cocos creator 射线检测问题

[geiwoyipiao (Eaglesmvp)]

现在想做的是计算3D世界空间坐标下屏幕边界的位置，通过点击事件发送射线检测的结果是正确的，但是通过一个固定的数据检测的时候，检测的结果不正确。下面是代码：
预格式化文本将缩进 4 格`import { _decorator, Camera, Component, EventTouch, geometry, Input, input, Node, PhysicsSystem, view } from ‘cc’;
const { ccclass, property } = _decorator;

@ccclass(‘UIManager’)
export class UIManager extends Component {

@property(Camera)
d3Camera: Camera = null;

start() {
    this._checkBoard();
}

private _checkBoard() {
    const viewSize = view.getVisibleSize();
    let ray = new geometry.Ray();
    this.d3Camera.screenPointToRay(viewSize.width,viewSize.height,ray);

    const hasRes = PhysicsSystem.instance.raycast(ray);
    if(hasRes) {
        const res = PhysicsSystem.instance.raycastResults;
        res.forEach(item => {
            console.log("hitpoint is ",item.hitPoint);
            console.log("hitnode name is ",item.collider.node.name);
        });
    }
}

protected onEnable(): void {
    input.on(Input.EventType.TOUCH_START,this.tapStart,this);
}

protected onDisable(): void {
    input.off(Input.EventType.TOUCH_START,this.tapStart,this);
}

public tapStart(event: EventTouch){
    const pos = event.getUILocation();
    console.log("pos is ",pos);

    const ray = new geometry.Ray();
    this.d3Camera.screenPointToRay(pos.x,pos.y,ray);

    const hasRes = PhysicsSystem.instance.raycast(ray);
    if(hasRes) {
        const res = PhysicsSystem.instance.raycastResults;
        res.forEach(item => {
            console.log("hitpoint is ",item.hitPoint);
            console.log("hitnode name is ",item.collider.node.name);
        });
    }

}

update(deltaTime: number) {
    
}

}

代码中是首先调用了检测边界的方法，不是通过touch事件进行射线检测的，但是检测结果与点击事件检测的结果不同，截图如下：
