Space registering method based on panoramic all-in-one speed dome camera

Abstract

The invention relates to a method for image registration, in particular to a space registering method based on a panoramic all-in-one speed dome camera. The technical problem that an existing panoramic all-in-one speed dome camera can not be accurately located is solved. The space registering method based on the panoramic all-in-one speed dome camera comprises the following steps that step one, a panoramic cylindrical coordinate system, a speed dome camera coordinate system and a spherical surface coordinate system are established; step two, change from the panoramic cylindrical coordinate system to the spherical surface coordinate system is conducted and change from the speed dome camera coordinate system to the spherical surface coordinate system is conducted; step three, characteristic points of a whole-screen image and characteristic points of a speed dome camera image are matched; step four, according to the matched characteristic points, a changing matrix is solved; step five, a point or a zone needing to be observed is selected from the panoramic image, and the rotating angle of a speed dome camera is calculated. The rotating angle of the speed dome camera can be rapidly and accurately calculated, the local scene is shot, and the space registering method based on the panoramic speed dome camera all-in-one machine has the advantages of improving the performance of a monitoring device and satisfying the requirements of a user.

Description

technical field [0001] The invention relates to an image registration method, which belongs to the field of image information processing, in particular to a spatial registration method based on a panoramic high-speed dome all-in-one machine. Background technique [0002] In recent years, with the development of video surveillance technology, the market demand for wide-angle panoramic surveillance equipment is increasing. Panoramic monitoring technology uses fisheye lenses or catadioptric omnidirectional imaging devices to generate panoramic video images containing all-round scene information, which can realize the display of large-field and wide-view scene images, and has very important application value in the field of security monitoring. [0003] The panoramic speed dome all-in-one machine is a new type of panoramic monitoring equipment, which is composed of a panoramic camera 1 and a high-speed dome camera 2, such as figure 1 shown. Among them, the panoramic camera ado...
