[0002] Existing stereoscopic display systems require a projector to project the image onto a stereoscopic imaging device, and the light projected by the projector is a divergent real image. In order to obtain a 50cm×50cm real image, the optical path is required to be no less than 1m theoretically. Compared with the display system, it is very large, so the stereoscopic display system can only be installed in very large exhibition halls. In places with small spaces such as classrooms, laboratories or conference rooms, there is not enough space to install the stereoscopic display system. , this problem severely limits the application of stereoscopic display systems

Embodiment 2
[0088] The difference between this embodiment and Embodiment 1 lies in the method of cutting out the arrays a11, a21, a31 and a41 in the above step 202, and the method of combining a11, a21, a31 and a41 into the array a0.
[0089] The pixel size of the arrays a1, a2, a3, a4 is 640×480, and the pixel size of a0 is 640×640.
[0090] The specific steps of step 202 are as follows:
[0091] Step 20201, refer to Figure 13 , Extract the pixels from column e to column 640-e of row n in a1 Extract the pixels from column i+e to column 640-(i+e) of row n+i in a1, and in turn Execute until i+e=320 to get a11, i is an integer starting from 1, and e is any integer between 1 and 160;
[0092] Step 20202, rotate a2 clockwise by 90 degrees, extract the pixel points from row e to row 640-e of column 480-n in a2, and extract the pixels of row 480-(n+i+e) in column a2 Extract the pixels from line i+e to line 640-(i+e), and execute them sequentially until i+e=320, and get a21;

Embodiment 3
[0098] The above-mentioned embodiment 1 and embodiment 2 are for the case that the object to be imaged 9 is small in size and the image of the object to be imaged 9 can be contained in the array a11, when the array a11 of the isosceles right triangle cannot contain the image elements of the object to be imaged 9 , step 202 adopts the following method:
[0099] Cut out an array a11 containing the image of the object 9 to be imaged in a1. The upper part of the array a11 is a rectangle, and the lower part is an isosceles trapezoid with a wide top and a narrow bottom. The long horizontal side of the isosceles trapezoid is in line with the long side of the lower side of the rectangle Equal and coincident, the hypotenuse of the isosceles trapezoid is 45°, the upper long side of the rectangle is located at the nth row of a1 on the upper side of the image of the object 9 to be imaged, and the array a11 is also cut out in a2, a3 and a4 The arrays a21, a31, and a41 with the same shape a...

Abstract
The invention discloses a display method of a compact stereoscopic display system, which belongs to the technical field of three-dimensional display. including an image processing device (2), a projector (3) and a stereoscopic imaging device, the projector (3) is connected to the image processing device (2), and a mirror assembly is arranged between the projector (3) and the stereoscopic imaging device, The light from the projector (3) is projected on the stereoscopic imaging device after being reflected by the mirror assembly. A display method, comprising the following steps: extracting four images in four directions of an object to be imaged (9); cutting out the four images for cropping, and splicing them into a combined image; the projector (3) reflecting the combined image to a stereoscopic imaging device through a mirror assembly superior. Reflecting the light of the projector through the reflector assembly reduces the requirement of the optical path between the projector and the stereoscopic imaging device, which can make the display method of the compact stereoscopic display system compact in structure and small in size, and can meet requirements in classrooms and experiments. It can be used in places with small spaces such as office or conference room.
