3results about How to "Avoid imprecision" patented technology

The invention provides a spray head assembly correction method, electronic equipment and a computer storage medium. The nozzle assembly correction method is applied to the 3D printing equipment. The nozzle assembly correction method comprises the following steps: controlling an acquisition assembly to acquire a printing platform printed with a corrected object to obtain an initial grayscale image; establishing a rectangular plane coordinate system based on the initial grayscale image; image processing is carried out on the initial grayscale image to obtain a target grayscale image, and a first line segment in the target grayscale image is parallel to any coordinate axis of the rectangular plane coordinate system; acquiring a pixel characteristic curve matched with the target grayscale image, a first length of the first line segment and a second length of the second line segment; calculating nozzle correction parameters based on the pixel characteristic curve, the first length and the second length; the showerhead assembly is corrected using the showerhead correction parameter. According to the method and the device, the spray head assembly can be accurately corrected, and the problem of unqualified printing quality caused by deviation of the uncorrected spray head assembly during printing of the spray head assembly is avoided.

The application relates to the field of automatic driving of an automobile, and discloses a vehicle lateral control method and device, computer equipment and a storage medium, the method comprising the following steps: acquiring vehicle preset parameters, space prediction parameters and prediction custom parameters, and configuring a state prediction model according to the prediction custom parameters; processing the vehicle preset parameters and the space prediction parameters through the state prediction model to obtain a prediction state quantity; acquiring a path reference sequence, determining a position prediction error according to the path reference sequence and the prediction state quantity; acquiring a custom weighting matrix, and determining a control gain according to the custom weighting matrix and the prediction state quantity; determining a prediction control increment according to the position prediction error and the control gain; acquiring a current control quantity, and determining a target control quantity according to the prediction control increment and the current control quantity. The application can improve the accuracy and stability of vehicle lateral control.

The utility model discloses a kind of green building construction wastewater recovery equipment, comprising: separation mechanism, including reaction tank, shunt box and lower intercommunication separation screen cylinder, the first rotating shaft is rotatably arranged in the reaction tank, stirring vane is installed on the rotating shaft outside, the inside of separation screen cylinder is rotatably arranged with spiral conveying blade, the spiral conveying blade is fixed on the output end of servo motor.The wastewater of the utility model is discharged into separation screen cylinder after preliminary treatment by reaction tank, large particle impurities are intercepted by screen cylinder, at this time, rotating spiral conveying blade will continuously push the impurities in screen cylinder inner wall and bottom to one end, finally automatically discharged through deslagging pipe, fall into the impurity collection box below, simultaneously, treated clean water passes through screen cylinder and flows into wastewater collection box below, and then without manual intervention, greatly reduce human burden, significantly improve cleaning efficiency, ensure that equipment continues stable operation.
