The invention discloses an image blurring direction identification method based on a characteristic block direction differential. The method comprises the steps of calculating local deviation of point coordinates of each pixel of a target image, selecting first M points with the maximum local deviation, randomly selecting an N point serving as a characteristic block construct point in the M points, wherein the M and the N are positive integers, the M is larger than the N, and the N is larger than 1, regarding coordinates of the characteristic block construct point as a center, building the square characteristic blocks with the edges as C pixels and the areas as C*C, wherein the C is a positive integer, identifying a blurring direction angle of each characteristic block by a directional differentiation, recording the blurring direction angles of all the characteristic blocks, and judging and obtaining the blurring direction angle of the target image according to the blurring direction angles of all the characteristic blocks. The image blurring direction identification method processes identification of the burring direction of the target image in a simplified mode, reduces operation quantity and operation time, and obtains the accurate blurring direction by the calculating mode of multiple weighted means for the directional differentiation.

The invention discloses a plant point cloud acquisition registration and optimization method based on a TOF camera, comprising the following steps: (1) placing the measured plant on a turntable, adjusting the TOF camera angle of view and aligning it with the measured plant; 2) Turn on the turntable to make it rotate automatically, and at the same time, the TOF camera collects the point cloud data of the measured plant at intervals; (3) Perform real-time preprocessing on each frame of point cloud data collected by the TOF camera; Two frames of point cloud data are registered and optimized, and then integrated to obtain complete plant point cloud data; (5) Statistical filtering is used to remove discrete noise in the number of plant point clouds obtained by registration and optimization processing, and the final point cloud data. The method of the invention can effectively solve the stratification phenomenon of local point clouds.

The invention relates to a process for processing leather trimming stitches for leather products, which uses a leather trimming stitching processing device for leather products. The leather trimming stitching processing device includes a workbench and a clamping mechanism. The workbench is installed on the existing ground, and the upper end of the workbench is provided with a clamping mechanism. The present invention adopts a multi-adjustment design concept for leather cutting and suture processing. The implementation of the clamping treatment can also smooth the leather to maintain the best flatness of the leather, thereby improving the overall cutting quality of the leather. At the same time, the rolling and smoothing structure is adopted to reduce the appearance of the structure by generating rolling friction The probability of motion jamming is reduced, and the device as a whole can also realize the conversion between the dual modes of vertically cutting leather and horizontally cutting leather, thereby greatly improving the adaptability of the device to leather cutting requirements.

The invention discloses a power overshoot protection circuit for a digital television power amplifier, which comprises a power detection circuit and an overshoot detection circuit, wherein the time constant of the power detection circuit is controlled by an external discrete device, and the power detection circuit is used for selecting the time constant to ensure that power overshoot of digital television signals of different modes can be detected; and the overshoot detection circuit comprises a see-saw amplifier with a high pass characteristic, a hysteresis comparator, a reference voltage source and a reset circuit. The power overshoot protection circuit has the beneficial effects that the time constant of the power detection circuit is optimally designed, the smooth function is taken on the random fluctuation of the signal amplitude, meanwhile, the characteristic of power overshoot is kept, so that the false operation due to the pseudorandomness of the digital television signal can be avoided, the detection of the power overshoot can be realized; the circuit is simple; the cost is low; and the power overshoot protection circuit can be conveniently suitable for an emitting system power amplifier adopting the China digital television standard.

The present invention provides a method, device, and storage medium for predicting traffic trends based on historical traffic, including the steps of: reading historical traffic data information, the historical traffic data includes actual traffic data of multiple historical unit time periods, and the multiple Associate the actual flow data of a historical unit time period; determine the effective historical flow data information; determine the forecast flow data of the forecast unit time period, the forecast flow data of the forecast unit time period and the actual flow data of the multiple historical unit time periods Associated traffic data. The invalid historical flow data is eliminated to eliminate the influence of the invalid historical abnormal flow data on the calculation results, and then the prediction time point is determined and the flow data is predicted to improve the accuracy of the flow forecast.
