Abstract
The methods of measurement of the microscopic and macroscopic morphology of feathers are discussed. A three-dimensional coordinate measuring machine and optical microscope are used together, that is, the macroscopic size of the feather is measured using the detection technology of the three-dimensional coordinate measuring machine, and the optical microscope is then used. The static accuracy error produced by the measurement result is (2.9064-4.0235) um, which is much smaller than the measurement error of 0.5 mm of the millimetre measuring ruler; The microscopic dimensions of the plume of the feather plume are measured by microscopy: the result is accurate to micron level, and the gradated scale is accurate to ± 0.5 mm. This study contributes to basic theoretical research in the fields of feather morphology, fractal analysis, and ecology.
