2.Mechanical Interface 2.3. Optical Interface Figure2- 5 Optical interface Mercury USB cameras are equipped with C-mount lens adapters. The distance between the installation datum of lens and sensor photosensitive surface is 17.526 mm (in the air). After the filter/ transparent glass is installed, the distance between the installation datum and the filter/ transparent glass is 10.8mm, As shown in Figure2- 5, the lens can intrude into the camera body a maximum of 10.8mm.
2.Mechanical Interface 2.5. Environment Requirement Housing temperature during operation:0° C ~ 45° C,Humidity during operation:10% ~ 80% (relative , non-condensing). To avoid collecting dust on the optical filter, always keep the plastic cap on cameras when no lens is mounted. Make sure that cameras are transported in the original factory packages.
3. Installation and Use 3.1. Setup Guide The installation of Daheng Imaging Camera Software Suite is very simple, but you have to take attention to the following matters. The path of installation can only be ASCII characters; otherwise you will not start the applications successfully.
4.Image Acquisition Control 4. Image Acquisition Control 4.1. Exposure 4.1.1. Exposure Mode Mercury series camera has two exposure modes: CCD cameras: Global shutter; CMOS cameras: the MER-040-60Ux camera is global shutter, and the others are electronic rolling shutter; Global shutter means that all the lines in the sensor are exposed at the same time. The high frame rate of up to 60fps allows the Mer-040-60Ux camera to be more suitable for moving objects and not to produce shadows.
4.Image Acquisition Control 4.1.3. Auto Exposure The MER series camera is designed for the industrial applications, designed for automatic exposure control, which can be adapted to different light variations without human intervention. The user can choose the operating environment according to the surrounding environment, and sets the Maximum & Minimum values of the adjustment, and ExpectedGrayValue, which can be automatically adjusted.
4.Image Acquisition Control Figure 4- 1 VGA Gain 4.4.2. Digital Gain The camera also provides a hardware digital gain when outputting 8bit images. Table4- 6 Digital Gain Mode Hardware digital Gain ADC Level 0: Original brightness × 1 MER-500-7Ux ADC Level 1: Original brightness ÷ 2 MER-030-120Ux ADC Level 2: Original brightness ÷...
4.Image Acquisition Control 4.5. Black Level The MER series USB interface camera is all with black level adjustable function. When the user needs to adjust the black level manually, he should disable the automatic black level calibration function, otherwise the camera may adjust it automatically. For CMOS cameras, if the automatic black level calibration function is disabled, some problems will appear in some situations, especially when using the Mono cameras, some fine grid will appear in the image.
4.Image Acquisition Control Figure 4- 2 Camera input circuit 4.8.2. Output Port The MER series camera has one channel output signal, which is connected into the camera by the Hirose of the camera. And the output signal is opto-isolated. The voltage range of the VCC must between 5VDC -24VDC.
4.Image Acquisition Control 4.8.3. Connection Method of Cables The MERCURY USB interface cameras have two types of trigger signals, one is positive voltage drive signal and the other is negative voltage drive signal. Both the High and the Low which are described in the software interface function and the demo, are based on positive voltage drive.
5.FAQ 5. FAQ General Question Answer Lower the acquisition speed; Increase the horizontal blanking length; The cameras often stop capturing Check the cable, Host and working environment; while working, but returned to normal after executing the start Recommend to use the USB port which is on the capture command.
