Problems solved by technology

This situation is called misfitting, and when misfitting occurs, the accuracy of the face model decreases
In particular, it is easy for the position of the model's eyes to converge incorrectly on the frame of the glasses or the position of the eyebrows

Embodiment Construction

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

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

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

Abstract

Provided are a face detection device and method capable of improving the accuracy of a face model. A human face detection device (1) according to an embodiment of the present invention includes: an imaging unit (2), which captures an image including a human face; a position detection unit (11), which detects the position of human facial organs from the image; A state determination unit (12) determines an initial state of the model based on the positions of facial organs; and a model fitting unit (13) generates a model of a human face based on an image using the initial state of the model. The initial state determination unit determines a face position and a face angle using the eye position and the nose position acquired by the position detection unit, and determines an initial state of the model based on the face position and the face angle.

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, ...
