Re: [ros-users] Problem with canonical_scan_matcher

Hi Eric,

Were there any people moving around in the laser scan while the robot was
stationary?
During the experiement, i tried to isolate the robot so that the environment
remained unchanged throughout the whole experiment.

What does the laser scan look like? Is it noisy?
Personally, i don't think the laser is scan is noisy. I have already
attached the picture of the laser scan for your reference.

Meanwhile, i also tried to change the parameter for "sigma",
"max_correspondence_dist" and "orientation_neighbourhood" to increase
tolerence using these setting

sigma = 1
max_correspondence_dist = 0.4
orientation_neighbourhood = 100

What other parameters would you suggest to enhance the result ?
sorry to trouble you.

With thanks,
Zhiping
