Slit Type One-Dimensional Brightness Distribution Sensor

As aging society problem goes serious, systems to confirm to safety of elders in daily life are expected. In this paper, a sensor, which detects person localization without privacy offending, applying brightness distribution is proposed. In the proposed design, the sensor is constructed with a line sensor and slit to obtain one-dimensional brightness distribution. The proposed sensor is able to obtain one-dimensional brightness distribution that is approximately equal to integration value of each vertical pixel line of two-dimensional image. By employing this method, the information of the target's position and movement status can be obtained without using two-dimensional detail texture image. In this paper, the effectiveness of the proposed method is confirmed by experiments.
