Servo EPC System Web Guide System With CCD Sensor

HCCD inear array sensor is a color camera can track the edge of the material, contrast edges, lines, patterns and the like. Due to the track The materials vary, we need to tell the sensor to track the target, which requires calibration target to track.

1.Detection algorithm

 HCCD sensors support a variety of different algorithms, namely: color, monochrome, monochrome binarization, luminous flux  integration, side light. The monochrome algorithm has the highest processing speed and is suitable for extremely low contrast  edges or simple lines, especially for the heel of the transparent material. The color algorithm uses white light to illuminate the  material and captures a color image. This algorithm shows that it is suitable for the correction of complex patterns (rich colors).

2.Automatic exposure

After enabling (checking) the automatic exposure of the exposure mode, the HCCD sensor can automatically set the  appropriate exposure time and lSO value according to the image color and brightness of the material to make the image clear.

3.Manual exposure

After enabling (checking) the manual exposure of the exposure mode, the user can adjust the brightness and contrast  of the image until a satisfactory image is seen.

4.High contrast option

In auto exposure mode, when the high contrast is enabled (checked), the image becomes brighter.

5.Global metering / center metering

In auto exposure mode, global metering and center metering can be selected. Global metering: Metering the entire image, automatically adjusting the optimal exposure time, contrast and brightness. Center metering: After selecting the center metering mode, a pair of brackets [] will be displayed in the image display area.  The sensor will meter the image in the [] area to automatically adjust the optimal brightness and contrast. Center metering  is more suitable for tracking extremely low contrast edges. Move the edge or line to be tracked to the metering area in [] and let the sensor calculate the image with the highest contrast.

Press the <Calibration Target> button to enter the calibration procedure. The HCCD sensor will emit two laser lines with different angles to assist the focus. As shown in the figure below, when the two laser lines coincide, the distance between the HCCD sensor and the material is the optimal distance. The focus is just on the surface of the material. In addition, the appropriate illumination angle needs to be selected according  to different material properties. It is generally divided into two cases:
