The invention discloses a six-degree-of-freedom image acquisition mechanism for photoelectric sorting, and the six-degree-of-freedom image acquisition mechanism is provided with an X-direction adjusting screw rod for driving an X-direction adjusting plate to finish advancing or retreating in the X direction, so that the position of a camera in the X direction is adjusted; a Y-direction supporting plate is arranged on an X-direction adjusting plate, a Y-direction adjusting screw rod is arranged in the middle of the top end of the Y-direction supporting plate and connected with a camera Z-direction adjusting base, the Y-direction adjusting screw rod drives the Z-direction adjusting base to ascend or descend in the Y direction, and therefore Y-direction position adjustment of the camera is achieved; a Z-direction adjusting seat is provided with a camera mounting seat plate, a Z-direction translation adjusting seat plate and a Z-direction adjusting screw rod, and the Z-direction adjusting screw rod adjusts the camera mounting seat plate to move forwards or backwards, so that Z-direction position adjustment of the camera is realized. A support is used for connecting and arranging a camera for photoelectric sorting, and six-degree-of-freedom adjustment in three directions is realized, so that the correction precision and efficiency of the camera are improved, accurate focusing imaging of the camera is facilitated, and the rejection rate of other substances during photoelectric sorting is greatly improved.
Description
technical field [0001] The invention relates to a photoelectric device, specifically a six-degree-of-freedom image acquisition mechanism for photoelectric sorting. Background technique [0002] In the sorting industry of agricultural products and industrial products in our country, photoelectric sorting is becoming more and more popular. In the photoelectric sorting process, since the camera, especially the line scan camera, requires high-precision imaging, the orientation and accuracy of the camera are high. In the existing manual correction technology, it is often difficult to achieve accurate correction and the efficiency is extremely low. The accuracy of camera calibration is directly related to the rejection rate of other substances in agricultural products. Therefore, the development of a six-degree-of-freedom adjustment bracket suitable for photoelectric sorting camera calibration can not only improve the accuracy and efficiency of camera calibration, but also greatly...
