Problems solved by technology

Under the premise of high resolution, in order to achieve a wide viewing angle, it can be realized by horizontally rotating the line array sensor, but because the optical lens is very heavy, the rotation can only be performed at a low speed. This system can only collect static images and cannot collect high frames. rate video
[0004] To sum up, it is difficult for the existing technology to meet the video capture requirements of wide viewing angle and high resolution at the same time

Abstract

The invention provides a video collection device and a collection method using the device, comprising: a line sensor, a grating sensor, a lens and a plane mirror, wherein the line sensor is fixedly connected to the plane mirror and can rotate around the longitudinal axis together, and the lens is positioned at the line sensor. Between the plane mirror and the plane mirror; the line array of the line array sensor passes through the longitudinal axis vertically, the optical axis of the lens coincides with the longitudinal axis, and the normal line at the intersection of the plane mirror and the longitudinal axis is in the same plane as the line array; the grating sensor is used for Sampling signals are sent to the line array sensors at preset intervals, and the line array sensors are used to collect multiple sets of line array data according to the sampling signals. The invention can realize video collection with wide viewing angle and high resolution.

Description

technical field [0001] The invention relates to the technical field of video collection, in particular to a video collection device and a collection method using the device. Background technique [0002] The resolution of the video system ranges from standard definition (720x576) to high definition (1920x1080), from high definition to ultra-high definition (3840x2160), continuously improving the visual experience of the audience. On the video acquisition side, this improvement in resolution mainly depends on the improvement in the resolution of the area array sensor. The photosensitive units on the area array sensor are arranged in a matrix, so it is difficult to improve the resolution. [0003] Corresponding to the area sensor, there is also a line sensor that can achieve high-resolution output. Under the premise of high resolution, in order to achieve a wide viewing angle, it can be achieved by horizontally rotating the line array sensor, but because the optical lens is ...
