Embodiment Construction

[0040] The invention will be described in further detail below in conjunction with the accompanying drawings.

[0041] Such as figure 1 with figure 2As shown, the global image acquisition component of the present invention captures the omnidirectional image information of the location where the PT camera is located. Assuming that the PT camera is hoisted at a high place, the global field of view of the PT camera is the lower hemisphere of the coordinate system (the PT camera is installed in other directions, but the global field of view is different, and the method of collecting global field of view images is similar). The PT camera needs to collect the field of view image information of the entire lower hemisphere in the coordinate system. The PT camera collects images along the horizontal and vertical directions according to a certain path to ensure that adjacent images partially overlap.

[0042] In the present invention, while collecting the global visual field image, ...

Abstract

The invention discloses a method and a device for adjusting and controlling the visual field of a PT camera. The method can provide the direct perception of the camera pointing direction to an operator, the direct direction perception is also provided through the panoramic picture, and the PT camera can be quickly positioned in any orientation. The method and the device realize a high efficient man-machine interaction mode, the operator faces to the global view image and directly operates during the positioning process, the visual field can be adjusted, and the operator can conveniently realize the WYSIWYG operating and controlling effect and can well realize the accurate and quick PT positioning in PT camera visual field under the circumstance that the operator is unfamiliar with the mounting position and the control method of the camera.

Description

technical field [0001] The invention relates to a field of view adjustment control method and device of a PT camera, belonging to the technical field of automation control and the field of machine vision. Background technique [0002] At present, cameras with PT (ie Pan&Tilt) functions (ie: PT cameras for short) are widely used in the video surveillance and machine vision industries. The PT function allows the user to flexibly adjust the camera to a certain orientation to achieve field of view adjustment. Compared with fixed-direction cameras, cameras with PT functions can cover a wider field of view under the condition of ensuring clarity, thereby reducing the number of cameras deployed in the project and saving equipment, installation, and operation and maintenance costs. [0003] There are mainly three methods for adjusting and controlling the field of view of the existing PT camera, including: [0004] 1. Joystick control: realize the horizontal and vertical rotation o...
