Research on Height Measure Based on Shadow Feature

Abstract:

At present, the height measure is an important content of image processing. But the height is determined by solar height angle achieved by look-up table, and the method is imprecise and inconvenient. To overcome such drawbacks, a novel determination method was proposed in the paper. First, the imaging time is adjusted to Solar Time. Then, the solar height angle at imaging time is calculated. Finally, the height of an object is calculated based on solar height angle and shadow length. The theoretical analysis and experiment results show that the proposed method is more effectual.
