The present invention utilizes the wall in the tunnel of setting about from driver's speed perception of apparent movement motion theory that the control tunnel speed of a motor vehicle of apparent movement grating is set; The grating that produces the apparent movement motion is set on the tunnel wall; And the in the opposite direction of apparent movement travel direction and vehicle ' is set, makes driver's perception velocities increase.
Utilize the apparent movement motion theory that grating (grating is meant that the amplitude or the phase place that can make incident light receive the periodically optical element of spatial modulation) is set on the tunnel wall; Influence the principal element of apparent movement movement effects through control; Instant apart from (SOA, stimulus onset asynchrony) and spacing (SIS, stimulus separation); The driver is produced be judged as the apparent movement motion perception of " stable motion in the same way ", thereby confirm the space layout of the proper form of apparent movement motion.
Difference to the former studies experimental situation; Through 3DMAX made under the tunnel environment based on the driver visual angle change video with the reverse apparent movement grating of vehicle forward direction, ratio this index of taking to be judged as " stable motion in the same way " is confirmed the proper form that apparent movement moves.
Result through to 6 men, 2 women observation experiments analyzes, and finds that space layout is two bright two dark, four bright four dark, and spacing is 2m, 4m, the time apart from be 60ms, 120ms, 180ms, the ratio that is judged as " stable move in the same way " during 240ms all is higher than 95%.In view of the above, made under 16 kinds of situation car respectively with 60km/h as proper form with above-mentioned 16 kinds of combinations, 90km/h, the video that the speed of 120km/h is gone in the tunnel takes forced choice method design subjectivity to be equal to 282 groups of speed experimental programs.Result through to 6 men, 2 women observation experiments analyzes; Find that the grating space layout is two bright two dark; The time apart from being 60ms; Experimenter's when spacing is 4m perception velocities is maximum, and this moment 8 experimenter's perception velocities standard deviation less, so with this form as the optimised form that is used for the apparent movement grating that the speed of a motor vehicle controls.
Prove through experimental study: space layout, SIS, SOA all exist significantly the apparent movement perception to be influenced (p-value 0.01).Can find out from the result of Fig. 5, Fig. 6 and Fig. 7; When the apparent movement grating adopts light and dark, no matter spacing with the time apart from what be, the ratio that the observer is judged as " stablize in the same way and move " is all very low; All be lower than 50%, be judged as " flashing " perhaps " unsteady motion " more this moment; When the apparent movement grating adopts two bright two dark with four bright four when dark; The ratio that the observer is judged as " stable motion in the same way " significantly improves; The ratio that is judged as " stable motion in the same way " this moment changes along with the variation of SOA and SIS, when SIS is 2m, 4m, can both obtain stable motion perception in the same way when SOA is 60ms, 120ms, 180ms, 240ms; The ratio that be judged as " stable motion " in the same way this moment all is higher than 95%, and the experimental result of this and Wei Tehaimo is different.The ratio that when spatial separation is 6m, 8m, is judged as " stable motion in the same way " reduces gradually.According to this experimental result, choose space layout and be two bright two dark, four bright four dark, SIS is 2m, 4m, SOA is 60ms, 120ms, 180ms, the stimulus of 240ms is as the proper form of apparent movement motion.
All there are appreciable impact (p-value < 0.01) in space layout SIS, SOA to speed perception.Can find out from the result of Fig. 8, Fig. 9; Under two dark two bright and four dark four bright situation; Apparent movement grating on the tunnel wall all can cause over-evaluating of the speed of a motor vehicle, and shows under the identical situation of identical characteristic: SIS, along with SOA reduce over-evaluate effect and progressively amplify.Under the identical situation of SOA, SIS is more little, and then to over-evaluate effect big more.Yet respectively to two dark two bright and four dark four understand following 8 experimenters of condition experimental result carry out variance analysis and obtain; The standard deviation of four bright four 8 experimenter's speed perception when dark is greater than two bright two dark situation, explains that four bright four observers' when dark speed perception differs greatly.60 (2) the expression speed of a motor vehicle are 60km/>h among the figure, and spacing is 2m, and other in like manner.
Table 1 has been listed the apparent movement movement velocity under different SOA and the SIS situation, and when SIS was identical, the more little then apparent movement of SOA movement velocity was big more.Can find out that from testing 2 result the more little then perception velocities of SOA is big more, this comes down to the influence of apparent movement movement velocity to perception velocities.
