Abstract
A method of calculating a bleeding site and a trajectory of a bloodstain scattered by impact includes: obtaining, by an electronic device calculating the bleeding site and the trajectory of the bloodstain scattered by impact, captured image information; analyzing the obtained captured image information, by the electronic device, and calculating a collision angle and measuring a direction angle of the bloodstain scattered by impact; calculating, by the electronic device, a coordinate value of the bleeding site by using a linear trajectory method; calculating, by the electronic device, a trajectory of a drop of blood based on the calculated coordinate value of the bleeding site by using a parabolic trajectory method considering gravity and air resistance; 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.
