    pointCloudPcdChunk: Uint8Array

    One chunk of the PointCloud. For a given GetPointCloudMap request, concatenating all GetPointCloudMapResponse.point_cloud_pcd_chunk values in the order received result in the complete pointcloud in standard PCD format where XY is the ground plane and positive Z is up, following the Right Hand Rule.

    Read more about the pointcloud format in the docs

    Viam expects pointcloud data with fields "x y z" or "x y z rgb", and for this to be specified in the pointcloud header in the FIELDS entry. If color data is included in the pointcloud, Viam's services assume that the color value encodes a confidence score for that data point. Viam expects the confidence score to be encoded in the blue parameter of the RGB value, on a scale from 1-100.

    Pointclouds are little endian encoded.

    Methods

    • Parse from binary data, merging fields.

      Repeated fields are appended. Map entries are added, overwriting existing keys.

      If a message field is already present, it will be merged with the new data.

      Parameters

      • bytes: Uint8Array
      • Optionaloptions: Partial<BinaryReadOptions>

      Returns this

    • Parse a message from a JSON value.

      Parameters

      • jsonValue: JsonValue
      • Optionaloptions: Partial<JsonReadOptions>

      Returns this

    • Parse a message from a JSON string.

      Parameters

      • jsonString: string
      • Optionaloptions: Partial<JsonReadOptions>

      Returns this

    • Retrieve the MessageType of this message - a singleton that represents the protobuf message declaration and provides metadata for reflection- based operations.

      Returns MessageType<GetPointCloudMapResponse>

    • Serialize the message to binary data.

      Parameters

      • Optionaloptions: Partial<BinaryWriteOptions>

      Returns Uint8Array

    • Serialize the message to a JSON value, a JavaScript value that can be passed to JSON.stringify().

      Parameters

      • Optionaloptions: Partial<JsonWriteOptions>

      Returns JsonValue

    • Override for serialization behavior. This will be invoked when calling JSON.stringify on this message (i.e. JSON.stringify(msg)).

      Note that this will not serialize google.protobuf.Any with a packed message because the protobuf JSON format specifies that it needs to be unpacked, and this is only possible with a type registry to look up the message type. As a result, attempting to serialize a message with this type will throw an Error.

      This method is protected because you should not need to invoke it directly -- instead use JSON.stringify or toJsonString for stringified JSON. Alternatively, if actual JSON is desired, you should use toJson.

      Returns JsonValue

    • Serialize the message to a JSON string.

      Parameters

      • Optionaloptions: Partial<JsonWriteStringOptions>

      Returns string
