Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shooting support, in particular to a high-rise building glass bullet hole outside shooting support. BACKGROUND

[0002] In criminal investigation practice, photographing bullet holes on glass is a key link of on-site investigation. The morphological characteristics of bullet holes, especially the difference between their entrance and exit (such as the smooth and flat edge of the entrance side and the funnel-shaped peeling of the exit side), are the key evidence for judging the direction of bullet penetration, shooting angle and position. In order to accurately record the characteristics of bullet holes and ensure the accuracy of measurement data, the basic principles of evidence photography must be followed, that is, the optical axis of the camera lens must be perpendicular to the glass plane to maximize the avoidance of perspective distortion.

[0003] At present, for the shooting of bullet holes on the outside of low-rise building glass, the technical personnel can usually make the camera perpendicular to the glass surface by directly approaching or using a simple support, so as to obtain the required photos. However, when the bullet hole is located on the outside window of a high-rise building, the traditional shooting method faces severe challenges. The technical personnel need to lean out of the window or use high-altitude operation equipment (such as a hanging basket or a high-altitude operation vehicle) for operation, which has a great risk of falling. At the same time, calling large professional equipment also consumes time and effort, and the extended height is also limited. In addition, there is also a scheme of using a drone to carry a camera for shooting. However, when the drone is close to the high-rise building at a short distance, it is affected by wind disturbance, GPS signal blockage and other factors, and its hovering stability is poor, which has a risk of collision. Moreover, its control precision is difficult to achieve accurate perpendicularity and focusing with the glass surface, and the shooting effect is also not ideal.

[0004] Therefore, the existing technology lacks a high-rise building glass outside bullet hole special shooting scheme that can balance operation safety, high efficiency and convenience, and obtain high-quality, non-distorted images.
