Device for improving ranging accuracy of binocular camera

Abstract

The invention discloses a device for improving the ranging accuracy of a binocular camera. The device comprises a base, a left rocker arm, a right rocker arm, a left lens, a right lens, a left image sensor, a right image sensor, a left phase distance adjustment device and a right phase distance adjustment device, which can adjust the distance between the lenses and the image sensors in real time according to the rotation angles of the rocker arms, a rocker arm driving device capable of simultaneously adjusting the angles of the two left and right rocker arms, and an angle sensor capable of measuring the rotation angle of the rocker arm driving device; the device can be used in the computer vision ranging or 3D modeling technology, the intersection of the optical axes of the left lens and the right lens can be adjusted to be located in the vicinity of a target object by the present device, thereby minimizing the deviation between the position of the target object in an image obtained inthe image sensor and the real position caused by system errors of a binocular camera ranging device, so that the ranging accuracy of the binocular camera is maximally improved; and meanwhile, the device can locate a clear imaging area of the camera in the vicinity of the intersection of the optical axes of the left lens and the right lens in a running process, the target object is clearly imagedin the image sensor while the ranging is performed on the target object, and the image processing requirements during binocular ranging are met.

Description

technical field [0001] The invention relates to the technical field of camera distance measurement, in particular to a device for improving the distance measurement accuracy of a binocular camera. Background technique [0002] Today, with the increasing rise of artificial intelligence technology, the requirements for artificial intelligence equipment to obtain correct external information are also getting higher and higher; an important means for artificial intelligence equipment to analyze external environmental information is computer vision technology. At present, whether in industry or in personal daily life, there is an increasing demand for computer vision ranging technology. The traditional technical means is to use parallel binocular cameras to identify and analyze the image and obtain the measurement distance. In theory, this technology can achieve accurate distance measurement. However, in engineering practice, due to processing and assembly problems, the image se...

Problems solved by technology

[0009] In addition, ordinary camera imaging generally adopts electronic focusing, and its focusing speed is relatively slow, such as the focusing method of a camera on a mobile phone.

In many practical projects, this focusing method often fails to meet the requirements in terms of speed
