Embodiment 1

[0063] Please refer to figure 2 , Embodiment 1 of the present invention is: a single camera translation system, including a camera 1, a conductor shaft 2, a constant voltage power supply 3, a current collector 4, a pulling device 5 and a host computer 6; the conductor shaft 2 is provided with A slide 21, the slide 21 is slidably arranged on the conductor shaft 2; the camera 1 is arranged on the slide 21, so that the camera 1 is slidably arranged on the slide 21 through the slide 21 On the conductor shaft 2; one end of the conductor shaft 2 is provided with a conductive connection point a, the conductive connection point a is connected to one end of the constant voltage power supply 3 through a wire, and the contact b of the slide plate and the conductor shaft passes through The wire is connected to the other end of the constant voltage power supply 3; the conductive connection point a and the contact b are respectively connected to the current collector 4 through wires; the p...

Embodiment 2

[0071] Please refer to image 3 , Embodiment 2 of the present invention is: a single-camera ranging method, said method is based on the single-camera translation system of Embodiment 1, comprising the following steps:

[0072] S1: The host computer controls the camera to take pictures at the preset initial position on the conductor shaft to obtain the first image, and according to the distance between the initial position and the end of the conductor shaft with the conductive connection point, obtain the corresponding position of the first image first distance. Further, the target to be measured can be photographed, or can be directly photographed without the target to be measured.

[0073] In this embodiment, the preset initial position is one end of the conductor axis where the conductive connection point is set, and at this time, the first distance corresponding to the first image is 0.

[0074] S2: The host computer determines the point to be range-measured in the first ...

Abstract

The invention discloses a single-camera translation system and a single-camera distance measurement method. The method comprises steps of enabling a camera to take a picture at a preset initial position on a conductor shaft, and obtaining a first image and a first distance corresponding to the first image; determining a specified point in the first image; controlling the camera to photograph in the constant-speed translation process of the camera, and recording current data collected by a current collector during photographing to obtain more than one frame of second image and corresponding current data; respectively calculating a first distance corresponding to each second image; tracking the specified point or a tracking point of a previous frame in each second image in sequence accordingto the photographing time to obtain the tracking point in each second image; and randomly selecting two frames of images, and calculating a distance between a to-be-measured target and the camera according to the focal length of the camera, an abscissa value of the specified point or the tracking point in the two frames of images and an absolute value of a difference value of the first distancescorresponding to the two frames of images. The method is advantaged in that ranging cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of ranging, in particular to a single-camera translation system and a single-camera ranging method. Background technique [0002] Computer vision ranging has broad application prospects in robotics, monitoring, and somatosensory games. At present, there are several relatively mature computer vision ranging products on the market, mainly divided into RGB binocular ranging, infrared structured light ranging and infrared TOF ranging. Among them, RGB ranging has the lowest cost, requiring only two RGB cameras; structured light ranging and TOF ranging require infrared transmitters and infrared receivers, the former uses the triangular ranging principle (same as RGB binocular ranging), and the latter They use the time-of-flight of light to calculate object distances. [0003] Among them, for the principle of binocular ranging, such as figure 1 As shown, Q is a certain point on the object to be measured, O R wi...
