  • Patent number: 11027746
    Abstract: A driver state determination unit of a drive mode switching control device regularly or irregularly determines whether a driver's state is a state of being able to perform a driving operation in a manual drive mode. The drive mode switching control device determines whether an operation performed by the driver is an emergency override operation or a non-emergency override operation. The drive mode switching control device outputs a switching signal for switching an automatic drive mode to the manual drive mode when a determination result by the driver state determination unit immediately before detection of the emergency override operation is that a driver's state is a state of being able to perform a driving operation in the manual drive mode.

  • Patent number: 10521917
    Abstract: Tracking a target object to be tracked included in a plurality of consecutively captured images is performed by an image processing apparatus. The image processing apparatus comprises an image acquisition unit and a tracking unit. The image tracking unit is configured to acquire an image. The tracking unit is configured to detect a target object to be tracked included in the image by matching and acquire over a plurality of the images an amount of movement of the target object to be tracked and a direction of the movement of the target object to be tracked. The tracking unit performs first matching by using a first template corresponding to the target object to be tracked, and performs second matching by using a second template, which is different in size or shape from the first template, in a case where a score of a result of the first matching is lower than a first threshold value.

  • Publication number: 20190318151
    Abstract: In a state where a tracking flag is on, a search controller determines, with respect to a previous frame, whether an amount of change in positional coordinates of a feature point of a face in the current frame is within a predetermined range, whether an amount of change in face orientation is within a predetermined angle range, and whether an amount of change in sight line direction is within a predetermined range. When the conditions are satisfied in all these determinations, the change in the detection result in the current frame with respect to the previous frame is considered as being within an allowable range, and continuously in a subsequent frame, detection processing for a face image is performed in accordance with a face image area saved in a tracking information storage unit.

  • Publication number: 20190318485
    Abstract: During tracking, a rough search is performed on a face image area detected in a current frame, and when the reliability of the result of the rough search is equal to or smaller than a threshold value, a value obtained by multiplying a reliability of a rough search result detected in one previous frame by a predetermined coefficient is set as a new threshold value, and it is determined whether or not the reliability of the rough search result detected in the current frame exceeds the newly set threshold value. Then, when the reliability of the rough search result exceeds the new threshold value, the decrease in reliability of the rough search result is considered as temporary, and a tracking flag is kept on while tracking information is also held.

  • Publication number: 20190318152
    Abstract: In a reference position determination unit, for example, a plurality of feature points of eyes and a nose of a face are detected by rough search from an image area including a driver's face extracted by a face area extractor with a rectangular frame. Based on the feature points of the respective organs, a position between eyebrows of the driver's face is detected, and this is determined as a reference position of the face. Then, a face area re-extractor corrects the position of the rectangular frame with respect to image data so that the determined reference position of the face is the center of the rectangular frame, and an image area including the face is re-extracted from the image data by using the rectangular frame in the corrected position.
