X: coordinate that identifies the horizontal position of the first locator point.
  • Page 101 Instruction Manual SCS1 Series 6.7.6. Intersection locator Description: calculates the intersection point between two lines. The locator has two operators that supply the data necessary to calculate the intersection. The operators can be selected amongst the tools used in the previous operating steps.
  • Page 102 SCS1 Series Instruction Manual 6.8. Controls Control tools are used to determine the inspection specifications. The control tools supply a numeric result as well as a status, necessary for the successive operating phases. 6.8.1. Edge Description: similar to the Edge locator, as it tracks an edge position. Refer to Edge locator for further details.

  • Page 105 Instruction Manual SCS1 Series Constraints: the Edge locator is characterised by a specific ROI. The elaboration can be limited to a certain ROI part: Beginning: first elaboration starting point. End: first elaboration ending point. Note: the threshold refers to the highest value that remains the entire Edge locator area.
  • Page 106 SCS1 Series Instruction Manual 6.8.5. Internal caliper Description: the internal caliper measures distances between two edges. The tools is represented graphically by a line and carries-out measurements with the following criteria: starting from the middle point of the line, it tracks an edge in both directions (towards end).
  • Page 107 Instruction Manual SCS1 Series Direction: determines the direction of the elaboration: “from start to end”: elaboration starts from the first end and continues towards the arrow; “from end to start”: elaboration starts from the arrow and continues towards the first end (opposite to the arrow’s direction).
  • Page 108 SCS1 Series Instruction Manual 6.8.7. Blob count Description: tool used for blob counting inside a specific area. The tool is represented graphically by a rectangle that delimits the ROI where the blobs are tracked. Setting the number of expected blobs (parameter “Number of object”) the OK/failure status is therefore obtained.
  • Page 109 Instruction Manual SCS1 Series Choosing again Manual threshold selection Automatic threshold selection Threshold/register association Moreover, as already explained in the “Regist” section, the threshold is a parameter and so it can be associated to a sensor register. The threshold can be thus recalled and modified using the device integrated interface.
  • Page 110 SCS1 Series Instruction Manual Blobs are tracked on binary images and consequently tone information is lost. Everything is either black or white.This information is recovered, calculating the medium grey blob level on the original greyscale image. Maximum and minimum grey level values can be specified in order to distinguish objects with the same shape but with a different colour.
  • Page 111 Instruction Manual SCS1 Series 6.8.8. Contour match Description: compares a template with a target-object according to the contour characteristics. The Contour match is represented graphically by a rectangle that identifies a ROI where to track the target-object. The target-object is tracked through a Blob analysis aimed at finding the largest inside the ROI (similar to Blob locator).

    The SCS1 smart camera presents a 100 Mb/s communication port that can be used for HOST PC and configuration interface communication. Please contact DATASENSOR for further technical specifications. 7.2. Serial protocols and digital inputs The SCS1 series offers three models presenting different communication protocols and supplementary digital inputs: 1. RS232 serial protocol 2. RS485 serial protocol 3.
  • Page 124 SCS1 Series Instruction Manual SCS1 with RS485 serial protocol: pin 1 of the 8-pole M12 connector dedicated to the transmission of data from the SCS1 to PC and pin 6 to the data receipt. The standard protocol implemented on the PC is RS232. If the SCS1 smart camera has to be used with the RS485 serial protocol, a RS232/RS485 serial adapter has to be used to guarantee interfacing with the sensor’s receiver.
  • Page 125 Instruction Manual SCS1 Series SCS1 with supplementary digital inputs: pin 1 and 6 are used as supplementary digital inputs able to select one of the four available inspections that can be saved on the sensor. The figure represents one of the four possible input configurations: 24 V 7.4.

  • Page 147: Appendix A: Image Elaboration Techniques

    Instruction Manual SCS1 Series 12. APPENDIX A: IMAGE ELABORATION TECHNIQUES 12.1. General concepts: digital image What is a digital image? A digital image is simply a matrix of numbers. Each matrix element is called picture’s element or pixel. ( e.g.: SCS1 resolution is 640x480 and consequently the image is composed of 640 columns and 480 lines, forming a total of more than 300000 pixels).
  • Page 148 SCS1 Series Instruction Manual 12.3. Binarization Operation that converts a greyscale image into a monochrome one. An image formed by black and white pixels is obtained. Only the most essential information of the initial image is maintained. In most cases, pixels belonging to the same object have very similar grey values and after the binarization operation are gathered together in a white or black area.
  • Page 149 Instruction Manual SCS1 Series Use lenses with variable slots: the slot is a hole that allows light passage. The light passes through the lens and hits the surface and acquires the image. Larger the hole, the more light passes and the minor image depth. The focussing of an object with a variable lens distance may result to be difficult.
  • Page 150 SCS1 Series Instruction Manual The advantages offered by the Blob analysis consist in high elaboration speed and possibility of tolerating and measuring object orientation and dimension variations. While the constraints consist mainly in the difficulty of distinguishing objects from backgrounds with low contrasts, objects in touch with each other or overlapped objects as well as the difficulty of recognising similar objects.
  • Page 151 Instruction Manual SCS1 Series Dividing per three these values and placing them on one single line we will obtain the projection of the area: The projection consists practically in obtaining an average of the brightness values of an area and listing them on a line.
  • Page 152 SCS1 Series Instruction Manual 12.7.2. Contrast detection The detection is not based on the intensity flow but on its derivative. The edge is tracked analysing the brightness difference between two adjacent pixels. The edge is associated to the point where the derivative curve assumes a maximum (positive edge) or a minimum (negative edge) value.
  • Page 153 Instruction Manual SCS1 Series 12.8. Pattern match Pattern match consists in locating similar patterns between a template and a target-object to inspect. The light characteristics inside a specific area have been saved. Each template pixel corresponds to a specific brightness value represented by a grey level (0-255).
