Description

TECHNICAL FIELD

[0001] The utility model belongs to monitoring equipment technical field, concretely relates to a monitoring equipment of infrared and visible light face collection. BACKGROUND

[0002] In face collection technology, visible light image face collection is a key step, which involves locating face in image and outputting the coordinates of face circumscribed rectangle in image. This step depends on the extraction of face texture features in visible light image. However, due to the limitation of camera dynamic range, when the light condition is poor, such as too weak or too strong, the contrast of image will be compressed, resulting in that face texture features become unobvious, thereby affecting the effect of face detection. Therefore, before using existing algorithm for face detection, it is usually necessary to pretreat the input visible light image to improve image quality and make face texture features clearer. At the same time, infrared image face collection becomes more and more important. Infrared imaging technology can provide clear image of face under poor light condition, so it is possible to search face area matching face in visible light image on infrared image. In order to achieve this goal, correlation filter detector can be used to collect and monitor face on infrared image, and by integrating this kind of technology in monitoring equipment, this method can not only improve the accuracy of face collection, but also realize stable face detection and tracking under various light conditions.

[0003] The existing spherical monitoring equipment, when installing, usually uses double-sided adhesive cotton as the adhesive means when the installation environment allows wall bonding. However, in actual application, it often encounters the situation that higher installation strength is required or the installation surface material is not suitable for bonding. At this time, it has to rely on a special mounting frame to realize fixation. The existing spherical monitoring equipment lacks flexibility in structure and cannot adapt to the needs of different installation surfaces only by relying on its own structure. Whether it is a smooth wall or rough concrete, the equipment cannot make corresponding adjustment, which greatly limits its application range. Therefore, the existing spherical monitoring equipment has great limitations in installation and use, and the function is relatively single. UTILITY MODEL CONTENTS
