VR Lens stray light noise detection and calculation method

Abstract

The invention provides a VR Lens stray light noise detection and calculation method. The method comprises the following steps: S1, acquiring an image; S2, processing the image, and capturing stray light noise; and S3, partitioning the area where the stray light noise is located, calculating the area of each partition, and determining the numerical value of the stray light noise according to the area. In the prior art, the VR Lens detection mainly depends on a visual inspection mode, glasses need to be close to a product during detection, each visual inspection only focuses on the detection of the Lens on one side of the VR product, the efficiency is low, an operator is easily tired, and the vision may be influenced for a long time; the sensitivity and quality control ability of personnel are different, a high detection rate is difficult to guarantee, Lens cannot be partitioned, the bad layer degree cannot be accurately judged, and the detection process cannot be traced. According to the invention, intelligent detection of VR Lens is realized through effective analysis of VR images and capture of stray light noise.

Description

technical field [0001] The invention relates to automatic optical detection, and relates to a detection and calculation method for stray light noise of a VR Lens. Background technique [0002] At present, the mainstream of VR Lens is to use Fresnel lenses. Due to the abnormal thread structure or sawtooth structure on the surface of Fresnel lenses, stray light / noise occurs when the VR display screen reaches the human eye through the VR Lens. There is no device on the market corresponding to this type of device used in the VR production line. In the production process of VR products, the inspection of VR Lens mainly relies on visual inspection. The glasses must be very close to the product during inspection, and each visual inspection can only focus on inspection. The Lens on one side of the VR product is inefficient and easily fatigues the operator, which may affect vision for a long time. The acuity and quality control ability of personnel are different, so it is difficult ...

[0002] At present, the mainstream of VR Lens is to use Fresnel lenses. Due to the abnormal thread structure or sawtooth structure on the surface of Fresnel lenses, stray light / noise occurs when the VR display screen reaches the human eye through the VR Lens. There is no device on the market corresponding to this type of device used in the VR production line. In the production process of VR products, the inspection of VR Lens mainly relies on visual inspection. The glasses must be very close to the product during inspection, and each visual inspection can only focus on inspection. The Lens on one side of the VR product is inefficient and easily fatigues the operator, which may affect vision for a long time

The sensitivity and quality control ability of personnel are different, so it is difficult to ensure a high detection rate, and it is impossible to partition the Lens and accurately determine the level of defectiveness, and the detection process is not traceable
