摘要
为保证太阳光实时垂直照射太阳能接收板,提高太阳能利用率,提出基于投影图像识别的太阳光跟踪技术。通过物体投影图像的轮廓识别,获得投影图形的几何参数,并以此计算太阳光的入射角度,采用当前通用的双轴跟踪方式,以太阳光为数据基础,实现太阳光实时跟踪的目的。追光精度分析表明,该技术具有较高的跟踪精度,可满足实际需要。
Sunlight tracking technique based on projected image identification is suggested with the purpose of ensuring that sunlight can vertically beat down on dash receivers all the time so as to make a better use of solar energy. By means of contour identification of projected images, geometrical parameters of the projected images can be obtained by which we can figure out the incident angle of sunlight. With the sunlight data, the widely-used biaxial tracking mode is employed to achieve the final aim of tracking sunlight all the time. Analysis done on sunlight tracking accuracy demonstrates that this technique is superior in high tracking accuracy and can meet the practical demand.
