复杂现场外弧形显示屏的逐点校正

摘要

The LED display correction has two modes: factory mode and on-site mode. Using on-site mode, the correction of outdoor displays is more effective and efficient. For improving the uniformity of old displays, the on-site mode also is the most low-cost and high-speed solution. But there are various of difficulties cause of the complexity of environment, such as block of trees and wires, hard to locate the measuring position, multi- positions data merge, bad environment conditions as so on. The on-site correction of raised arc-shaped display is especially challenging. In this paper, we will see all questions listed above through a typical case, and share our solutions.%逐点校正根据应用场合可分为工厂校正和现场校正，户外显示屏通常现场的校正效果更理想，效率也更高。对于已使用一段时间的显示屏的均匀性提升，现场校正也是最经济快捷的解决方案。然而，由于环境条件的复杂性，现场校正存在着各种各样的实际困难，包括树木或电线遮挡、校正机位选择困难、多机位数据融合、环境条件恶劣等等。外弧形显示屏的现场校正，更是难题中的难题。本文通过一个典型实际案例对以上种种问题加以分析，并提出我们的解决方案。
