Embodiment 1

[0110] Such as figure 1 shown. The surrounding mixed light field imaging device is composed of a controller 100 , a light field camera 110 , a rotating platform 120 and a conventional camera 130 . The light field camera 110 and the traditional camera 130 are placed at both ends of the rotating platform 120 and installed at a fixed angle on the same horizontal plane. A rotating device is installed in the rotating table 120, which can be a motor, a manual crank or other equipment that can rotate the rotating table, and can rotate 360°. The controller 100 is used to control the start and stop of the rotation of the rotating table 120 , and the shooting of the light field camera 110 and the conventional camera 130 .

[0111] The controller 100 is used to select the rotational speed of the rotary table 120 , and to calibrate the shooting parameters of the light field camera 110 and the traditional camera 130 . The controller 100 starts the rotating device in the rotating table 1...

Embodiment 2

[0114] Such as figure 2 As shown, numeral 200 is a traditional camera-Sony DSX T77, numeral 210 is a Lytroillum light field camera, numeral 220 is a circular platform, numeral 230 is a base, and numeral 240 is a rotating motor power cord.

[0115] The reference number 200 is a traditional camera-Sony DSX T77 and the reference number 210 is a Lytroillum light field camera respectively fixed on the two edges of the circular platform 220, the lenses of the two cameras are all facing outwards, and the connecting line of the two cameras passes through the center of the platform 220 point, the two cameras are placed symmetrically with respect to the center point, and the angle between the two cameras is 180°. A motor capable of 360° rotation is placed in the base 230 to drive the platform 220 to rotate.

[0116] The two cameras are rotatable along the horizontal plane of the platform circle 220, and collect synchronously when rotating, and the range of the collection field of view...

Embodiment 3

[0120] Such as Figure 4 As shown, the label 300 is the traditional camera Sony DSX T77, the label 310 is the device for fixing the traditional camera Sony DSXT77, the label 320 is the Lytroillum light field camera, the label 330 is the device for fixing the Lytroillum light field camera, and the label 340 is for use For the platform on which objects are placed, numeral 350 is a device for fixing the platform, numeral 360 is a rotating platform, numeral 370 is a base of the rotating platform, and numeral 380 is a dell desktop computer.

[0121] On the computer, the label 300 is the traditional camera Sony DSX T77 and the label 320 is the system parameters of the Lytroillum light field camera (including the number of pictures taken, the time of taking pictures, the speed of taking pictures, the exposure time, etc.). The object is placed on the object platform 340, and the rotating platform The motor in the base 370 starts to work, driving the rotating table 360 ​​to start to ro...

Abstract

The invention provides a surrounding type hybrid optical field imaging device and method. The method includes parameter calibration of a surrounding type hybrid optical field imaging device, and also includes using the surrounding type hybrid optical field imaging device to obtain images, fusing the obtained images, rendering the obtained images, and generating a final image. The surrounding type hybrid optical field imaging device and method provided by the invention combine a parameter calibration means with the depth capability of an optical field camera and a high-definition image of a traditional camera, and can obtain a high-quality scene three-dimensional image.

Description

technical field [0001] The present application relates to the field of image capturing and processing, and in particular to a surrounding mixed light field imaging device and method. Background technique [0002] Three-dimensional panoramic imaging technology is a new market hotspot that has exploded in recent years, especially in the fields of VR / AR, somatosensory games, and social networking, which have great market prospects. At present, some panoramic imaging devices have appeared on the market. For example, the Surround360 produced by Facebook is composed of 17 cameras, including a disc surrounded by 14 wide-angle cameras, a fisheye camera on the top and two cameras on the bottom. Network software that can shoot up to 8K pixel video; Samsung's Project Beyond looks like a flying saucer. 16 cameras are installed in a ring around the "flying saucer", and each two cameras are responsible for shooting within a 45-degree angle range. At the center of the camera is a powerfu...
