The invention relates to a bridge deflection-corner integrated measurement method, comprising the following steps: fixing a signal transmitter A at the structural deflection measurement point of the structure to be measured of the bridge, and guaranteeing that the light paths of two laser transmitters of the signal transmitter A are emitted in the opposite direction of the longitudinal direction of the bridge; fixing a set of signal acquisition devices B at the stationary reference points on both sides of the bridge, respectively, and enabling the laser emitted by the signal transmitter A to be received by the receiving screen of the signal acquisition devices B; connecting the two signal acquisition devices B with a computer C; and enabling the computer C to synchronously acquire light spot data at a fixed frequency and perform calculation processing on the light spot displacement. The measurement method provided by the invention solves the problem of errors caused by the laser corners by symmetrically arranging the laser transmitters at the deflection measurement point of the structure to be measured; and the deflection and the corners are measured simultaneously at one measurement point; the laser transmitters are fixedly connected with the part to be measured without degree of freedom; and the image acquisition devices are capable of performing dynamic measurement while acquiring the laser light spot images at a fixed frequency.
