Concrete, in this embodiment, projector Conventional projection pixel is 1024*768, solves the technical problem that as required, namely video is mapped to and obtains, on irregular metope, the picture that visual angle is smooth. Accordingly, it would be desirable to first pixel to be carried out gridding matrix zoning. This matrix density can adjust according to actual needs. With 102*102 (namely now D takes 102) pixel for a matrix unit, it is possible to obtain horizontal a1-a10 row, longitudinally can obtain b1-b8 row (famous b8 behavior hemistich).
Owing to the pixel value that projector is total is to be limited to 1024*768, so the visual theory according to " near big and far smaller ", in 80 picture element matrix unit, the distance values of each range finding, more little apart from more remote picture element matrix area, more big apart from more near picture element matrix area. And the meansigma methods of minimum distance and maximum distance is not make pixel to change. So, the correction value of picture element matrix unit is equal to actual range divided by [(ultimate range+minimum range) is again divided by 2], then is multiplied by 102, it is simply that final matrix pixel values.
Recognition unit 400 can adopt noctovisor scan identification, distance value can be obtained by infrared ray, and in order to realize the easiest distance obtaining matrix, it is possible to designing an infrared matrix, the crevice projection angle that the infrared projection matrix of 10 heads is total is consistent with the projection breadth of the camera lens of projector. Such as, the imaging breadth of projection is 30 degree of angles, then, the arrangement of infrared matrix just carries out transversely arranged with 3 degree for a unit, so disposable obtains 10 groups of distance values, and then longitudinally amount 8 times once again, had both obtained the numerical value of 80 groups of distances.
The central point distance that the central point distance of such as a1b1 matrix unit is d1, a2b2 matrix unit is d2, and the central point distance of a80b80 matrix unit is d80 by that analogy. 80 numerical value so obtained just very easily read the maxima and minima of distance. So obtain the maximum that meansigma methods is exactly distance and add minima again divided by 2. The pixel of intermediate value matrix unit does not become 102*102, and the pixel value of other matrix units just can obtain corresponding change according to formula above. Total principle is exactly near big and far smaller, more big apart from more near matrix unit pixel value, more little apart from more remote matrix unit pixel value. Then passing through Mesh Smoothing technology, the irregular metope that projects to just obtained under original 1024*768 pixel limits obtains the purpose of the regular image that visual angle takes.
