Abstract

The present application discloses a method and device for measuring time of flight and a LiDAR, and belongs to the field of ranging. In the present application, because a shared device of a first transmission link and a second transmission link is a temperature-sensitive device, the delay time of the temperature-sensitive device may be eliminated according to the differential processing of first transmission time and second transmission time. Thus the measurement results of the time of flight are only related to the delay time of the non-temperature sensitive device, thereby reducing the problem of the inaccurate measurement of the time of flight of a target object caused by the temperature change of a device for measuring. Therefore, the accuracy of the measurement of the time of flight of the device for measuring is improved.

Abstract

An embodiment of this application discloses a laser emitting circuit and a LiDAR, and belongs to the field of the LiDAR. The structure of the laser emitting circuit is changed so that for the laser emitting circuit in an energy transfer stage, the energy transfer current from an energy storage element does not pass through a laser diode, and the laser diode is in a reverse-biased state relative to the energy transfer current. Therefore, the parasitic capacitance of an energy releasing switch element does not cause the laser diode to emit light in advance during an energy transfer charging process, which prevents the laser diode from emitting light at an unanticipated time, thereby solving the problem of laser leakage.

Abstract

A lidar, and an anti-interference method therefor, may modulate a transmitting time of the lidar by injecting random time jitter at a time interval in a sequence of the transmitting time, and cause the lidar to transmit a laser pulse according to a modulated transmitting time. When an echo received by the lidar includes an expected echo of the local lidar and an unexpected echo from other lidars, because the transmitting time and the expected receiving time of the echo are correlated, injecting random time jitter in the transmitting time of the lidar may disrupt the correlation between the transmitting time of the local lidar and the transmitting time of other lidars. Thus, when a plurality of lasers are used together in one scenario and cause crosstalk, the anti-interference method for the lidar above can be used to fight against crosstalk to some extent.

The hardware part comprises an optical collimation system, an FPGA, a filter, a photoelectric conversion system, an analog amplifier circuit, a laser transmitter, a signal combination system, an ADC sampling system and a narrow pulse laser transmitting circuit. When transmitting a control signal to control laser transmission, the FPGA sends a time reference pulse to the signal combination system. The signal combination system integrates the time reference pulse with a fixed amplitude analog echo signal to form an echo signal with a time reference. The echo signal with a time reference is quantified into a digital detection signal in the ADC sampling system. The digital detection signal is sent to the FPGA to undergo data analysis. The software part is used to perform time domain waveform matching analysis to obtain a ranging result. The ranging result is output by the FPGA.
