针对静态感知系统的坐标系改进设计

由于四个菲涅尔透镜和四个热释电传感器组成的四元十字阵列静态感知系统探测视场角度大,相邻感知区域有重叠,导致传统的感知系统坐标系的探测精度降低。为了提高探测目标的可靠性,提出一种改进的二维坐标系。该坐标系根据相邻感知区域的重叠区,重新建立十字坐标系统。文中建立了新坐标系的理论模型,经过实验验证,该改进坐标系设计切实可行,使感知系统探测目标精度有所提高,具有一定的实际应用价值。

Improvement of the coordinate system for static perception system

Four element cross array static perceptual system,which is consisted of four Fresnel lens and four pyroelectric sensors,has detection viewing field with a large angle and adjacent overlapping sensing area,which leads to low detecting precision of the traditional perception system coordinate. An improved two dimensional coordinate system is proposed to enhance the reliability of target detection. The cross coordinate system is rebuilt by the overlapping parts of adjacent sensing region. A theoretical model of the new coordinate system is established in this paper. The experimental result shows that the design of this improved coordinate system is practical and reasonable,and the target detection accuracy is improved. The new coordinate system has a certain actual application value.
