Abstract

The invention is suitable for the field of optics, and provides a method and device for eliminating stray light under a screen, an under-screen system and a storage medium. The method for eliminating stray light under the screen comprises the following steps of acquiring an echo signal received by a signal receiving end positioned on the inner side of the display screen, wherein the echo signal is an optical signal received by a signal receiving end after a signal transmitting end located on the inner side of the display screen transmits a first optical signal to a target area on the outer side of the display screen, obtaining a stray light signal received by the signal receiving end after the first light signal is reflected and / or scattered by the display screen, and based on the echo signal and the stray light signal, calculating a target light signal of the target area reflecting the first light signal. According to the method provided by the embodiment of the invention, stray light under the screen can be eliminated, so that the accuracy of the depth measurement value is improved.

Description

technical field [0001] The present application belongs to the field of optics and image processing, and in particular relates to a method, a device, an under-screen system and a storage medium for eliminating stray light under a screen. Background technique [0002] At present, in order to improve the integrity of the screen and the appearance of the product, technicians are constantly trying to place the 2D camera and the 3D camera under the display screen. However, when 3D technologies such as indirect time-of-flight (Indirect TOF, iTOF), direct time-of-flight (Direct TOF, dTOF), and structured light are applied to off-screen imaging, the signal receiving end located inside the display often receives Stray light signals, causing abnormal depth measurements. [0003] Therefore, a method for eliminating stray light under the screen is needed to improve the accuracy of depth information in applications such as 3D technology.
