Abstract

A method for calibrating the spatial position of a dual-camera module, including the first module and the second module respectively photographing the same target to obtain a first image and a second image, wherein the target has a plurality of marks arranged in an array spaced apart from each other point; process the first image and the second image to obtain a clear black and white test image; respectively adaptively locate the marker points in the first image and the second image; adaptively match the first image respectively An image and the marker point in the second image; marking the first module and the second module; and computing to obtain the relative spatial position of the dual-camera module. The invention can reduce the influence of interference noise and ambient brightness on the result, has high stability, flexibility and precision, and is suitable for batch use in production.

Description

technical field [0001] The invention relates to a method for calibrating the spatial position of a dual-camera module. The relative spatial position of the dual-camera module can be obtained by adopting an adaptive positioning and matching method. Background technique [0002] With the rapid development of science and technology, various technology-related products have emerged accordingly, especially smart mobile devices, such as mobile phones, tablet computers, PDAs, etc. The most common situation is that each person holds more than one smart phone, and the camera included in the smart phone is a main function of the phone. The quality of the camera It even becomes one of the conditions for people to purchase the above-mentioned smart phones. Because of the change of the times, people's habits are also gradually different. Nowadays, most people are more accustomed to using the camera of the mobile phone to replace the general traditional camera to record life and directly...
