Abstract
The invention discloses a three-dimensional surface projection presentation system. The three-dimensional surface projection presentation system is characterized by comprising photosensitive sensors, an optical signal detection board and a computer end control program. According to the three-dimensional surface projection presentation system, three-dimensional surface projection can be rapidly calibrated, only a plurality of seconds are spent in the whole process, and the attachment degree of a three-dimensional projection face is very high.
Description
Technical field
Invention relates to controlling projection regulation technology field, specifically belongs to a kind of three-dimensional surface projection and presents system.
Background technology
When projection target thing is on-plane surface, need to consider the surperficial rectification of projected picture and the 3D solid of plane.For example, when needs are on cubical three faces during projection, traditional scheme is to utilize three projecting apparatus respectively toward projection on a face, in traditional three-dimensional surface projection, core concept is to set up an accurate 3 d surface model, then this model is being put into the coordinate zero point of 3D engine, and the virtual camera position in engine is being set to solid projection instrument with respect to the three dimensional space coordinate of entity three-dimensional surface.But this process is very difficult, need constantly to attempt position and the angle of adjustment projecting apparatus, to reach satisfied effect.Particularly, after projecting apparatus rocks, again adjust and waste time and energy.
Summary of the invention
The object of invention has been to provide a kind of three-dimensional surface projection and has presented system, can calibrate rapidly three-dimensional surface projection, and whole process is consuming time needs only several seconds, and three-dimensional projection plane's laminating degree is fine.
The technical scheme that invention adopts is as follows:
A kind of three-dimensional surface projection presents system, comprise light sensor, optical signal detecting plate and computer end control program, light sensor is arranged at needs the three-dimensional surface of projection to imbed, described light sensor be 4 not coplanar, 4 light sensors are connected to Yi Ge tetra-tunnel optical signal detecting plates, check-out console is by serial ports and the communication of computer end control program, computer end control program controlling projection picture shows specific rectification picture successively, detect for corresponding 4 states of coplanar light sensor not of every width picture simultaneously, computer control end program can draw and imbed the light sensor of three-dimensional projection plane with respect to the two-dimensional coordinate of projected picture these data analysis, space coordinates in conjunction with light sensor in entity three-dimensional projection plane, by POSIT algorithm, we can obtain projecting apparatus with respect to locus coordinate and the spin matrix of three-dimensional projection plane, by the location parameter obtaining and spin matrix, give the virtual video camera in 3D engine, 3D engine picture is exactly the image through calibration by projector projects to the image in three-dimensional projection plane.
Described optical signal detecting plate, by micro-signal processing, high-precision A/D collection, low-power consumption high speed ARM processing controller the electric circuit constitute, micro-signal treatment circuit changes into voltage signal by photo-signal, high-precision A/D acquisition channel can gather plurality of voltages signal simultaneously, by synchronous decision algorithm, signal is carried out to multicycle collection average treatment, the quick arm processor of low-power consumption carries out fast processing calculating to ADC collection signal, thereby inverting obtains concrete azimuth information, arm processor is formed and communicates by letter with host computer by USB interface, realizes parameter transmission.
Compared with the prior art, the beneficial effect of the invention is as follows:
Invention only utilizes a projecting apparatus just can realize in cubical three face projections, and the effect that the effect presenting is invested respectively a face as three projecting apparatus, can calibrate rapidly three-dimensional surface projection, whole process is consuming time needs only several seconds, and three-dimensional projection plane's laminating degree is fine.
