Problems solved by technology
Due to its low cost and good effect, it is gradually becoming popular, but 3D street three-dimensional paintings are usually handmade, so the requirements for practitioners are very high, and it is difficult for ordinary people to grasp the accuracy of the final shape of the work, and it takes a long time, cannot be copied, and the fineness is poor

Embodiment Construction
[0037] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0038] refer to figure 1 , an embodiment of a method for making a 3D ground sticker of the present invention is proposed. The method includes:
[0039] S1 acquires scene data and determines a viewpoint;
[0040] The scene data includes the length and width of the two-dimensional plane ABCD and the coordinates of the observation point.
[0041] S2 acquires multiple two-dimensional images of embedded content;
[0042] Take pictures at different angles to obtain multiple two-dimensional images. Imagine the camera as an ideal pinhole camera, then the shooting point is the observation point for the best three-dimensional effect. The coordinates of the shooting point can be determined according to the camera parameters such as the focal length. It is the observation viewpoint for observing the best three-dimensional ef...

The invention provides a manufacturing method of 3D (three-dimension) ground stickers. The method comprises the following steps that scene data is obtained, and the optimum viewpoint is determined; a plurality of 2D (two-dimensional) images with contents are obtained; feature points of the 2D images are extracted, and the 3D effect images with contents are rebuilt; the feature points in the 3D effect images are projected to the actual scene, and the first layer of 2D plane graph with virtual 3D effects is formed through rendering stretching; the first layer of 2D plane graph is split into a plurality of small-block plane graphs to be cut, the small-block plane graphs are further rendered, and the second layer of plane graph is formed; and the two layers of 2D plane graphs are printed and are precisely pasted to obtain the 3D ground stickers. Products manufactured by the method can realize the effect of street 3D pictures, the precision is high, and in addition, the mass production can be realized.
Description
technical field [0001] The invention relates to a floor sticker, in particular to a method for making a 3D floor sticker. Background technique [0002] The technology of displaying three-dimensional images on a plane has more and more widespread applications, such as gratings and three-dimensional pictures. [0003] The grating is to print several images on different lines, corresponding to the width of each lens in the grating, and print them in rows on the back of the grating sheet in order. Since the observation angles of the two eyes on the grating are different, the two eyes will see to different images, resulting in a three-dimensional effect. However, differences in grating characteristics, types, specifications, thickness, size, and directionality have a great impact on the three-dimensional effect, and it is difficult to distinguish and choose in applications, and the price is relatively high. [0004] The 3D three-dimensional street painting originated from weste...
