The invention discloses a vehicle positioning method based on road surface image feature matching: determining the geographical coordinates of the initial position of the vehicle; taking real-time pictures of the road surface images during the driving process of the vehicle; sequentially performing uniform light processing on the currently photographed two consecutive frames of road surface images; real-time Match the two consecutive frames of road surface images after uniform light processing to obtain the matching point pairs of the two consecutive frames of road surface images; perform vehicle positioning according to the obtained matching point pairs; determine whether the current two frames of images are the last two frames, if so, then end, otherwise repeat the above steps. This method only needs to collect road images in real time while the vehicle is running, and match two consecutive frames of road images to realize autonomous vehicle positioning. The time-consuming and labor-intensive link of full street view, so save time and effort.

The invention provides an ultrashort pulse time overlap degree measurement device and a method in a CARS microscopic imaging system. The ultrashort pulse time overlap degree measurement device in theCARS microscopic imaging system comprises a femtosecond laser (1), a Stokes light pulse optical path, a pump light pulse optical path, a spectrum analyzer (12), a focusing objective lens (15), a three-dimensional electronic control object stage (16), a collection objective lens (17), a short pass filter (18) and a signal detection and data processing system ( 19). The ultrashort pulse time overlapdegree measurement method in the CARS microscopic imaging system comprises the following steps: calculating the relative time delay, namely the same path delay between the residual pump light pulse and a light soliton used as the Stokes light; according to the interference spectrum oscillation intensity of the residual pump light pulse and the pump light pulse, determining the time delay of the adjustable space optical time delay line, namely the asynchronous time delay, required when the residual pump light pulse and the pump light pulse overlap; and estimating the time overlap degree of ultrashort pulses in the CARS microscopic imaging system when the adjustable space optical time delay line is adjusted according to the same path delay and the asynchronous time delay. According to the ultrashort pulse time overlap degree measurement device and method in the CARS microscopic imaging system, closed-loop feedback control of ultrashort pulse time overlap in the CARS microscopic imagingsystem is facilitated, and the measurement efficiency is improved.

The invention discloses an automatic filter realization method, storage medium, equipment and system, and relates to the field of photographing beauty. The method includes acquiring multiple images as training samples and training the neural network model, and each image contains a A marker used to mark the scene; intercept the live broadcast picture as the image to be detected, use the trained neural network model to detect the content contained in the image to be detected; when it is detected that the image to be detected contains markers, call out the The filter effect of the scene corresponding to the marker is used as the filter effect of the current live broadcast; among them, the markers include solid-color walls, billboards and sky: when it is detected that the marker in the image to be detected is a solid-color wall, the white filter is used as the current live broadcast filter effects. By judging the live broadcast scene where the current host is located, the present invention automatically calls out the filter special effect of the corresponding scene as the filter special effect of the current live broadcast.
