Embodiment 1
[0026] Such as Figure 1 to Figure 5 As shown, the contrast enhancement device includes a lifting mechanism and a rotating arm mechanism arranged on the lifting mechanism. The rotating arm mechanism is equipped with a contrast enhancing mechanism for blocking the front side of the image acquisition mechanism to filter out corresponding light waves. The contrast enhancing mechanism It includes a dark color filter module 9 for filtering dark light waves and a light color filter module 7 for filtering light color light waves. Switching between each other during the rotation; also includes a control mechanism 1 for receiving and processing the image information upstream of the conveyor belt, and controlling the action of the lifting mechanism and the rotating arm mechanism as a whole according to the judgment result of the image information. The contrast enhancement device also includes an image collection mechanism for collecting image information through the contrast enhancement...

The invention relates to a contrast enhancement device applied on a conveyor belt. A contrast enhancement device applied on a conveyor belt includes a lifting mechanism and a rotating arm mechanism arranged on the lifting mechanism, a contrast enhancing mechanism is installed on the rotating arm mechanism, and the contrast enhancing mechanism includes a dark color filter module and a light color filter module, The dark filter module and the light filter module switch between each other during the rotation of the rotating arm mechanism; it also includes a device for receiving and processing the image information upstream of the conveyor belt, and overall controlling the lifting mechanism and the rotating arm mechanism according to the judgment result of the image information. The control mechanism for the action of the arm mechanism. The contrast enhancement device of the present invention improves the contrast of image information, avoids the problem that the color of the object will overlap with the color of the conveyor belt, and causes the objects on the conveyor belt to be clearly distinguished, and provides accurate and clear images for the rear actuator Instructions enable the production line to run more accurately and efficiently.
Description
technical field [0001] The invention relates to the technical field of visual effect equipment, in particular to a contrast enhancement device applied on a conveyor belt. Background technique [0002] Contrast refers to the measurement of different brightness levels between the brightest white and the darkest black in the light and dark areas of an image. The larger the difference between white and black, the greater the contrast, and the smaller the difference, the smaller the contrast. The impact of contrast on visual effects is very important. Generally speaking, the greater the contrast, the clearer and more eye-catching the image, and the brighter the color; while the smaller the contrast, the whole picture will be in a gray state, and the image in the picture will become blurred. Hard to make out. Therefore, high contrast is very helpful for image clarity, detail performance, and gray level performance. [0003] In a modern production line, in order to grasp the situ...
