Referring to fig. 1 to 5, the splicing camera according to the embodiment of the present invention will be clarified in the following description, wherein the plurality of lenses 21 arranged at the included angles enlarge the field angle of the lens assembly 20, and are combined with the control chip 30 to output the high-definition spliced image, thereby satisfying the requirement of high-definition monitoring.

As shown in fig. 1, the splicing camera of the present invention includes a housing 10, a lens assembly 20 and a control chip 30, wherein the lens assembly 20 is disposed at the front end of the housing 10 and connected to the control chip 30; the lens assembly 20 comprises a plurality of lenses 21, the lenses 21 are sequentially arranged at preset included angles to form the lens assembly 20 capable of collecting images within a range of more than or equal to 150 degrees, and the included angles between the lenses 21 are the same; images collected by all the lenses 21 are spliced by the control chip 30 and then spliced images of 8K image quality to 12K image quality are output.

The included angle between the lenses 21 is set according to the viewing angle of the lenses 21 themselves and the required total viewing angle, as in the specific example shown in fig. 2, 4 plane lenses 21 are adopted, and the included angle of each lens 21 is set to be 30 °, so that the total viewing angle can reach 180 °, and the imaging effect of some marginal viewing angles is poor, therefore, the total viewing angle can be set to be 150 °, which is more stable, and the imaging image quality is clearer.

Preferably, in some embodiments, the lens 21 is a flat lens 21, and compared with the fisheye lens 21, the imaging quality of the flat lens 21 is more stable, the distortion is smaller, and the resolution is higher, so that the processed and output spliced image is clearer. More specifically, the lens 21 is a flat lens 21 with a focal length of 8mm and a resolution of 1200 ten thousand, which can meet the use requirements of high-precision monitoring equipment.

Since the resolution of the lens 21 is high and the output data stream is large, the lens assembly 20 includes an SD memory card, which is a high-speed SD memory card and meets the storage requirement for large capacity and high transmission rate. Alternatively, the lens assembly 20 includes a network transmission module, which transmits data to the control chip 30 in real time, so as to relieve the storage pressure of the lens 21. Preferably, the lens assembly 20 may include both the SD memory card and the network transmission module, so as to handle a larger data volume, greatly improve the data transmission rate, and meet the use requirement. Preferably, the control chip 30 adopts a haisi Hi3559A high-speed processing chip to ensure real-time property of image quality of splicing and output, and the built-in image splicing processing software is multi-splicing camera equipment-side software used for processing high-definition images, splicing the images and outputting the spliced high-definition images.
