Development of throw type automatic photographing device

In disaster, it is important to photographs and video from the sky. Aerial photographing devices such as helium gas balloons and helicopters have ever been used for information gathering activities at that time. However, these devices have a high risk because they are strongly affected by air stream at low airspace. As the new photographing device improving the above problem, in this paper, we have developed a throw type photographing device packaged in a plastic capsule egg, and proposed an automatic photographing system. The photographing device is controlled by the control circuit with an accelerometer and takes a photograph when it reaches the top of air. The accelerometer is used to calculate the time that the device until photographing. Moreover, we take aerial photographs in practice and show the effectiveness of the proposed system.
