Abstract

The invention belongs to the field of monitoring and provides a multi-lens panoramic network camera and a stitching method. The multi-lens panoramic network camera comprises: N SENSOR plate modules which are used for imaging, wherein each SENSOR plate module comprises a distortionless high-definition lens and a high-definition light-sensitive imaging chip, the sum of the angles of view of the distortionless high-definition lenses and the included angles between the distortionless high-definition lenses is controlled to form an angle of view of 180 degrees, and N is an integer greater than or equal to 2; an image preprocessing and stitching module which is connected with the N SENSOR plate modules and is used for stitching images picked up by the adjacent SENSOR plates to generate a 180-degree panoramic whole image and transmitting the 180-degree panoramic whole image to a coding module; and the coding module which is connected with the image preprocessing and stitching module and is used for receiving and coding the 180-degree panoramic whole image. The multi-lens panoramic network camera has the following beneficial effects: on one hand, 180-degree monitoring without a dead angle in the horizontal or vertical direction is realized; on the other hand, the camera is high in integrity, convenient to mount and maintain, and low in cost, and advantageous for popularization and use.

Description

technical field [0001] The invention belongs to the monitoring field, in particular to a multi-lens panoramic network camera and a splicing method. Background technique [0002] With the gradual improvement of monitoring facilities, relevant departments have established a monitoring system, which uses panoramic cameras to monitor various areas. At present, on the market, panoramic cameras mainly include fisheye panoramic cameras and multi-lens stitching panoramic cameras, both of which have their own characteristics and applicable occasions. Fisheye panoramic camera: Barrel distortion, the straight lines around the screen will be bent, and algorithm correction is required. After correction, the edges of the image are blurred. Multi-lens stitching panoramic cameras do not have this problem. [0003] However, the existing panoramic camera solutions have obvious stitching seams and low definition, which is not conducive to effective monitoring of targets in large areas, and c...
