Embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment is clearer, below in conjunction with embodiment and accompanying drawing, embodiment is described in further details to the utility model.At this, illustrative examples of the present utility model and explanation thereof are used to explain the utility model, but not as to qualification of the present utility model.
The composition frame chart of a kind of multiple goal treating apparatus that Fig. 1 provides for the utility model embodiment, please refer to Fig. 1, this device comprises: luminophor 11, at least two image acquisition units 12, cluster and filter unit 13, multiple goal separative elements 14, intersect judgement unit 15 and cursor offset control unit 16, wherein:
Luminophor 11 is used to launch light, so that the refractive body on the telepilot can reflect this light, so that the image acquisition units 12 of present embodiment can be obtained with the consecutive image information of the telepilot of thing as a token of of the refractive body on this telepilot.
In the present embodiment, luminophor 11 can be the infraluminescence body, with the emission infrared light; Can be the lasing fluorescence body, with emission laser; Can be visible light emitters also, with visible emitting, present embodiment not with this as restriction.
In the present embodiment, luminophor 11 can be arranged at the reflective position of refractive body that makes things convenient on the telepilot, for example be arranged at around the display screen of terminal of multiple goal treating apparatus of carrying present embodiment, perhaps be arranged at image acquisition units 12 around, present embodiment not with this as restriction.
Each image acquisition units 12 is used to obtain with the refractive body consecutive image information of the telepilot of thing as a token of.
In the present embodiment, this image acquisition units 11 can be a camera, to obtain the image of telepilot by the mode of taking, to obtain its consecutive image information.It can pass through existing any camera chip, and for example Mage-Sensor realizes.
In the present embodiment, telepilot can be one or more.This telepilot is provided with refractive body as moving target, so that camera is known the movement locus of telepilot according to the movement locus of the refractive body that has reflected light, and efficiency confirmed in view of the above target.Wherein, refractive body is made by reflectorized material, need not any power source, and can make different shape as required, satisfies the 3D pattern.
Wherein, consecutive image information is meant the set of diagrams picture that camera photographs in the given time, for example takes 30 two field pictures in 1 second.
In the present embodiment, because a more than camera is set, and each camera all can be gathered the consecutive image information of telepilot, and therefore, corresponding each camera can obtain the consecutive image information of one group of telepilot.
Cluster and filter unit 13 are used for the described consecutive image information that gets access to according to each image acquisition units, confirm the effective target of every two field picture in the described consecutive image that each image acquisition units gets access to, and calculate the center of gravity of each effective target.
In the present embodiment, owing to may have a plurality of targets in the image that camera photographs, for example the target that the light that reflects of the refractive body on telepilot forms, also may have other static or moving targets, the target that forms of the light that sends of sunlight, the light that fixing shot-light sends, the light lamp that rocks or the like light source for example, this cluster and filter unit 13 are used for the consecutive image according to each camera shooting, judge the existence of each effective target.
In the present embodiment, the consecutive image information that corresponding each image acquisition units 12 collects, cluster and filter unit 13 all will be confirmed the effective target of every two field picture in this consecutive image, and calculate the center of gravity of each effective target, therefore, after handling through cluster and filter unit 13, obtain the center of gravity of the effective target of every two field picture in one group of consecutive image of corresponding each image acquisition units 12.
According to an embodiment of present embodiment, this cluster and filter unit 13 comprise: clustering processing module 131, motion detection block 132, noise elimination module 133 and computing module 134, wherein:
Clustering processing module 131 is used for the described consecutive image information that gets access to according to each image acquisition units 12, and the target with same characteristic features is merged, and obtains a plurality of targets of every two field picture in the described consecutive image.
Wherein, present embodiment carries out clustering processing in carrying out the target deterministic process, is in order to reduce the number of image object, on the one hand, the processing of too many target is taken a part of resource; On the other hand, having the different target of same characteristic features in the image may light source feedback just just itself.The consecutive image that present embodiment photographs camera by the clustering processing module carries out clustering algorithm to be handled, and the pixel fusion of identical characteristics is integral, and reduces the number of target in the image.Wherein, Jing Dian clustering algorithm has based on watershed divide and fuzzy C-means clustering, based on K-Means cluster or the like.
In the present embodiment, by clustering processing, the spot noise that will much loose is fused to together, the indirect purpose that has played de-noising, and therefore, this clustering processing module 131 can also be removed large tracts of land interference noise or static background.
Motion detection block 132 is used for finding out moving target from described a plurality of targets.
In the present embodiment, after the target of having determined to exist, can also judge that each target is static or motion, therefrom finds out moving target, so that calculate the center of gravity of each moving target according to motion detection.
Wherein, motion detection can adopt classic algorithm, if promptly each pixel difference of consecutive frame is greater than a threshold value, and this pixel of present frame is in the smooth background after the de-noising, thinks that then this pixel is the motion pixel.In the present embodiment, owing to pass through clustering algorithm, be clustered into a plurality of targets in every two field picture, then motion detection is based on the consecutive frame target, rather than based on pixel.
Noise elimination module 133 is used for described moving target is carried out Filtering Processing, to confirm the effective target of every two field picture in the described consecutive image that each image acquisition units gets access to.
In the present embodiment, if image acquisition units 12 is to be used to gather with the refractive body image information of a plurality of telepilots of thing as a token of, then in the present embodiment, this noise elimination module 133 can be confirmed a plurality of effective targets.Wherein, corresponding telepilot of effective target.
In the present embodiment, when the camera collection image,, circuit, electromagnetism etc. can introduce various noises owing to disturbing, white Gaussian noise for example, be characterized in randomness and low light level epistasis, noise brings interference can for the processing multiple goal, so present embodiment carries out filtering by noise elimination module 133 according to the continuous multiple frames image information, select for use different Filtering Model to filter out corresponding noise.Wherein, noise elimination module 133 can adopt classical frame filter model, for example average value filtering, Gauss's low-pass filtering or the like, for example, in N successive frame, the barycentric coordinates of same target are p (i), the absolute value of adjacent barycentric coordinates difference is A (i), A (in)=| p (in)-p (in-1) |, if the mean square deviation of the A (i) of N continuous frame is then thought Gaussian noise less than a threshold value.
Computing module 134 is used to calculate the center of gravity of described effective target.
