在 C# 中使用 Halcon 13 函数 FindNccModel 会导致以下错误:HALCON error #6001: Not enough memory available in operator find_ncc_model

该函数本身可以在一个while循环中无限运行,但如果它与我们的程序结合使用会导致内存异常。另一方面,程序本身可以在没有此功能的情况下无限运行。有趣的是,错误发生在程序达到典型的 1,1 Gb 内存之前,这意味着存在内存泄漏。
我在 Halcon 文档中没有找到任何关于此问题的参考,升级到最新的 Halcon 13 版本或使用 Halcon XL 没有帮助。有谁知道什么可能导致这个问题?
