I hope to be able to realize my original designs from over 20 years ago in 2019.
The requirements for all of these events are very similar, groups performing choreographed, clustered movements, with the ability to measure the spatial position and precise trajectory of every person on the field in real time, continuously, and without contact, at every instant in the actual field. The data obtained from the measurement will be automatically edited and processed in the form of secondary images, and the measured dynamic images will be forwarded to the wearable devices of each player in the field in the form of immediate feedback. Another task of the measurement and control system is to perform calculations based on pre-specified parameters for the overall movement of the team, e.g., at what absolute time a formation of students is scheduled to arrive at a specified geographic landmark on the east side of the principal's podium, and at what absolute time the formation of students is scheduled to leave a certain geographic landmark on the west side of the podium. In this way, a continuous, animated, virtual scene reflecting the speed of travel is projected, and each frame within this scene includes the ideal geographic location of each student. This scene is also immediately forwarded to each student in the queue.
Each student in the queue, in his or her own wearable device, can simultaneously observe two images superimposed on top of each other, which are distinguished by different colors. Each student in the queue then immediately knows how he or she should correct his or her position on the move, including the next change in walking direction deviation, gait adjustment, and change in walking speed.
So, this system establishes the cooperation and tacit understanding between each student in the queue.
For group dance performances and sports, there are also physical details that require a system of measurement of the body's movement posture and a system of command of the ideal body posture.
This system can command the group exercise performance in real time, realizing the flow, blooming, gathering, spreading, deformation, distortion, shrinking, enlarging and other performance effects of the group figure.
This is the traditional, inherited, ancient, and generations of training methods can not be realized. In the past, the training method, the construction of ordinary graphic changes, have to practice summer heat, winter training several winter, for a long time of professional training, taking up the student's valuable youth time. Moreover, the training of these graphic changes does not have any "sustainable development significance", and is only dedicated to a performance that will not be repeated.
The most striking innovation of this method is that it can be a VIP, a client who pays for the sponsorship, an impromptu poem, a fugue, an orchestra's impromptu performance, an impromptu change in the mood and posture of the lead dancer, a recitation of the staccato and staccato, and then immediately generate the matching command graphics, and immediately realize it in the vast field.
For the impromptu conversations between guests and hosts, for the dialogues between the actors, for the declaration of love vows, the continuous change of formation is used to interpret.
The same system can be used for clustered formation performances in the air by unmanned aircraft.
This is a milestone in the revolution of the performing arts. These effects are described in more detail in the "guided fireworks" and "guided pyrotechnics" already available on the Internet.
The author of this article proposed the design of the music conductor in 1980, which was implemented in Japan only in 1995. The authors of this paper worked on the "force feedback keyboard" before the reform and opening up of the country, and all of the above are closely related.
More detailed information has been sent to ten of the most famous key virtual reality research organizations, China's leading news agencies.
The neatness of the formation is relative, the untidiness of the formation is absolute.
In today's era, drill, square dance is also going to use AR, VR, WR glasses and helmets, which can be black technology, yo.
The public has seen the drone remote control of the screen in the screen and the space launch control hall of the screen, showing a lot of movement trajectory parameters. For the above group performance, for each performer, there is their own independent set of trajectory parameters, in addition to a set of parameters related to the overall movement of his movement, see this system is not "pediatric" Yes.
The motion trajectory should be represented by a wide range of data, in addition to the absolute geographic coordinates of the current moment, but also the previous coordinate parameters, linked to each other, which can represent the "motion trajectory".
For this kind of open-air, large-area places, it is impossible to lay sensors on the ground to detect the actor's trajectory; ultrasonic attenuation in the air, short propagation distance; microwave radar resolution is low here, high precision terahertz radar is under development, currently does not meet the requirements of the large-scale on-site detection; radio tags, differential GPS, radio frequency ranging system is not practical; lidar scanning speed is low. Practical; LIDAR scanning speed is low; portable, high-precision, low-drift inertial instrumentation system has not yet been localized; satellite ingested images are subject to the resolution, transmission delay, data analysis and finishing time is long; unmanned aircraft in the air to shoot, the first requirement for the unmanned aircraft's trajectory to carry out accurate measurements, and then for the unmanned aircraft carrying the camera space attitude to Measurement, the whole data processing process is very large; only visible light camera is suitable and useful.
Of course, in rainy, snowy, hazy environments, the visible-light camera system's capabilities are drastically reduced.
In the adversarial military realm, the acquisition of targets in battlefield space is even more difficult.
People expect, in the hostile, the requirements of the hidden battlefield, high-speed, real-time completion of the battlefield terrain, the enemy and our position, the two sides of the military layout and so on the measurement of the battlefield environment, effective and rapid surveying of the terrain, with the other on-site situational awareness measurement system, quickly in the battlefield to unfold for the combat troops, to provide tactical support, manpower command support. Active advance with the enemy combat decision-making time, shorten the opponent's passive decision-making time.
