Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings.

[0036] Such as Figure 1-7 , a variable baseline binocular visual inertial odometer, comprising a housing 3, a support plate 30, a control panel 31, and a switch 36, wherein:

[0037] The housing 3 is a cuboid with a cavity inside, which includes a front panel 1 and an upper panel 2. On the front panel 1 of the housing 3, there are elongated left windows 39 and right windows 40, and the left window 39 and the right window Left camera 4 and right camera 5 are respectively placed in 40, and left camera 4 is installed on the left base 6, and left base 6 is installed on the left rack 16, and right camera 5 is installed on the right base 7, and right base The seat 7 is installed on the right rack 17; the left rack 16 is engaged with the fourth gear 15 and the sixth gear 19, and the right rack 17 is engaged with the third gear 14 and the fifth gear 18;

[0038]The support ...

Abstract

The invention discloses a variational baseline binocular vision inertia speedometer and a method thereof. The speedometer comprises a shell, a supporting plate, a control plate and a switch, wherein a left window and a right window are formed in a front plate of the shell; a left camera and a right camera are respectively placed in the left window and the right window; the left camera is mounted on a left base; the left base is mounted on a left rack; the right camera is mounted on a right base; the right base is mounted on the right rack; the supporting plate is mounted in the shell; a driving motor and a balancing weight are mounted on the supporting plate; a first gear is mounted on the driving motor; a second gear is mounted on the balancing weight; the first gear is meshed with the second gear; the first gear is meshed with a third gear; the second gear is meshed with a fourth gear; the control plate is mounted in the shell; an IMU (inertia measurement unit) and an STM32 processor are mounted on the control plate; the switch is mounted on the shell and is connected with the control plate by a circuit. In the speedometer, a variational baseline binocular camera can be effectively combined with the IMU.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a baseline-changing binocular visual-inertial odometer and a method thereof. Background technique [0002] Vision-based Simultaneous Localization and Mapping (SLAM) is gradually being used in robotics such as driverless cars, drones, and sweeping robots, as well as in augmented reality and virtual reality. Able to locate objects and build a 3D environment map in an unknown environment. [0003] However, in the field of computer vision, simply using the camera for initialization has scale problems, and at the same time, problems such as scale drift and low positioning accuracy are prone to occur during operation. Nowadays, the baseline between the two cameras of the binocular camera is fixed, and the camera uses the triangulation method to calculate the position of the object in the environment based on the image information of the two cameras. However, binocular cameras with fixed ba...
