The target distance is computed with knowledge about the target size and the camera optics. Note 2: In LabVIEW this information is calculated using the vertical target in order to apply to both Hot and Not Hot targets. Note: In the C++ and Java example, this information is provided by using the Normalized Center of mass from the target report for the horizontal or vertical target particle. This coordinate system is useful because it has a centered origin and the scale is similar to joystick outputs and RobotDrive inputs. This could be corrected by multiplying the point by (Note: this is not done in the sample code). The resulting coordinates are close to what you may want, but the Y axis is inverted. To convert a point from the pixel system to the aiming system, we can use the formula shown below. This is a useful system for pixel math, but not nearly as useful for driving a robot so let’s change it to something that may be more useful. The target position is well described by both the particle and the bounding box, but all coordinates are in pixels with 0,0 being at the top left of the screen and the right and bottom edges determined by the camera resolution. Another reason to use the HSV color system is that the thresholding operation used in the example runs more efficiently on the cRIO when done in the HSV color space. The primary reason is that it readily allows for using the brightness of the targets relative to the rest of the image as a filtering criteria by using the Value (HSV) or Luminance (HSL) component.

The example code uses the HSV color space to specify the color of the arget. Luminance or Value indicates the shade of gray that the hue is blended with. Zero saturation has no hue and is completely gray. Higher ratio means more colorful, less gray. Saturation of a color specifies amount of color, or the ratio of the hue color to a shade of gray. The hue is specified using a radial angle on the wheel, but in imaging the circle typically contains only 256 units, starting with red at zero, cycling through the rainbow, and wrapping back to red at the upper end. Later, we went to lunch at a Chinese restaurant, discussing the issues and planning for the work that we were going to do in the workshop later.The Hue or tone of the color is commonly seen on the artist’s color wheel and contains the colors of the rainbow Red, Orange, Yellow, Green, Blue, Indigo, and Violet. After the tour, we discussed our scissor lift with an engineer known as “Mud Dude.” We also got to see one of our brackets being Waterjetted. Next we went to Haskel Zeloof’s company, Diversatech, to see the shop, a prototype design for our scissor lift and demonstrations of the Waterjet and CNC Turret punch (videos below). We also got to see prototypes in the next room, being made to control stage props in a theater, using Mecanum wheels. For example, there is a product that is used to determine if a child will get a head injury from falling from a certain height, on a playground surface. We saw many cool things, like the PCB Board Machine, (video below) which made PCB boards without the need of a person soldering on each individual component. This company specializes in circuits, control systems and automation. First, we went to Paul Bamburak’s company, Alpha Automation.

So, today was a very full day! FIRST Team 3637 visited, and toured, two of our Mentors’ businesses.
