Example one

Fig. 1 is a flowchart of an image capturing method according to an embodiment of the present disclosure, where the present disclosure is applicable to a scene in which an image of an object that a user wishes to present conforms to an imaging habit of an eye of the user, and the method may be executed by an image capturing apparatus according to an embodiment of the present disclosure, where the apparatus may be implemented by software and/or hardware, and may be integrated in an electronic device, and the electronic device may be an intelligent device such as a computer or a tablet computer.

As shown in fig. 1, the image acquisition method includes:

and S110, determining the difference value of the acquisition angles when two adjacent images are acquired according to the preset acquisition angles and the preset number of images.

The preset acquisition angle refers to the angle of an object to be shot, and can be set according to the requirements of a user.

Illustratively, as shown in fig. 2, fig. 2 is a schematic diagram of a camera system. The object to be shot is placed on the rotary table, and the image collector is located on one side of the rotary table and used for collecting images of the object to be shot on the rotary table. An object to be shot is placed on the middle rotary table, and the rotary table rotates at a certain rotating speed. The image collector is fixed at a position away from the object to be photographed by a certain distance, and the object to be photographed rotating on the turntable is photographed by using the shutter, wherein the interval time for controlling the image collector to trigger the shutter is the collection interval time, which may be 1s, 2s or other time, which is not limited in this embodiment. The electronic equipment is used for controlling the shooting of the image collector and the rotating speed of the rotary table. Optionally, the preset collection angle may be 360 degrees, 270 degrees, and the like, and the angle may be set according to the requirement of the user. If the preset collection angle is 360 degrees, the rotating platform rotates for a circle, and in the process of rotating for a circle, the image collector triggers the shutter at certain time intervals to shoot the rotating object to be shot. The present embodiment does not limit the position relationship between the image collector, the turntable, and the electronic device.

The preset image quantity refers to the actual quantity of collected images obtained after the rotation angle of an object to be shot on the rotary table reaches a preset collection angle.

For example, if the preset capturing angle is 360 degrees, the number of images captured by the image capturing device after the object to be captured rotates one circle is the preset number of images.

In this embodiment, optionally, the number of preset images may be determined according to a distance between the image acquirer and the object to be photographed, a pupil distance between two eyes, and a preset acquisition angle.

Illustratively, as shown in FIG. 3, FIG. 3 is a schematic view of a human eye simulated for viewing a rotating object. Wherein the left eye or the right eye represents an image collector, the eye distance between the left eye and the right eye is d, and the point B is the midpoint of a connecting line between the left eye and the right eye. The point a represents an object to be photographed, and the circle represents a turn table on which the object to be photographed is placed. The distance between the point A and the image collector is S. The included angle between the left eye and the two connecting lines of the point A and the right eye is the left-right eye parallax angle, and theta represents half of the left-right eye parallax angle and is called half left-right eye parallax angle. Firstly, calculating to obtain a half left-right eye parallax angle theta according to the eye distance and the distance S between the point A and the image collector, wherein the left-right eye parallax angle is 2 theta. When the rotation angle of the object to be shot is equal to the left-right eye parallax angle, the image collector presses the shutter once to obtain one image, when the object to be shot is rotated by the preset collection angle, the theoretical number of the images can be obtained, and the angle difference between the collected images shot at every two adjacent shutters is equal to the left-right eye parallax angle. The preset number of images may be determined based on a theoretical number of images, and the preset number of images may be greater than or equal to the theoretical number of images.

The acquisition angle difference is the rotation angle of the object to be shot between two adjacent shutter pressing times of the actually set image acquisition device. Since the number of the preset images is greater than or equal to the number of the theoretical images, that is, the number of the preset images may be different from the number of the theoretical images, the difference value of the collection angle needs to be calculated according to the preset collection angle and the number of the preset images.

For example, the acquisition interval time may be preset, and the target rotation speed of the turntable may be determined according to the acquisition angle difference and the acquisition interval time, so that the angle that the turntable rotates at the target rotation speed is consistent with the acquisition angle difference in the acquisition interval time. Illustratively, the target rotating speed r of the rotary table is calculated according to the acquisition angle difference value alpha and the acquisition interval time T, so that the rotating angle of the rotary table in the time T is alpha.

Or the target rotating speed can be preset, and the acquisition interval time is determined according to the acquisition angle difference and the target rotating speed of the rotary table, so that the rotating angle of the rotary table at the target rotating speed is consistent with the acquisition angle difference in the acquisition interval time; illustratively, the acquisition interval time T is calculated according to the acquisition angle difference value α and the target rotation speed r of the turntable, so that the turntable rotates by the angle α within the time T.

In this embodiment, the image collector may be a video camera, a scanner, or other devices with a photographing function, such as a mobile phone and a tablet computer, which is not limited in this embodiment.

The acquisition interval time of the image collector is the time interval between the image collector and the adjacent two images, and the acquisition interval time of the image collector corresponds to the acquisition angle difference.

For example, if the acquisition angle difference is α, the time of the first image acquired by the image is T, and the time of the second image acquired by the image is T + T, the time interval between the two acquisitions is T, and the rotation angle of the object to be photographed on the rotating table is equal to the acquisition angle difference α within the time T.

Wherein the target rotating speed of the rotary table is the number of turns in unit time.

And S130, controlling the rotary table to rotate based on the target rotating speed, and controlling the image collector to continuously collect images of the object to be shot according to the collection interval time to obtain collected images with preset image quantity.

Illustratively, a technician inputs the eye distance d of a user and the distance S between an object to be shot and an image collector into electronic equipment, and calculates a half left-right eye parallax angle theta; inputting the set preset acquisition angle into the electronic equipment, and calculating an acquisition angle difference value alpha when two adjacent images are acquired by the electronic equipment according to the preset acquisition angle and the half left-right eye parallax angle theta; inputting the acquisition interval time T of the image acquisition device into the electronic equipment, and calculating the target rotating speed of the rotary table by the electronic equipment according to the acquisition interval time T and the acquisition angle difference alpha; and the electronic equipment controls the rotary table to rotate at a target rotating speed according to the calculation result, and simultaneously controls the image collector to collect the images of the object to be shot rotating on the rotary table, so as to finally obtain the collected images with the preset number of images. In this embodiment, the electronic device may be a device, such as a computer, for calculating a target rotation speed of the turntable and controlling the rotation of the turntable.

optionally, the acquisition interval time may be preset, and the target rotation speed of the turntable is determined according to the acquisition angle difference and the acquisition interval time, so that the angle of the turntable rotating at the target rotation speed is consistent with the acquisition angle difference within the acquisition interval time. The acquisition time required for the acquisition angle to reach the preset acquisition angle can be determined according to the following formula:

wherein T 'is the acquisition time required for the acquisition angle to reach the preset acquisition angle, theta' is the preset acquisition angle, alpha is the acquisition angle difference, and T is the acquisition interval time.

When the target images are spliced to obtain the visual angle images, attention needs to be paid to the splicing sequence of the target images so as to meet the visual effect of human eyes. For example, if the turntable rotates clockwise when viewed from a top view angle, the turntable rotates from right to left relative to the image collector, and the target image a is collected first and then the target image b is collected, the target image a is taken as a viewing image in a left eye view angle, and the target image b is taken as a viewing image in a right eye view angle, that is, the target image a is placed on the left side of the target image b for splicing. If the turntable rotates anticlockwise under the overlooking angle, the turntable rotates from left to right relative to the image collector to collect the target image a firstly and collect the target image b secondly, the target image a is used as a watching image under the right eye viewing angle, the target image b is used as a watching image under the left eye viewing angle, and the target image b is placed on the left side of the target image a for splicing.

Then, the 9 images are horizontally and vertically reduced to 1/3, and finally spliced into 9 grid pictures, and the splicing effect picture is shown in fig. 6.
