Embodiment Construction

[0042] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0043] figure 1 It is a block diagram showing one embodiment of the drunk driving prevention system to which the present invention is applied. figure 1 The drunk driving prevention system 101 is configured to include an alcohol sensor 111 , a camera 112 , an on-vehicle sensor unit 113 , and a drunk driving prevention device 114 .

[0044] The alcohol sensor 111 is a sensor for measuring the alcohol concentration in a person's breath, and supplies a signal indicating the measured alcohol concentration to the measurement result determination unit 151 of the drunk driving prevention device 114 . and, if figure 2 As shown, an LED 181 is provided on the outer surface of the alcohol sensor 111, and when a person to be measured for alcohol concentration measurement (hereinafter referred to as alcohol test) breathes into the alcohol sensor 111, the LED 181 blinks in a predet...

Abstract

The present invention provides a detector and a method thereof. The detector can reliably prevent the imposter which is different from the driver for measuring the alcohol concentration. A detected person image obtaining part (152) obtains the face image of detected person, namely the image of detected person when an alcohol sensor (111) measures the alcohol concentration. Furthermore the image of detected person is provided to a face checking part (162). A driver image obtaining part (161) obtains the face image of driver, namely the driver image which is shot in a specified time before or after the measuring of alcohol concentration. Furthermore the driver image is provided with the face checking part (162). The face checking part (162) checks the checked person with the driver according to the image of detected person and driver image for determining whether the detected person is the driver. The detector of the invention can be applied to the vehicle-mounted after-drinking driving preventer for instance.

Description

technical field [0001] The present invention relates to a detection device and a method thereof, and in particular to a detection device and a method thereof for detecting an imposter who is different from a driver for alcohol concentration measurement. Background technique [0002] Conventionally, a technique has been proposed in which when a predetermined timing is reached after the driver is authenticated first, or when the seat switch of the driver's seat is changed from off to on after the door of the vehicle is opened and closed, the ignition switch is turned on and off. When changing from off to on, or when the seat belt switch on the driver's seat is on, the driver's face is photographed and compared with the pre-registered face image, thereby detecting an impostor of the driver ( For example, refer to Patent Document 1). [0003] [Patent Document 1] Japanese Unexamined Patent Publication No. 2004-276783 [0004] However, in recent years, frequent serious accidents...
