Embodiment Construction

[0046] The present invention will be further described below in conjunction with the accompanying drawings.

[0047] like Figure 1-2 As shown, the three-dimensional reconstruction device of the transmission housing with binocular stereo vision of the present invention includes two cameras 1, a turntable 3 and two lifting platforms 5, the turntable 3 is horizontally arranged, and the bottom of the turntable 3 is installed on the output of the motor 2 On the axis, the motor 2 can drive the turntable 3 to rotate in the horizontal plane. The two lifting platforms 5 are symmetrically installed on the turntable 3, and the lifting platform 5 is installed on the turntable 3 by the hydraulic cylinder 4 (electric push rod can also be used), which can drive the lifting platform 5 to lift. Each of the lifting platforms 5 is provided with an overturn clamping device. The flip clamping device includes a clamping hydraulic cylinder 6, a motor support 7, a motor 71 and a hand claw 8; the c...

Abstract

The invention discloses a transmission shell three-dimensional reconstruction device and method based on binocular stereoscopic vision. The device comprises two cameras, a rotary table and two liftingtables. The rotary table is horizontally arranged, and the rotary table can rotate around a vertical center line. The two lifting tables are symmetrically mounted on the rotary table. Each lifting platform is provided with a turnover clamping device. Each turnover clamping device comprises a clamping hydraulic cylinder, a motor bracket, a motor and a paw. The two turnover clamping devices can clamp a transmission shell, and the camera lens faces the position between the two claws. The invention is simple in structure and convenient to operate. The two cameras are fixed to the special supportin the structural form of the intersecting optical axis for shooting, efficient non-contact measurement is completed, the problem that secondary errors occur in contact measurement is effectively solved, and the detection efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of transmission housing detection, and in particular relates to a three-dimensional reconstruction device and method for a transmission housing based on binocular stereo vision. Background technique [0002] In recent years, the annual production and sales of automobiles in my country have increased year by year with a certain growth rate. The prosperity of the automobile industry has brought great opportunities and challenges to upstream auto parts companies. Among them, the transmission housing is an important part of the car. It installs the transmission mechanism, the shifting device and some operating mechanisms together, and also plays the role of storing lubricating oil. Therefore, the processing quality of the product is very important to the performance of the car. influences. At present, there is a lack of an efficient and accurate detection method in domestic actual production, and most of them u...
