“…In the development of biomimetic compound-eye imaging system based on camera arraya, a number of large field of view and high resolution biomimetic compound-eye imaging systems have been developed. In terms of the development of scientific detection imaging equipment, a large field of view ultra-high pixel imaging system (aware-2) has been developed by the Duke University in the United States [ 9 ]. The system is composed of a concentric spherical lens and 98 micro camera arrays.…”

With the rapid development of the virtual reality industry, one of the bottlenecks is the scarcity of video resources. How to capture high-definition panoramic video with depth information and real-time stereo display has become a key technical problem to be solved. In this paper, the optical optimization design scheme of panoramic imaging based on binocular stereo vision is proposed. Combined with the real-time processing algorithm of multi detector mosaic panoramic stereo imaging image, a panoramic stereo real-time imaging system is developed. Firstly, the optical optimization design scheme of panoramic imaging based on binocular stereo vision is proposed, and the space coordinate calibration platform of ultra-high precision panoramic camera based on theodolite angle compensation function is constructed. The projection matrix of adjacent cameras is obtained by solving the imaging principle of binocular stereo vision. Then, a real-time registration algorithm of multi-detector mosaic image and Lucas-Kanade optical flow method based on image segmentation are proposed to realize stereo matching and depth information estimation of panoramic imaging, and the estimation results are analyzed effectively. Experimental results show that the stereo matching time of panoramic imaging is 30 ms, the registration accuracy is 0.1 pixel, the edge information of depth map is clearer, and it can meet the imaging requirements of different lighting conditions.

“…An inexpensive and simple focusing solution for MMS lens architectures is highly desirable. Several previous trials relying on piezoelectric motor have been successful but too expensive for mass production [5,19,20]. MFM based on VCM actuators provide a promising chance to resolve this challenge.…”

We explore integrated microcamera focus systems for array cameras. Array cameras enable wide field of view 90° to 360° high resolution (10–100 μrad) imaging with small exit apertures (≈10 mm). Small exit apertures enable compact focus mechanisms with fast actuators. We show that a common mechanism supports ≈f/2.5 camera modules with focal lengths ranging from 25 to 60 mm. Designs for each focal length include a fixed objective lens group and an adjustable back focus group. Increasing the focal power of the front focal group enables the travel range to accommodate long focal length systems. We present design examples for both discrete and multiscale array camera systems.

We explore integrated microcamera focus systems for array cameras. We propose a new model for system camera integration relying on fast action focus mechanisms with < 10mm aperture. Rather than reducing resolution or expanding aperture size, such systems can be used in arrays to enable digital zoom. We show that a common mechanism supports camera modules with focal lengths ranging from 25 to 60 mm. Designs for each focal length include a fixed objective lens group and an adjustable back focus group. Increasing the focal power of the front focal group enables the travel range of available microcamera modules to accommodate long focal length systems. We present design examples both discrete and multiscale array camera systems.
