Transmission type outer panoramic lens suitable for industrial detection

Abstract

The invention discloses a transmission type outer panoramic lens suitable for industrial detection, which is used for being installed at the front end of a camera. A first plane lens is installed inside the front end of the camera, and the transmission type outer panoramic lens comprises a first lens cone, a second lens cone, a third lens cone, a first lens cone and a camera connecting ring. A camera is in threaded connection with the top end of the first lens barrel through a camera connecting ring, and the lower end of the first lens barrel is fixed at the top end of the second lens cone. The tail end of the second lens cone is fixed in the top end of the third lens cone. Compared with the prior art, the transmission type outer panoramic lens suitable for industrial detection can detectthe outer surfaces of parts, especially bearing products, focusing is conducted through the lenses in the first lens cone and the third lens cone, the first focusing ring, the second focusing ring andthe third focusing ring, and appearance panoramic imaging of the bearing products is achieved. The transmission type outer panoramic lens is extremely low in aberration and relatively high in imagingprecision; and the lens is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the field of optical lenses, in particular to a transmission type external panoramic lens suitable for industrial detection. Background technique [0002] Panoramic lens is a device that uses panoramic technology to obtain a full 360° in the horizontal direction and a certain angle of view in the vertical direction. This imaging method can provide all-round information of objects and environments in real time, and strive for subsequent image processing and analysis. time. With the rapid development of digital image processing technology, the demand for panoramic lens is increasing day by day. [0003] With the development of science and technology, the degree of industrial automation has gradually deepened. In terms of industrial inspection, with the development of CCD / CMOS cameras, machine inspection has gradually replaced manual inspection. At present, the inspection lenses for bearings in the market are often expensive and...

Problems solved by technology

At present, the inspection lenses for bearings in the market are often expensive and the detection accuracy is not high, and in the appearance inspection of bearings, it is often necessary to use multiple lenses and obtain accurate bearing appearance data through post-stage image processing.

At present, the common panoramic lens on the market is a fisheye lens, but the fisheye lens produces barrel distortion, which makes the image deformed and is not suitable for industrial appearance inspection.
