Title:
MOVING INTELLIGENT PROJECTION SYSTEM AND METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/171041
Kind Code:
A1
Abstract:
A moving intelligent projection display system and a method, the projection display system comprising: a projection unit (10), an environment identification unit (20), a target direction identification unit (30), a first direction control unit (40) and a central processing unit (50). The environment identification unit (20) identifies a complete projection screen image of the projection unit (10) as well as changes in environment. The target direction identification unit (30) traces and determines an intended projection direction of a user according to directionality information of the user. The first direction control unit (40) simultaneously changes the projection direction of the projection unit (10) and the acquisition direction of the environment identification unit (20). The central processing unit (50) comprises a target direction processing unit (51) and an image correction unit (52). The target direction processing unit (51) calculates a rotation angle of the first direction control unit (40) according to the directionality information of the user. The image correction unit (52) analyzes and compares the projection screen image and information of the changes in the environment which are acquired by the environment identification unit (20), and performs real-time projection image correction. The moving intelligent projection display system may trace an intended projection direction of a user in real time by means of the target direction identification unit (30), change the direction of a projection lens in real time and perform projection screen correction, thus achieving high-quality intelligent projection display.
