But because of small deviations between parts and the need to guide the laser beam precisely onto the seam edge, pre-process edge tracking
needs to be implemented.
Table 1 summarizes the commonly used algorithms for retinal OCT image segmentation, including the Canny edge detector [12,13], two-pass edge detection method [14, 15], local mean gradient-based edge tracking
, peak detection method, Gaussian smoothing in combination with the Sobel kernel method [17, 18], and EdgeFlow technique .
by hysteresis: Final edges are determined by suppressing all edges that are not connected to a very certain (strong) edge.
They are smoothing, finding gradients, non-maximum suppression, double thresholding and edge tracking
Other sensing and control systems include Decoding, Distortion Monitoring, Length Position and Control, Automatic Edge Tracking
and Edge Crack Detection.
An extracted edge from a once-binarized right hand image will contain bifurcation, which may disturb fingertip detection that uses edge tracking
. To solve this problem, a once-binarized right hand image is blurred by using a 7 x 7 average filter, as shown in Figure 5(b).
The DC3000 can operate with Automatic or Fixed Edge Tracking
and can have up to 200 individual Product Records used for configuration.
TomTom WORK combines industry leading communication and smart navigation technology with leading edge tracking
and tracing expertise.
Laser line sensors are ideal for thickness profiling and edge tracking
. For tread profiling, laser line sensors eliminate transverse scanning frames for smaller parts and enhance data collection during a sweep for higher automation intelligence and control.
We interpret the one successful Algorithm 2 hit from the 100 cm starting distance as a chance event, and the hits from the 60 cm starting distance as successful plume edge tracking
. Consequently, we conclude that sensor signal difference is adequate for guidance in the proximal jet, but that some other form of information (i.e., more widely separated sensors, a sense of the mean flow or more detailed analysis of the temporal structure of odor distribution) is required to navigate the distal patch field to a turbulent jet source.
The OCT scanner is coaxially coupled in the weld scanner to employ ultra-fast workpiece scanning, allowing it to provide integrated edge tracking
and seam topology measurement.
The process is complemented with cutting edge tracking
and reporting tools.
