Problems solved by technology

[0004] The technique of Publication No. JP-A 2009-220631 has problems in that a separate lamp must be added in order to warn the driver and / or pedestrians, the cost of the equipment increases, and the volume required to install the equipment on the vehicle increases
Also, sometimes, in situations where the driver is driving absent-mindedly, the driver fails to notice the pedestrian simply by having the headlights projected onto the pedestrian
[0005] In addition, the technique of Publication No. JP-A 2008-299779 has a problem that although it uses the cockpit light to notify the driver that the moving body is approaching, it is difficult for the driver who is fixed in front to notice the lighting of the cockpit light

[0041] Such as figure 2 As shown, the projection system 10 relating to the first embodiment of the present invention is equipped with an image capture device 12 that captures an image of the area in front of the host vehicle, a vehicle speed sensor 14, a computer 16, and a headlight projection device 26, The vehicle speed sensor 14 continuously detects the speed of the host vehicle, and the computer 16 controls the headlight projection device 26 based on the front image captured by the image capture device 12 and the vehicle speed detected by the vehicle speed sensor 14. 26 Casting a ray in front of the host vehicle. The projection system 10 is installed in a vehicle (not shown).

[0042] The image capturing device 12 is equipped with an image capturing section (not shown in the drawing), an analog-to-digital conversion section (not shown in the drawing), and an image memory (not shown in the drawing), the image capturing section being configured by a monocular ca...

[0091] Next, a second embodiment of the present invention will be described. It is to be noted that the projection system 10 regarding the second embodiment has the same configuration as that of the first embodiment, so description thereof will be omitted.

[0092] The difference between the second embodiment and the first embodiment is that the motion detection part 22 detects the relative motion of the pedestrian, and based on the detected relative motion of the pedestrian, the control part 24 controls the headlight projection device 26 to correspond to the relative position of the pedestrian. change to change the position of the moving projection pattern and project the moving projection pattern.

[0093] For example, in a case where a pedestrian suddenly jumps onto the road while the host vehicle is running, it is necessary to project a moving projection pattern corresponding to a change in the relative position of the pedestrian. In the second embodiment, the motion dete...

Abstract

A projection system and a projection method are disclosed. The projection system includes: a position detecting section that detects the position of a target object located in front of a host vehicle; and a control section which, on the basis of the position of the target object detected by the position detecting section, controls a headlamp so as to project a projection pattern onto the position of the target object. The projection pattern moves in a direction corresponding to the direction of motion of a background at the position of the target object or a direction corresponding to the opposite direction of the direction of motion of the background.

Description

technical field [0001] The present invention relates to a projection system and a projection method, and in particular to a projection system and a projection method for controlling a headlight. Background technique [0002] Conventionally, there has been known a vehicle headlight device that can easily control the direction in which light is projected on a road shoulder, in this way it can warn at least one of a driver and a pedestrian (for example, Japanese Patent Application Laid-Open No.: JP-A2009-220631). [0003] In addition, a mobile body approach notification system is known that can give notification of the presence of an approaching mobile body that is difficult to notice with a simple and easy configuration (so that the driver can easily understand it in a perceptual manner) (Kokai Publication No. : JP-A2008-299779). [0004] The technique of Publication No. JP-A 2009-220631 has problems in that a separate lamp must be added in order to warn drivers and / or pedes...
