Problems solved by technology

Because whether it is high-resolution mode or high-speed mode, the total amount of data obtained per unit time is the same, and the price of this type of high-performance professional camera is also very expensive, generally the unit price is more than 500,000 yuan

Embodiment Construction

[0008] The structural principle, working process and parameter setting of the present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0009] The technical structure of the ultra-high-speed imaging device is as follows: the image of the object to be photographed passes through a plurality of beam splitters 1a, 1b, 1c, 1d..., and enters each corresponding camera 2a, 2b, 2c, 2d... respectively. The timing controller 3 provides a trigger signal for each camera, so that the cameras take pictures sequentially according to the set time interval. Each camera only takes one image at a time, and the images obtained by each camera are transmitted to the image memory 4 in turn.

[0010] Selection and setting of device parameters in this embodiment: to achieve 2048×2048 pixels, 10 9 The shooting speed of fps acquires 4 consecutive images. Choose 4 ordinary cameras with 4 million pixels, and set the time interval ...

Abstract

The invention discloses an ultra-high-speed camera shooting device. The technical scheme is that images of objects to be shot is subjected to light splitting of multiple spectroscopes and are respectively fed into corresponding cameras, time schedule controllers provide a trigger signal is provided for each camera to enable the cameras to sequentially perform shooting according to set time intervals. Each camera can only shoot one image each time, and the image obtained by each camera each time is transmitted to an image memorizer. Due to the fact that a mode that multiple cameras perform shooting sequentially is adopted, the limitation of data transmission speed to the image resolution and shooting frequency is solved, and accordingly continuous 1015fps ultra-high-speed shooting at ten-million pixel resolution is achieved. Therefore, the cameras and the time schedule controllers are selected as required, the manufacture cost can be reduced from 5 ten thousands to 10 ten thousands yuan, and the ultra-high-speed camera shooting device is low in cost and ultra-high in resolution.

Description

technical field [0001] The invention belongs to high-speed camera technology, in particular to a camera sequence device for ultra-high-speed continuous shooting. technical background [0002] As we all know, high-speed camera technology has a wide range of uses in various industries, especially with the development of science and technology, the continuous shooting function of cameras is becoming more and more important. High-speed and continuous photography can record the image change process of the subject in a very short time. Existing high-end high-speed cameras can achieve 10,000 shots per second (10 4 fps); or at a resolution of 100×100 pixels, a million shots per second (10 6 fps), it can be seen that high resolution and high speed cannot be achieved at the same time. The technical reason is that the transmission speed of the camera data is limited. Because the total amount of data obtained per unit time is the same whether it is a high-resolution mode or a high-s...
