Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The embodiment of the invention makes two captured width of cloth pictures of close shot have bigger overlapping region by regulating the angle between two image unit camera lenses, and stereoscopic sensation is strong.
The angle adjusting mechanism that the binocular solid video camera that the embodiment of the invention provides comprises first image unit and second image unit and is used to regulate angle between described first image unit and the second image unit camera lens.
The 3D imaging system that the embodiment of the invention provides adopts above-mentioned binocular solid video camera.
Below in conjunction with specific embodiment realization of the present invention is described in detail.
As shown in Figure 1, the angle adjusting mechanism 13 that the binocular solid video camera that the embodiment of the invention provides comprises first image unit 11 and second image unit 12 and is used to regulate angle between this first image unit 11 and second image unit, 12 camera lenses, by the angle between these angle adjusting mechanism 13 adjusting first image units 11 and second image unit, 12 camera lenses, make two captured width of cloth pictures of close shot have bigger overlapping region, stereoscopic sensation is strong.
Particularly, this angle adjusting mechanism 13 comprises first adjutage 21, second adjutage 22, is located at first rotating shaft 31 of these first adjutage, 21 1 ends, is located at second rotating shaft 32 of these second adjutage, 22 1 ends and is located at this first adjutage 21 and the 3rd rotating shaft 33 of second adjutage, 22 other ends, first image unit 11 is located at first rotating shaft, 31, the second image units 12 is located at second rotating shaft 32.This angle adjusting mechanism 13 is simple in structure, easy operating.When the binocular solid video camera is taken, by first image unit 11 and second image unit, 12 picked-up first scene and second scenes, the center of this first scene and second scene is all overlapped, at this moment stereoeffect the best with the center of subject respectively.
This binocular solid video camera is taken scenery, when especially close shot is taken, first rotating shaft 31 and second rotating shaft 32 are rotated in opposite direction, angle between first image unit 11 and second image unit, 12 camera lenses is increased according to the focal length parameter or reduce, strengthened the stereoeffect of binocular solid video camera when taking the scene of the various depth of field, especially make two captured width of cloth pictures of close shot have bigger overlapping region, stereoscopic sensation is strong.Can adjust " going out screen " and " going into screen " effect of video by the angle of regulating between this first image unit 11 and second image unit, 12 camera lenses simultaneously, thereby make " going out screen " and " going into screen " best results, wherein " go out screen " is meant that scenery on the screen looks like outside screen and floating, " going into screen " on the contrary then.
For making the stereo base width cooperate focal length of camera to adjust automatically, by rotating the 3rd rotating shaft 33 first adjutage 21 and second adjutage 22 are rotated in opposite direction, the distance that can increase or reduce between first image unit 11 and second image unit, 12 camera lenses is the stereo base width.The embodiment of the invention drives adjutage by rotating shaft and smoothly rotates, and is more smooth and easy between the picture of adjacent twice picked-up of binocular solid video camera, avoided other regulative mode that picture is existed and paused, inadequately problem smoothly.
As one embodiment of the present of invention, angle adjusting mechanism 13 comprises first adjutage 21, second adjutage 22, first rotating shaft 31 of being located at first adjutage, 21 two ends and the 4th rotating shaft 34 and second rotating shaft 32 and the 5th rotating shaft 35 of being located at second adjutage, 22 two ends, first image unit 11 is located at this first rotating shaft 31, second image unit 12 is located at this second rotating shaft 32, as shown in Figure 2.Similarly, by rotating the 4th rotating shaft 34 and the 5th rotating shaft 35 first adjutage 21 and second adjutage 22 are rotated in opposite direction, the distance that can increase or reduce between first image unit 11 and second image unit, 12 camera lenses is the stereo base width.
As shown in Figure 3, this binocular solid video camera also has in order to control the control circuit that above-mentioned each rotating shaft is rotated, each rotating shaft is by corresponding with it motor driven, drive by first motor 51 as first rotating shaft 31, second rotating shaft 32 is driven by second motor 52, the 3rd rotating shaft 33 is driven by the 3rd motor 53, and the 4th rotating shaft 34 is driven by the 4th motor 54, and the 5th rotating shaft 35 is driven by the 5th motor 55.This control circuit comprises the focus controlling module 41 that is used to obtain the focal length parameter and according to the motor driving module 42 of this focal length calculation of parameter revolution parameter, focus controlling module 41 is electrically connected with first image unit 11 and second image unit 12 respectively, and motor driving module 42 is electrically connected with each motor respectively.After focus controlling module 41 receives the focal length of camera of user's manual adjustments, this focal length parameter is sent to motor driving module 42 and two image units; Image unit is according to this its camera parameter of focal length parameter adjustment; Motor driving module 42 goes out the rotational parameters of each motor according to this focal length calculation of parameter, and this rotational parameters is sent to each motor, thereby adjust two distance (being the stereo base width) and lens directions thereof between the image unit, reach the purpose that cooperates image unit to work as front focal length.
As shown in Figure 4, motor driving module 42 bases array function down drive each motor,
When f＞Lcsc (γ/2):
α＝90°，
β＝arccos(L/f)；
When f≤Lcsc (γ/2):
α＝arcsin(f·sin(γ/2)/L)，
