摘要
进行精密水准测量时,视距是制约生产效率的最关键因素。通过扩大数字水准仪条码尺的码宽,在满足精密水准测量精度的前提下,可以有效地扩大精密水准测量的视距。研究扩大条码尺码宽时数字水准仪的测量原理,并利用喷绘的条码尺进行初步试验。
Sighting distance is a key factor to restrict the production efficiency from precise leveling. It is needed to increase the sighting distance by amplifying the barcode for precise leveling. It presents the measuring principles of amplifying barcode for digital level and shows the test results by using the painting barcode staff.
