A device for rapidly and comprehensively inspecting a lens actuator, comprising a bracket for fixing the lens actuator, a cone-shaped body, and a camera, characterized in that: the device is configured for the lens actuator to be arranged on the bracket to place the cone-shaped body inside a lens holder of the lens actuator; the camera, configured to capture a characteristic image which is in the lens holder and reflected by the cone-shaped body; and further configured to capture the same characteristic image which is in the lens holder and reflected by the cone-shaped body again after the stroke and/or the tilt angle of the lens holder is/are changed; the following calculation is performed according to the change of the image captured by the camera and corresponding to the characteristic image in the lens holder: d i − e i = Δ d i = k Δ p i, i ∈ 1, 4 wherein, d i is a current distance between the bottom of the lens holder and the bracket, and e i is a distance between the bottom of the lens holder and the bracket in the case that the stroke and/or the tilt angle of the lens holder is/are not changed; Δ p i is the change of the position of the characteristic image in the captured image in the case that the stroke and/or the tilt angle of the lens holder is/are changed relative to the position of the characteristic image in the captured image in the case that the stroke and/or the tilt angle of the lens holder is/are not changed, the measurement unit of Δ p i is pixel, and k is a relationship coefficient between pixels and a physical distance of an objective; the stroke S and the tilt angles θ x and θ y of the lens holder is obtained according to Δ d i through the following calculation: S = Δ d i / 4 θ x = tan − 1 d 3 − d 4 / a θ y = tan − 1 d 1 − d 2 / a wherein, a is the diameter of the lens holder; d 1 is a distance between the highest point of the bottom of the lens holder and the bracket when the lens holder is in a first position, and d 2 is a distance between the lowest point of the bottom of the lens holder and the bracket when the lens holder is in the first position; d 3 is a distance between the highest point of the bottom of the lens holder and the bracket when the lens holder is in a second position, and d 4 is a distance between the lowest point of the bottom of the lens holder and the bracket when the lens holder is in the second position; wherein, the outer surface of the cone-shaped body is a mirror surface, the cone-shaped body is mounted on the top of the bracket, and the camera is hung above the cone-shaped body. the device is configured for the lens actuator to be arranged on the bracket to place the cone-shaped body inside a lens holder of the lens actuator; the camera, configured to capture a characteristic image which is in the lens holder and reflected by the cone-shaped body; and further configured to capture the same characteristic image which is in the lens holder and reflected by the cone-shaped body again after the stroke and/or the tilt angle of the lens holder is/are changed; the following calculation is performed according to the change of the image captured by the camera and corresponding to the characteristic image in the lens holder: d i − e i = Δ d i = k Δ p i, i ∈ 1, 4 wherein, d i is a current distance between the bottom of the lens holder and the bracket, and e i is a distance between the bottom of the lens holder and the bracket in the case that the stroke and/or the tilt angle of the lens holder is/are not changed; Δ p i is the change of the position of the characteristic image in the captured image in the case that the stroke and/or the tilt angle of the lens holder is/are changed relative to the position of the characteristic image in the captured image in the case that the stroke and/or the tilt angle of the lens holder is/are not changed, the measurement unit of Δ p i is pixel, and k is a relationship coefficient between pixels and a physical distance of an objective; the stroke S and the tilt angles θ x and θ y of the lens holder is obtained according to Δ d i through the following calculation: S = Δ d i / 4 θ x = tan − 1 d 3 − d 4 / a θ y = tan − 1 d 1 − d 2 / a wherein, a is the diameter of the lens holder; d 1 is a distance between the highest point of the bottom of the lens holder and the bracket when the lens holder is in a first position, and d 2 is a distance between the lowest point of the bottom of the lens holder and the bracket when the lens holder is in the first position; d 3 is a distance between the highest point of the bottom of the lens holder and the bracket when the lens holder is in a second position, and d 4 is a distance between the lowest point of the bottom of the lens holder and the bracket when the lens holder is in the second position; wherein, the outer surface of the cone-shaped body is a mirror surface, the cone-shaped body is mounted on the top of the bracket, and the camera is hung above the cone-shaped body.
