Detailed Description
According to one or more embodiments, as shown in fig. 1 and 2. The composition of an industrial camera or an industrial video camera comprises a lens, 2 image sensors, a spectroscope and a macro motor. The lens is used for image imaging. The 2 image sensors are the first image sensor and the second image sensor. The spectroscope is arranged behind the lens, when light penetrates through the lens, the light enters the spectroscope, one part of the light is reflected by the spectroscope and then projected to the first image sensor, and the other part of the light is refracted by the spectroscope and then projected to the second image sensor. The micro-distance motor is used for driving the image sensor and adjusting the distance between the image sensor and the spectroscope.
The image or video data output from the first image sensor and the second image sensor needs to be subjected to fusion processing by the image processor to obtain an image or video with a large depth of field with respect to the object to be photographed.
The spectroscope divides the light after the lens imaging into 2 paths, and the light is supplied to the image sensor for receiving. The 2 sensors are placed at positions corresponding to the working distances u- Δ u from the range of the back intercept v-v + Δ v, respectively, to achieve a total depth of field Δ u. The working distance here means an optical path distance from the front surface of the lens to the surface of the subject. The back intercept refers to the distance of the optical path from the back surface of the lens to the surface of the image sensor.
In another embodiment, as shown in fig. 3, a beam splitter is used to split m optical paths and project the optical paths to m corresponding image sensors, the image sensors are placed at equal distances, and the optical path distance from the surface of each image sensor to the rear surface of the lens is different by v, that is, Δ v of the image sensor is (m-1) × v. The image sensors 1-m receive the optical signals from the 1 st to m th paths respectively and process the optical signals through the processing unit, and the control module is used for generating control signals for controlling the image sensors, the image processing modules 1-m and the image processor to perform fusion processing, wherein the control signals comprise unified homologous synchronous clocks used by all the units and synchronous signals of frames and lines used by all the units. The image processor synthesizes images or videos output by the processing units 1-m of the image sensor into a large-depth-of-field ultrahigh-definition video sequence under the control of a control module clock and a synchronous signal.
In accordance with one or more embodiments, as shown in fig. 4, a microscope includes:
the microscope observation lens assembly is used for observing a sample; 2 image sensors, namely a first image sensor and a second image sensor; the spectroscope is arranged behind the microscope observation lens assembly, when light penetrates through the microscope observation lens assembly, the light enters the spectroscope, one part of the light is reflected by the spectroscope and then projected to the first image sensor, and the other part of the light is refracted by the spectroscope and then projected to the second image sensor; the image processor performs fusion processing on image data acquired from the first image sensor and the second image sensor; and the micro-distance motor is used for driving the image sensor and adjusting the distance between the image sensor and the spectroscope or the spectroscope component.
According to one or more embodiments, as shown in fig. 5, a PCB detection system employs an industrial camera or an industrial video camera as mentioned in the above embodiments, and a lens of the industrial camera or the video camera faces a PCB to be detected, so as to detect the assembly quality of electronic components loaded on the PCB to be detected.
