Measuring system and method of imaging precision, test host

Abstract

The embodiment of the invention relates to the testing technical field, and discloses an imaging precision measuring system and method, and a testing main machine; the imaging precision measuring system comprises a test camera and the testing main machine; the testing main machine respectively communicates with the test camera and a to-be-tested device; the test camera is located in an observationposition of the to-be-tested device; the testing main machine is used for controlling the to-be-tested device to display a preset test pattern, and using the test camera to capture the test pattern;the testing main machine is also used for selecting at least four test points on the test pattern, and obtaining two dimension coordinates of each test point on the test pattern captured by the teat camera; the testing main machine is also used for obtaining theoretical three dimensional coordinates of each test point according to the two dimension coordinates of each test point, and obtaining theimaging precision of the to-be-tested device according to the two dimension coordinates and theoretical three dimensional coordinates of each test point. The measuring system and method can quantitatively measure the imaging precision of the to-be-tested device, are more objective in test results, and fast in a test speed.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of testing, and in particular to a measurement system and method for imaging precision, and a testing host. Background technique [0002] Virtual reality (Virtual Reality, VR) and augmented reality (Augmented Reality, AR), as the most popular visual interaction methods, have developed rapidly in recent years. In the existing VR and AR technologies, two images with visual difference are mainly projected on two screens to display a virtual 3D scene in front of people's eyes. [0003] For existing VR and AR devices, the design and assembly of the optical system directly affects the imaging quality of the entire device. If the imaging is off-centered or skewed, it will lead to ghosting and focus blur in the final displayed 3D image. [0004] The inventors have found that there are at least the following problems in the prior art: for the existing VR and AR equipment, in the production ...

Problems solved by technology

[0003] For existing VR and AR devices, the design and assembly of the optical system directly affects the imaging quality of the entire device. If the imaging is off-center or skewed, it will lead to ghosting and focus blur in the final displayed 3D image.

[0004] The inventors have found that there are at least the following problems in the prior art: for the existing VR and AR equipment, in the production process, if the imaging quality of the VR and AR equipment is to be tested, the testers can only observe some test scenes with human eyes. Make judgments, the test results are subjective; and the test efficiency is low
