[0028] Example 1

[0029] figure 1 Shown is a schematic structural diagram of the multiple reflection type image visibility measurement system provided by the present invention. The measurement system comprises a resolution plate (1), a first plane mirror (2), a second plane mirror (3), a first digital camera (4), a second digital camera (8) and a computer processing system (Fig. omitted). The first plane reflection mirror (2) and the second plane reflection mirror (3) constitute an optical reflection system, and (5), (6) and (7) are the reflected images of the resolution plate.

Abstract

The invention relates to a multiple reflection type image visibility measuring method to solve the problems that during visibility measurement, measurement results are indirect and instruments occupy large spaces. A resolution panel is adopted as a target, two parallel plane mirrors are placed at two ends of a measurement device at small angles, and a digital camera acquires images of the resolution panel after multiple reflections. The visibility is measured through analysis of minimum line pairs in the images of the resolution panel.

Description

【Technical field】: [0001] The invention relates to a multi-reflection image visibility measurement method, which is suitable for visibility measurement in the field of environmental monitoring. 【Background technique】: [0002] With the rapid development of modern industry and technology, the problem of environmental pollution has become increasingly prominent, and the measurement of visibility is becoming more and more important to people's life and travel. [0003] Visibility can generally be measured visually, or by measuring instruments such as atmospheric transmissometers and scatterometers. [0004] The visual method is intuitive and measures the direct result of visibility. However, the boundary between visible and invisible is not very clear during observation, and the judgment of the outline from clear to fuzzy can only be judged by human eyes and subjectively. And due to the influence of vision, interpretation ability, light source characteristics, habits, etc., i...
