Abstract
The invention provides a laser positioning type panoramic photography tripod head, which comprises a rotating base and a camera installation adjusting bracket. The panoramic photography tripod head also comprises a laser positioning transmitting device, wherein the laser positioning transmitting device comprises a battery, a power switch and a laser head; and the laser head is positioned on the central axis of the rotating base. When the panoramic photography tripod head works, a laser beam emitting from the central axis of the rotating base directly irradiates onto a lens along an axial line, and the position of a node of the lens can be adjusted to the laser beam emitting from the rotating central axis conveniently and intuitionally through adjusting the position of the camera on the camera installation adjusting bracket, thereby accurately determining that whether the node is in the rotating center or not, and ensuring that a panoramically photographed photo can be perfect during software splicing.
Description
Technical field
The present invention relates to a kind of panoramic shooting head, particularly relate to a kind of 360 ° of panoramic shooting heads that require accurately to determine node location.
Background technology
In the ordinary course of things, full shot is meant rotation camera when taking, and the scene in 360 ° of spaces on every side center on a kind of camera style of shooting.Because the progress of computer software science and technology, full shot can utilize camera that 360 ° of scenes are on every side synthesized by various panoramas splicing softwares then around taking multiple pictures, can obtain annular or spherical panoramic pictures.And be used for the pan and tilt head of full shot, guarantee that exactly each photo of taking can both be spliced into the hardware device of panoramic pictures smoothly by software.The main points of taking with pan and tilt head are that the node location with camera lens is fixed on the central axis of camera rotation accurately, camera is the central shaft rotation with the central axis at the node place of camera lens during shooting, just guaranteed that opening photo with captured each of a full shot all is on same node location, thereby also guaranteed the success of software spliced panoramic picture.
" node " of camera lens (Nodal point) is meant the scenery 4 that the camera lens outside is upright and it is by the point of crossing between the image 5 of camera lens arrival egative film formation handstand.For example the image of one tree stands upside down by the imaging that camera lens arrives egative film, and that point of crossing between the image of its upright image and handstand is exactly a node 3, referring to Fig. 1.Because each camera lens all is inequality at the node location of different focal, so want by experiment the node location of each burnt section of used camera lens to be found out and noted in advance, when carrying out pan-shot, just can determine node location according to prior mark easily.If without pan and tilt head, camera is directly installed on the tripod, camera is the center rotation with the installation site of fuselage bottom just so, the node location of camera lens is constantly change when taking so, the photo of rotation shooting is when splicing like this, junction between the photo will be to irregular, particularly can be quite obvious when the shooting in closely little space.
The effect of pan and tilt head is exactly that node location with the used camera lens of pan-shot is fixed on the rotation center axis of camera accurately.But, when using existing pan and tilt head that node location is adjusted, generally all be with the mode of range estimation, mainly rely on operator's experience to control, operating difficulties, precision is not high when causing spliced panoramic figure, often can't satisfy request for utilization.
Summary of the invention
The purpose of this invention is to provide a kind of location of laser beam that utilizes and carry out the panoramic shooting head that node location is regulated, promptly be radiated on the camera lens conveniently to determine intuitively whether the position of node is adjusted correctly by emission of lasering beam, simple to operate, improved the splicing precision of panoramic pictures greatly.
Technical scheme of the present invention can realize by following technical measures, a kind of laser positioning type panoramic shooting head, comprise rotating base and camera installation adjusting bracket, it is characterized in that also comprising the laser positioning emitter, described laser positioning emitter comprises battery, power switch and laser head, and described laser head is positioned on the central axis of described rotating base.
When panoramic shooting head of the present invention is worked, the laser beam of sending from the central axis of rotating base shines directly on the camera lens along axis, by adjusting the position of camera on camera installation adjusting bracket, can make things convenient for intuitively node location with this camera lens to be adjusted on the laser beam of sending from the rotation center axis, thereby can determine node accurately whether on rotation center, perfect when software splices with the photo that guarantees pan-shot.
The present invention can do following improvement, and described laser positioning emitter can be for built-in, and promptly described laser positioning emitter can be fixed on the described rotating base by setting-in.The position of the corresponding laser head of described rotating base upper surface can also be provided with transmitting aperture, and the light beam that this transmitting aperture can make laser head send upwards penetrates smoothly along the central axis of rotating base.During use, only need open the power switch of laser positioning emitter, just can regulate the node location of camera lens.
Laser positioning emitter of the present invention can also be external, and during use, the laser head of laser positioning emitter is arranged on the upper surface of rotating base, and is positioned at the central axis place of rotating base.The laser positioning emitter of external and rotating base are separate in essence, should use more flexiblely, and its principle of work is identical with built-in laser positioning emitter.
Compared with prior art, advantage of the present invention is:
(1) laser positioning type panoramic shooting head of the present invention, can carry out the node location adjustment accurately, intuitively, easily, the node location that is about to camera lens is accurately determined on the central axis that the camera rotation is taken, thereby guaranteed full shot picture perfect when software splices, thoroughly solved existing panoramic shooting head when adjusting node by range estimation, by experience, problem accurately inadequately.
(2) laser positioning type panoramic shooting head of the present invention, its laser positioning emitter only needs simple low-voltage, low light level Shu Faguang, need not laser receiver, laser beam is the in-plant camera lens side that is radiated at directly, eyes can be observed and get final product, and principle is simple, cost of manufacture is low, be convenient to realization.
(3) laser positioning type panoramic shooting head of the present invention, the form of laser positioning emitter can be diversified, to be applicable to different conditions of work: the laser positioning emitter can be built-in, and its advantage is that the location is accurate, simple to operate, easy to carry; The laser positioning emitter can also be an external, and advantage is a highly versatile, can be used in above the different pan and tilt heads, and several pan and tilt heads can also a shared laser positioning emitter.
