Method for achieving high-speed camera shooting

Abstract

The invention discloses a method for achieving high-speed camera shooting. The method includes the first step of enabling a photographed object to do linear motion on a shooting plane relative to an area-array video camera, wherein the motion direction of the photographed object is perpendicular to the line direction of a pixel array of the area-array video camera and is parallel to the column direction of the pixel array, the second step of reading line images obtained by each line of pixels in sequence, and the third step of restoring the line images through an image restoring algorithm of a linear-array video camera to obtain images, wherein the line frequency is P in the restoring process, the scanning time interval between two adjacent lines of pixels is recorded to be F, the distance between two adjacent lines of pixels is m, the working distance is H in the shooting process, the focal distance is h, the relative movement distance between the area-array video camera and the object within the time F is L, and the distance that m mapped on the photographed object is M=H*m / h and P=L / (F*L-F*M). By the adoption of the method, the shooting effect of the high-speed linear-array video camera is achieved through a common area-array camera, and cost is effectively reduced. The method is applicable to the fields of size measurement, size detection and the like in industry.

Description

technical field [0001] The invention relates to the field of image generation and restoration, in particular to a method for realizing high-speed imaging by means of an ordinary area array camera. Background technique [0002] High-speed cameras are widely used in many fields such as industrial control, aircraft control, and traffic monitoring. But the price of high-speed cameras is many times higher than ordinary cameras. Moreover, there are very few companies in the world that can produce high-speed cameras. [0003] High-speed cameras are divided into two types: line array and area array. Line array is generally used to shoot objects moving in a straight line, while area array is more suitable for shooting objects with chaotic motion. In principle, area array cameras can also achieve high-speed line The function of array camera is restored to the effect of area array camera under the control of software algorithm. [0004] If we can achieve the shooting effect of high-...
