Abstract
Aiming at traditional horizontal equal-angle scanning method’s disadvantage of measurement error, a high precision equal-angle scanning method is proposed, the proposed method establishes a tilt scanning model by the following steps: introducing height variable, precisely calculating the viewing angle, building scanning model. The model is used to calculate scanning position on rotary kiln’s surface, which helps to locate and track temperature variation. The experiment shows that the proposed method can effectively improve the precision of temperature spots’ location on the rotary kiln surface.
