在颤振中，使用AR即时测试墙壁上的颜色是可能的

Question

我想改变飘动中墙壁的颜色，这是否可能，如果可能，请分享文章和任何注释。感谢

Answer 1

我认为这是可能的。

首先，使用tflite: ^1.1.2来检测墙壁，然后使用ar_flutter_plugin: ^0.6.2来制作类似墙壁的形状并改变其颜色。

示例：

使用camera和tflite插件的Flutter中的Real-time object detection。例如Link

使用ar_flutter_plugin制作墙壁

import 'dart:async';
import 'dart:ffi';
import 'dart:math';
import 'package:arkit_plugin/arkit_plugin.dart';
import 'package:flutter/material.dart';
import 'package:vector_math/vector_math_64.dart' as vector;
void main() {
runApp(MaterialApp(home: MyApp()));
}

typedef AnimateTo = double;
class CubeWall {
final ARKitController controller;
final list = <ARKitNode>[];
var num = 144;
var l = 0.02;
late var rect = ARKitBox(width: l* 1.05, height: l * 1.05, length: l * 1.05);
var rng = Random();
var animations = <int, AnimateTo>{};
CubeWall(this.controller) {
for(int i = 0 ; i < num; i++) {
var x = 1.41 * l * (i % 12);
int n = (i / 12).floor();
if (n.isEven) {
x = x + l * 0.705;
}
var y = -(l * 0.69) * n;
var z = (l * 0.97) * n;
final node = ARKitNode(
geometry: rect,
position: vector.Vector3(x, y, z),
eulerAngles: vector.Vector3(pi / 4.0, 0, 0),
);
controller.add(node);
list.add(node);
}
}
}
class MyApp extends StatefulWidget {
@override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
late ARKitController arkitController;
ARKitReferenceNode? node;
Timer? timer;
@override
void dispose() {
arkitController.dispose();
super.dispose();
}
@override
Widget build(BuildContext context) => Scaffold(
appBar: AppBar(title: const Text('Coming Text')),
body: Container(
child: 
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Expanded(
child: ARKitSceneView(
onARKitViewCreated: onARKitViewCreated,
),
),
]),
),
);
void onARKitViewCreated(ARKitController arkitController) {
this.arkitController = arkitController;
CubeWall(arkitController); 
}
}
