Description

Technical Field

[0001] The present invention relates to the technical field of camera focusing equipment, and in particular to a fully automatic testing device for an ultra-wide-angle camera. Background Art

[0002] The past decade has been the golden period for the development of smart cars, and the car camera market has grown rapidly along with the growth of terminals. Cameras have also been upgraded from original pixels to later functions; fisheye cameras are panoramic cameras that can independently achieve large-scale, no-dead-angle monitoring. The current mainstream panoramic cameras can achieve 360° and 180° monitoring effects by hanging and wall mounting, respectively, and some cameras with only 120° to 130° field of view can also be called panoramic fisheye cameras because they can meet customers' demands for monitoring a relatively open area. The image captured by the camera is processed by the image processing of the main chip inside the camera, and the spherical image is corrected and the image is expanded to convert it into a normal plane view suitable for the human eye.

[0003] With the breakthrough of ultra-high-resolution sensor technology and the rapid increase in the processing speed of signal processors, the application of ultra-high-resolution cameras in various fields is becoming increasingly popular. Considering the convenience of size, installation, maintenance, and use, fisheye lenses with ultra-wide field of view have been widely used in the fields of automobiles, surveillance, etc. Fisheye lenses are a special type of lens among ultra-wide-angle lenses. Compared with ordinary lenses, fisheye lenses have a wider field of view, so they can obtain more image information. The images recorded by fisheye lenses are all distorted images of scenes within a wide field of view. Therefore, the distortion phenomenon needs to be corrected during the production process of fisheye lenses, and the correction of fisheye lenses requires black / white field testing of the resolution of fisheye lenses.

Each first elastic member 236 is sleeved on a step screw, and the upper end of the first elastic member 236 abuts on the step screw, and the lower end abuts on the top holding plate 233.

[0061] When the clamping jaw 231 contacts the lens, if the clamping position of the lens and the clamping jaw 231 is not concentric, the clamping jaw 231 will automatically align itself under the drive of the X-aligning sliding assembly 244 and the Y-aligning sliding assembly 246, and the second elastic member 245 and the third elastic member 247 arranged opposite to each other play a role in stabilizing the first aligning disk 241, the second aligning disk 242, and the third aligning disk 243.
