Geometric figure projection imaging automatic correction device and correction method thereof

Abstract

The invention provides a geometric figure projection imaging automatic correction device comprising a projector, a projection curtain, a camera and an image processor. The image processor is electrically connected with the projector and the camera respectively. The camera and the projection lens of the projector are installed in a mutually adjacent way. The image processor projects original projection content to the projection curtain via the projector. The camera photographs the projection content on the projection curtain and transmits the projection content to the image processor. The projection content photographed by the camera is compared with the original projection content by the image processor and then correction is performed. The invention also provides a correction method of the geometric figure projection imaging automatic correction device. The original projection content and frames captured by the camera are compared by the image processor, and whether the frames captured by the camera are deviated from the original projection content is judged. The beneficial effects of the geometric figure projection imaging automatic correction device and the correction method thereof are that a problem that projection figures are diverse and are not easy to correct can be completely overcome, and an effect that the geometric figures can be automatically judged and corrected can be achieved.

Description

technical field [0001] The invention relates to the field of image correction, in particular to an automatic correction device for geometric figure projection imaging and a correction method thereof. Background technique [0002] The current trapezoidal correction device of the projector includes an angle sensor, an angle processing unit, and an image correction unit. The angle sensor is arranged on the optical system module inside the projector, and is used to detect the angle of the optical system in the projector. The angle processing unit uses The keystone correction value is obtained according to the angle of the optical system module, and the keystone correction value is sent to the image correction unit of the projector, and the image correction unit is used for performing keystone correction on the input image according to the keystone correction value. For the correction of geometric figures, it is mainly aimed at the main body of the projector, which is equipped wi...
