The visual analysis comprises three parts of horizontal visual field analysis, vertical visual field analysis and visual field coordination analysis. From the visual psychology, research and analysis are carried out on the spatial line shape of the road, the coordination between the spatial line shape of the road and the surrounding natural landscape and the coordination between the spatial line shape of the road and buildings along the line, and the like, so as to keep the continuity of vision, and the comprehensive design that the driving has enough comfort and safety is called as visual analysis. Horizontal field analysis studies the lateral width of the facility and the depth distance of the space. And scientifically determining that the central visual angle within 10 degrees of the horizontal visual area is the optimal visual area. Human eyes are instantaneous visual zones within the range of 20 degrees of the central visual angle, and can identify objects in a very short time. Human eyes have an effective visual area within 30 degrees of a central visual angle, and can distinguish the image of an object by focusing attention. Human eyes have a maximum visual area within 120 degrees of a central visual angle, and a great deal of effort is required to identify an object. If the head is rotated, the maximum viewing range of the person can be up to 220 °. The objects of the vertical field of view analysis study are the height of the object and the depth of penetration of the overall planar configuration. According to scientific determination, the optimal visual area of the human eyes in the visual area in the vertical direction is 10 degrees below the visual plane, the good visual area is from 10 degrees above the visual plane to 30 degrees below the visual plane, and the maximum visual area is from 60 degrees above the visual plane to 70 degrees below the visual plane.

Next, a further explanation of the specific structure of the trampoline safety protecting platform of the present invention will be made.
In the trampoline safety protection platform:
the position judgment device is also used for sending a second driving instruction when the human body imaging area detected in the directional blurring image does not have partial image content outside the square pixel window.
In the trampoline safety protection platform:
and the extension driving mechanism is also used for retracting the four spare elastic net body structures to be right below the elastic net body when receiving the second driving instruction.
In the trampoline safety protection platform:
four spare elastic net bodies right below the elastic net body have the same structural size and have sieve pores with the same pore size.
The trampoline safety protection platform can further comprise:
and the sound-light warning mechanism is arranged near the elastic net body, is connected with the position judgment equipment and is used for executing sound-light alarm operation corresponding to the first driving instruction when receiving the first driving instruction.
The trampoline safety protection platform can further comprise:

wherein the video communication device comprises compression encoding means for performing MPEG-4 standard compression on the live image to obtain a compressed image.
In the trampoline safety protection platform:

In the trampoline safety protection platform:
the video communication device comprises a wireless communication interface connected with the multi-index coding device and used for wirelessly transmitting channel coding data.
In the trampoline safety protection platform:
the wireless communication interface is a time division duplex communication interface or a frequency division duplex communication interface;
or the wireless communication interface is a 4G communication interface or a GPRS communication interface.
Also, to overcome the above disadvantages, the present invention provides a method of trampoline safety including using a platform as described above to provide a corresponding emergency when the current position of a person above the trampoline is out of the area of the resilient net body of the trampoline.
In addition, frequency division duplex means that uplink and downlink transmissions are performed on different frequencies. In the first and second generation cellular systems, FDD technology is basically used for duplex transmission. In particular, in the first generation cellular systems, since continuous baseband signals are transmitted, duplex uplink and downlink channels must be provided using different frequencies. In the first generation cellular systems, in which FDD is used for continuous information transmission, frequency synthesizers for generating different carrier frequencies are required at both the transmitting and receiving ends, and a duplex filter for preventing the transmission signal from leaking to the receiver is required at the receiving end. In addition, in order to facilitate the fabrication of the duplexer, a certain frequency interval is required between the transmission and reception carrier frequencies. In the second generation of systems such as GSM, IS-136 and IS-95, FDD technology IS also used. In these systems, since the information is transmitted in time slots, the transmission and reception can be performed in different time slots, and the transmission signal of the mobile station or the base station does not interfere with the receiver. So, despite the FDD technique employed, no expensive duplex filters are required.
The FDD mode is characterized by receiving and transmitting in two symmetric frequency channels separated (190 MHz between uplink and downlink frequencies), and separating the receiving and transmitting channels by guard bands.
By adopting the technologies of packet switching and the like, the bottleneck of the second generation development can be broken through, the high-speed data service can be realized, the frequency spectrum utilization rate can be improved, and the system capacity can be increased. FDD must provide third generation services using paired frequencies, i.e., within a bandwidth of every 2x5 MHz. The mode can fully utilize the uplink and downlink frequency spectrums when supporting the symmetric service, but the frequency spectrum utilization rate is greatly reduced (about 40 percent of the frequency spectrum utilization rate is reduced due to low uplink load) when the asymmetric packet switching (Internet) works, and in this regard, the TDD mode has incomparable advantages compared with the FDD mode.
