Dual-lens positioning detection system and dual-lens positioning detection method

Abstract

The invention discloses a dual-lens positioning detection system and a double-lens positioning detection method. The detection system comprises a first collimator and a display device. The first collimator is internally provided with a first transmission test target. The first collimator is perpendicular to the optical axis of a dual-lens and is aligned at the middle position of two lenses of the dual-lens. In detection, the two lenses collect first transmission test target images in the first collimator and send the images to the display device. The display device receives the images from the two lenses and carries out parallel displaying of the images from the two lenses at the same time. The first collimator is arranged to be aligned at the middle position of the two lenses of the dual-lens and perpendicular to the optical axis of the dual-lens, the two lenses are used to collect the first transmission test target images in the first collimator and send the images to the display device for parallel displaying, through observing whether the two images are aligned to each other, whether the two lenses are in a same horizontal position is judged, and the detection of the optical axis dislocation of the dual-lens is realized.

Description

technical field [0001] The invention relates to the technical field of panoramic shooting, in particular to a dual-lens positioning detection system and a dual-lens positioning detection method. Background technique [0002] Panoramic technology is a technology that shows the whole picture of the scene by shooting from all angles. It is an important means of generating virtual reality technology film and television materials. At present, the panoramic cameras used to shoot panoramic pictures or videos on the market are mostly composed of double lenses with 720 degrees. The product principle is to use more than two fisheye lenses with large viewing angles (horizontal and vertical viewing angles of more than 180 degrees), and set them in relatively opposite directions (such as figure 1 shown), and then use the software to stitch the pictures and correct the lens distortion to complete the 720-degree panoramic viewing angle. [0003] However, in the existing dual-lens panorami...

Problems solved by technology

[0003] However, in the existing dual-lens panoramic camera, the dual-lens 1 is combined with the substrate 2 in a back-to-back manner during the assembly process, and the positioning methods include fixing with screws or glue. There is a problem that the two lenses are not on the same optical axis, and there is no precise way to measure and detect in the existing assembly process, resulting in the problem that defective products cannot be detected, which affects the panoramic shooting effect
