LASER RANGING APPARATUS, CAMERA APPARATUS AND TERMINAL

WIPO Patent Application WO/2017/124743

A1

A laser ranging apparatus (100), a camera apparatus and a terminal thereof, comprising a shell (11), a laser ranging sensor (12) and a cover plate (13), wherein the shell (11) is provided with a light-transmitting window (111); the laser ranging sensor (12) is mounted in the light-transmitting window (111), and a light emitter (121) and a light receiver (122) are provided at intervals in the laser ranging sensor (12); the light emitter (121) emits a light beam to an object to be measured via the cover plate (13) and receives same by means of reflecting the light beam through the object to be measured and penetrating same through the cover plate (13) to the light receiver (122); the cover plate (13) is embedded in the light-transmitting window (111); and a light blocking member (14) is provided between the cover plate (13) and the light-transmitting window (111). The light blocking member (14) is used to block a light beam emitted by the light emitter (121) to a place between the cover plate (13) and the light-transmitting window (111), so as to prevent crosstalk caused to the emission and reception of an infrared ray due to the reflection of the light beam to the light receiver (122), and ensure the accuracy of the laser ranging sensor (12) for a target distance measurement result.
