Problems solved by technology

For example, there will be the following false detection problem: when only the left half of the face is irradiated with sunlight and the partiality change is caused, the dark part that is not irradiated by sunlight cannot be recognized as a face, but only the bright part is detected. for the face contour

Abstract

Provided are an image processing method, an image processing system, an image processing device and a computer program for detecting a detection object such as nares of the driver with a high degree of accuracy in, for example, a system using an in-vehicle camera which is mounted on a vehicle and takes an image of the face of the driver. A detection object is diversified by a variety of detection methods such as a method for detecting a plurality of locations in the vertical direction as candidates during image pickup of an image, detecting a range to be a candidate of a detection object on the basis of the brightness of a pixel for each of rows of pixels lined up in the horizontal direction corresponding to each detected location and specifying a detection object from candidates of a detection object on the basis of the length of the detected range.

Description

[0001] technology area [0002] The present invention relates to an image processing method for detecting a specific detection object from a two-dimensional image obtained by arranging pixels in different first and second directions, an image processing device to which the image processing method is applied, and a The image processing system of the image processing device and the computer program for realizing the image processing device particularly relate to an image processing method, an image processing device, an image processing system and a computer program capable of improving the detection accuracy of a detection object. Background technique [0003] As a device for assisting the driving of vehicles such as automobiles, an image processing device has been proposed in which a driver's face is photographed by an on-vehicle camera arranged at a position where the driver's face can be photographed, and based on the obtained image, Image processing for detecting the outlin...
