Document Type and Number:
WIPO Patent Application WO/2019/218801
Kind Code:
A1
Abstract:
The present invention relates to a projection device and system, and a projection method. The projection device comprises a region selection portion (101), an image calibration portion (102), and a projection portion (103). The image calibration portion (102) is separately connected to the region selection portion (101) and the projection portion (103). The region selection portion (101) is configured to select at least one projection region, and send position information of the projection region to the image calibration portion (102); the image calibration portion (102) is configured to obtain a relative position relationship between the projection region and the projection portion (103), and calibrate, according to the relative position relationship, an image to be displayed; the projection portion (103) is configured to project the calibrated image to be displayed to the projection region. In the present invention, the projection device can automatically adjust the position of the projection region in a projection manner according to the mounting position, a large window is ensured, and a viewing effect is improved. In addition, a caliber of a reflective mirror is not required to be increased in the projection device, the volume of the projection device is not increased, and limitations on the mounting position are few.
