Laser scanning provides a quick way to get images of buildings or machines for different purposes, such as detecting defects. People who are planning to use this scanning equipment during construction projects can tweak the settings of that machine in order to scan the desired structures faster without sacrificing quality. This article discusses some of the adjustments which can increase the productivity of the laser scanner.
The Scan Resolution
You can change how detailed the scan results should be in order to complete the process of scanning quickly. For example, the space between the scan lines on the Y-axis affects how quickly the scans are obtained. Reducing the resolution (by increasing the space between the lines) can shorten the time required for each scan. However, it is advisable to find a defective section of the building and keep adjusting the resolution to the point when the defect can no longer be shown by the scan results. That point should then set the limit beyond which the resolution should not be reduced.
The Number of Scans
Laser scanners usually run multiple scans of an object or structure in order to gather sufficient data for processing by the software programme to which the scanner is attached. Reducing the number of scans that should be performed during each run of the machine can increase the speed at which results are obtained.
The laser scanner has motors that control the action of the scanner along the different axes (X-axis and Y-axis). The machine can become quicker if the speed at which the motors rotate is increased. This will result in a shorter time to perform each scan without sacrificing the quality of the resultant scan data. However, the laser scanner may need to be left to cool down for a while after an extended session of using it at high motor speeds.
Field Depth Compression
The field depth refers to how wide the area captured by the scanner is. Wider areas take longer to scan because the machine has to collect a lot of data before moving on. Compressing the field depth allows the machine to work faster because its view will be concentrated at a narrower angle. For example, the scanner can have its field depth compressed if the area of interest is only the point where the floor meets the wall. Defects in the placement of floor tiles in that area can be discovered without gathering data from an area which is several feet wide.
As you can see, you should not worry about the hourly rate of the technical people handling the laser scanning equipment. Ask them to optimise the speed of their machines so that you can obtain reliable results quickly.
