文中提出了一种基于对数极坐标映射的目标搜索方法，均匀取样的传感器所获得的像包含有许多相对特定目标搜索而言冗余的信息，对这些信息的处理往往要消耗许多时间。对数极坐标映射可以近似模拟人眼视网膜到条状表皮的映射，利用映射的比例和旋转不变性，可以对大视场目标进行搜索识别。对数极坐标映射将对空间均匀取样得到的图像变换成非均匀取样的图像，减少冗余像素，压缩搜索空间，从而降低运算量，提高系统的目标快速捕获能力 In this paper, a target search method based on logarithmic polar coordinate mapping is proposed. The image obtained by the uniform sampling sensor contains many redundant information relative to the specific target search, and the processing of these information often consumes a lot of time. Logarithmic polar mapping can simulate the human retina to strip epidermal mapping, the use of mapping ratio and rotation invariance, you can search for large field of vision target recognition. Logarithmic polar mapping will be uniform sampling of the space obtained by the image is transformed into non-uniform sampling of images to reduce redundant pixels, search space compression, thereby reducing the computational burden and improve the system’s rapid capture capabilities
