experiment analysis

In order to verify the feasibility of the above-mentioned device to achieve "bullet time" shooting, this experiment selected smoke and feathers as the experimental objects, and conducted the following experiments:

by the formula It can be calculated that the diffusion rate of the gas whose main component is _CO2 is about 362m/s under standard conditions. Under this diffusion rate, the shooting effect of "bullet time" can hardly be seen at a low speed of 70rpm, and the effect of perspective change and time stillness No special effects were apparent. When using a high speed of 150rpm, you can feel the effect of slowing down time. However, if you use a high speed, the camera will lose frames and the picture will freeze. Therefore, increasing the number of shooting frames accordingly will make the shooting effect better.

Feathers fall at an average speed of 1m/s due to air resistance. At this time, the high-speed shooting highlights the blurring of the surrounding environment and the shooting object, and the picture is chaotic. The shooting effect can be achieved by using low speed.
