Summary of the invention
1, the above-mentioned background technology is made up, designs, optimizes;
2, tunnel advertisement is a kind of animated advertising that alight case, luminous plaque or luminophor are set in the railway tunnel that light source (or than weak light source) is not set.
(1) this railway tunnel refers to and generally has at the uniform velocity, spares and slow down, spare and quicken the subterranean railway tunnel, city that passenger vehicle passes through; Between the light rail Close Tunnel; The railway tunnel interval.
(2) so-called animation is according to physics motion relativity principle: picture is pressed passenger vehicle travelling speed and above-mentioned (at the uniform velocity, even quicken, the even deceleration) forms of motion, presses the width of cloth number and the corresponding spacing setting that are drawn in design in the regular hour.Be detained principle (being that image staying was generally 0.1 second in the time of onlooker's impression) according to image by vision, the method that picture is made by cartoon, one group of continuous animation cut apart be fixed on tunnel-side, the passenger is in the compartment of motion, luminophor is in the tunnel of dark, being easy to concentrating of viewpoint, is exactly a width of cloth animation in passenger's eye.
(3) tunnel animation advertisement is different from cartoon.The artistic effect requirement of cartoon, the many more pictures of picture per second width of cloth number are coherent more, and general per second 24 width of cloth have special artistic effect but be less than under 24 width of cloth situations at per second.The characteristics of tunnel animation advertisement are that picture is fixed, and onlooker motion if the passenger vehicle travelling speed is low excessively, can not produce animation effect, under the low especially situation of speed, and the picture making of can't arranging, animated advertising is meaningless.
(4) if this technology and the long-range replacing control technology of lamp box picture are combined, can have more practicality and economic benefit.
3, picture spacing and computing formula
(1) design of picture spacing if make requirement by cartoon, is the relation of time and picture, be to occur being interrupted picture (passenger looks that action is continuous) in the unit interval uniformly, and enough fast speed is arranged, and people during this period of time see it being continuous animation effect.
(2) computing formula (uniform motion):
A number of pictures=unit interval number of pictures (per second width of cloth number) * finish animated advertising required time (second)
B picture spacing=passenger vehicle unit's movement velocity (per second rice) ÷ unit interval number of pictures (per second width of cloth number)
Example: certain company's issue tunnel animation advertisement, the time is 10 seconds, per hour 60 kilometers of passenger vehicle travelling speed, under the uniform motion condition:
A number of pictures=4 * 10=40 (width of cloth)
B picture spacing=16.67 ÷ 4=4.17 (rice)
4, the picture size is relevant with passenger's vision, and compartment distance dependent:
(1) advertisement picture can be different shape (plane), and still, rectangle has best adaptability;
(2) relevant with the vehicle window size, general, the passenger of too small vehicle window the inside can not see the view picture picture, and its advertising results are inevitable bad;
(3) with the distance dependent of picture at a distance of the compartment, the close together picture can not be too big greater than vehicle window, under opposite extreme situations, even, can not be greater than vehicle window;
(4) have only the track traffic can be with fixed distance, so satisfy this required distance.
