Multi-lens image photographing module

Abstract

The invention discloses a multi-lens image photographing module. The module comprises a mounting shell base, more than two lenses, positioning plates matching the lenses, flat cable soft plates matching the lenses, a PCB, an image synthesis IC processor and a bottom plate mounted under the mounting shell base in a matching manner; the mounting shell base is provided with more than one groups of symmetrical mounting inclined planes, and the top of the mounting shell base can be provided with a mounting plane for combination of separate installation of the lenses; an inclined angle between the two mounting inclined planes of the mounting shell base can be calculated through a best configuration angle formula, so best configuration angles of lenses capable of adapting to various different angle specifications can be set; and a distortionless synthetic image greater than or equal to 180 degrees is obtained through operation edit of the image synthesis IC processor. Each of the various lenses can be corrected separately to obtain a parameter, and the other lenses can be rapidly and simultaneously corrected by using the same parameter, so the need of mass production can be met.

Description

technical field [0001] The invention relates to a multi-lens image photography module, which is suitable for driving recorders, monitors or other photographic equipment that requires lenses, and can provide composite images greater than or equal to 180° without distortion. Background technique [0002] Known video camera modules with multiple lenses usually face the problem of lens correction difficulties in mass production. For example, the new Taiwan China No. M435625 is designed for a dual-lens video camera module, which must perform angle correction on both lenses at the same time , so the calibration work is very difficult, not only not suitable for mass production, but also has a high error rate of calibration, which cannot improve the product yield.

Problems solved by technology

[0002] Known video camera modules with multiple lenses usually face the problem of lens correction difficulties in mass production. For example, the new Taiwan China No. M435625 is designed for a dual-lens video camera module, which must perform angle correction on both lenses at the same time , so the calibration work is very difficult, not only not suitable for mass production, but also has a high error rate of calibration, which cannot improve the product yield

[0003] Furthermore, regarding the acquisition of images, it is usually difficult to obtain images greater than or equal to 180° except for fisheye lenses. It presents an actual image greater than or equal to 180°. Therefore, at present, an image camera module with multiple lenses is often used for improvement. However, there is a manufacturing problem of difficult lens correction, which does not meet the needs of mass production.

[0004] In addition, the known lenses have different specifications due to their imaging angles. For example, there may be lenses with an imaging angle of 60° earlier, or other lenses with an imaging angle lower than 90°. If you want to obtain a true composite image of 180° , it is necessary to use three lenses. Therefore, with regard to the angle configuration of the video camera module of multiple lenses, if the optimal angle configuration is to be achieved, due to the large number of known lens specifications, the imaging angle is not fixed and uniform, so it is difficult to structurally Adapt to obtain an optimal positioning angle
