Embodiment Construction

[0023] Embodiments of the end-of-sight estimation device according to the present invention will be described below with reference to the drawings.

[0024] In an embodiment of the present invention, the line-of-sight end point estimating device is applied to a vehicle driving assistance device installed in a vehicle. In order to inform the driver that there is an obstacle which he is unaware of, the driving assistance device according to this embodiment issues an alarm based on the positional relationship between the end point of the driver's line of sight and the obstacle.

[0025] The following will refer to Figures 1 to 5 The driving assistance device 1 according to this embodiment is described. figure 1 is a block diagram of the driving assistance device according to this embodiment. figure 2 An example of the positional relationship among the driver, the view video image camera, and the object according to this embodiment is shown. image 3 An example of a field of...

Abstract

A sight-line end estimation device (1) includes a sight-line direction detection portion (2) that detects a sight-line direction of a driver of a vehicle, a target object detection portion (4, 5) that detects the positions of target objects existing around the vehicle, a relative position acquisition portion (7) that acquires relative positional information between the driver and the target object detection portion, and a sight-line end estimation portion that estimates the driver's sight-line end by detecting a target object whose position detected by the target object detection portion lies substantially in the driver's sight-line direction detected by the sight-line direction detection portion.

Description

technical field [0001] The invention relates to a line-of-sight terminal estimation device for estimating the line-of-sight terminal of a driver. Background technique [0002] An end-of-sight estimation device has been developed that estimates where the driver's line of sight is directed in order to assist the driver. For example, the vehicle's line-of-sight estimation device detects the driver's line-of-sight direction, and detects the relative direction of each target (vehicle, person, etc.) existing around the host vehicle relative to the host vehicle, and compares the line-of-sight direction with the target Each of the relative directions of objects is compared to determine which target object the driver's line of sight points to, and to determine whether the driver is aware of the risk or danger (see (Japanese Patent Application Publication No. 2005-134971) (JP-A- 2005-134971)). [0003] In the above-mentioned end-of-sight estimation device, the position of the driver...
