Hello Everyone ,
I am using VLP16 for navigation application. What is minimum range for vlp16 to detect. Is there any way to reduce it.? This is making an issue to avoid obstacle that are inside this range
The VLP16 programming guide mentions that the effective range for a VLP16 is from 1 meters to a 100 but I have seen some reference which says it is about 90 cm. I don’t think this can be reduced.
Here’s an excerpt from an app note on a “short distance” feature. You could get different results sensor-to-sensor and the values in this range are not subject to accuracy specifications. It would be advisable to validate you get the desired response from any sensor used in this mode:
Overview
The VLP-16 hardware has been updated to allow range measurements as low as 0.1 meters instead of the default 0.5 meters. This feature needs to be enabled by the customer and is OFF by default. The reason it is shipped in the default mode “OFF” is that measurements below 0.5 meters are NOT calibrated.
Description of Feature
By default, the VLP-16 provides measurements from a minimum distance of 0.5 meters. The short distance measurement feature enables returns from distances as low as 0.1 meters. The accuracy of these measurements is subject to much more variability because the sensor is not calibrated at distances of less than 0.5 meters. Therefore, customers using this feature to view returns below 0.5 meters should assume the possibility of more distance accuracy error than normal.
This feature is off by default and may be enabled with the following command: curl http://192.168.1.201/cgi/short_dist-data “enable=On”
Note that there is no web interface equivalent, by design.
Likewise, it may be disabled with the following command:
curl htp://192.168.1.201/ci/short_dist–data “enable=Off”
To determine if this setting is on, the following curl command may be used:
curl http://192.168.1.201/cgi/short_dist.json
The return JSON string is
“short_dist”:(“enable”:“On”} or “short_dist”:(“enable”:“Off”}
