Abstract

The invention discloses a projection system and a correction method of a projection image. The projection system comprises a projection target and a projection device. The projection target comprises a reference pattern and receives an image beam to match the image beam to display the projection image. The projection device projects the image beam to the projection target. An image capture device captures a capture image having the projection image and outputs the capture image to the projection device. The projection device adjusts the projection parameters of the image beam according to the projection image in the capture image. Based on the adjusted projection parameters, the image beam displays the reference pattern corresponding to the corrected projection image. By adoption of the correction method of the projection image and the projection system, the projection image of the projection system can be located on a correct position corresponding to the projection target, and thus the automatic correction of the projection image is realized.

Description

technical field [0001] The present invention relates to a projection system, and in particular to a projection system and a method for correcting projection images. Background technique [0002] At present, optical axis correction is a very important part of projection system assembly, especially for embedded projection modules, the relative position of the projector and the projection surface must be adjusted during assembly, so that the projector The projected picture can be presented at the correct position on the projection surface. However, the process of optical axis calibration is time-consuming and labor-intensive, and professionals must use adjustment tools to adjust the projection systems one by one. In addition, if the projection system needs to be assembled separately after leaving the factory, the projection system must be fine-tuned after leaving the factory. If the projector is delivered to the customer in the form of modules, the projection system must be f...
