Document Type and Number:
WIPO Patent Application WO/2019/127319
Kind Code:
A1
Abstract:
A distortion measurement method and system for a head-mounted display device. The distortion measurement method comprises: using a display lens of a head-mounted display device to project an image undergoing detection so as to generate a projected image; using a camera to capture the projected image; and performing, according to the projected image, calculation to obtain a distortion associated with the head-mounted display device. In the invention, a projected image of an image undergoing detection of a head-mounted display device is captured by means of a camera rather than human eyes, and then the projected image is analyzed to obtain a quantized distortion value associated with the head-mounted display device.
