Problems solved by technology

The camera is an important part of the color sorter equipment, and the calibration of the camera is the most important work, which directly affects the effect of the color sorter. At present, the calibration of the color sorter camera on the market is to stick welding rods on both sides of the slideway. On the other hand, the relative position is not accurate enough, and the “white balance” is calibrated with a 24-color card close to the slideway, which is not conducive to the value of the “white balance”, and the calibration devices required for different structural types of equipment are different, which is inconvenient to carry

Embodiment 1

[0024] see figure 1 As shown, a color sorter camera calibration instrument is used for camera calibration of side-blown crawler machines in color sorters. The nozzle beam 1 is provided with a color card installation mechanism, and the color card installation mechanism is located on the center line of the nozzle beam 1. The color card The installation mechanism is used to adjust the aperture and white balance. The color card installation mechanism includes a color card installation block 2 and a color card 3. The color card installation block 2 is installed on the nozzle beam 1 and is located at the center line of the nozzle beam 1. The color card A color card 3 is installed on the mounting block 2, and a scale plate 4 is installed on the nozzle beam 1 and on both sides of the color card installation mechanism. The scale plate 4 is arranged symmetrically with respect to the center line of the nozzle beam 1, and a focusing plate 5 is installed on the scale plate 4. , the focusin...

Embodiment 2

[0026] see Figure 2-3 As shown, a color sorter camera calibration instrument is used for camera calibration of tea color sorter. The nozzle beam 1 is equipped with a color card installation mechanism, which is located on the center line of the nozzle beam 1. The color card installation mechanism is used to adjust For the adjustment of the aperture and white balance, since the structure of the tea color sorter is different from that of the side-blown crawler color sorter in Embodiment 1, the color card installation mechanism in this embodiment not only includes the color card installation block 2 and the color card 3, but also includes Color card fixing block 10, counterweight 11, the color card fixing block 10 is installed on the nozzle beam 1 and located at the center line of the nozzle beam 1, the color card fixing block 10 is in the shape of "L", which is convenient for installing the color card mounting block 2. The color card installation block 2 is set on the color card...

Embodiment 3

[0028] see Figure 4-5 As shown, a color sorter camera calibration instrument is used for camera calibration of rice and miscellaneous grain color sorters. The nozzle beam 1 is provided with a color card installation mechanism, which is located on the center line of the nozzle beam 1. The color card installation mechanism It is used to adjust the aperture and white balance. The structure of the color card installation mechanism in this embodiment is the same as that of the color card installation mechanism in Embodiment 1. The color card installation mechanism includes a color card installation block 2 and a color card 3. The installation block 2 is installed on the nozzle beam 1 and is located at the center line of the nozzle beam 1. The color card installation block 2 is equipped with a color card 3. On the nozzle beam 1 and located on both sides of the color card installation mechanism, there are scale plates 4 and scales respectively. The plate 4 is arranged symmetrically ...

Abstract

The invention discloses a camera correcting instrument of a color sorter. The correcting instrument comprises a nozzle cross beam, a color card installing mechanism is arranged on the nozzle cross beam, and the color card installing mechanism is located on the center line of the nozzle cross beam, ruler plates are arranged on the nozzle cross beam and located on the two sides of the color card installing mechanism correspondingly, and the ruler plates are symmetrically arranged relative to the center line of the nozzle cross beam; and focusing plates are installed on the ruler plates, movableplates are arranged at the two ends of the nozzle cross beam correspondingly, and the movable plates are symmetrically arranged relative to the center line of the nozzle cross beam. The camera correcting instrument of the color sorter is simple in structure and convenient to install, the correction precision of the camera of the color sorter is greatly improved, and the color selection effect is improved.

Description

technical field [0001] The invention relates to a camera calibration device for a color sorter, in particular to a camera calibration device for a color sorter. Background technique [0002] Photoelectric color sorter is a kind of non-destructive sorting equipment used for quality detection and classification of bulk materials. It is widely used in grain, food, pigment chemical industry and other industries. , all kinds of beans, all kinds of rice, ore, pepper, pepper, garlic, melon seeds, raisins, seeds, traditional Chinese medicine, sea rice, shrimp skin, clove fish, glass, metal, same-color rods and other malignant impurities and special materials The effects are very significant, reaching the international leading level. The color sorter is mainly composed of feeding system, optical detection system, signal processing system and separation execution system. The camera is an important part of the color sorter equipment, and the calibration of the camera is the most impo...
