Abstract: Embodiments of a method and device for controlling image capturing and a system for acquiring an image of a chassis of a vehicle are provided, which relate to image capturing technology and can eliminate deformation of images occurred due to stretch or compression in image capturing. The system includes a speed measuring module, a control module, and a line scan camera. The speed measuring module measures the speed of the vehicle and transmits the measured speed of the vehicle to the control module. The control module determines line frequency for image capturing according to the speed of the vehicle, and controls the line scan camera to perform image capturing on the chassis of the vehicle with the line frequency.

Abstract: A 3D information detection device includes a DLP projector (100), a camera (200), a controller (300) and an image processing module (400). The DLP projector (100) is configured for projecting encoded structured light to an object, the camera (200) is configured for acquiring an image of the object to which the structured light has been projected, the image processing module (400) is connected to the camera (200) and is configured for processing the image to obtain 3D information about the object, the controller (300) is connected to both the DLP projector (100) and the camera (200) and controls the operations thereof. The above device can solve the problem that 3D information about an object cannot be directly obtained at present.

Abstract: The present application discloses a lens, camera, package inspection system and image processing method. The lens comprises an optical lens and a photosensitive chip, and further comprises an optical filter comprising a first filter portion and a second filter portion and disposed between the optical lens and the photosensitive chip, wherein a first object point is imaged on the photosensitive chip through the optical lens and the first filter portion, and a second object point is imaged on the photosensitive chip through the optical lens and the second filter portion, the first filter portion having a thickness greater than that of the second filter portion. The technical problem of a lens in relevant art having a relatively small DOF is solved by the present application.

Abstract: Disclosed is a dome camera, including a spherical surface part (A) positioned in the center and an edge part (B) connected thereto, wherein an internal surface (3) and an external surface (4) of the edge part (B) are revolving surfaces, and a revolution axis thereof is parallel to that of the spherical surface part (A); the internal surface (3) is in a direction away from the spherical surface part (A) from a joint with the spherical surface part (A), with a monotonically increasing revolution radius; and focal power in both a meridian direction and a sagittal direction of the edge part (B) is the same as that of the spherical surface part (A).
