Abstract

本发明涉及投影仪技术领域，尤其涉及一种基于环境光动态感知的投射参数匹配方法及影像投影仪，该方法获取影像投影仪所处环境的历史光源信息以及当前光照类型。结合历史光源信息中的三种环境类型的光学特性与投射参数匹配方案数据库，确定不同环境的投射参数需求，并依当前光照类型匹配对应方案。获取设备在环境光影响下的亮度衰减和色偏日变化规律，优化投射参数匹配方案。建立融合环境光强度、色温及设备类型的光环境预测模型，输出不同场景下的投射参数预测结果。依据优化后的方案获取实时投射参数，与预测结果比对，通过数据积累和反馈持续完善匹配方案及参数阈值，形成自适应的投射参数匹配闭环，实现复杂光环境下投影参数的动态精准匹配。
