Reflective outer panoramic lens suitable for industrial detection

Abstract

The invention discloses a reflective outer panoramic lens suitable for industrial detection. The lens comprises a telecentric lens, a second shell sleeves the top end of the telecentric lens, a fourthshell sleeves the tail end of the telecentric lens, a third shell sleeves the telecentric lens above the fourth shell, and a first shell is fixed at the top end of the second shell. The device further comprises a first mounting plate, a second mounting plate, a first reflector, a triangular prism, a second reflector, a third reflector and a fourth reflector. Compared with the prior art, the reflective outer panoramic lens suitable for industrial detection can detect the outer surfaces of parts, especially bearing products, appearance panoramic imaging of the bearing products is achieved through the telecentric lens, the triple prism, the first reflector, the second reflector, the third reflector and the fourth reflector, and the imaging quality is high; and the lens is simple in structureand low in cost.

Description

technical field [0001] The invention relates to the field of optical lenses, in particular to a reflective outer panoramic lens suitable for industrial inspection. Background technique [0002] Panoramic lens is a device that uses panoramic technology to obtain a full 360° field of view in the horizontal direction and a certain angle in the vertical direction. This imaging method can provide all-round information of the object and the environment 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 lenses is increasing. [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. Bearing inspection lenses on the market are often expensive and have low detection accurac...

AI Technical Summary

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.
