• Resumen

  • For any measurement of a person’s height in an image, a difference exists between the actual height of the person and the imagemeasurement. In order to gain knowledge about statistical behavior of differences between actual and measured heights it is necessary to make refer-ence recordings, e.g., of test persons under the same recording conditions. To test whether the differences are dependent on camera and furthercircumstances, an experiment was set up which involved the measurement of 22 test persons using three cameras of varying quality. Reproducibilityof measurements per image appears to be strongly dependent on the camera (quality), whereas systematic bias differs with the view point of the cam-era. Operator dependency of the measurement process is found, so its repetition by different operators is recommended
