Abstract
The invention provides a multipoint analyzing method in an interactive system, comprising the steps as follows: 1) defining an area for collecting the movement and a position signal of an object; 2) outputting emitted light to the defined area so as to illuminate the object; 3) collecting the reflection of the emitted light, and obtaining the continuous movement or position images of the object in the defined area; 4) analyzing two continuous frames of the continuous images to obtain an overall difference, and obtaining a two-dimensional data coordinate of the object outline; 5) analyzing the two-dimensional data coordinate to obtain a two-dimensional data vertex coordinate; 6) taking the vertex coordinate as the object local interactive area. The multipoint analyzing method has the beneficial effect that interaction is carried out through the object movement or position without any external auxiliary locating equipment.
Description
Technical field
The invention belongs to art of image analysis in the interactive system, especially relate to multiple spot analytical approach in the interactive system.
Background technology
Usually exchange method all is by means of handheld device or specifies medium to carry out reciprocal process in existing technology; This analysis method shows whole profile through the two-dimensional array coordinate through the profile that picture catching and analysis obtain the person again; Interactive device in the past all is by means of handheld device or specifies medium to carry out reciprocal process that receiving the device-restrictive user can only wear or carry equipment could be mutual with equipment.In the middle of large-scale place, use very inconvenience, and have complex structure, the part processing difficulty, adjustment is wasted time and energy, and inefficiency uses technical matterss such as inconvenience.
Summary of the invention
The purpose of this invention is to provide and a kind ofly carry out alternately through object activity or position, need not be by multiple spot analytical approach in the interactive system of any external auxiliary positioning equipment.
Technical scheme of the present invention is: multiple spot analytical approach in the interactive system, be used for carrying out alternately through the activity and the position of analytic target, and this method may further comprise the steps:
1) defines the zone of the movable and position signalling of acquisition target;
2) irradiate a plurality of objects in the present delimited area to institute's delimited area output emission light;
3) collection emitting reflection of light, and obtain a plurality of objects moving or the position consecutive image in institute's delimited area respectively;
4) through two frame analyses before and after the consecutive image of each object are obtained global disparity, obtain the 2-D data coordinate of each object outline;
5) through the 2-D data coordinate analysis, obtain the 2-D data apex coordinate, obtain a plurality of contours of objects and movable and position mobile status.
Further, a plurality of objects are meant two or more objects.
Further, said emission light is invisible light.
Further, said emission light is infrared light.
Advantage and good effect that the present invention has are:
Owing to adopt technique scheme; With the process of computer interactive in abandoned traditional input equipment; Overcome just do not carry can with the inconvenience of computer interactive; And reduced the use cost of equipment, simplified the structure, be easy to make, failure rate is low, safe and reliable, energy-conserving and environment-protective, be convenient to operation or the like, especially the performance of this exchange method is excellent aspect the loss of equipment.
Description of drawings
Fig. 1 is the object's position synoptic diagram in the delimited area of the present invention.
Embodiment
As shown in Figure 1, the multiple spot analytical approach of interactive system has the following steps:
1) defines the zone 1 of the movable and position signalling of an acquisition target 3;
2) irradiate a plurality of objects 3 in the present delimited area 1 to institute's delimited area 1 output emission light 2;
3) reflection of collection emitting light 2, and obtain a plurality of objects 3 moving or the position consecutive image in institute's delimited area 1 respectively;
4) through two frame analyses before and after the consecutive image of each object 3 are obtained global disparity, obtain the 2-D data coordinate of each object 3 profile 4;
5) through the 2-D data coordinate analysis, obtain the 2-D data apex coordinate, obtain profile 4 and movable and the position mobile status of a plurality of objects 3.
Because in the interactive system, the next door that the zone of defining 1 can be positioned at the interactive image of wanting also can coincide with the mutual image of want, said here interactive image is the image of showing to user or spectators; Projector projects can be passed through, also video screen can be used, and the work of and position signal acquisition movable for object 3; Adopt video camera to accomplish, video camera can capture the dependent picture of interactive image like this, for fear of the influence of interactive image to signals collecting work; For these two work of reflection of output emission light 2 and collection emitting light 2, take with infrared ray with video camera, eliminate the interference of interactive image; When taking, can convert the incoming frame of video camera to gray level simultaneously; To reduce data volume and to simplify the acquisition process process, can also make incoming frame fuzzy to reduce noise, at this time just can two frame analyses before and after the consecutive image of each object 3 be obtained global disparity; Obtain the 2-D data coordinate of each object 3 profile 4; Through the 2-D data coordinate analysis, obtain the 2-D data apex coordinate, obtain profile 4 and movable and the position mobile status of a plurality of objects 3; Then according to the different mobile statuss of a plurality of objects 3, around each object 3, make different mutual.
More than one embodiment of the present of invention are described in detail, used specific case herein principle of the present invention and embodiment set forth, the explanation of above embodiment just is used for help understanding method of the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
Claims (4)
