Embodiment Construction

[0042] The core idea of ​​the present invention is: set the first collimator so that it is aligned with the middle position of the two lenses of the double lens, perpendicular to the optical axis of the double lens, and use the two lenses to collect the first transmitted light in the first collimator respectively. The image of the test target is sent to the display device to be displayed side by side. By observing whether the two images are aligned, it is judged whether the two lenses are at the same horizontal position, and the detection of the misalignment of the optical axis of the double lens is realized.

[0043] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

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...
