Problems solved by technology
[0006] The large-scale spatial positioning system introduced above is generally implemented by combining infrared marker points into patterns, and identifying patterns through image processing methods to use the information represented by different patterns to achieve positioning purposes, but this method is too complicated to encode and requires a large amount of calculation. , cannot achieve real-time, and cannot meet the requirements of a large-scale video space
Especially when the image collected by the camera is distorted, the calculation error is often large, and the positioning cannot be realized

[0030] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0031] figure 1 Partition encoding map for infrared landmarks. Divide the video space into several square partitions of the same size, each partition contains a different number of dot-shaped marker points, and one infrared LED is a marker point.
[0032] The minimum distance between partitions is greater than twice the maximum distance between marker points within the partition, to avoid partition recognition errors in the case of image distortion, that is, to divide infrared marker points that are not in the same partition into the same partition.
[0033] The number of infrared landmarks in each partition represents the attributes of the partition, that is, if there are ...

The invention provides an infrared mark point partition coding and recognition method applied to a wide-range video space object positioning system to solve the problem of large positioning difficulty, slow speed and low accuracy under the condition of wide-range video space. The infrared mark point partition coding method comprises utilizing infrared LEDs (light-emitting diodes) to form a plurality of square partitions, wherein the number of the infrared LEDs in every partition represents the area attributes of the partition and the space coordinates of every partition are represented by the average space coordinates of the all the infrared LEDs in the partition. The infrared mark point partition recognition method comprises recognizing the number of the infrared LEDs in every partition and calculating the image coordinates of every partition in a video, wherein the image coordinates of every partition are represented by the image coordinates of all the infrared LEDs in the partition, and utilizing the area attributes of every partition to enable the image coordinates of every partition to correspond to the space coordinates. The space coordinates of a target point is calculated through the application of a quaternion resection algorithm, and accurate space video positioning can be achieved.
Description
[0001] 【Technical field】 [0002] The invention relates to a novel infrared marker point partition coding and recognition system, which is suitable for shooting target tracking in large-scale video space, especially suitable for shooting target positioning in large-scale interactive screen games. [0003] 【Background technique】 [0004] Target positioning technology in large-scale video space is the foundation and key technology of shooting games, optical tracking and virtual reality systems, among which positioning speed and accuracy are the primary conditions for realizing positioning in large-scale video space. Real-time, high-precision video spatial positioning technology is widely used but difficult to realize. At present, multi-sensor fusion technology is mainly used at home and abroad to achieve target positioning in a wide range of space. However, this type of technology is relatively expensive and is mainly used for commercial use in high-tech industries. It has not be...
