The present invention relates to a single modular apparatus using a carrier board, and more particularly, to a single modular apparatus using a carrier board for implementing a function of a host CPU and a frame grabber on one board by using a carrier board.

Frame Grabber is a device that converts images from video media such as TV, video, and camera into signals that can be processed by a computer, etc. Also called a video acquisition board. The frame grabber for image acquisition exists as various types of boards according to the PC environment. PCIe (PCI Express), cPCI (Compact PCI) and VME (Versa Module Europa) for industry.

In addition, a vision board including a DSP (Digital Signal Processor), a CPU (Central Processing Unit), and the like functions as a frame grabber board.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

2 is a block diagram of a single modular apparatus using a carrier board according to an embodiment of the present invention.

A single modularization apparatus using a carrier board (hereinafter referred to as a "single modularization apparatus") comprises a carrier board 1 and a host CPU (not shown) 100 and a frame grabber 200 which is integrally implemented on the carrier board 1 and converts an image captured by the camera 50 into a signal that can be processed by the host CPU 100 do.

 The host CPU 100 is modularized and mounted on one carrier board 1 and a frame grabber 200 function is implemented on the carrier board 1. [ That is, the single modular apparatus includes a carrier board 1 on which the host CPU 100 is modularized and loaded to a predetermined standard, and implements the function of the frame grabber 200 on the carrier board 1.

Acquires an image from an imaging device such as a camera 50, and converts the image into a signal that the frame grabber 200 can process by the CPU. That is, the frame grabber 200 integrally implemented on the carrier board 1 acquires an image from the camera 50, processes the signal, and transmits the processed signal to the host CPU 100, which is modularly mounted on the carrier board 1 .

The host CPU 100 modularly mounted on the carrier board 1 processes the data processed by the frame grabber 200 and transmits the processed data to the purpose of the frame grabber 200 or controls the facility or the process according to the result of the determined contents.

All operations are performed by the frame grabber 200 and the host CPU 100 provided in one integrated carrier board 1 and the image data acquisition, data processing, data processing, data-based facility or process Control and the like are performed through internal control on the carrier board 1, so that the data processing speed is improved and the facility can be controlled quickly.

Here, since the host CPU 100 performs processing and processing of image data, a separate CPU for vision is not required. In addition, the host CPU 100 is modularized and physically separated and assembled. However, since the host CPU 100 and the frame grabber 200 are mounted on one carrier board 1, the configuration is maintained by one board. Since the function of the frame grabber 200 and the host CPU 100 are realized by one board, the carrier board 1 is recognized as one module even on a physically configured bus.

The carrier board 1 and the frame grabber 200 can be replaced with the host CPU 100 only by replacing only the host CPU 100 according to the type or specification of the host CPU 100 desired by the user It is possible to keep the existing one.

When the host CPU 100 is modularized and mounted on the carrier board 1, the host CPU 100 is modularized and mounted in the COM Express standard.

COM (Computer-On-Module) can be loaded with all the components required for building a bootable host computer, and these can be defined as modules packaged as ready components. System expansion and customization for each solution is implemented on the carrier board. COM implementation is suitable for a wide variety of embedded applications mechanically, economically, and functionally, and is an alternative when other form factors, such as add-in cards, are not available.

COM Express is a computer-on-module form factor that is highly integrated and miniaturized for use in design applications such as many integrated circuit components. In other words, the goal of COM Express is to achieve a small form factor module specification that meets all the performance areas of the embedded industry.

By using the COM Express module, it is possible to easily manage the shape, size, and function in a specific application, thereby minimizing the design risk. With COM Express, you can continue to support legacy interfaces (such as PCI and AGP) as well as introduce all sorts of LVDS interfaces (PCI Express, Serial ATA, and Serial Digital Video Out).

The COM Express module has a compact basic form factor (95mmX225mm) and an expansion form factor (110mmX155mm). Both form factors are interchangeable because they have the same number of pins and connectors. The expansion form factor has room to spare, so you can double your memory capacity or dual-channel configuration, and use larger processors and chipsets. In addition, since the module height and heat spreader are standardized, it is easy to replace it with another maker's module. COM Express can be designed according to the nature of the embedded application by flexibly selecting two form factors. In addition, there is a small form factor (95mm x 95mm), and an ultra-form factor is being considered along with future revisions of the COM Express specification.

The image picked up by the camera 50 or the like is converted into a processable signal by the frame grabber 200 embodied in the carrier board 1 and then modulated according to a predetermined standard such as COM Express, The host CPU 100 processes the signal converted by the function of the frame grabber 200 to control the movement of the facility. For example, a frame grabber 200 is required for accurate pickup and mounting of a chip in a flip chip mounter process or a chip mounter process, and a host CPU (not shown) 100 controls the movement of equipment such as a chip mounter or a part of a component based on a signal transmitted by the frame grabber 200, thereby controlling the activity of the mounter process.

The frame grabber 200 acquires an image from the imaging device such as the camera 50 and converts the image into a signal that the frame grabber 200 can process by the host CPU 100 And extracts the vision data. And transmits the extracted vision data to the host CPU 100. Vision data is data obtained by converting an image into digital data, and can compress and transmit data to the host CPU 100 so as to facilitate data transfer. The data in the form of a compressed format may have various formats such as Moving Picture Experts Group (MPEG) -1 or MPEG-4, Joint Photographic Experts Group (JPEG), H. 264, and the like.

The host CPU 100 generates control information by applying a vision algorithm to the vision data transmitted from the frame grabber 200. In the case of the conventional vision board 21, there is a CPU that applies the vision algorithm to the vision data. However, since the host CPU 100 and the frame grabber 200 are integrated on a single board, It is preferable to apply it to the vision data. Of course, a separate CPU for application of the vision algorithm may be added to the frame grabber 200 integrally formed on the carrier board 1.

Here, the vision algorithm converts the vision data into an appropriate form to obtain the desired information. For example, when the vision data is obtained from the image captured by the substrate, the image is binarized and labeled to determine and extract the area of the chip mounted on the substrate.

Specifically, in the preprocessing process, a pixel having a low value based on a predetermined threshold value acquires a binarized image represented by white, and a pixel having a high value of black is obtained using a mean value of brightness values of all pixels Or iterative selection, two peak method, or the user can set the threshold value directly.

Then, erosion and dilation operations are performed on the binarized image to remove the noise of the binarized image. That is, the erosion operation expands the background area for the subject area, reduces the size of the subject, and removes or reduces noise components around the subject area. Then, in order to restore the size of the reduced image of the subject, the size of the subject is enlarged and the background is reduced through expansion calculation.

Then, the region of the chip mounted on the substrate is determined and extracted based on the binarized image. At this time, the area of the chip is determined using a labeling operation. That is, a labeling operation is performed to assign different numbers to the regions of the mounted chip, and a region of the chip is determined and extracted by reconstructing the binarized image by attaching different numbers to the regions of the chip.

Based on data obtained by extracting a region of a chip mounted on a substrate by applying a vision algorithm, it is possible to identify a region where the chip is mounted on the substrate, to determine whether or not a chip mounted on the substrate is defective, 100) can perform various activities according to these results.

That is, the host CPU generates control information for performing various activities by applying a vision algorithm to the vision data transmitted from the (200) frame grabber 200. The host CPU 100 controls the external device by giving the control information to the external device connected through the various ports included in the carrier board 1. [
