A method of image information enhancement in radiography relates to image information processing techniques in radiography. The method comprising steps of: normalizing an acquired image A(x,y) to form a normalized image B(x,y); filtering the normalized image B(x,y) by a low-pass filter to obtain an filtered image C(x,y); calculating a relative standard deviation for each pixel in the image A(x,y), three times the relative standard deviation being an edge threshold for each pixel; thresholding a difference image obtained by subtracting the filtered image C(x,y) from the normalized image B(x,y) by using the edge threshold for each pixel to form a threshold-processed image D(x,y); enhancing a contrast of the threshold-processed image D(x,y) by using a non-linear function to form a contrast-enhanced image E(x,y); determining a enhancement coefficient a(x,y); obtaining a edge-enhanced image F(x,y) by multiplying the enhancement coefficient a(x,y), the contrast-enhanced image E(x,y) and the filtered image C(x,y); and generating a resulting image by multiplying a sum of the edge-enhanced image F(x,y) and the filtered image C(x,y) with the maximum value Amax As compared with the prior arts, the inventive method has a fast processing speed for image information enhancement and a simple algorithm, images clearly, eliminates noises in the images, and satisfies the requirements of relatively more enhancement to the contrast of the dark regions in the scanned images.

The invention discloses a method for testing and analyzing an automatic driving system, which includes loading data to be evaluated, specifying evaluation indicators and evaluation scenarios required for evaluation; loading standard scene data as true value data according to the evaluation scene; obtaining feature quantities of the data to be evaluated; Feature quantity consistency and / or position consistency pair the data to be evaluated with the real value data to form a data pair; the position consistency refers to the consistency of positioning data in the data to be evaluated; the feature quantity consistency refers to The characteristic quantity error is smaller than the threshold; determine the matching degree of the data pair matching evaluation scene and the evaluation index, and use the data pair whose matching degree exceeds the threshold as the analysis object; analyze the evaluation index for the analysis object, and obtain the evaluation result. The invention can automatically process and analyze a large amount of automatic driving data, and has the advantages of high efficiency, large amount of data processing and accurate statistical indicators.

The present application provides a preview image processing method, a processing device, a camera device and a readable storage medium. The method is applied to an imaging device, and includes: obtaining a reference preview image collected by the imaging device, the reference preview image including the subject; determining the position information of the shooting background in the reference preview image in the reference preview image; determining The relative moving speed of the shooting subject relative to the camera device; if the relative moving speed is less than the first threshold, when the preview image to be processed subsequently collected by the camera device is acquired, if the preview image to be processed is acquired If the time interval between the image and the acquisition of the reference preview image is less than a first preset time interval, blurring is performed on the image area indicated by the position information in the preview image to be processed. In the present application, the blurring process of the preview image can be realized on the premise of avoiding an excessive data processing amount of the camera device.
