The invention discloses an angular point measuring device of a passenger car and an angular point measuring method. The angular point measuring device comprises a base, a support arranged on the base and a measuring panel arranged on the support. The base comprises two parallelly arranged guide tracks, a plurality of connecting rods are arranged between the guide tracks, the support comprises a beam and a lifting column, the beam is erected on the guide tracks and can move along the beam, the beam and the guide tracks form a 60-degree included angle, and the measuring panel is arranged on the column and perpendicular to a track plane. A two-dimensional movable measuring platform is adopted for simulating a collision process between pedestrians and a front bumper of the car so as to determine angular point positions. Determination of an angular point is changed into a direct collision measuring method from an indirect method through original laser radiation and observation of naked eyes, locating of angular points in a collision area of shanks of pedestrians in a pedestrian protection test is fully achieved, a measuring process is simple, and the measuring precision is high.
