    • 摘要: 采用主动式红外热成像检测材料缺陷,在控制外界环境影响因素的前提下,实验研究并分析了热激励时间和探测距离两个检测因素的影响。同步采集得到最佳参数下玻璃钢平底孔试块的红外热图像序列。主动式红外无损检测通常获得包含数百帧图的红外序列,为了获取反映整个图像序列的主要信息,采用了主成分分析算法(principal component analysis,PCA)对图像序列进行处理。首次探究了融合区间对PCA算法处理结果的影响,提出了可依据温差峰值下降的百分数来选择融合区间,并对处理结果进行了主客观的对比评价分析。研究结果表明当温差峰值下降到80%时,选择大于该值对应的序列图像帧数作为融合区间时,PCA处理的效果最佳。最后探讨了PCA处理中减少红外镜头反光等影响因素的策略。

    • 摘要: 在涡流脉冲热像技术中,红外图像序列受到设备精度、环境干扰等因素的影响,其质量易发生退化,进而影响后续缺陷的特征提取和识别,因此,有必要对图像序列进行降噪预处理.为得到质量可靠的红外图像序列,以涡流脉冲激励下的红外图像序列为研究对象,分析了其噪声来源和类型;通过空间域和时间域2种途径对图像序列进行降噪处理.结果表明:时间域处理效果优于空间域,降低噪声的同时保留了缺陷区域随时间变化的热响应特征,更适合处理红外图像序列.研究成果为缺陷的特征提取和识别奠定了理论基础.%In eddy current pulsed thermography, the thermal image sequence is affected by equipment accuracy, environmental interference and other factors, which leads to the degradation of its quality and then affects the subsequent defect feature extraction and recognition.Therefore, the preprocessing of thermal image sequences is required.In order to obtain a reliable thermal image sequence, the infrared image sequence under the eddy current impulse is taken as the object of study, and its noise source and type are analyzed.Then the image sequence is processed by spatial domain and time domain.The results show that the time domain processing is superior to the spatial domain, which reduces the noise while preserving the thermal response characteristics of the defective region over time, and is more suitable for processing the thermal image sequence.The research results provide the basis for the feature extraction and recognition of defects.

    • 摘要: In view of the problems of tracking instability and non real‐time and highly nonlinear measurement model for the detection and tracking of multiple Infrared ( IR ) dim targets under the complicated background , a fast detection and tracking algorithm based on multi‐Bernoulli filter is presented . Firstly , the improved Robinson Guard filter suppresses the background clutter in order to avoid the suppression of the target in the strong background image . Then , the square‐root cubature Kalman filter (SCK) performs the multi‐Bernoulli track‐before‐detect ( MB‐TBD) . It can perform real‐time tracking in the highly nonlinear model . The numerical instability caused by a negative definite covariance matrix is avoided . The experiments with some real IR background images show that the improved Robinson Guard algorithm can suppress the background clutter effectively and preserve the dim target information . It is also shown that SCK‐MB‐TBD can estimate the number and states of targets accurately and stably so as to complete target detection and tracking .%针对复杂背景下多个弱目标检测与跟踪中存在的跟踪不稳定、非实时及量测模型高度非线性问题,提出一种基于多伯努利滤波的快速检测与跟踪算法。首先,采用改进的Robinson Guard算法抑制背景杂波,避免强起伏背景图像中目标被抑制的问题;其次,采用平方根容积卡尔曼滤波实现多伯努利检测前跟踪,在保证实时跟踪的同时,解决了滤波的高度非线性,避免了协方差矩阵负定造成的数值不稳定。实测红外背景图像实验表明,改进的Robinson Guard算法能够有效抑制背景杂波、保留弱目标信息,平方根容积卡尔曼多伯努利检测前跟踪能更准、更稳定地估计目标数目和状态,实现目标的实时检测与跟踪。

    • 摘要: Considering the shortage of conventional single-image-SVD-based infrared dim and small target detection method, a new sequential-image-SVD-based method is proposed in this paper. Firstly, an image matrix is constructed upon sequential images and then decomposed by the SVD algorithm, and consequently the corresponding singular values and singular vectors are achieved. Secondly, new sequential feature images are reconstructed by using processed singular values and singular vectors. Thirdly, the selected feature images from sequential feature images are further processed to enhance the small targets and suppress the clutter background. Fourthly, the small targets are obtained by segmenting feature images. Finally, the detection task of small target detection is completed by refining the inter-frame and intra-frame target locations. Experimental results show that the proposed algorithm is robust and with real-time efficiency.%鉴于传统的基于单幅图像奇异值分解红外弱小目标检测算法的不足,提出了一种新的基于图像序列奇异值分解的红外弱小目标检测算法。首先,利用图像序列构造图像矩阵并进行奇异值分解,得到对应的特征值与特征向量;其次,利用处理后的特征值和特征向量重构图像序列,得到新的特征图像序列;再次,在特征图像序列中选取合适的特征图像进行处理从而增强目标并抑制背景;然后,对新特征图像进行阈值分割,得到要检测的弱小目标;最后,对序列中的每幅图像分别进行帧间位置修正与帧内位置修正,以达到检测红外弱小目标的目的。实验结果表明该算法具有很好的鲁棒性与实时性。

    • 摘要: Background radiation noise interference is a difficult technical problem for dim signal detection. A dim target detection algorithm was proposed which can significantly improve signal-to-noise ratio (SNR) to achieve uniformly motion dim target detection successfully. Firstly, a coordinate space and a velocity space were established. Then the original image sequence was stacked along different velocity vectors to acquire a new image sequence with SNR improved and the new image sequence forms an image space. Secondly, quasi-target points in the image space were detected by constant false-alarm ratio (CFAR) judging. Finally, velocity vectors and coordinate vectors of quasi-target points were mapped to the velocity space and the coordinate space respectively. As a result, two local peaks from the spaces will confirm true target points.Experiments of real images from actual IR imaging system show that proposed algorithm can improve SNR approximately up to √N times of original image SNR, and the proposed algorithm is demonstrably superior to compared algorithms on detection probability and false alarm probability.%背景辐射噪声是弱信号检测面临的难点问题.提出了一种显著提升信噪比实现匀速运动弱目标的有效检测算法.建立目标坐标空间和速度空间,以不同速度矢量控制图像叠加,形成提升了信噪比的新的图像序列并构成图像空间;利用恒虚警判决法在图像空间中检测候选目标点;根据候选目标点所对应的坐标向量和速度向量分别映射到坐标空间和速度空间,由两个空间中出现的峰值判定目标点.实际红外成像系统实拍实验表明,算法能将信噪比提升至接近原图的√N 倍,目标检测概率和虚警概率都明显优于所对比的弱目标检测算法.

    • 摘要: 以动态背景中红外运动目标为研究对象,针对二维初级运动检测器在时域上对运动敏感而引起目标运动矢量受背景变化干扰的问题,提出一种结合时域中生物视觉二维初级运动检测器和空域中区域生长方法的运动检测方法。该方法利用时域中二维初级运动检测器检测出运动矢量并将幅值最大的运动矢量作为区域生长的种子点,利用空域中运动目标具有较高红外辐射的图像特性,通过区域生长法,将热辐射特性强于背景的目标分割出来。仿真实验结果表明:该方法在去除背景干扰的同时提取出动态背景中的运动目标,与其他方法相比具有较高的信杂比。%An infrared moving object detection method which combines Reichardt-type two dimensions Elementary Motion Detectors inspired by biological vision and region growing method was proposed to solve the two dimensions EMDs′ sensitive problem in dynamic scenes. EMDs detected the most intensive motion vector signal in temporal domain which was then used as the seeds of the region growing. Region growing method was applied to make a segmentation of the target by its infrared radiation characteristic much different from background in spatial domain. The simulation illustrates that, combing the EMDs in temporal domain with the region growing method in spatial domain achieves much better detection performance in infrared frames than the original Reichardt′s model. Compared with other methods, the proposed method could achieve a higher SCR.

The target initial position in the original image frame is obtained using the correlation matching algorithm. According to the recognition properties of the target, the decision functions are established. The classification of the connected regions in the current frame is determined by calculating Bayesian probability. The pattern vector is updated after the new target is located in the current frame for the target recognition in the next frame,and the purpose of moving target recognition is achieved. Experimental results show that: according to the recognized properties and probability calculation, the method can recognize the moving target fast and effectively with low computational complexity, and also the algorithm used is suitable for embedded system complementation and has strong robusticity.
