Embodiment Construction

[0025] 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 conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] In some special applications, the detection accuracy of the object is very high, and the highest pixel of the existing optical hardware camera can only reach tens of millions, and this tens of millions of pixels is very expensive, for small field of view In terms of imaging, ordinary megapixel cameras can meet customer requirements, but if customers require large field of view imaging and resolution at the micron level, it is difficult for existing area array cameras to achieve such a high resolution .

[0027] Such as figure 1 As shown, the embodiment of the present invention provides a l...

Abstract

The invention belongs to the field of vision processing and provides an imaging method of a large view field. Products to be detected are divided into a plurality of small view field zones by XY galvanometer scanning, and scanning information is fed back to a CCD camera of an image collecting system for imaging; and by small view field quick scanning of an XY galvanometer, the CCD camera can shoot N small images, and through an image processing method, the N small images are spliced into a whole large image. The XY galvanometer is very high in scanning speed, so that under the same camera condition, small view field imaging is achieved, system detecting accuracy is greatly improved, according to XY galvanometer scanning, a common camera and a lens can be used for imaging, price is reasonable, the requirements for high accuracy, high efficiency and large view field imaging of current equipment can be met, and the embodiment of the invention further discloses an imaging device of the large view field.

Description

technical field [0001] The invention relates to the field of vision-based processing, in particular to an imaging method and device based on an XY vibrating mirror self-scanning large field of view. Background technique [0002] In the processing of existing laser equipment with visual detection function, the quality requirements of the equipment are becoming more and more stringent, especially the detection accuracy of the equipment is getting higher and higher, and the detection accuracy of the equipment is related to the resolution of the camera itself. The higher the rate, the higher the detection accuracy. At present, the highest resolution camera can reach 10 million pixels, but it is difficult to find a lens that can match this high resolution, and the higher the resolution, the more expensive the camera and lens are, and the cost is very high; For a low-cost, lower-resolution camera, the higher the visual detection accuracy, the smaller the field of view will become...
