Problems solved by technology

[0004] However, in the general dual-camera stereo vision technology, there is no effective solution to horizontal and vertical stripes, repetitive lines, shading, reflections, and depth noise. Most of them can only obtain images from the difference between the left and right color images. However, its effect is very limited and it is easy to cause troubles and flaws in back-end applications

Embodiment Construction

[0028] Generally speaking, a traditional camera used to produce stereoscopic images is composed of dual lenses with the same specifications. The distance between the two lenses is about 7.7 cm, so as to simulate the actual distance between human eyes. And other parameters are controlled by the processor of the camera, and through the trigger of the shutter cable, images of the same area but with different perspectives can be taken, which is used to simulate the images of the left and right eyes of human beings. However, this type of camera can only obtain image depth information from the difference between the left and right color images for objects with horizontal and vertical stripes, repetitive lines, shading, reflections, and depth noise. However, the effect is very limited and it is easy to cause back-end Application troubles and flaws. The present invention proposes an image acquisition device with at least three lens modules, which combines images obtained by combining ...

Abstract

The present invention provides an image acquisition device comprising at least three lens modules, a storage unit and a processing unit, wherein the storage unit is coupled to the lens modules, and the processing unit is coupled to the storage unit and the lens modules. Each of the lens modules is used for obtaining the image of a shot object respectively. The storage unit is used for storing the images obtained by the lens modules. The processing unit is used for obtaining the complete depth information of the shot object according to multiple image combinations formed by every two images. According to the image acquisition device provided by the invention, the problem of inaccurate estimation of depth information caused by the factors of cross stripes, repetitive lines, shading, reflective and depth noise of the depth information can be solved.

Description

technical field [0001] The present invention relates to an image acquisition device, and in particular to an image acquisition device with multiple lens modules. Background technique [0002] With the development of technology, various smart electronic devices, such as tablet computers, personal digital assistants, and smart phones, have become indispensable tools for modern people. Among them, the camera lenses of high-end intelligent electronic devices are already comparable to traditional consumer cameras, and can even replace them. A few high-end models also have the pixel and image quality close to digital SLR or the function of shooting three-dimensional images. [0003] For the aforementioned electronic device equipped with dual lenses, the distance between the two lenses is set to be approximately equal to the average distance between human eyes, thereby simulating the left and right eyes of human beings to capture 3D images. When human eyes look at the same object ...
