Long distance cross river elevation measurement is a widely concerned issue in water conservancy infrastructure projects. This article utilizes the automatic alignment measurement function of high-precision measurement robots and adopts the quadrilateral method of precise trigonometric leveling for long-distance cross river elevation measurement. The operation principle, measurement steps, and main error factors are analyzed and studied. And through the engineering example, the accuracy of the height control meas-urement results of this method is comprehensively analyzed, and it is verified that the quadrilateral method can meet the requirements of second order leveling accuracy, and provides a more reliable solution for long-distance river-cross leveling.
