Method and device for adjusting camera position

Abstract

The method comprises: attaching the video signal cable of the video camera to the image collecting card that is installed in a computer; the video signals outputted from the video camera are inputted into the computer through the image collecting card; the computer reads the image data, and then calculates and displays the gray scale difference between two neighboring pixels and the distance between the optical crosshair and the center of the viewing field; according to the displayed data, adjusting the position of the video camera to let its target surface be on the image surface of the optical system and to let the optical crosshair overlap the center of the viewing field.

Description

Technical field:

[0001] The invention belongs to the technical field of image processing, and relates to a method and a device for adjusting the relative positions of a camera and an optical system in a television tracking control system. Background technique:

[0002] TV tracking control system is generally composed of camera, optical system, tracking measurement electronics system, monitor and other parts. As a video sensor, the camera's installation position and installation accuracy directly affect the imaging quality, and play a key role in the tracking and measurement of the target.

[0003] Current camera installation (eg figure 1 As shown), a collimator 1-1 is added in front of the optical system 1-2, and a resolution board is placed on the image plane of the collimator 1-1. The installer first moves the camera 1-3 back and forth Find the position of the image plane, and at the same time adjust the target plane of cameras 1-3 to be perpendicular to the optical path...
