Apparatus detecting driving incapability state of a driver includes: a head detection portion that successively detects a head portion, which is higher than a neck of the driver, based on an image of a driver's seat captured by an imaging device mounted in a vehicle; and an out-of-frame state detection portion that detects that the driver is incapable of driving, when the head portion detected by the head detection portion is out of a predetermined scope in the image during travelling of the vehicle.

Apparatus detecting driving incapability state of driver

A feature point position estimation device is provided. The feature point position estimation device includes a subject detection section for detecting a subject region from a subject image, a feature point positioning section for positioning a feature point at a preliminarily prepared initial feature point position with respect to the subject region, a feature amount acquisition unit for acquiring a feature amount of the feature points arranged, a regression calculation unit for calculating a deviation amount of a position of a true feature point with respect to the position of the feature point by performing a regression calculation on the feature amount, and a repositioning unit for repositioning the feature points based on the deviation amount. The regression calculation unit calculates the deviation amount by converting the feature amount in a matrix-resolved regression matrix.

An apparatus detecting driving incapability state of a driver includes: an inclination detection portion that detects inclination of a head of a driver with respect to a trunk of the driver lower than a neck, based on an image of a driver seat captured by an imaging device mounted on a vehicle; and a posture collapse detection portion that detects the driver is incapable of driving when the inclination of the head detected by the inclination detection portion is greater than a relative inclination threshold during travel of the vehicle.

An apparatus detecting driving incapability state of a driver includes: a head detection portion that detects a head of the driver based on an image of a driver's seat captured by an imaging device mounted on a vehicle; and a shake detection portion that detects the driver is incapable of driving when an amplitude of a shake of the head detected by the head detection portion is smaller than a first amplitude or larger than a second amplitude, which is larger than the first amplitude, before a shake determination time elapses after external force has been applied to the vehicle during travel of the vehicle.

An in-vehicle control apparatus performs a hazard avoidance process. The in-vehicle control apparatus includes an anomaly determination section, an alarm control section, and a hazard avoidance control section. The anomaly determination section determines whether a driver is under driving inability state during travel of the vehicle, based on information on monitoring of state of the driver. The alarm control section activates an alarm annunciator to issue an alarm outwardly from the vehicle when the driver is determined to be under driving inability state. After the alarm annunciator starts the alarm, the hazard avoidance control section fails to perform the hazard avoidance process when the alarm is stopped by a manipulation of the driver and performs the hazard avoidance process when a specified time elapses under state where the alarm is not stopped since the starting of the alarm.

In-vehicle control apparatus

A countour detecting apparatus which comprises: a picture-data input device for the input of data on a picture including an object to be detected; a video-signal generator for scanning the data on the picture and generating video signals each corresponding to luminance of each pixel of the picture; a picture-data memory for sampling the video signals corresponding to each of two-dimensional coordinates of the pixels and storing the sampled video-signals; and a contour detector for moving a pair of a first picture section and a second picture section, which is arranged to be apart by a predetermined distance from the placed in parallel with the first picture section, in the picture stored in the picture-data memory, the countour detector also detecting the position of the first and second picture section in case where the absolute value of the difference between a first sum of the video signals stored in the picture-data memory corresponding to the pixels in the first picture section and a second sum of the video signals stored in the picture-data memory corresponding to the pixels in the second picture section is maximum. Thereby, even when a picture including an object is not clear, the contour of the object can be surely detected. Further, the period of time required for processing of detection of the contour of an object can be substantially decreased.
