Method to retrieve target-related metrics, like height and length, in real-time using aerial systems.
PCT/EP2022/069747
The invention relates to a method for determining a height of an object, such as a person or a person’s body part from a single image recorded by an imaging device comprised by an aerial vehicle. Particularly, the invention offers a solution to accurately retrieve the relative camerato-target distance by knowing only the ground distance between two points, a having a ruler object visible in the image. This approach does not require to collect GPS measures or managing geospatial information. It can be therefore deemed suitable for execution by non-technical personnel. Moreover, it can be extremely quick and suitable for automatization.
The invention allows determination of a relative altitude of the aerial vehicle as well as the height of any target, such as a person present in scene form a single image only. The invention further allows measuring a length and an orientation of body parts such as arm span, upper arm, fore arm, hand, thigh, lower leg, foot, length of the head, distance between eyes, etc., whose relationship may give accurate estimation of the stature (anthropometric proportions).
