Embodiment 1

[0035] Embodiment one, adopt cloud height measurement method of the present invention to have following steps:

[0036] Step 1 see figure 1 As shown: the two image collectors are set at a certain distance apart, so that image collector 1 and image collector 2 can capture the distance of the same area of ​​the cloud, and obtain the baseline BC, B is the focus of image collector 1, and C is the image collector 2 focal points, the two image collector lenses are perpendicular to the sky, and the long axis or short axis of the imaging plane of the image collector is parallel to the baseline;

[0037] Step 2: The image collector 1 and the image collector 2 take pictures of the same area of ​​the cloud at the same time, and obtain photo P1 and photo P2 respectively;

[0038] Step 3 see figure 2 Shown: Assuming that there is a point A at the cloud base in the common shooting area of ​​image collector 1 and image collector 2, find point A in the photo P1 and photo P2 respectively, w...

Embodiment 2

[0048] Embodiment 2: Different from Embodiment 1, the optical axes of the above two image collector lenses can also be arranged horizontally and parallel, and the major axis or minor axis of the imaging plane of the image collector is parallel to the baseline.

Embodiment 3

[0049] Embodiment 3: Different from Embodiment 1, the imaging planes of the above two image acquisition devices can also be perpendicular to a plane at the same time, and the optical axes of the two lenses form a certain angle of intersection.

Abstract

A cloud height automatic observation process and a device. The device includes an image collector, in which two image collectors form a collecting unit; a sampling controller emitting the cloud image sampling command to two image collectors; an image transmission device respectively connected with two image collector for transmitting cloud picture collected by the image collector to an image processing and sampling control device and transmitting the command from image processing and sampling control device to the cloud picture collecting unit; an image processor connected with the image transmitting device for processing image and automatically measuring the height and the horizontal position of the cloud. The device has simple structure, lower cost and finishes the cloud height measuring automatically and is applied in the fields such as aviation, aerospace and weather.

Description

technical field [0001] The invention relates to a cloud height measuring method and a cloud height measuring device. Background technique [0002] Cloud height is the vertical distance from the cloud base to the ground. The measurement of cloud height is of great significance to the field of aerospace, and it is an important reference data for spacecraft launch. Traditional cloud height measurement devices include cloud curtain lamps, infrared cloud measuring instruments, laser cloud measuring instruments, etc. Among them, the cloud curtain lamp can only be used to measure the cloud height of stratiform clouds at night, which has great limitations. The advantage of the laser cloud meter is high accuracy, fast and convenient to use, but the disadvantage is that it is expensive and can only measure the cloud height of a single point in the sky. The method of using infrared to measure cloud height is to use infrared measuring device to measure atmospheric infrared radiation....
