Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] The purpose of the present invention is to provide an automatic data collection device that can control each main factor in the part photo collection process and collect high-quality data sets for training part recognition algorithms. By fixing the parts on the liftable tray and cooperating with the light source with adjustable angle, the control requirements of different light intensity, distance and angle in the process of part photo collection are completed. A set of guide rail mechanism arranged on the liftable pallet provides the camera moving in the axial direction and height direction of the pallet and the rotation mechanism of the camera mounting seat, which realizes the control of different angles and distances of the camera relative to the workpiece. The device can precisely control the light intensity, light angle, light distance, came...

Abstract

The invention discloses a part identification data set acquisition device which comprises a lifting type frame structure, a light source control mechanism, a part tray and a camera control assembly. The lifting type frame structure is a cuboid frame. The light source control mechanism is installed at the top of the lifting type frame structure and provides illumination for parts. The part tray isinstalled on the lower portion in the lifting type frame structure and used for containing parts. The camera control assembly is installed above the part tray and used for fixing the camera and changing the relative position of the camera and the part. The acquisition device can simultaneously control one or more of five parameters including illumination intensity, illumination angle, illuminationdistance, camera angle and camera distance. Variable control is strict, angle, strength and distance change gradients are uniform and reasonable, the data set quality is high, the convergence rate ofthe part recognition algorithm training process can be increased, and the algorithm recognition capacity is improved.

Description

technical field [0001] The invention belongs to the technical field of image acquisition, and in particular relates to a part data set acquisition device. Background technique [0002] With the development of deep learning technology, this technology is more and more widely used in parts recognition and pose estimation in the automated production process. However, deep learning to recognize parts requires a large number of parts photos in different states to form a training data set to complete the training of the recognition algorithm. Traditional dataset collection methods mostly rely on manual completion, and it is difficult to maintain control of variables such as camera position, camera angle, and light source position during the photo collection process. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides a part recognition data set acquisition device, including a lifting frame structure, a light ...
