OPT3101: Will it be swept to the ground because of the large FOV angle, resulting in false alarms? FOV angle is 120 °

Part Number: OPT3101


Hi Engineer

1. AGV anti-collision demand, detecting the area in front of the AGV car.
Detection time: within 10ms.
Detection range: X-axis ± 0.5 m, Y-axis 1.5 m, FOV angle is 120 °.
Question: The AGV car is much larger than the sweeping robot. Because the TOF camera is placed at a lower position, it is necessary to increase the FOV angle. Will it be swept to the ground because of the large FOV angle, resulting in false alarms?
This problem did not exist with Lidar previously.
2. Does the AGV used in industrial applications need to increase the external temperature sensor?
3. Is there an instance of the register configuration method? I plan to use the FPGA to manage the OPT3101.
4. Where is this chip used? Does this chip have a precedent for use on AGV?

Thanks a lot.

    Hi Elsa,

    Can you provide details on the AGV car? Is this something like a forklift? Would you be able to provide a diagram showing the axes you mentioned and position of the sensor, I'm not sure what you mean by x-axis spec.

    I'd also like to clarify since you said "TOF camera", OPT3101 is a ranging device with three channels, but it will not provide a depth map like an image. It will give one distance reading per channel. 

    To try to give some answers based on what you provided

    1) When you say "Will it be swept to the ground because of the large FOV angle, resulting in false alarms?" I am assuming this is asking if the sensor will detect the ground being placed near the bottom of the vehicle. This is true. However, it is possible to add a baffle to block light in the downward direction to address this. Also want to clarify since you said "swept" that OPT3101 can achieve 120 degree FoV (3x 40 degree FoV) without needing to move the sensor emitter or sweep side to side like a LiDAR.

    2) can you clarify this question please?

    3) Please see our SDK and configurator tool posted online. Configurator tool will output register settings in cpp file for SDK, but you could use this output to pull out the register settings

    4) OPT3101 is used for a number of applications involving collision avoidance

    Best,

    Alex
