Image collecting system

Abstract

The invention discloses an image collecting system which comprises a rigid helmet-shaped support and a plurality of camera shooting devices located on the inner side of the support. A to-be-shot object sample is placed at the optimal shooting position inside the support, the locating camera shooting devices are further selected, the to-be-shot object sample is placed nearby a focus plane, composed of the multiple camera shooting devices, inside the support, continuous shooting is carried out on the to-be-shot object sample through the locating camera shooting devices, after collected image information is analyzed, a locating point corresponding to the to-be-shot object sample is found in the image information, and therefore the practical position of the to-be-shot object sample in a support space formed by the support is determined. According to the image collecting system, the support and / or the to-be-shot object sample are / is moved to reduce the difference between the practical position and the optimal shooting position of the to-be-shot object sample, and then locating shooting is carried out. The image collecting system is particularly suitable for a police system or a security and protection system to shoot the head of a criminal suspect.

Description

technical field [0001] The invention relates to the field of image technology, in particular to an image acquisition system. Background technique [0002] At present, image acquisition technology is more and more widely used. Whether it is image capture on traffic roads or security monitoring in a bank environment, the phenomenon of image acquisition using camera devices is ubiquitous. Similarly, in a public security system or a security system, it is usually necessary to use a video camera to take pictures of the criminal suspect, especially his head, so as to save relevant information. Now, in most cases, the shooting of criminal suspects either stays at the stage of manual shooting, that is, let the suspect stand up and then manually shoot from multiple angles, or put the criminal suspect on a rotating table, fixed The position of the camera device allows the criminal suspect to rotate, so that the camera device collects image information from various angles. The image ...

AI Technical Summary

Problems solved by technology

The image information obtained by the former will vary from person to person, resulting in low shooting quality; although the image information obtained by the latter improves the shooting quality, it is difficult to capture the expression of the criminal suspect from various angles at the same time. In some cases, it will lead to poor 3D reconstruction effect and poor recognition effect

At the same time, in most cases, criminal suspects will not fully cooperate with the requirements of public security personnel or security personnel, which will also make the image collection process difficult, resulting in unsatisfactory shooting effects, and the problem that most of the captured image information is unavailable.
