Circle Measure

The Measure Tool in AutoVISION can also be used to measure the radius of a circle and to find its center point. Insert a Measure Tool into your job, and then use the dropdown at the top of the parameter area to select the Circle Measure option.

Circle Shape

The circle shape that appears in the image area allows you to specify both an inner and an outer radius. This shape adjusts the start and end radius values without showing individual vectors. When first inserting a circle measurement, the inner radius will be 0 and the shape will look like this:

 

 

The size of the circle can be increased or decreased. The single anchor point in the center is for the inner radius. Grab the anchor point and drag down to open up the inner radius size as shown below:

 

 

The inner circle is labeled as Circle1:Start, indicating that the edge scan will start here, and the outer circle is labeled Circle1:End, indicating that the edge scan will stop there. The green background arrows are also intended to show the direction in which the edge scan will proceed, which is inside to outside in this example. If you want to scan from the outside to in, simply increase the size of the Circle1:Start circle to make it larger than the Circle1:End circle, as shown here:

 

 

Note that the green arrows now point from the outside in.

 

Parameters

The editors shown below are provided to configure the circle fit.

 

 

 

 

Similar to the Width and Height measurements, a gradient plot editor is provided for setting the minimum edge strength of the vectors. With a Width Measurement, the gradient plot is down the middle of the region of interest, moving from left to right. With a Height measurement, the gradient plot is also down the middle of the region of interest, but moving from top to bottom. With Circle measurement, it is selectable. Note that there is a control on the right that allows you select where the gradient scan is taken within the Circle measurement. If lighting around a given circle is uneven, this allows you to see the gradient values on the left, right, top, and bottom edges of the circle. 

 

 

These are the options for the circle fit, which allows you to select the minimum number of vector edge points required for a valid circle fit, and then allows you to choose how precise that fit must be.

 

 

This is the tolerance on the radius of the circle.

 

Setup Time Feedback

In Edit mode, if the Circle measurement is able to fit a circle, the tool will display the center and the radius of that circle.

 

 

If unable to fit the circle, the tool will notify you and report the number of edge points found:

 

 

In the image, an ‘X’ will be drawn everywhere an edge point is found, and the fit circle will also be drawn:

 

 

Point to Point Measure

These parameters allow you to connect the two input points to output points from any other tool. The standard tolerance editor is also provided to allow the setting of an upper and lower measurement limit:

 

 

 

Outputs

 

Point to Line Measure

These parameters allow you to connect the input point and line to an output point and line from any other tool. The standard tolerance editor is also provided to allow the setting of an upper and lower measurement limit:

 

 

Outputs

 

Calibration

Both the Point to Point and Point to Line distance capabilities can be calibrated, as with other measurements. The Calibration editor will be present in the parameter area for both of these capabilities.

 

Identifying an Edge

 

           

 

Locating Transitions between Light and Dark

          

 

 

 

Fitting an Edge Line to Edge Points

 

Perfect Edge = Accurate edge line placement; stray edge points are ignored.

 

Rough Edge = Edge line placement uses an average of all edge points including stray edges. This is useful when no clearly-defined line is available.

Measure Tool (Width) Advanced Parameters

 

Distance Type is the method used to measure distance between lines.

 

Point-to-Point measures from the center point of Edge1 to the center point of Edge2.

 

Point-to-Line measures the perpendicular distance between the center point of the first edge to the line of the second edge.

 

 

Measure Tool (Height) Advanced Parameters

 

Distance Type is the method used to measure distance between lines.

 

Point-to-Point measures from the center point of Edge1 to the center point of Edge2.

 

Point-to-Line measures the perpendicular distance between the center point of the first edge to the line of the second edge.

 

 

Measure Tool (Circle) Advanced Parameters

 

 

Result Type specifies the type of output and provides a choice between Transitions and Lines:

 

 

 

Edge Point Selection: First, Best, Last, Nth, All. By default, the Circle Fit tool will use the highest-strength edge. This parameter allows you to choose which transition or line along the vector to select.

 

 

 

 

 

 

Enable Radius and Location Filter: Only points that are within the settings of these parameters will be used as inputs to the circle fit.

 

Circle Completeness sets where points on the circle have to be located for circle fit to be generated.
