Title:
LASER DISTANCE MEASUREMENT DEVICE AND ROBOT
Document Type and Number:
WIPO Patent Application WO/2021/109912
Kind Code:
A1
Abstract:
Disclosed are a laser distance measurement device (1) and a robot. The laser distance measurement device (1) comprises a transmitting unit (11) and a receiving unit (12). The transmitting unit (11) comprises a transmitter (111) for transmitting a pulse laser to a target object to be subjected to distance measurement, and a transmitting lens (113) for allowing the transmitted pulse laser to pass through same. The receiving unit (12) comprises a photodetector (121) for receiving the pulsed laser reflected from the target object, and a receiving lens (123) used for allowing the reflected pulsed laser to pass through same. The field of view of the receiving unit (12) is greater than that of the transmitting unit (11), and the distance between the outer edge of the receiving lens (123) and the outer edge of the transmitting lens (113) is less than or equal to 3 mm. The laser distance measurement device (1) and the robot are suitable for carrying out short-distance, high-frequency distance measurement in an indoor environment by means of a time-of-flight method, and the distance measurement precision is higher and the cost is lower.
