【摘要】 从图像特性的角度,研究了匹配实时图对比度变化对雷达景象匹配可靠性的影响,并根据匹配过程中的特点,从理论上推导出了对比度和相关系数的定量关系,通过大量实践表明,提高实时图的对比度可以提高雷达景象匹配的可靠性,通过对比度来增强匹配可靠性是一种行之有效的方法。更多还原

【Abstract】 The matching reliability by researching on the contrast of gray scale of real time radar image and the character of matching process is analysed.The fix quantity relation between the contrast of gray scale and Nprod is given.It is proved by a great deal of experimentations that the method based on contrast of gray scale of real time image is an effective way to improve the reliability of scene matching of radar image.更多还原
