1. A method of calculating a bleeding site and a trajectory of a bloodstain scattered by impact, the method comprising:
obtaining, by an electronic device calculating the bleeding site and the trajectory of the bloodstain scattered by impact, captured image information including a captured image and a three-dimensional (3D) coordinate value of each of two or more bloodstains scattered by impact;
analyzing the obtained captured image information, by the electronic device, and calculating a collision angle and measuring a direction angle of each of the two or more bloodstains scattered by impact;
calculating, by the electronic device, the 3D coordinate value of the bleeding site based on the assumption that drops of blood fly in a straight line;
calculating, by the electronic device, a trajectory of a drop of blood under an influence of gravity and air resistance based on the calculated 3D coordinate value of the bleeding site; and
displaying and outputting, by the electronic device, a linear trajectory of the drop of blood and a parabolic trajectory considering gravity and air resistance of the drop of blood on a 3D space.
