PROJECTION TYPE IMAGE DISPLAY DEVICE

摘要

A projection type image display device includes a processor having a measuring part for performing a three-dimensional measurement of an A-pillar and a projection range controller for controlling a projection range of an image light, which is matched to an A-pillar surface based on a result of the three-dimensional measurement. Thus, the projection of an image onto the A-pillar surface by the projection type image display device is easily performed regardless of whether the A-pillar surface is a two-dimensional flat surface or a three-dimensional surface. The projection type image display device also directs a retro-reflective component in a reflected image light away from a driver's seat based on a positioning of an image projection device. Speckled uneven image brightness on an image display surface is thereby prevented.

主权项

1. A projection type image display device comprising:
an image projection device projecting a measurement light onto a target object to provide a three-dimensional measurement of the target object and projecting an image light onto an object surface of the target object to display an image onto the object surface; a measuring part performing the three-dimensional measurement of the target object by using the measurement light; and a projection range controller controlling a projection range of the image light to match the projection range with the object surface based on a result of the three-dimensional measurement.
