Problems solved by technology

[0004] At present, there is no specific calibration method for how to calibrate the assembly error of the panoramic camera quickly, simply, and accurately. Therefore, a quantifiable calibration method for the assembly error of the panoramic camera is urgently needed, and the allowable error range of the panoramic camera is determined according to the stitching algorithm. , and then guide industrial production

Embodiment Construction

[0055] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0056] A panoramic camera refers to the use of multiple cameras to shoot a space scene at the same time and output a 360-degree panoramic video in real time. A panoramic camera has at least two or more cameras, the core technology of which is the real-time stitching of multiple videos.

[0057] Since the panoramic camera uses multiple cameras to shoot 360-degree space scenes, the partially overlapping areas collected by ...

Abstract

Disclosed are a method and system for calibrating an assembly error of a panorama camera. The method comprises the steps of establishing a monocular calibration model, establishing a binocular three-dimensional calibration model, and calculating the assembly error of the panorama camera based on the monocular calibration model and the binocular three-dimensional calibration model. Based on the calibration model of a standard camera, the angle between adjacent camera coordinate axises and the error of rotation and translation of all coordinate systems are calculated, and the assembly error of the panorama camera can be accurately and concisely described through the two parameter indexes. Furthermore, the invention provides a feasible method for solving the assembly error. The splicing accuracy problem caused by the camera assembly error is preferably solved in production and application of the panorama camera, therefore, the splicing effect is improved.

Description

technical field [0001] The invention belongs to the field of computer vision, and in particular relates to a method and system for calibrating assembly errors of panoramic cameras. Background technique [0002] A panoramic camera refers to the use of multiple cameras to shoot a space scene at the same time and output a 360-degree panoramic video in real time. A panoramic camera has at least two or more cameras, the core technology of which is the real-time stitching of multiple videos. [0003] Since the panoramic camera uses multiple cameras to shoot 360-degree space scenes, the partially overlapping areas collected by adjacent cameras are used for image fusion, and finally the partially overlapping images collected by each camera are spliced ​​into a large seamless high-resolution image. image. Panoramic camera image stitching technology greatly depends on the size of the overlapping area between the cameras, and the size of the overlapping area collected between adjacen...
