Description
Technical Field
The present invention relates to a projector recommending method and a projector recommending system, and more particularly, to a projector recommending method and a projector recommending system capable of automatically recommending a projector according to a projection requirement.
Background
Recently, the application of projectors is becoming more and more widespread. Besides being used for meeting reports in general offices, projectors are often used in various special discussions or academic courses because of their audio-visual playing functions. When a user wants to install a projector on a site, the user often only provides information such as the size of the site, the size of the projection plane, the expected installation location of the projector, etc. to the system provider. Because of the wide variety of projectors on the market, it is difficult for the system provider to recommend a proper projector to the user according to the information provided by the user.
Disclosure of Invention
The invention aims to provide a projector recommending method and a projector recommending system which can automatically recommend a projector according to projection requirements, so as to solve the problems.
According to one embodiment, the projector recommendation method of the present invention comprises the steps of: providing a comparison table, wherein the comparison table records a plurality of projectors and a plurality of projection parameters corresponding to each projector; inputting the size of a projection plane, a projection distance and ambient brightness; calculating projection length according to the projection plane size, a target image ratio and a splicing mode, calculating a target projection ratio according to the projection distance and the projection length, and calculating target minimum projection brightness according to the environment brightness, a preset brightness quasi-position and a projection area; and generating a projector recommendation result according to the target minimum projection brightness, the target projection ratio, the target resolution corresponding to the target picture ratio and the plurality of projection parameters.
According to another embodiment, the projector recommendation system of the present invention comprises a database, an input interface, a processing unit and a display unit. The database stores a comparison table, wherein the comparison table records a plurality of projectors and a plurality of projection parameters corresponding to each projector. The input interface is used for inputting the projection plane size, the projection distance and the ambient brightness. The processing unit calculates the projection length according to the projection plane size, the target image ratio and the splicing mode, calculates the target projection ratio according to the projection distance and the projection length, and calculates the target minimum projection brightness according to the environment brightness, the preset brightness level and the projection area. The processing unit generates a projector recommendation result according to the target minimum projection brightness, the target projection ratio, the target resolution corresponding to the target picture ratio and the plurality of projection parameters. The display unit is used for displaying the recommendation result of the projector.
Compared with the prior art, when a user wants to erect the projector at a place, the user only needs to input the projection plane size, the projection distance and the ambient brightness on the input interface, and the corresponding projector recommendation result can be automatically generated. When the projector in the database meets the projection requirement, the invention can generate a projector recommendation list comprising at least one candidate projector for the user to refer to. Thus, the user can quickly find the projector meeting the projection requirement through the recommendation list of the projector. Otherwise, when no projector in the database meets the projection requirement, the invention can generate a notification message to notify the user that there is no projector meeting the projection requirement. At this time, the user can adjust the projection requirement according to the notification message or the system manager can add other projectors into the database, so that the projector recommending system recommends the appropriate projector again. Therefore, the present invention can make the installation of the projector more efficient and convenient.
The advantages and spirit of the present invention can be further understood by the following detailed description of the invention and the accompanying drawings.

As shown in fig. 1, the projector recommendation system 1 includes a database 10, an input interface 12, a processing unit 14 and a display unit 16. In practical applications, the database 10 and the processing unit 14 may be provided by a server, and the display unit 16 may be provided by a user device (e.g., a computer), wherein the server and the user device may be in communication in a wired or wireless manner.

TABLE 1
When a user wants to use the projector recommendation system 1 to recommend a projector suitable for being installed in a field, the user first operates the user device to display the input interface 12 on the display unit 16. As shown in fig. 3, the input interface 12 is used for the user to input the projection plane size, the projection distance and the ambient brightness of the venue (step S12 in fig. 2). The projection plane dimensions may include a projection plane width and a projection plane height. In this embodiment, the ambient brightness can be set by the user. In addition to user settings, the input interface 12 may provide a plurality of preset ambient intensities for the user to select. As shown in fig. 3, input interface 12 may provide, but is not limited to, low ambient brightness (e.g., museum), medium ambient brightness (e.g., classroom), and high ambient brightness (e.g., mall). For example, the low ambient brightness may be preset to about 150lux, the medium ambient brightness may be preset to about 250lux, and the high ambient brightness may be preset to about 350 lux.
In this embodiment, it is assumed that the projection plane width is 6.4m, the projection plane height is 2m, the projection distance is 3m, and the ambient brightness is 300 lux. After inputting the projection plane size, the projection distance, and the ambient brightness, the processing unit 14 calculates the projection length according to the projection plane size, the target frame ratio, and the splicing method, calculates the target projection ratio according to the projection distance and the projection length, and calculates the target minimum projection brightness according to the ambient brightness, the preset brightness level, and the projection area (step S14 in fig. 2). In addition, the processing unit 14 can calculate the number of projectors corresponding to the target resolution according to the projection plane size, the target frame ratio, the stitching method and at least one minimum overlap level.
In this embodiment, the splicing manner may be at least one layer of horizontal projection (landscaping projection) side-by-side splicing or at least one layer of vertical projection (raster projection) side-by-side splicing. As shown in fig. 4, four stitching methods can be preset in the present invention, wherein the oblique line portion is the overlapping area of two adjacent projected images. It should be noted that the splicing manner can be determined according to practical applications, and is not limited to the embodiment shown in the drawings. How step S14 in fig. 2 is performed is illustrated below by "single-layer transverse projection side-by-side stitching" and "double-layer longitudinal projection side-by-side stitching", respectively. It should be noted that the following numerical values are all expressed by rounding off the actual numerical values. Therefore, if the correlation operation is directly performed by the following numerical values, there will be a slight difference.
And (3) splicing the single-layer transverse projections side by side:
the following description is directed to a projector with a target resolution of XGA (i.e., target resolution of 1024 × 768 and target frame ratio of 4: 3). First, the processing unit 14 makes the height of the projection screen of a single projector match the height of the projection plane by 2m, and then splices a plurality of projectors according to the width of the projection plane by 6.4 m. In this embodiment, the minimum overlapping level of two adjacent projected images in the horizontal direction is preset to be 10%. In other words, the overlapping rate of two adjacent projected images in the horizontal direction cannot be less than the minimum overlapping level by 10%. It should be noted that the minimum overlap level in the horizontal direction can be preset by the system or set by the user, depending on the actual application. Therefore, when the height of the projection plane is 2m and the target frame ratio is 4:3, the width of the projection frame of a single projector is 2.67m, wherein the width of the projection frame of the single projector is the projection length. When the width of the projection plane is 6.4m, the number of the projectors required by single-layer transverse projection side-by-side splicing is 3. At this time, the overlapping rate of the two adjacent projection images in the horizontal direction is 30% (i.e., 3 × 2.67m-2.67m × 30% × 2 ═ 6.4 m). In addition, the target projection ratio is a ratio of the projection distance 3m to the width 2.67m of the projection screen of the single projector (i.e., the projection length described above). Therefore, the target throw ratio is 1.13. In this embodiment, the predetermined brightness level may be 3 times of the ambient brightness. It should be noted that the preset brightness level can be preset by the system or set by the user, depending on the actual application. Therefore, the target minimum projection brightness may be 3 times the ambient brightness (i.e., 300lux 3) and the projection area of a single projector (i.e., 2m 2.67m 5.333 m)2) The target minimum projection brightness is 4800lumen (i.e., 900lux 5.333 m)2＝4800lumen)。
When the target resolution is WUXGA (i.e., the target resolution is 1920 × 1200 and the target frame ratio is 16:10), WXGA (i.e., the target resolution is 1280 × 800 and the target frame ratio is 16:10), 4K (i.e., the target resolution is 3840 × 2160 and the target frame ratio is 16:9) or 1080p (i.e., the target resolution is 1920 × 1080 and the target frame ratio is 16:9), the processing unit 14 may also calculate the width of the projection frame of the corresponding single projector, the number of projectors, the overlapping ratio of the two adjacent projection images in the horizontal direction, the target projection ratio, and the target minimum projection brightness according to the above-described method. As shown in table 2 below, table 2 records the calculation results corresponding to different target resolutions.
TABLE 2
Splicing the double-layer longitudinal projection side by side:
the following description is directed to a projector with a target resolution of XGA (i.e., target resolution of 1024 × 768 and target frame ratio of 4: 3). First, the processing unit 14 will make the height of the projected image of two projectors in the vertical direction match the height of the projection plane 2m, and then the projectors will be spliced according to the width of the projection plane 6.4 m. In this embodiment, the minimum overlap level of the two adjacent projected images in the horizontal direction is preset to be 10%, and the minimum overlap level of the two adjacent projected images in the vertical direction is preset to be fixed to be 20%. In other words, the overlapping rate of the two adjacent projected images in the horizontal direction is not less than 10% of the minimum overlapping level, and the overlapping rate of the two adjacent projected images in the vertical direction is equal to 20%. It should be noted that the minimum overlap level in the horizontal direction and the vertical direction can be preset by the system or set by the user, depending on the application. Therefore, when the height of the projection plane is 2m and the minimum overlapping level of two adjacent projection images in the vertical direction is fixed at 20%, the height of the projection screen of a single projector is 1.11m, wherein the height of the projection screen of a single projector is the above projection length. In addition, since the target frame ratio is 4:3, the width of the projection frame of a single projector is 0.83m, is added. When the width of the projection plane is 6.4m, the number of projectors required for the double-layer longitudinal projection side-by-side splicing is 9 × 2. At this time, the overlapping ratio of the two adjacent projection images in the horizontal direction is 16.5% (i.e., 9 × 0.83 m-0.83 m × 16.5% × 8 ═ 6.4 m). In addition, the target projection ratio is a ratio of the projection distance 3m to the height 1.11m of the projection screen of the single projector (i.e., the above projection length). Therefore, the target throw ratio is 2.7. In this embodiment, the predetermined brightness level may be 3 times of the ambient brightness. It should be noted that the preset brightness level can be preset by the system or set by the user, depending on the actual application. Therefore, the target minimum projection brightness may be 3 times the ambient brightness (i.e., 300lux 3) and the projection area of a single projector (i.e., 1.1111m 0.8333m 0.925 m)2) The target minimum projection brightness is 833lumen (i.e., 900lux 0.925 m)2＝833lumen)。
When the target resolution is WUXGA, WXGA, 4K or 1080p, the processing unit 14 may also calculate the height and width of the projection screen of the corresponding single projector, the number of projectors, the overlapping ratio of two adjacent projection images in the horizontal direction, the target projection ratio and the target minimum projection brightness according to the above-mentioned manner. As shown in table 3 below, table 3 records the calculation results corresponding to different target resolutions.
TABLE 3
It should be noted that the calculation principle of the "single-layer longitudinal projection side-by-side splicing" and the "double-layer transverse projection side-by-side splicing" is substantially the same as the calculation principle of the "single-layer transverse projection side-by-side splicing" and the "double-layer longitudinal projection side-by-side splicing", and is not described herein again.
Next, the processing unit 14 generates a projector recommendation result according to the target minimum projection brightness, the target projection ratio, the target resolution corresponding to the target screen ratio, and the plurality of projection parameters of each projector (step S16 in fig. 2). The display unit 16 is used to display the recommended result of the projector.
In this embodiment, the processing unit 14 can first determine whether the plurality of projection parameters of each projector meet the target minimum projection brightness, the target projection ratio and the target resolution. When the plurality of projection parameters of at least one candidate projector of the plurality of projectors meet the target minimum projection brightness, the target projection ratio, and the target resolution, the processing unit 14 may generate a projector recommendation list as a projector recommendation result, wherein the projector recommendation list lists the at least one candidate projector. In this embodiment, the resolution of the candidate projector needs to be the same as the target resolution, the minimum projection brightness of the candidate projector needs to be greater than or equal to the target minimum projection brightness, and the throw ratio of the candidate projector needs to cover the target throw ratio. In this embodiment, when the candidate projector includes a plurality of shots, the processing unit 14 may further select at least one candidate shot from the plurality of shots of the candidate projector according to the target throw ratio, and the projector recommendation list may list at least one candidate shot together.
As shown in tables 1 and 2, projector P4 meets the projection requirements described above for single-layer lateral projection side-by-side tiling. Thus, projector P4 is a candidate for single-layer lateral projection side-by-side stitching. As shown in tables 1 and 3, the lens L1 of the projector P6 meets the above projection requirements for the side-by-side splicing of the two-layer longitudinal projection. Therefore, the projector P6 is a candidate projector for double-layer longitudinal projection and side-by-side splicing, and the lens L1 is a candidate lens. Therefore, as shown in FIG. 5, the projector recommendation list includes projector P4, projector P6 and lens L1 for the user to refer to. In addition, the projector recommendation list may further list the number of required projectors P4, P6 for the user to refer to.
On the other hand, when none of the projection parameters of the projectors meets the target minimum projection brightness, the target projection ratio and the target resolution, the processing unit 14 may generate a notification message as the projector recommendation result. For example, the notification message may indicate that there is no projector or other similar message meeting the projection requirements. At this time, the user can adjust the projection requirement according to the notification message or the system manager can add other projectors into the database, so that the projector recommending system 1 recommends the appropriate projector again.
To sum up, when a user wants to set up a projector in a field, the user only needs to input the projection plane size, the projection distance and the ambient brightness on the input interface, and the invention can automatically generate the corresponding projector recommendation result. When the projector in the database meets the projection requirement, the invention can generate a projector recommendation list comprising at least one candidate projector for the user to refer to. Therefore, the user can quickly find the projector meeting the projection requirement through the projector recommendation list. Otherwise, when no projector in the database meets the projection requirement, the invention can generate a notification message to notify the user that there is no projector meeting the projection requirement. At this time, the user can adjust the projection requirement according to the notification message or the system manager can add other projectors into the database, so that the projector recommending system recommends the appropriate projector again. Therefore, the present invention can make the installation of the projector more efficient and convenient.
The present invention has been described in relation to the above embodiments, which are only exemplary of the implementation of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the invention. Rather, it is intended that all such modifications and variations be included within the spirit and scope of this invention.
