between adjacent positions of different images and thus improve the stitching effect, optionally, the step of controlling the photosensitive chip of the first camera to scan along the first direction to obtain the first image specifically includes: when a shooting instruction is acquired, the photosensitive chip of the first camera is controlled to scan along the first direction, so that a first image is obtained.
And controlling the photosensitive chip of the second camera to scan along the second direction to obtain a second image, wherein the step of controlling the photosensitive chip of the second camera to scan along the second direction specifically comprises the following steps: and when a shooting instruction is acquired, controlling a photosensitive chip of the second camera to scan along a second direction so as to obtain a second image.
Therefore, under the triggering of the shooting instruction, the photosensitive chip of the first camera and the photosensitive chip of the second camera scan simultaneously and reach the opposite side of the photosensitive chip simultaneously, so that the information of the shot object collected by the photosensitive chip of the first camera at the position close to the photosensitive chip of the second camera and the information of the shot object collected by the photosensitive chip of the second camera at the position close to the photosensitive chip of the first camera are closer, in other words, the image information of the first image and the image information of the second image at the adjacent position are closer, and therefore after the first image and the second image are spliced, the splicing gap of the first image and the second image is more unobvious, and the splicing quality of the panoramic image is better.
It should be understood that there are various specific implementations of the panoramic camera acquiring the shooting instruction, for example, a user triggers a shooting button on the panoramic camera; or the panoramic camera is started to automatically generate a shooting instruction.
In order to further improve the similarity between adjacent positions of different images, so as to improve the stitching effect, optionally, when the shooting instruction is obtained, the step of controlling the photosensitive chip of the first camera to scan along the first direction to obtain the first image specifically includes: when a shooting instruction is acquired, a photosensitive chip of the first camera is controlled to scan along a first direction at a target speed to obtain a first image.
The step of controlling the photosensitive chip of the second camera to scan along the second direction when the shooting instruction is obtained to obtain the second image specifically includes: and when a shooting instruction is acquired, controlling a photosensitive chip of the second camera to scan along a second direction at a target speed to obtain a second image.
Therefore, the photosensitive chip of the first camera and the photosensitive chip of the second camera scan simultaneously when acquiring the shooting instruction, the scanning speed is the same, but the scanning directions are opposite, and the image information of the acquired first image and the acquired second image at the adjacent positions is more similar, so that smooth splicing is facilitated, and the splicing effect of the panoramic image is improved.
In summary, the panoramic image capturing method of the embodiment of the present invention is applied to a panoramic camera, and the panoramic camera is provided with a first camera and a second camera. In the panoramic image acquisition method provided by the embodiment of the invention, the photosensitive chip of the first camera is controlled to scan along the first direction so as to obtain the first image. And controlling the photosensitive chip of the second camera to scan along the second direction to obtain a second image. Then, the first image and the second image are spliced to obtain a panoramic image. The photosensitive chip of the first camera and the photosensitive chip of the second camera are CMOS image sensors, and when a shot object and the panoramic camera move relatively at a high speed, the first image and the second image are easy to generate a jelly effect. However, in the panoramic image capturing method according to the embodiment of the present invention, the first direction is opposite to the second direction, the first direction faces or deviates from the photosensitive chip of the second camera, and the second direction faces or deviates from the photosensitive chip of the first camera. Therefore, the image information of the shot object is approximate at the adjacent position of the first image and the second image, namely the splicing position, and the quality of splicing the panoramic image is improved.
