“…Because time (t) is interval of two adjacent frames, which is considered as a constant. So equation ( 4) is derived, the argument of vector ( r ) is calculated using iterative calculation method by equation (5). And the argument of vector (θ ) is obtained by equation ( 6).…”

Occlusion is a difficult problem to be solved in the process of target tracking. In order to solve the problem of occlusion, a new tracking method combined with trajectory prediction and multi-block matching is presented and studied,and a mathematical model of trajectory prediction of moving target is established in polar coordinates and verified through some experiments. The experimental results show that the new tracking method can be better to trace and forecast the moving target under occlusion.

Based on the instability problem of target tracking performance in the optical tracking imaging system of field operations, this article researches the target tracking capture rate. The target tracking platform is established with target imaging radiation characteristics and target movement features and target optical properties are researched with photometry knowledge. According to target detection range, target size, environmental illumination and area array CCD imaging characteristics, the calculation model of target tracking capture rate is deduced and the factors that affecting the target capture rate are analyzed. By calculation and experimental analysis, the target capture rate decreases when the detection range increases and the target capture rate increases when the target size is larger. The target gray value is relatively stable when the weather is sunny and target images captured by CCD are given when the target size is 5.56× 45 normalmnormalm. The optical imaging system can work day and night and the target capture rate can get 95% with the laser strobe auxiliary illumination technology. © 2016 Wiley Periodicals, Inc.

In order to meet the requirements of high-precision target displacement measurement, this paper proposed a measurement method based on monocular vision measurement system by which the advantages of simple structure, convenient debugging, easy to install and calibrate is recognized. This method first uses the bundle adjustment algorithm with conditional constraints to optimize the solution results of the orthogonal iterative algorithm, then calculates the relative poses of the optimization results, finally establishes an error correction model to perform secondary optimization on the relative poses. The experimental results show that the method proposed in this paper can reduce more than 54% average error of displacement measurement results, and the error between the final displacement measurement results and the actual displacement values is controlled at 0.4mm level, which proves that the method has good practical value.
