The wide-area imaging becomes difficult due to the small overlapping area of multi-camera images
large parallax
and complex and changeable feature information in practical application scenarios when a multi-camera detection system is used to provide environmental perception for military vehicles such as tanks and armored vehicles.A wide-area real-time imaging algorithm based on ChArUco board calibration is proposed
and a wide-area visual enhancement system for military vehicles is designed for drivers to perform real-time imaging of the external environment in a closed compartment with limited vision.This algorithm takes advantage of the characteristic that the ChArUco board can still be accurately calibrated under occlusion conditions to achieve the accurate calibration of a small-overlapping multi-camera system.Projection transformation is carried out through calibration parameters to avoid the interference of image feature information and effectively deal with complex feature scenarios.At the same time
the parallax in the overlapping area is eliminated by the fusion of optical flow relationships
and a wide-area real-time imaging is achieved by using the projection look-up table and parallel acceleration optimization method.This algorithm is deployed on a mobile computing platform to form a complete wide-area visual enhancement system.The experimental results show that this system and algorithm can meet the wide-area real-time imaging requirements of various scenarios and improve the visual perception ability of military vehicles in complex environments.

(in Chinese) DOI: 10.12382/bgxb.2021.0393 http://doi.org/10.12382/bgxb.2021.0393 To resolve the problems of high mass and high volume of image data generated by the multi-channel camera array in a bionic compound eye, a large FOV bionic compound eye imaging system and an image fast mosaic recognition algorithm based on multi-channel single detector is proposed. By using optical path refraction and normalization, multi view sub eye image plane coplanar and single photodetector partition imaging are realized. Based on the imaging characteristics of catadioptric eyes, an image mosaic algorithm based on the structural similarity at the feature map level is proposed. Fast reconstruction and target recognition of global images with a large field of view (FOV) in a compact space are realized by using a convolution neural network for target recognition. The proposed compound eye system has an effective optical FOV of 138°×75°, an optical dimension is 29.78 mm×19.74 mm×6.86 mm, and a global image mosaic speed is 0.011 s. The compact catadioptric compound eye has the advantages of small volume, large FOV, and low computational cost. It can provide wide area vision and fast image mosaic recognition capabilities for small unmanned equipment and low speed projectiles with limited load and computational power.

Nowadays parallax image registration has gradually become a research focus in image mosaic technology. The difficulty and general flow of parallax image registration are introduced based on the principle of parallax formation. And the feature-based parallax image registration technology is mainly introduced. The research results of parallax image registration in recent years are summarized and expanded from the image registration based on multi-plane alignment, the image registration based on mesh deformation and the seam-driven image registration. Through summarizing and comparing the algorithm ideas, characteristics and limitations of various typical parallax image registration algorithms, a systematic overview of the research status in this field is provided. Furthermore, the future research directions of parallax image registration are also prospected.</p>

DOI: 10.12263/DZXB.20200664 http://doi.org/10.12263/DZXB.20200664 针对视差图像拼接之后存在对齐不准和扭曲的问题,提出一种基于局部投影的视差图像拼接的平滑优化方法.将输入图像进行特征点检测,通过局部保留结构进行图像匹配并计算投影矩阵,利用重合边界投影模型与投影矩阵进行归一化距离判定,距离小于阈值则保留,大于阈值则舍弃并继续矩阵计算.在图像非重合部分,利用图像的变形函数得到最小弯曲能量函数,使非重合区域向全局变换上过渡.实验结果表明:所提算法提高了图像匹配精度,对图像的扭曲具有优化作用,增强了图像的整体性并获得了更好的视觉体验.

(in Chinese) DOI: 10.12263/DZXB.20200664 http://doi.org/10.12263/DZXB.20200664 Aiming at the problems of misalignment and distortion after parallax image stitching, a smooth optimization method for parallax image stitching based on local projection is proposed. The input image is performed feature point detection, matched by locality preserving structure, and calculated the projection matrix. The normalized distance is determined by the projection model of the coincident area and the projection matrix. If it is less than the threshold, it will be retained, otherwise it will be discarded and continue matrix calculation. In the non-coincident part of the image, the minimum bending energy function is obtained by calculating the deformation function of the image, so that the non-coincident region transits to the global transformation. The experimental results show that the proposed algorithm can not only improve the matching accuracy of the image, but also optimize the distortion of the image, enhance the integrity of the image and obtain a better visual experience.
