Abstract
The invention relates to curved surface correction information processing method and device based on a laser locator, wherein the method comprises the following steps: 1) firstly, adjusting projection hardware equipment to locate a projector and projection screen equipment at set positions and directions, and performing step 2); 2) correcting a projection image through a main control machine, adjusting the edge fusion part to enable the image to be tangent to the screen, and performing step 3); 3) locating the specific information of the projection image through the laser locator; 4) judging whether to receive a projection equipment adjusting command through the main control machine, if so, performing step 5); and if not, performing step 7); and 5) adjusting the projection equipment and performing step 6), wherein the device comprises the main control machine, the projector, the laser locator and a projection screen. Compared with the prior art, the method and device disclosed by the invention have the advantages of low cost, convenience in operation and accurate locating data.
Description
Technical field
The present invention relates to a kind of projector equipment bearing calibration and device, especially relate to a kind of curved surface adjustment information processing method and device based on laser locator.
Background technology
To be spliced in the main demonstration and control technology, be used to realize that the seamless spliced technology that the seamless fusion of image shows is one of important technology wherein.Seamless spliced technology be a kind of special, require can to realize the multi-screen image co-registration together, to such an extent as to and will splice the slit and contract to the minimum splicing of coincidence fully than higher projection display applications.In recent years, along with the development of software and hardware technology, seamless spliced technology had been widely used in fields such as display and demonstration, vision amusement, advertisement.
Curved surface adjustment software now; For projector, the position of hardware such as projection screen, angle etc. require very high, in case need adjustment projector or projection screen in the engineering; The adjustment configuration that curved surface adjustment is done then all needs repetitive operation, brings many redundancy of effort burdens to engineering.
Summary of the invention
The object of the invention be exactly provide in order to overcome the defective that above-mentioned prior art exists that a kind of cost is low, operation is convenient, locator data is accurately based on the curved surface adjustment information processing method and the device of laser locator.
The object of the invention can be realized through following technical scheme:
A kind of curved surface adjustment information processing method based on laser locator is characterized in that, comprises following step:
1) earlier the projection hardware device is adjusted, made projector and projection screen equipment be in the position and the direction of setting, execution in step 2 then);
2) main control computer is proofreaied and correct projected image, and the adjustment marginal edge is melted part, and image is suited with screen mutually, and execution in step 3 then);
3) laser locator is gathered the specifying information of projected image;
4) main control computer judges whether to receive projector equipment adjustment instruction, if yes, and execution in step 5); If then execution in step 7 not);
5) projector equipment is adjusted, execution in step 6 then);
6) main control computer obtains the specifying information of historical projected image from laser locator, comes the projection of restored image on projection screen according to the specifying information of this history projected image, and returns step 3);
7) finish.
The specifying information of described projected image comprises position, shape, edge and the curved surface adjustment information of projected image.
A kind of device of the curved surface adjustment information processing method based on laser locator as claimed in claim 1; It is characterized in that; Comprise main control computer, projector, laser locator, projection screen; Described main control computer is connected with projector, laser locator respectively, and described projector, laser locator are aimed at projection screen respectively.
Compared with prior art; The present invention has characteristics such as low cost, locator data be accurate; And relaxed the rectification condition of hardware devices such as projector, projection screen, a lot of facilities can be provided in engineering construction, and saved a lot of times for rectifying and improving part in the engineering accordingly.

Fig. 2 is a workflow diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
As shown in Figure 1; Hardware device of the present invention comprises main control computer 3, projector 2, laser locator 1, projection screen 4; Described main control computer 3 is connected with projector 2, laser locator 1 respectively, and described projector 2, laser locator 1 are aimed at projection screen 4 respectively.
The invention provides the location of projection screen epigraph projection; The user only needs to begin the back in engineering and any time projector is projected on the projection screen; And the image on the projection screen is carried out the position adjust and curved surface adjustment, use the present invention that the image after proofreading and correct is located and record on projection screen then, like this; Even if need adjust equipment such as projector afterwards; According to laser locator institute information recorded image is proofreaied and correct after having adjusted, the workload of image rectification will reduce greatly so again, and project progress is accelerated.
As shown in Figure 2, workflow of the present invention is following:
