Variable-focus monocular and binocular vision sensing device

Abstract

The invention provides a variable-focus monocular and binocular vision sensing device comprising a mirror image type optical system, a high-precision bearing holder, an image acquisition system, a digital information processing device and other parts. The variable-focus monocular and binocular vision sensing device can guarantee that a variable-focus image sensor (a CCD (Charge Coupled Device) or an analog video camera) mounted on the high-precision bearing holder can be accurately located at a certain required monocular vision preset station, and can automatically regulate the focus to the required value so as to perform monocular vision measurement or guidance work; the variable-focus monocular and binocular vision sensing device also can accurately locate the image sensor at the unique determined binocular vision preset station, and can automatically regulate focus to the required value, and thus, the image sensor and the mirror image type optical system jointly form a binocular vision sensing system, and sequentially, the function of binocular vision guidance or measurement is realized; and moreover, the variable-focus monocular and binocular vision sensing device can realize automatic switching between a monocular vision station and a binocular vision station through programming of the digital information processing device according to the task requirements, so as to realize the functions such as monocular and binocular vision measurement, guidance or obstacle avoidance.

Description

technical field [0001] A variable-focus single and binocular vision sensing device designed by the present invention belongs to the technical field of machine vision applications, and specifically relates to timely and flexible realization of monocular vision measurement function and binocular vision measurement under different measurement environments and precision requirements Functional visual sensing device. Background technique [0002] With the maturity of computer vision and image processing technology, camera vision sensing and measurement technology is gradually developing in the direction of automatic and fast non-contact, and has become an important development direction in the field of machine vision application technology. Currently commonly used visual sensing and computer vision measurement technologies mainly include the following two types: [0003] I) Monocular vision measurement and guidance technology: This technology is to measure the spatial position o...

However, the symmetrical design makes the measurement range small and the application is not flexible enough

[0005] To sum up, due to the limitations of the system structure and measurement principle of the existing visual measurement devices, a single visual measurement device can generally only be applied to a specific measurement occasion, either the application of a monocular vision system or a binocular vision system. So far, there is no visual sensing measurement device that can realize the functions of monocular vision measurement and binocular vision measurement in a timely and flexible manner.
