Detection of driver's posture in the car by using far infrared camera
Various measurement equipments are used for the detection of the driver in a car, such as a CCD camera, an infrared camera, and a depth sensor. The space of the car is narrow so that it limits driver's action. We can expect that the driver can stay in one position in order to capture the image. But captured image can be easily influenced from the environment, such as the outside scene and illumination. The capturing method, which is suitable for detecting person in such environment, needs to be considered. First, we investigated the character of the light wavelength used for capturing. And then we examined the capturing method which is suitable for detecting in a car. Finally we acquired the information of driver with the proposed method and detected the driver's posture by performing image processing.
