【摘要】 提出了依据球场平面照度不均匀度最小的约束条件排列照明光源的方法.将光源依照度大小非递增排序,根据照度与空间距离变化规律和光源架与篮球场的具体尺寸,采用贪心算法设计技术,依据使球场平面上最小照度取最大值和最大照度值取最小的原则,依次排列照明灯.计算表明,此方法降低了球场照度的不均匀度,提高了篮球场照度的均匀性.更多还原

【Abstract】 A method of arranging illuminators is given which is based on the minimum of illumination ununiformity on the ball field.According to the rule of illumination changing due to distance variety and dimensions of illuminations and basketball field,illuminators are in turn arranged on the basis of the rule that is the minimum of the illumination on the field is maximized and the maximum is minimized.The algorithm is designed with the greedy design technology.Calculations show that this method decreases the field’s illumination ununiformity,and increases the uniformity.更多还原
