Embodiment Construction

[0046] Clear imaging surface P

[0047] For an image acquisition device, such as a camera, video camera, scanner, etc., it can be known from optical principles that if the physical conditions such as the type and position of optical and electronic components in the image acquisition device are not changed, the distance and range that the camera can clearly image are often fixed. of.

[0048] Such as Figures 1A-1C As shown, the area that can be clearly photographed by the camera 101 is defined as the clear imaging plane P. Generally speaking, the shape of the clear imaging surface P depends on the hardware of the camera 101, especially the shape of the image sensor, Figures 1A-1C The example in FIG. 2 is drawn as a rectangle for illustration only, in fact, the clear imaging surface P can be in any shape. The size of the clear imaging plane P and its distance and angle from the camera 101 are determined by the relative relationship between the lens and the image sensor.

Abstract

The invention discloses an image acquisition system. The image acquisition system comprises a camera and a processor, wherein the camera is used for shooting an image of the surface of a target object; and the processor is used for processing the image of the surface of the target object, shot by the camera when the camera moves relative to the target object to identify the part, coincident with the surface of the target object, of the clear imaging surface of the camera. The invention further provides an image acquisition method. The image acquisition system and method have the beneficial effects that a clear image of the surface of the target object still can be obtained without adjusting the spatial position of a to-be-detected object / camera in advance.

Description

technical field [0001] The invention relates to an image acquisition system and method. Background technique [0002] When collecting images of target objects through image acquisition devices such as cameras and video cameras, it is often necessary to adjust the focal length, aperture and other parameters of the camera or video camera or the relative relationship between the camera, video camera and the target object, such as the direction and distance, according to the optical imaging relationship. Such adjustment steps greatly complicate the acquisition of images of the target object. [0003] Although the current camera has an automatic zoom function, due to the limitation of the depth of field of the camera itself, especially in macro photography, the camera cannot obtain a complete and clear image of the object surface with a certain length through adjustment operations such as automatic zoom. Contents of the invention [0004] An image acquisition system, the image...
