Description

Automatic Video and Snap Image Generation System System {Auto Dynamic and Snap Image Generation Equipment System}

With the activation of electronic commerce, more realistic images are needed for catalog production, promotional materials, and other products provided through corporate websites. In addition, when the number of products is large, such as an Internet shopping mall Web site, it takes a lot of time and manpower to make a video for all products. However, rather than providing only flat two-dimensional images so far, in some cases, image information about the product is snapped at various angles and edited to give the effect that the product rotates 360 degrees, or to photograph the product as a video. To show buyers a better sense of presence. As a result, a device for automatically generating image display for merchandise display of an Internet shopping mall-related company is being developed using a digital camera, which is edited through a computer using a USB or a serial communication port and posted on a website. .

As described above, an automatic image generating device using a digital camera uses a USB or serial port, and thus has a disadvantage in that image generation speed is very slow. For example, it takes more than 15 minutes to shoot a 15-sided snapshot of a small or medium-sized product, and then edit and post it on a website. This is a problem that takes a lot of production cost and time for a company such as a large Internet shopping mall that requires the creation of a large amount of product images. The most essential part of the present invention related to video and 360-degree rotating snap image automatic generating device is not using a conventional digital camera, but using a high-definition vision camera used in robots or semiconductor inspection equipment. In addition, in order to acquire image information of a vision camera, a high-speed computing device may be used to obtain a video in MPEG and AVI file formats, and a snap image may be obtained like a conventional device. Since it can acquire 33 frames per second, compared to the existing product, it is possible to generate images at high speed compared to 10 to 15 minutes to acquire 12 snap images. In the device system of the present invention, a controller for driving the movement of the turntable according to a user's setting state communicates with a computer through a serial port using a 16-bit microprocessor.

① Turntable ② Drive motor

③Sensor ⑤Hardware Controller

⑥vision camera

In the hardware configuration of the apparatus as shown in FIG. 1, the turntable ① is a device for raising an object to obtain an image, and the height is adjusted. In addition, it is possible to mount a table of different sizes according to the size of the object. The driving motor ② is a type in which a reduction gear is attached to a DC motor, an AC motor, and a stepping motor. Since the maximum capacity must be relatively large according to the weight of the object, the type and specification of the motor vary according to the maximum load. For example, the stepping motor is applied at 90W or less, the DC motor is applied at 300W or less, and the AC motor is applied at 300W or more. The sensor ③ is applied to control the rotation angle or speed of the turntable ① according to the user definition. The type of sensor ③ is robust to noise and uses an encoder that is excellent in accuracy. The power supply ④ supplies the DC power required for the hardware controller ⑤, the drive motor ②, the sensor ③, and the like. The type of power required is DC 5V, 25V. The hardware controller ⑤ acquires the signal of the sensor ③, controls the drive motor ② by using the obtained information, and exchanges information with the computer ⑦ through serial communication. Vision camera⑥ supports high resolution color and sends video signal in connection with computer⑦. The main computer ⑦ is connected to the hardware controller ⑤ and the vision camera ⑥ to control the operation, and automatically sets the image acquisition method and the number of snapshots according to the user's request. Other equipment not included in FIG. 1 includes lighting devices, screens, tripods, and the like.

In the components of the hardware controller as shown in FIG.
