Description

The projecting method and the device that have the view data Dynamic matching
Prior art
The present invention relates to a kind ofly through projector image or view data projected the method on the projecting plane, the projection centre axis of wherein confirming distance and/or projector between at least one point on projector and projecting plane is given control and/or regulon with respect to the orientation on projecting plane or position and with the information conveyance of relevant distance of confirming like this and/or position.When projection, view data is projected on the suitable projecting plane through light, for example screen, and wall, screen or display, known in slide projector, elevated projecting or video projector as for example.The present invention relates to a kind of device corresponding to this method in addition.
In this method, except the projection of image, also will confirm distance and/or relative direction between projector and the projecting plane, this method for example is used for revising automatically and/or automatic focusing will project the image on the projecting plane.If the projection centre axis of projector and projecting plane are not mutual vertical orientations, so always hope correction image automatically.This moment, the distortion of the projects images that the beholder can see was revised by means of Keystone revised law or trapezoidal revised law usually.In this case, the distortion of appearance is wanted a kind of artificial reverse distortion that produces of image projected to offset.
Measuring the inclination angle of projector with Keystone revised law or trapezoidal revised law work obliquity sensor commonly used often, and in DE4204821A1, disclosing a kind of method of coming correction image through the distance between measuring projector and the projecting plane with respect to a surface level.Herein, view data projects on the tunnel wall face from train, and two distance meters that wherein are positioned on the different vertically height and positions of train are measured the distance of wall to the tunnel separately.Go out the tunnel wall with respect to the inclination angle that projector projection centre axis aboard is installed by these two distance calculation, automatically revise according to the inclination angle of calculating so then and want image projected.But the flexibility of tunnel in view field must be known and be constant on travel route, so that this correction can produce spendable result.But under all situations of image correction, what be affected is not the content of image, and is the geometric configuration of image all the time.
Just need be when the distance between projector and projecting plane is changed to wanting the image projected focusing.Therefore the method for being carried out automatic focusing by image projected especially is applied on different places, use termly, that is always is arranged in the last portable projector of new distance with respect to the projecting plane.The method of this automatic focusing divides a plurality of steps to implement.In first step, the distance between measuring projector and the projecting plane is for example measured through the sensor on the projector.In second step, project the pinpointed focus of the image on the projecting plane and follow automatically corresponding this focal length of adjustment according to measured distance calculation.Therefore the optical system of projector is adjusted in the case, but does not influence the content of view data or image.
This automatic focusing method is very ripe and can accurately regulates by image projected on fast and reliable ground.But this method can not be used for surpassing the adjustment beyond the focal length.
Because projector is designed to be more and more littler and is more convenient for thus carrying, but some new usable range often occur, in these usable range, only focus or image correction also is not enough to show best the image projected information of wanting.Therefore, can exceed focusing and revise beyond to image parameter or to be changed by the image projected data possibly be to be worth hoping.
Disclosure of an invention
The purpose of this invention is to provide a kind of improved method that starts said type, this method can be optimized projection and especially improves by the identifiability of image projected data with simple mode.
This purpose solves according to the described method of claim 1 through a kind of.
The present invention based on design be; Make at least one pictorial element of the view data that will project on the projecting plane by control module, but preferred a plurality of pictorial elements automatically with relevant projector and projecting plane between distance information and/or be complementary with the information of relevant projector with respect to the position on projecting plane.
Main basic thought of the present invention is; Not only utilize to the measurement of the distance between projector and the projecting plane or to the relative orientation between projector and the projecting plane confirm to come only to revise by the shape of image projected or through the adjustment focal length come focusedimage, and utilize the distance of measuring to influence to want the image projected data or by each pictorial element of image projected data itself.Therefore depended on the measuring distance between projector and projecting plane or depend on the determined orientation of projector this moment by the image projected data with respect to the projecting plane.
A major advantage of method of the present invention is, can be depended on projector with respect to the corresponding distance on projecting plane and/or angle is mated and be optimized to different parameters thus by the image projected data.Said coupling at first is meant change (modification) or optimizes the information content and/or the legibility of each pictorial element want image projected under the application's meaning, but especially also refers to this method of optimization or projector aspect energy consumption.At this moment, under the application's meaning, pictorial element both can have been represented an independent picture point, also can represent by the information content that can demarcate of on a plurality of picture point, extending of image projected.
The definite of relative orientation between the measurement of distance or projector and the projecting plane can or only carry out once before the beginning projection or during projection, carry out repeatedly or also can carry out continuously with certain interval.Thus, even the distance between projector during the projection and projecting plane changes or direction changes the coupling that also can carry out requirement to pictorial element.
Method is by means of independently range sensor and/or angular transducer are confirmed distance and/or relative orientation between projector and the projecting plane in known manner.But it is favourable utilizing existing sensing system to carry out these measurements, and for example this sensing system is mounted for automatic focusing or is used for Flame Image Process to revise distortion in many projector.The measured value that exists only need carry out corresponding further analyzing and processing through simple algorithm then in the control of optical projection system and/or regulon.Control and/or regulon also advantageously are disposed in the projector, all are present in the projector thereby implement the needed device of said method.But, by means of the external system of this projector of control, the view data that project on the projecting plane is complementary with the distance that is determined or with relative orientation, equally also be possible.
In addition also can with range information be stored in the storer and when the projecting image data projection centre axis through reading distance and/or projector between at least one point that this information confirms projector and projecting plane from storer with respect to the position on projecting plane.This information for example can just be stored in the storer during a calibration process.Under the projection arrangement situation of activity, also can the positional information of projector with respect to the projecting plane be provided to the place of projector.Work on such place if found out projector, from a chart, projector is distributed to this place with respect to one of the projecting plane corresponding distance or positional information so.If there be corresponding range information or the positional information of projector, through utilizing confirming of carrying out under the memory cell situation, just can save a measuring process that is used to measure distance so with respect to the projecting plane.Also can prevent thus during measuring, possibly cause the measurement result distortion owing to the object in the light path.Especially having with respect to the projecting plane under at least one projector situation that roughly keeps constant position or distance, can simplify projecting method of the present invention thus.
In addition, the projection centre axis that will be referred to distance and/or projector between at least one point on projector and projecting plane through interface is given projector with respect to the information conveyance of the position on projecting plane, also is favourable.Need only projector to the projecting plane of range information or positional information there has been to(for) certain projected position, just can import this information and save one-shot measurement thus to projector through interface.This interface for example can be designed to wave point, and it gives projector with corresponding radio signal transmission.But possible in addition is, under the form of passive interface, the bar code of reading of RFID rfid uint or stationkeeping setting for example offers this information a suitable receiving element of projector.
Therefore in a word, a kind of method of easy enforcement is provided by this way, this method has realized images displayed information is filtered targetedly and guaranteed better clearness and improved identifiability or legibility.Cause whole optical projection system to have better navigability thus and obviously improve the ease for use of optical projection system thus on the whole according to method of the present invention.
Some the favourable expansion scheme and the improvement of method of the present invention have been provided in the dependent claims.
For example particularly advantageously be; By means of about the positional information between projector and the projecting plane and/or about projector with respect to the directed information on projecting plane confirm by the display size of image projected data with make at least one pictorial element, preferred a plurality of pictorial elements and this display size are complementary.The decision standard of this coupling is the display size of view data on the projecting plane in the case.This display size depends on the optical characteristics and its distance to the projecting plane of projector.In the optical characteristics of projector, it is especially important reflection angle at this, it confirms the size of institute's images displayed data with the distance between projector and projecting plane.If the cicada display size that can calculate by means of simple algorithm can make so and want the image projected data correspondingly to be matched with by the size of image projected thus.Like this, can make view data and be associated by the display size that supplies use generally of projects images and can optimize picture material especially simply thus.
Particularly advantageous in addition is to make the picture point number of the view data of projector projects be complementary and/or be complementary with the display size that is determined with the information about distance and/or position that is determined.Particularly when display text on the projecting plane, structure or control element, advantageously, can for example change the picture point number, to reach optimum matching ground display image data according to display size.In order to change the picture point number or by the image projected pixel, view data is preferably throwed by means of laser-projector.Conventional projector throws identical picture point number all the time, and no matter on the projecting plane, can show by image projected muchly.On the contrary; Recently laser-projector can change its picture point number that can throw; Thereby using under the laser-projector situation, also can make the picture point number of wanting image projected and the distance between projector and projecting plane is complementary and/or mate with respect to the oriented phase on projecting plane with projector and/or be complementary with display size.Distance between projector and projecting plane is corresponding hour, then for example can reduce the picture point number of wanting image projected and reduce the energy consumption of projector thus, and the while is not reduced the legibility of image information.
This moment is particularly advantageous to be to make at least one pictorial element, and the picture point number of preferred a plurality of pictorial elements and projector is complementary.After the picture point number is changed, can in image, the quantity of images displayed information also change.If increase the picture point number, then can correspondingly show more images information, if reduce the picture point number, then correspondingly show less image information.Therefore, employing can make according to method of the present invention and want image projected data and the picture point number that is throwed to mate best.
According to special preferred embodiment regulation of the present invention, make said at least one pictorial element want to be complementary on the information content of image projected data at them being complementary by image projected data inside and/or making on its size and/or on the layout at it.Can arrive better clearness and legibility to wanting the image projected data and filtering targetedly and therefore make according to the applicable cases of needs thus by image projected.If the projecting plane for example is a kind of interactively projection display; So for this projection display has better operability, each pictorial element or be included in them the information content also can be changed on their size and area ratio in a hope of whole images displayed under throw.
Also the layout of wanting the image projected data can be changed, thereby their position can be selected best corresponding to the information content of display size and/or view data.
Also can advantageously on their information content, change image information.In the case, make especially in this wise and want the image projected Data Matching, promptly their information content is coordinated with the picture size that supplies to use best mutually.Therefore, corresponding to the information content of the picture display size filtering image data of supply using.Though for example can under little display size situation, leave out want in the image projected be hope be not necessarily the information content that needs.Thisly can additionally be used for showing better the main information content in the space of wanting the inner extra acquisition of image projected.
Particularly advantageously in addition be; For at least one wants the images displayed element; Be preferably a plurality of pictorial elements and in a storage arrangement, store at least two; Preferred a plurality of different display formats each other wherein depend on the information about the information of the distance between projector and projecting plane and/or relative position that is determined and are said at least one pictorial element and select a display format respectively and throw.
According to another preferred implementing form, display size that foundation is determined and/or distance or relative position mate by the brightness of image projected and/or contrast.For example, automatically use the brightness and/or the contrast adjustment that are set for certain distance and/or angular orientation between projector and projecting plane.This for example can be implemented in and reduces brightness under the corresponding little display size and also reduce energy consumption thus.
According to another preferred implementing form, the distance of at least two points on projector to projecting plane is confirmed in suggestion, preferably at least three of the projecting plane point-blank the distances of point not.Can additionally also automatic image correction be integrated into the support parameter that is used as Flame Image Process in the projector and with range observation thus.
If the projection centre axis of projector and projecting plane are not mutual perpendicular positionings, so always hope to carry out automatic image correction.According to the method for three distances of measurement of suggestion,, also can revise this moment reliably with respect to the beholder occurred by the distortion of projects images by means of proofreading and correct automatically even projecting plane itself is not a vertical orientation.This can not realize for traditional Keystone correction method of adopting the obliquity sensor on the projector.
Also can confirm the position of the projection centre axis of projector thus with respect to the projecting plane.If measured the distance on two points, the projection centre axis that so just can judge projector is with respect to the degree of tilt of projecting plane around an axis, is not positioned on this axis or is positioned on the straight line with this parallel axes as long as this two points are not the boths.If to three not point-blank the distance of point be known, can determine the orientation of projecting plane so basically with respect to the projection centre axis of projector.Additional measurement point of every increase just can be confirmed the shape on projecting plane more accurately and therefore improve correction result.
Can certainly not carry out range observation and implement according to method of the present invention, can swing or the oscillating motion or the rotational motion of the projector of rotating support if for example determine by means of angular transducer with the projection centre axis of confirming projector orientation with respect to the projecting plane.The angle position that therefore, can depend on projector changes or optimizes by the image projected data.The mensuration of this angular orientation to projector can certainly combine with the Determination of distance to projector to projecting plane.
In another form of implementation, can also pass through initial position sensor, for example be used for gps system, confirm the location of projector with respect to the projecting plane, the position of this projector must be known.Thisly confirm and can or implement, perhaps also can implement that this device that adds is transferred to projector with respect to the corresponding information of the position on projecting plane through interface with projector then through additional device through the device of projector itself.This information can advantageously be stored in the storer of projector then.In other form of implementation; As long as projector has been equipped with the corresponding readout device that is used for passive information carrier, also can on a projection place, give projector with corresponding mode with information transmission like for example RFID chip or bar code or out of Memory carrier near the projector through passive information carrying means.If projector is arranged to one with respect on the fixing precalculated position, projecting plane; For example be placed in a support or be arranged on the fixed mount, then can will be transferred to projector about the corresponding information of the position on projector to projecting plane through passive massaging device.If projector moves with respect to the projecting plane, so also can to the projection circuit with the projecting plane with respect to the corresponding location storage of projector in projector or be transferred to projector through appropriate interface.Possible in addition is; Have the corresponding information of projector at projector with respect to the position on projecting plane; But only transmit projector through interface and on a highway section, just in time be in which locational information, this moment, projector was directed to the projecting plane along this highway section.By the highway section indication of this transmission, projector can be confirmed position or the distance that projector is just in time had with respect to the projecting plane through calling storer.
In addition, in another embodiment, except considering distance, still can consider the quality on projecting plane.If have only one can supply to try out to the not really suitable projecting plane of projection; The surface of big roughness for example; The wall that did not for example clean is even have the enough interference that also can receive the roughness on projecting plane apart from situation hypograph impression that are fit to the projection bulk information so.It is favourable that the information content of images displayed data is wanted in same in this case minimizing, so that guarantee that the user can easily read.In one first form of implementation, the user for example preestablishes the projecting plane through suitable operating unit, for example screen, robust fibre wall cloth or coarse wall.Then; Depend on this preestablishing; Can under the situation of considering distance, select the correct demonstration of picture material and especially select suitable image information content by the control module of projecting cell; But wherein guaranteed to have guaranteed the information content as much as possible on the other hand by readability on the one hand.In another form of implementation, also can observe by image projected and will compare with the contrast of under the best image situation, expecting through camera head by the contrast of projecting plane decision.Can discern thus interference that the roughness by the projecting plane causes and in case of necessity through reduce details that image shows and complicacy make image show with the projecting plane on interference structure be complementary and especially be complementary with the excessive roughness on projecting plane.Except mating under the projection situation on the fixing wall, also can be on the face of activity mate during projection, as for example on the water surface or on fogbank.When mating, except making the information content and projecting plane coupling, the parameter that also can mate other in case of necessity simultaneously is like the brightness of for example projection light source.Also can consider the distance of beholder in the case, make the beholder dazzling so that for example avoid apart from the projecting plane.
Theme of the present invention is a kind of being used for view data to be projected to the device on the projecting plane in addition, and this device especially is applicable to the method for implementing aforementioned type.This device comprises projector; Be used to measure the distance between at least one point on projector and projecting plane and/or be used to measure the mechanism of the projection centre axis of projector with respect to the orientation on projecting plane; And control and/or regulon, wherein can make the view data that will project on the projecting plane on one or more pictorial elements and the distance between projector and projecting plane and/or be complementary with the projection centre axis of projector position with respect to the projecting plane by means of this control and/or regulon.
Especially can be of portable form this moment according to projector of the present invention, for example be implemented as the Beamer projector, perhaps also can advantageously be implemented as the indicating device in the adjustable head-up display scope in automobile.
Particularly advantageous be this moment; Be used to measure the distance between at least one point on projector and projecting plane and/or be used to measure the mechanism of the projection centre axis of projector, and preferably also have control and/or regulon all to be integrated in the projector with respect to the position on projecting plane.
According to a preferred especially form of implementation of the present invention, the regulation projector is a laser-projector.A scanister that has the reflective mirror of one or more activities can constructed and comprise for this reason to laser projection system especially on the basis of scanner.At this known particularly twin shaft micromechanics formula sweep test, can be through them with laser beam at two axis upper deflectings, so that on the projecting plane, produce the display image of hoping.The repetition rate (refresh rate) of the image that produces so for example can be 60Hz.The laser beam that so is deflected is mapped on the projecting plane and is scattered there perhaps with clearly defined objectively to be expanded along the direction in space that limits, thereby on the projecting plane, forms real image.Preferred laser cell this moment can be arranged on the same side on projecting plane with the beholder and with this or these laser beam at least basically from beholder's direction of visual lines guiding projecting plane.Alternatively, under so-called rear-projection projection situation, it is partially transparent that the projecting plane also may be embodied to, and wherein from the beholder, laser cell is arranged on the back on projecting plane and the back side that laser beam is directed to the projecting plane.Especially in the display application field, the projecting plane for example also can use the micro lens grating that is configured to plastic components as the projecting plane.
The accompanying drawing summary
Some embodiments of the present invention shown in the drawings, these embodiment will describe in detail in following explanation.Shown in the accompanying drawing:
Fig. 1: at synoptic diagram according to the light path of the projector in the device of the present invention;
Fig. 2 a: embodiment who is projected to the view data on the projecting plane; With
Fig. 3: a projecting plane littler than Fig. 2, it has the view data of corresponding coupling.
Form of implementation of the present invention
Fig. 1 illustrates the laser-projector 1 with lens 2.Through the lens 2 of laser-projector 1, image 4 is projected on the projecting plane 5 with projection centre axis 3 vertical orientations along projection centre axis 3.Laser-projector 1 is arranged on and projecting plane 5 distance 6 parts of being separated by.Projector 1 is the reflection angle alpha of benchmark and the display size 7 that distance 6 has confirmed to be projected the image 4 on the projecting plane 5 together with projection centre axis 3.Obviously, under the reflection angle alpha situation of constant projector 1, along with the change of distance 6, the display size 7 of image 4 is changed on length and width pro rata.
The view data 8a that is projected the image 4a on the projecting plane by laser-projector has been shown among Fig. 2.Image 4a contains the common information data of weather station herein.The information content of image 4a is optimised on the display size of view data 8a.In order to make image information more very clear, image 4a is divided into three subregion O, the structure of M and U for this reason.
In the O of the subregion on top, throwed the date pictorial element 9 and temporal image element 10a arranged up and down, wherein time read 10a is outstanding by obviously.In the M of the subregion of centre, show the pictorial element 11 of relevant internal temperature data, about the pictorial element 13 of the pictorial element 12a of external temperature and the relevant alerting signal that is associated with these temperature datas and with the pictorial element 14a shown in the corresponding symbol with written form.Subregion M is divided into two parts at this moment again.In the part at an upper portion thereof, with the mode of form character " interior " and " outward " and affiliated with it temperature data are set with pictorial element 11 and 12a, wherein the character of pictorial element 12a " outward " quilt is given prominence to overstriking a little.The bottom of subregion M, in the much the same big part, the alerting signal that joins with temperature correlation is significantly given prominence on the size of letter and thickness as pictorial element 13.The image section U of bottom has shown the weather forecast that has literal and symbolic component as pictorial element 15.
The view data 8a that is projected the image 4a on the projecting plane is thus by structuring well, makes the information content read easily and a glance just can understand and master thus.The information content of particular importance is significantly outstanding for the beholder has done.
Fig. 3 show Fig. 2 by a kind of variation of image projected 4a.Because the distance between laser-projector and the projecting plane is less, image 4b shown in Figure 3 projected one than the image 4a among Fig. 2 little on the image surface of Duoing.For clearness and the legibility of optimizing image information, the information content that will throw of image 4b will be coordinated with the display area or the display size that supply to use mutually.For this reason, each pictorial element of image projected data 8b on its size, its layout and its information content, to be adjusted by coupling.
Wanting the information content of image projected 4b to be adjusted to little a lot of display size is complementary.The information of related date 9, internal temperature 11 and the weather forecast 15 that also shows among the image 4a in Fig. 2 or pictorial element are not projected on the projecting plane in Fig. 3 now again.In addition, in image 4b, cancelled the pictorial element 13 of the textual alerting signal that in the image 4a of Fig. 2, shows and only show herein than the textual alerting signal little the pictorial element of the bell character 14b of Duoing.Therefore the view data 8b of image 4b only comprises information or pictorial element and the bell character 14b about time 10b, external temperature 12b.
In order to help discerning bell character 14b better, also changed the pictorial element 10b of view data 8b, the layout of 12b and 14b.External temperature indication 12b directly is arranged in below the time read 10b.Indicate the dangerous bell character 14b of ice sheet and in image 4b, illustrate with the left border limit that external temperature indication 12b is displaced to image with respect to time read 10b, this bell character indicates 12b more obvious than time read 10b and external temperature thus, sees easily.
The font size that relates to pictorial element 10b and the 12b of the indication of time read and external temperature also is exaggerated in image 4b and with the font type of change it is matched each other on form and size; Thereby being compared with 12a (Fig. 2) with image information 10a in image 4a in image 4b by image projected information 10b and 12b (Fig. 3); Although the display size on the whole of image 4b is dwindled, but illustrated obviously biglyyer.Therefore, although display size is less, the information content of image 4b has comprised all important information contents of image 4a.
