Kind Code:
A1
Abstract:
Provided are a method and a system for testing field of view. Said method comprises: placing an image acquisition apparatus (3) at a provided viewpoint position of an image output device, and placing a grid line apparatus (4) at a set distance in front of the image acquisition apparatus (3), a grid pattern (7) being provided on one side of the grid line apparatus (4) facing the image acquisition apparatus (3); controlling the image output device to output a test pattern (6); moving the grid line apparatus (4), keeping the distance between the grid line apparatus (4) and the image acquisition apparatus (3) unchanged, and making the center line of the grid pattern (7) coincide with the center line of the test pattern (6) outputted by the image output device; using the image acquisition device (3) to capture an image of the grid pattern (7) and the test pattern (6); and determining, according to the relationship between the test pattern and the grid pattern in the captured image, the field of view of the image output device.
