Example Embodiment

[0040] Hereinafter, an embodiment of the present invention will be described with reference to the drawings, but the present invention is not limited to this embodiment. In addition, in the drawings described below, structures having the same functions are denoted by the same reference numerals, and overlapping descriptions may be omitted.

[0041] figure 1 It is a schematic diagram showing the compartment of the vehicle 100 equipped with the face detection device 1 according to the present embodiment. The vehicle 100 includes a face detection device 1 having an imaging unit 2. The face detection device 1 may be installed in any place in the vehicle 100. The face detection device 1 may be a stand-alone device, or it may be incorporated in another system (for example, a car navigation system) in the vehicle 100.

[0042] The imaging unit 2 is installed in the vehicle cabin in front of the driver's seat 101 (that is, on the traveling direction side of the vehicle 100). The imaging...

Abstract

A face detection apparatus (1) detecting a face from an image which is captured by an imaging unit (2) and includes the face, includes: a position detection unit (11) that detects a position of a face part of the face from the image; an initial state determination unit (12) that determines a model initial state on the basis of the position of the face part; and a model fitting unit (13) that generates a model of the face on the basis of the image by using the model initial state.

Description

technical field [0001] The invention relates to a human face detection device and method for detecting the position and orientation of a human face according to captured images. Background technique [0002] In recent years, the development of face detection technology that detects the position and orientation of the face included in the captured still image or moving image, and the state of facial organs (organs that make up the face) such as eyes and mouth, is being developed. progress. For example, in a vehicle, by detecting the driver's face, it is possible to detect distracted driving or drowsy driving, and perform predetermined actions such as a warning. [0003] Non-Patent Document 1 discloses a face detection technology (ASM: Active Shape Model; active shape model, AAM: Active Appearance Model; active appearance model) that fits a statistical face shape model using the steepest descent method or the like. The face in the image, that is, model fitting is performed, ...
